# AGENTS.md
## Quick start
```bash
cargo build --release && ./target/release/dcr setup
```
## Pre-PR (CI) gate
```bash
cargo fmt --all --check
cargo clippy --all-targets --all-features -- -D warnings
cargo check --all-targets --all-features
cargo test
```
CI (`.github/workflows/ci.yml`) runs fmt, clippy, check — **not** tests.
## Tests
- Integration tests in `tests/` build the dcr binary and run it in temp dirs under `sandbox/cli-tests/` (gitignored).
- Some tests **skip** if no C compiler (`gcc`/`clang`/`cc`) is found at runtime.
- Compiler can be overridden via `DCR_COMPILER` or `DCR_CC` env vars.
- Tests use `$CARGO_BIN_EXE_dcr` when available, else `target/debug/dcr`.
## Architecture
- **Single Rust package** (edition 2024), not a workspace. Only one binary: `dcr`.
- **Entrypoint**: `src/main.rs` — matches `args[1]` against command names.
- **Compiler backends** in `src/core/builder/`: `unix_cc` (gcc/clang), `msvc` (cl/clang-cl), `gas`, `nasm`. Dispatched by matching compiler name string.
- **Config**: `dcr.toml` (per-project), `~/.dcr/config.toml` (registry), `~/.dcr/index.json` (index). Defaults: `language=c`, `standard=c11`, `compiler=clang`, `kind=bin`.
- **`build.rs`** embeds `TARGET` as `DCR_TARGET` env var (shown in `--version`).
- **CLI output** must be in English. Use `utils::log` for messaging.
## Key commands
| Command | Notes |
|---|---|
| `dcr new <name>` | Creates project dir |
| `dcr init` | Init from CWD (must be empty) |
| `dcr build [--debug\|--release] [--target <triple>]` | Default profile: `--debug` |
| `dcr run [--debug\|--release]` | Only for `kind = "bin"` |
| `dcr clean [--debug\|--release] [--all]` | `--all` for workspace roots |
| `dcr tree` | Dependency tree viewer |
| `dcr test [--init]` | Runs/test project tests |
| `dcr gen <vscode\|clion\|compile-commands>` | IDE integration |
| `dcr --update` | Self-update from GitHub Releases |
## Cross-compilation
`--target` accepts short names (`linux`, `macos`, `windows`) or full triples. In CI, Linux cross-builds use `cargo-zigbuild`. When `build.target` is set in `dcr.toml`, DCR auto-injects `--target=<value>` into cflags (clang). Bare-metal targets (containing `none`/`-elf`/`eabi`/`baremetal`) skip DCR's default compiler flags.
## Dependencies (Cargo)
reqwest (blocking+json+rustls-tls), serde, toml, git2, openssl (vendored), self-replace, sha2, ctrlc.

# Changelog # Changelog
## [0.8.4] - 2026-08-04 "Инфраструктура .dcr/ и интеграция с IDE / Internal .dcr/ Layout & IDE Integration"
### RU
**Добавлено:**
- **Директория `.dcr/`** — единый machine-readable источник фактов о сборке для IDE/расширений:
- `.dcr/compile_commands.json`
- `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
- `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
- `.dcr/ide/` (заготовки lock-файлов для расширений)
- **`dcr gen project-info`** — поля `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; пути абсолютные/канонические.
- **`dcr build --print-artifact-path`** — после успешной сборки одна строка absolute path на stdout.
- **`dcr gen … --quiet` / `-q`** — без human-лога на stdout для `compile-commands` / `project-info`.
- **`.clangd`** — при первом `gen` создаётся с `CompilationDatabase: .dcr` (маркер `# managed by dcr gen`); ручной `.clangd` не перезаписывается.
- **Хелперы** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` через `platform::*`.
- **`dcr new` / `dcr init`** — `.dcr/` в `.gitignore`.
**Изменено (breaking):**
- **`compile_commands.json` перенесён** из корня проекта в **`.dcr/compile_commands.json`**.
clangd находит базу через `.clangd` / `clangd.arguments --compile-commands-dir=.dcr`.
CLion `misc.xml` и VSCode `settings.json` обновлены под новый путь.
- **Атомарная запись** `compile_commands.json` (tmp + rename).
- **`gen vscode` / `gen clion` launch/run** — `program`/`executable` через тот же artifact resolver, что `project-info` / `build-info.json` (Linux triple, Windows `.exe`, custom `target`/`filename`).
**Исправлено:**
- Launch-конфиги больше не указывают `target/<profile>/<name>` без triple на Linux.
- Симлинки/mount: root и пути в compile database канонизируются best-effort.
### EN
**Added:**
- **`.dcr/` directory** — shared machine-readable build facts for IDE integrations:
- `.dcr/compile_commands.json`
- `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
- `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
- `.dcr/ide/` (placeholder for IDE lock files)
- **`dcr gen project-info`** — `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; absolute/canonical paths.
- **`dcr build --print-artifact-path`** — one absolute artifact path line on stdout after a successful build.
- **`dcr gen … --quiet` / `-q`** — suppress human success logs for gen subcommands.
- **`.clangd`** — created on first gen with `CompilationDatabase: .dcr` (`# managed by dcr gen`); custom `.clangd` is not overwritten.
- **Helpers** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` via `platform::*`.
- **`dcr new` / `dcr init`** — add `.dcr/` to `.gitignore`.
**Changed (breaking):**
- **`compile_commands.json` moved** from project root to **`.dcr/compile_commands.json`**.
clangd discovers it via `.clangd` / `--compile-commands-dir=.dcr`.
CLion and VSCode generators updated accordingly.
- **Atomic write** for compile_commands (tmp + rename).
- **`gen vscode` / `gen clion` launch/run** — use the same artifact path resolver as `project-info` / `build-info.json`.
**Fixed:**
- Launch configs no longer hardcode `target/<profile>/<name>` without the Linux triple segment.
- Symlink/mount roots: best-effort canonicalize for root and compile database paths.
## [0.8.3] - 2026-08-03 "Конфигурация host target, аргументы run и нативные пути артефактов / Host Target Config, Run Args & Native Artifact Paths"
### RU
**Добавлено:**
- **`dcr run -- <args>...`** — cargo-style: всё после bare `--` передаётся собранному бинарнику
(`dcr run --release -- --test_help`). Работает и для прямого запуска, и для `[run].cmd`.
- **Интеграционные / unit-тесты** — host target sections применяют `ldflags` без `--target`; проброс аргументов после `--`; парсер `split_double_dash`.
**Изменено:**
- **Native-сборка резолвит host triple** — без `--target` / без `build.target` конфиг-секции вида
`[build.x86_64-unknown-linux-gnu]` (и аналоги host) снова применяются (`cflags` / `ldflags` / toolchain).
Раньше target был «пустым», секции молча игнорировались, а артефакты уже лежали под host triple — линковка без `-L`/`-l`.
- **Пустой target** — `normalize_target_os("")` больше не warn'ит `Unknown target ''`.
- **`dcr run --help` / man `dcr-run`** — документирован разделитель `--` и forwarding args.
**Исправлено:**
- **Нативные пути артефактов на Windows и macOS** — без явного `--target` / `build.target` артефакты снова сохраняются в `target/<profile>`, поэтому `dcr run` и flat-bin находят результат сборки.
- Target-specific `ldflags` на native Linux/macOS/Windows (host triple) не доходили до линкера.
- Ложный warning на пустой target string.
### EN
**Added:**
- **`dcr run -- <args>...`** — cargo-style: arguments after a bare `--` are forwarded to the built binary
(`dcr run --release -- --test_help`). Works for direct binary runs and `[run].cmd`.
- **Tests** — host target sections apply `ldflags` without CLI `--target`; run-arg forwarding; `split_double_dash` unit tests.
**Changed:**
- **Native builds resolve the host triple** — without `--target` / without package `build.target`, host sections such as
`[build.x86_64-unknown-linux-gnu]` (and host equivalents) apply again (`cflags` / `ldflags` / toolchain).
Previously the target was empty, those sections were silently ignored while artifacts already used the host triple path — link failed without `-L`/`-l` (e.g. sandbox micro-lang + `libsct-elf`).
- **Empty target** — `normalize_target_os("")` no longer warns `Unknown target ''`.
- **`dcr run --help` / man `dcr-run`** — document `--` and argument forwarding.
**Fixed:**
- **Native artifact paths on Windows and macOS** — without an explicit `--target` / `build.target`, artifacts again use `target/<profile>`, so `dcr run` and flat-bin find the build output.
- Target-specific `ldflags` on native host builds not reaching the linker.
- Spurious warning for an empty target string.
## [0.8.2] - 2026-07-22 "CLI Progress, archive Feature, Workspace Path Fixes / CLI Progress, archive Feature, Workspace Path Fixes"
### RU
**Добавлено:**
- **Прогресс компиляции `[N/M]`** — live-строка `compile pkg v0.1.0 [12/41]` на TTY (stderr), чтобы длинные mono-package сборки не выглядели «зависшими».
- **Свой стиль статуса build** — фиксированная колонка глаголов: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run` (не cargo-clone).
- **Cargo feature `archive`** — `fatfs` и упаковка FAT-образов опциональны (`cargo build --features archive`). Release CI собирает с feature; без feature `[archive]` даёт явную ошибку.
- **Интеграционные тесты** — `flat_bin_nasm_build`, `package_build_target_used_without_cli_flag`, усилен workspace `clean --all`.
- **Расширенный CI** — unit + integration на Linux/macOS/Windows, отдельный job с `--features archive`, rust-cache, clippy default + all-features.
**Изменено:**
- **CLI host triple больше не форсится** — без `--target` используется `build.target` пакета/member (важно для bare-metal / post_steps ISO).
- **Relative `-I`/`-L`/`-T` (и `-isystem`/`-idirafter`)** в cflags/ldflags абсолютизируются относительно корня пакета (workspace CWD = root).
- **`dcr clean --all`** — не спамит `target not found` по members без локального `target/` (общий root `target/`).
- **`error` / `warn`** — красный / жёлтый, вывод на stderr; `Подсказка:` → `Hint:`.
- **`dcr --help` / man** — добавлены `add`, `lint`, `setup`; unknown command → exit code 1.
- **Сообщения NotFound** — `linker not found: ld.lld …` / `{tool} not found …` вместо сырого `os error 2`.
### EN
**Added:**
- **Compile progress `[N/M]`** — live TTY line `compile pkg v0.1.0 [12/41]` so long mono-package builds do not look hung.
- **DCR status verbs** — fixed-width column: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run`.
- **Cargo feature `archive`** — optional `fatfs` / FAT packing (`cargo build --features archive`). Release CI builds with the feature; without it `[archive]` errors clearly.
- **Integration tests** — `flat_bin_nasm_build`, package `build.target` without CLI flag, stricter workspace `clean --all`.
- **Expanded CI** — unit + integration on Linux/macOS/Windows, archive feature job, rust-cache, clippy default + all-features.
**Changed:**
- **CLI no longer forces host triple** — without `--target`, package/member `build.target` is used (bare-metal / ISO post_steps).
- **Relative `-I`/`-L`/`-T` (and `-isystem`/`-idirafter`)** in flags are absolutized against the package root when workspace CWD is the root.
- **`dcr clean --all`** — no spam for members without a local `target/` (shared root `target/`).
- **`error` / `warn`** — red / yellow on stderr; Russian `Подсказка:` → `Hint:`.
- **`dcr --help` / man** — list `add`, `lint`, `setup`; unknown command exits 1.
- **NotFound messages** — `linker not found: ld.lld …` / `{tool} not found …` instead of raw `os error 2`.
## [0.8.1] - 2026-07-20 "OS-Dev: flat-bin, FAT-образы / OS-Dev: flat-bin & FAT Images"
### RU
**Добавлено:**
- **`build.kind = "flat-bin"`** — сырой бинарный артефакт (расширение по умолчанию `.bin`):
- **NASM** — `-f bin`, прямой вывод `<stem>.bin`
- **FASM** — прямой вывод (ожидается `format binary` в исходнике)
- **GAS / MASM / LLVM IR (`llc`)** — объект → `objcopy -O binary` → `<stem>.bin`
- **C/C++ (gcc/clang/MSVC)** — compile → link (nostdlib/static) → `objcopy -O binary` → `<name>.bin`
- Требуется `llvm-objcopy` / `objcopy` / `gobjcopy` в PATH (кроме NASM/FASM direct)
- **Секция `[archive]`** — после успешной сборки DCR собирает образ диска (FAT12/16/32): размер, offset, volume label, опциональный bootsector и `layout`. С 0.8.2 — за feature `archive`.
- **Одиночные файлы в `build.roots`** — корень может быть файлом (`.c`, `.asm`, header), а не только каталогом.
**Изменено:**
- **`dcr build --force` / `dcr run --force`** — force также перезапускает `build.steps` и `build.post_steps`.
- **`dcr run` на workspace-only root** — если задан `[run].cmd`, сначала build + run по конфигу корня; иначе делегирование члену workspace.
### EN
**Added:**
- **`build.kind = "flat-bin"`** — raw binary (default `.bin`) across NASM/FASM/GAS/MASM/LLC and C/C++ (objcopy where needed).
- **`[archive]` section** — FAT12/16/32 disk images after build (from 0.8.2 gated by feature `archive`).
- **Single-file `build.roots`**.
**Changed:**
- **`--force`** re-runs steps/post_steps; workspace-only **`dcr run`** prefers root `[run].cmd` when set.
## [0.8.0] - 2026-07-18 "Модульный Движок Сборки, Новая Архитектура Ядра и Улучшение Workspaces / Modular Build Engine, New Core Architecture, & Workspace Improvements"
### RU
**Добавлено:**
- **Выделенное ядро сборки (Build Engine extraction)** — вся логика оркестрации компиляции и сборки полностью вынесена из интерфейсного модуля `src/cli/build.rs` в изолированный, переиспользуемый модуль ядра `src/core/build/engine.rs`.
- **Полиморфная модель языков (Трейт `Language`)** — введение абстрактного трейта `Language` (`src/core/build/language/mod.rs`). Логика поиска файлов, сопоставления расширений и компиляторов распределена по выделенным языковым бэкендам для C, C++ (включая шаги генерации Qt), LLVM IR и ассемблера (GAS, NASM, FASM, MASM).
- **Абстракция сборщиков (Трейт `Builder`)** — введение трейта `Builder` для полиморфного управления процессами компиляции (`src/core/build/builder/mod.rs`). Логика вызова компиляторов семейства GCC/Clang вынесена в общий модуль `builder/cc_common.rs`, а MSVC — в `builder/msvc/`.
- **Поязыковая конфигурация (`[build.<lang>]`)** — добавлена поддержка индивидуальных настроек для каждого языка в `dcr.toml` (например, `[build.c]`, `[build.cpp]`, `[build.asm]`), позволяя независимо настраивать компилятор, стандарт и флаги сборки.
- **Интеграция путей зависимостей в Workspaces** — сборщик теперь автоматически инжектирует пути заголовков (включая исходники `src/` членов, папки `include/` и директорию `target/include`) и библиотек (`target/lib`, а также специфичные для целевой платформы папки сборки) зависимых членов workspace при сборке.
- **Система событий `BuildReporter`** — весь вывод сборщика переведён на событийную модель (`src/core/build/report.rs`), что делает движок пригодным для программного встраивания (например, в IDE) без необходимости перехвата stdout/stderr.
- **Поддержка отмены сборки** — добавлен потокобезопасный токен отмены (`Arc<AtomicBool>`), позволяющий безопасно прервать выполнение компиляции на любом этапе.
- **Сохранение кастомных ключей TOML** — парсер `dcr.toml` переведен на `toml_edit`, что гарантирует сохранение всех неизвестных/пользовательских ключей, комментариев и форматирования при перезаписи файла (например, через `dcr add`).
- **Разрешение заголовков для локальных path-зависимостей** — исправлена проблема, при которой потребители не могли найти заголовочные файлы статических/динамических библиотек, лежащие в упакованной папке `target/include` локальных path-зависимостей.
- **Новая система интеграционных тестов** — старый громоздкий файл `tests/cli_basic.rs` разделен на изолированные и структурированные интеграционные тесты для каждой команды и фичи: `cli_build.rs`, `cli_deps.rs`, `cli_lint.rs`, `cli_new.rs`, `cli_qt.rs`, `cli_test.rs`, `cli_workspace.rs`.
**Изменено:**
- **Дедупликация генерации артефактов** — логика линковки бинарных файлов (ELF, PE, EXE), динамических библиотек (`.so`, `.dll`, `.dylib`) и архивации статических библиотек (`.a`, `.lib`) полностью перенесена в выделенный модуль `src/core/build/builder/artifact.rs`.
- **Запуск членов workspace из корня** — команда `dcr run` при вызове из корня workspace-only проекта теперь запускает сборку выбранного пакета в контексте workspace (через флаг `--workspace`), исключая изолированные ошибки сборки.
- **Отказ от глобального состояния** — все операции сборки изолированы внутри структуры `BuildContext`, обеспечивая многопоточную безопасность сборщика.
- **Вынос логики кэширования** — проверка инкрементальных изменений, отслеживание заголовков (`#include`) и вычисление хэшей сборки перенесено в изолированный модуль `src/core/build/cache.rs`.
- **Модуляризация кастомных шагов** — обработка этапа `build.steps` для препроцессоров вынесена в `src/core/build/steps.rs`.
### EN
**Added:**
- **Dedicated Build Engine (`src/core/build/engine.rs`)** — decoupled the build orchestration logic completely from the CLI front-end wrapper in `src/cli/build.rs` to a reusable, decoupled core build engine.
- **Polymorphic Language Model (`Language` trait)** — introduced the abstract `Language` trait (`src/core/build/language/mod.rs`). File scanning, compiler resolution, and flags handling are now encapsulated in dedicated language modules for C, C++ (including Qt code generation), LLVM IR, and ASM (GAS, NASM, FASM, MASM).
- **Polymorphic Compilation Dispatch (`Builder` trait)** — introduced the `Builder` trait to generalize builder invocations (`src/core/build/builder/mod.rs`). Consolidated GCC/Clang logic into `builder/cc_common.rs` and Microsoft Visual C++ logic into `builder/msvc/`.
- **Per-Language Configuration overrides (`[build.<lang>]`)** — introduced support for configuring language-specific compiler, standard, and flags (e.g. `[build.c]`, `[build.cpp]`, `[build.asm]`) independently in `dcr.toml`.
- **Automatic Workspace Dependency Injection** — during workspace builds, include/lib paths of dependent workspace members (including their source headers, local `include/` folders, and build target `target/include` / `target/lib` folders) are automatically resolved and injected.
- **`BuildReporter` Event System** — decoupled build orchestration output into a structured event-driven reporter model (`src/core/build/report.rs`), making DCR suitable for library embedding and IDE integrations without stderr capturing.
- **Build Cancellation Support** — introduced thread-safe cancellation tokens (`Arc<AtomicBool>`) allowing clients to safely abort compile runs mid-execution.
- **TOML Formatting & Custom Keys Preservation** — migrated the config editor to `toml_edit`, preserving all unknown/user-defined TOML keys, structures, and comments during file write operations (e.g., in `dcr add`).
- **Path Dependencies Target Include Resolution** — local path dependencies configured via tables now correctly expose headers built and packaged into their `target/include` folder to consumer packages.
- **Modular Integration Test Suite** — refactored the monolith `tests/cli_basic.rs` file into clean, specialized integration tests: `cli_build.rs`, `cli_deps.rs`, `cli_lint.rs`, `cli_new.rs`, `cli_qt.rs`, `cli_test.rs`, `cli_workspace.rs`.
**Changed:**
- **Consolidated Linking and Archiving** — artifact generation (linking executables/shared libraries and archiving static libraries) consolidated into a single `src/core/build/builder/artifact.rs` module.
- **Workspace-Aware member execution** — `dcr run` executed at the workspace root of a `workspace_only` project now triggers the member build inside the workspace context using the `--workspace` parameter, preventing standalone build issues.
- **Elimination of Global State** — removed global variables and states from the build core, encapsulating build logic inside isolated `BuildContext` structs for thread safety.
- **Build Cache Separation** — relocated mtime tracking, incremental caching, and header-dependency checking logic to `src/core/build/cache.rs`.
- **Modularized Pre-build Steps** — decoupled generator scripts and pre-build commands parsing into `src/core/build/steps.rs`.

# DCR TODO.md
Priority list of tasks to turn DCR into a true Cargo killer for C/C++ developers.
**Legend:** `[ ]` — not implemented | `[-]` — partially implemented | `[x]` — implemented
## 🔥 High Priority
- [ ] **CLI Output Refactoring & Cleanup**
- [ ] Move all terminal strings to a dedicated module (`src/ui/messages.rs`)
- [ ] Standardize logging formats (`error:`, `warning:`, `status:`)
- [x] Add build execution time statistics to the final output (e.g., `Finished in 4.23s`)
- [ ] **Internationalization (i18n) / Localization**
- [ ] Integrate a lightweight localization engine (`fluent` or `gettext` pure-Rust port)
- [ ] Create initial translation catalogs (`en.ftl`, `ru.ftl`)
- [x] **Self-Update Stability Validation**
- [x] Self-update implemented via `self-replace` + `ureq` in `flag_update.rs`
- [-] **Freestanding / Embedded Automation**
- *`-ffreestanding` injected at compile time, `-nostdlib -static` at link time for bare-metal targets or `build.freestanding = true`. Config option `build.freestanding` (bool) added.*
- [ ] **Conan and vcpkg integration** Automatic download, installation and linking of packages
## ✅ Medium Priority
- [ ] **Static analysis** (`dcr check`)
Integration with clang-tidy, cppcheck, include-what-you-use
- [-] **Linter + Formatter** (`dcr fmt`, `dcr lint`)
*`dcr fmt` (clang-format) implemented; `dcr lint` does not exist yet*
- [ ] **Hot reload / Live reload** for applications (raylib, SFML, SDL, etc.)
- [-] **Workspaces improvements** Per-member include directories, selective builds, better dependency graph
*Basic workspaces with dep ordering + topological sort work; advanced features missing*
- [-] **Build-time code generation** Support for protobuf, flatbuffers, Qt moc, custom generators
*Generic `build.steps` machinery + Qt toolchain (uic/moc/rcc) work; no dedicated protobuf/flatbuffers generators*
- [-] **dcr publish + official package registry** *Registry consumption (fetch, resolve, link) works; `dcr publish` command / local packing missing*
## 📌 Low Priority / Nice to Have
- [ ] Support for Meson and Ninja as alternative backends
- [ ] Dockerfile generation (`dcr docker init`)
- [ ] First-class Windows MSVC support (currently works but rough)
- [ ] Documentation generation (`dcr doc`)
- [ ] Sanitizers integration (`dcr sanitize`)
- [ ] Benchmarks and comparison with CMake/Meson
- [ ] C++20 modules support (when it becomes stable)
## 🧠 Future Ideas
- Official DCR package registry (dcrhub)
- GUI wrapper (dcr-gui)
- Plugin system
- Toolchain manager (like rustup)
- Zig as alternative compiler
- deb/rpm/flatpak/AppImage packaging support
---
**Currently in progress:**
- UI/UX terminal output unification and benchmarking metrics.
**Completed in recent releases:**
- Extreme binary size optimization (-50% weight reduction via `ureq` + `native-certs`)
- Complete removal of `git2` and `openssl` in favor of system Git execution
- Workspaces & Cross-compilation (`--target <triple>`)
- IDE config generation (VS Code, CLion, compile_commands.json)
- EFI support & Linker script support (`build.ldscript`)
- Mixed C/C++/ASM compilation with custom `std::thread::scope` work-stealing engine

# Changelog
## 0.9.1 (2026-09-13)
* **`pkg-config` dependencies** — declare `fmt = { pkg-config = "fmt" }` or multiple package names in `[dependencies]`; DCR applies `.pc` compiler/linker flags and records the resolved package in `dcr.lock`.
* **`dcr add` support for `pkg-config`** — easily add system package dependencies with `dcr add fmt pkg-config:fmt` or `dcr add openssl pkg:openssl,libcrypto`.
* **`dcr tree` & IDE integration** — `pkg-config` packages are marked in `dcr tree` and resolved into compiler flags in `dcr gen` (`compile_commands.json`).
* **Fixed `dcr new` in non-ASCII / spaced paths** — initializing projects from folders with non-ASCII characters or spaces no longer fails validation.
## 0.9.0 (2026-08-31)
* **Download mirrors in `dcrup`** — `--mirror auto|cf|gh|sf|ya` and `DCRUP_MIRROR`.
Default `auto` tries **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
* **Complete Path/Git dependencies** — DCR packages from `path` and `git` are built before their consumer. Git sources are cached in `~/.dcr/git`, support `branch`/`tag`/`rev`, and record the exact commit in `dcr.lock`.
* **Build and prebuild modes** — `path` and `git` dependencies can build a DCR package from `dcr.toml` or link existing `include`/`lib`/`libs` artifacts; `mode = "build"` / `"prebuild"` selects explicitly when both forms are present.
* **Prebuilt dependency examples** — documentation now shows the `dcr-math-lib` Git repository and recommended build/prebuilt layouts for both `git` and `path`.
* **Transitive dependency builds and cycle reporting** — DCR recursively builds DCR packages and reports a clear dependency chain for cycles.
* **Bare path arguments for `dcr add`** — `dcr add mylib ../mylib` now works in addition to the explicit `path:` form.
* **Removed `install.sh` / `install.ps1` / `install_bsd.sh`** — superseded by `dcrup`.
## 0.8.5 (2026-08-08)
* **`package.dcr-version`** — optional CLI version pin in `dcr.toml`.
`dcr new` / `dcr init` write the current version. On config load:
* missing / empty pin → warn "add dcr-version";
* dcr older than pin → warn "update dcr";
* dcr newer than pin → warn "check changelog, update pin";
* equal → silent.
Commands do not fail, warning only (once per path per process).
## 0.8.4 (2026-08-04)
**Added:**
* **`.dcr/` directory** — shared machine-readable build facts for IDE integrations:
* `.dcr/compile_commands.json`
* `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
* `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
* `.dcr/ide/` (placeholder for IDE lock files)
* **`dcr gen project-info`** — `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; absolute/canonical paths.
* **`dcr build --print-artifact-path`** — one absolute artifact path line on stdout after a successful build.
* **`dcr gen … --quiet` / `-q`** — suppress human success logs for gen subcommands.
* **`.clangd`** — created on first gen with `CompilationDatabase: .dcr` (`# managed by dcr gen`); custom `.clangd` is not overwritten.
* **Helpers** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` via `platform::*`.
* **`dcr new` / `dcr init`** — add `.dcr/` to `.gitignore`.
**Changed (breaking):**
* **`compile_commands.json` moved** from project root to **`.dcr/compile_commands.json`**.\
clangd discovers it via `.clangd` / `--compile-commands-dir=.dcr`.\
CLion and VSCode generators updated accordingly.
* **Atomic write** for compile_commands (tmp + rename).
* **`gen vscode` / `gen clion` launch/run** — use the same artifact path resolver as `project-info` / `build-info.json`.
**Fixed:**
* Launch configs no longer hardcode `target/\<profile>/\<name>` without the Linux triple segment.
* Symlink/mount roots: best-effort canonicalize for root and compile database paths.
## 0.8.3 (2026-08-03)
### Added
* **`dcr run -- \<args>...`** — cargo-style argument forwarding after a bare `--`\
(`dcr run --release -- --test_help`). Applies to direct binary runs and `[run].cmd`.
* **Tests** — host target section `ldflags` without CLI `--target`; run-arg forwarding; `split_double_dash` unit tests.
### Changed
* **Native builds resolve the host triple** — without `--target` / package `build.target`, host sections such as\
`[build.x86_64-unknown-linux-gnu]` apply again (`cflags` / `ldflags` / toolchain).\
Previously the target was empty and those sections were ignored while artifacts already used the host triple path.
* **Empty target** — no more `Unknown target ''` warning.
* **`dcr run --help` / man `dcr-run`** — document `--` forwarding.
### Fixed
* **Native artifact paths on Windows and macOS** — without an explicit `--target` / `build.target`, artifacts use `target/\<profile>`, so `dcr run` and flat-bin find the build output.
* Target-specific `ldflags` missing on native host builds (e.g. micro-lang + `libsct-elf`).
* Spurious empty-target warning.
## 0.8.2 (2026-07-22)
### Added
* **Compile progress `[N/M]`** — live TTY status line (`compile pkg v0.1.0 [12/41]`) so long mono-package builds do not look hung.
* **DCR status style** — fixed-width verbs: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run`.
* **Cargo feature `archive`** — optional FAT packing via `fatfs` (`cargo build --features archive`). Release CI builds with the feature; without it `[archive]` fails with a clear message.
* **Tests** — `flat_bin_nasm_build`, package `build.target` without CLI `--target`, stricter workspace `clean --all`.
* **CI expansion** — unit + integration on Linux/macOS/Windows, archive feature job, rust-cache, clippy default + all-features (see `.github/workflows/ci.yml`).
### Changed
* **No forced host triple from CLI** — without `--target`, package/member `build.target` is honored (bare-metal / ISO `post_steps` paths).
* **Relative include/lib flags** (`-I`, `-i`, `-isystem`, `-idirafter`, `-L`, `-T`) absolutized against the package root under workspace builds.
* **`dcr clean --all`** — no spam for members without a local `target/` (shared root `target/`).
* **`error` / `warn`** — red / yellow on stderr; CLI fully English (`Hint:`).
* **Help / man** — list `add`, `lint`, `setup`; unknown command exits with code 1.
* **Tool NotFound** — `linker not found: ld.lld …` / `{tool} not found …` instead of raw `os error 2`.
## 0.8.1 (2026-07-20)
### Added
* **`build.kind = "flat-bin"`** — raw binary (default `.bin`) for OS-dev payloads:
* **NASM** — `-f bin` → `\<stem>.bin`
* **FASM** — direct output (`format binary` in source)
* **GAS / MASM / LLC** — object → `objcopy -O binary` → `\<stem>.bin`
* **C/C++** — objects → freestanding link → `objcopy -O binary` → `\<name>.bin`
* Requires `llvm-objcopy` / `objcopy` / `gobjcopy` except for NASM/FASM direct emit
* **`[archive]` section** — FAT12/16/32 disk images after build (`output`, `format`, `size`, `offset`, `label`, `bootsector`, `layout`). From 0.8.2 requires feature `archive`.
* **Single-file `build.roots`** — a root may be a single source or header file, not only a directory.
### Changed
* **`--force`** also re-runs `build.steps` and `build.post_steps`.
* **`dcr run` on workspace-only root** — if `[run].cmd` is set, run that after build; otherwise delegate to a workspace member.
## 0.8.0 (2026-07-18)
### Added
* **Dedicated Build Engine (`src/core/build/engine.rs`)** — decoupled the build orchestration logic completely from the CLI front-end wrapper in `src/cli/build.rs` to a reusable, decoupled core build engine.
* **Polymorphic Language Model (`Language` trait)** — introduced the abstract `Language` trait (`src/core/build/language/mod.rs`). File scanning, compiler resolution, and flags handling are now encapsulated in dedicated language modules for C, C++ (including Qt code generation), LLVM IR, and ASM (GAS, NASM, FASM, MASM).
* **Polymorphic Compilation Dispatch (`Builder` trait)** — introduced the `Builder` trait to generalize builder invocations (`src/core/build/builder/mod.rs`). Consolidated GCC/Clang logic into `builder/cc_common.rs` and Microsoft Visual C++ logic into `builder/msvc/`.
* **Per-Language Configuration overrides (`[build.\<lang>]`)** — introduced support for configuring language-specific compiler, standard, and flags (e.g. `[build.c]`, `[build.cxx]`, `[build.asm]`) independently in `dcr.toml`.
* **Automatic Workspace Dependency Injection** — during workspace builds, include/lib paths of dependent workspace members (including their source headers, local `include/` folders, and build target `target/include` / `target/lib` folders) are automatically resolved and injected.
* **`BuildReporter` Event System** — decoupled build orchestration output into a structured event-driven reporter model (`src/core/build/report.rs`), making DCR suitable for library embedding and IDE integrations without stderr capturing.
* **Build Cancellation Support** — introduced thread-safe cancellation tokens (`Arc\<AtomicBool>`) allowing clients to safely abort compile runs mid-execution.
* **TOML Formatting & Custom Keys Preservation** — migrated the config editor to `toml_edit`, preserving all unknown/user-defined TOML keys, structures, and comments during file write operations (e.g., in `dcr add`).
* **Path Dependencies Target Include Resolution** — local path dependencies configured via tables now correctly expose headers built and packaged into their `target/include` folder to consumer packages.
* **Modular Integration Test Suite** — refactored the monolith `tests/cli_basic.rs` file into clean, specialized integration tests: `cli_build.rs`, `cli_deps.rs`, `cli_lint.rs`, `cli_new.rs`, `cli_qt.rs`, `cli_test.rs`, `cli_workspace.rs`.
### Changed
* **Consolidated Linking and Archiving** — artifact generation (linking executables/shared libraries and archiving static libraries) consolidated into a single `src/core/build/builder/artifact.rs` module.
* **Workspace-Aware member execution** — `dcr run` executed at the workspace root of a `workspace_only` project now triggers the member build inside the workspace context using the `--workspace` parameter, preventing standalone build issues.
* **Elimination of Global State** — removed global variables and states from the build core, encapsulating build logic inside isolated `BuildContext` structs for thread safety.
* **Build Cache Separation** — relocated mtime tracking, incremental caching, and header-dependency checking logic to `src/core/build/cache.rs`.
* **Modularized Pre-build Steps** — decoupled generator scripts and pre-build commands parsing into `src/core/build/steps.rs`.
## 0.7.4 (2026-06-17)
### Added
* **Native Qt support** — automatic meta-object handling (MOC, UIC, RCC) added when `build.qt = true` is set in `dcr.toml`.
* **`dcr lint` command** — C/C++ static analysis via `clang-tidy`. Supports `--fix` for automatic fixes. Respects `build.roots` and `build.src_disable` from config.
* **Three new assembler backends**:
* **MASM** (`compiler = "ml"` / `"ml64"`) — Microsoft Macro Assembler.
* **FASM** (`compiler = "fasm"`) — Flat Assembler.
* **LLVM IR** (`compiler = "llc"`) — compiles `.ll` files via `llc -filetype=obj`.
* **Shared ASM pipeline** — linking and archiving logic consolidated into `core/builder/asm.rs`. Adding a new assembler backend now takes ~30 lines.
* **Filesystem utilities** — `to_hex()` and `home_dir()` extracted to `utils/fs.rs`.
* **Build utilities** — `normalize_target()`, `normalize_kind()`, `normalize_platform()`, `default_profile_flags()` extracted to `utils/build.rs`.
* **Backend helpers** — `asm_lang_flag()`, `source_extensions()`, `elapsed_secs()` added to `core/builder/common.rs`.
* **Full Bare-Metal / Freestanding Automation** — introduced the `build.freestanding = true` configuration option. When enabled (or when a bare-metal target is detected), DCR automatically injects `-ffreestanding` during compilation and both `-nostdlib` and `-static` during linking.
* **Artifact Optimization (LTO & Strip)** — added `build.lto` (auto-injects `-flto` for compiler and linker) and `build.strip` (automatically strips debug symbols via linker `-s` flag) options to `dcr.toml`.
* **Compilation Thread Control** — added the `build.codegen-units` option to strictly limit the maximum number of parallel jobs utilized by the custom `parallel_build` worker pool.
* **Panic Behavior Management** — added `build.panic = "abort"` support. For C++ targets, it automatically strips exception handling and unwind tables via `-fno-exceptions`, `-fno-unwind-tables`, and `-fno-asynchronous-unwind-tables`.
### Changed
* **Intelligent Default Flags Generation** — automated injection of fallback optimization (`-O3`/`-O0`), debug (`-g`), and warning (`-Wall -Wextra`) flags is now suppressed for bare-metal and freestanding builds if `build.cflags` are overridden.
* **Centralized Bare-Metal Detection** — relocated the `is_bare_metal_target` helper to common build utilities (`src/utils/build.rs`) for unified access across the building core.
* **Architectural Refactoring**:
* Renamed `src/config.rs` to `src/templates.rs`.
* Started consolidation of configuration and build orchestration logic.
## 0.7.3 (2026-06-13)

* **`--vcs` option for `new` and `init` commands** — introduced explicit version control system selection via `--vcs \<git|none>`.
* **Git metadata integration in `--version`** — the CLI now appends the current short commit hash and a `-dirty` suffix if there are uncommitted changes in the DCR repository.
* **Automatic `.gitignore` generation** — Git repository initialization now automatically writes a `.gitignore` file excluding the `/target` directory.
* **Nested repository prevention** — automatic Git initialization is now skipped if `dcr new` or `dcr init` is executed inside an already existing Git repository.
* **VCS verification tests** — added `new_vcs_options_work` and `init_vcs_options_work` integration tests to ensure reliable repository behavior.
### Changed
* **Complete removal of `git2` dependency** — all Git actions (dependency fetching, VCS setup, status checks) are now delegated to the system `git` executable via `Command`. This simplifies compilation and drops the need for `vendored` and `openssl` features.
* **Migrated from `reqwest` to `ureq`** — replaced the heavy `reqwest` crate in `flag_update.rs` with the lightweight synchronous `ureq 2.10` client, reducing overhead and the final binary size.
## 0.7.2 (2026-06-07)
### Added
* `default_target_triple()` now respects `target_env` — Linux (gnu/musl) and Windows (msvc/gnu) use the correct environment instead of hardcoded values.
### Fixed
* **macOS Apple Silicon builds failed with `_main` undefined** — `--target=` is now passed to ldflags, not just cflags. `default_target_triple()` uses `std::env::consts::ARCH` on macOS instead of hardcoded `x86_64`.
* **GitHub Stars and GPL-3.0 badges not rendering in README** — badge block converted to pure HTML.
### Changed
* Default target resolution extracted into shared `default_target_triple()` — removed duplication across build, run, clean.
## 0.7.1 (2026-06-02)
### Added
* **`--help` for all commands** — `dcr build --help`, `dcr run --help`, `dcr new --help`,
`dcr init --help`, `dcr clean --help`, `dcr add --help`, `dcr fmt --help`,
`dcr setup --help`, `dcr tree --help`, `dcr gen --help`, `dcr --update --help`,
`dcr test --help`. All output uses styled headers (green) and usage lines (cyan).
* **Man pages** — 12 troff pages in `man/man1/`: `dcr.1`, `dcr-build.1`,
`dcr-run.1`, `dcr-new.1`, `dcr-init.1`, `dcr-clean.1`, `dcr-add.1`, `dcr-test.1`,
`dcr-gen.1`, `dcr-fmt.1`, `dcr-tree.1`, `dcr-setup.1`.
* **Man pages in all packaging** — install.sh, install_bsd.sh, AUR PKGBUILD,
Debian (cargo-deb), RPM (cargo-generate-rpm), Nix (postInstall), Homebrew
(resource), Snap, GitHub Release assets.
* **Project name validation** — `dcr init` and `dcr new` now validate names before
creating files. Only ASCII letters, digits, `_` and `-` are allowed.
* **`documentation` and `homepage` fields** — added to `Cargo.toml`.
* **Release profile optimizations** — `opt-level = "z"`, LTO, `codegen-units = 1`,
`panic = "abort"`, `strip = true` for smaller binaries.
* **Linux i686, armv7, riscv64 targets** — added to release workflow and install scripts.
* **Linux musl i686, armv7 targets** — cross-compiled via zigbuild in CI.
* **AUR packages** — `dcr-dev`, `dcr-dev-bin` publishing workflow.
* **Snap publishing** — automated Snapcraft publishing in CI.
* **Snap badge** — in README.
### Changed
* **`validate_package_name` made public** — callable from CLI commands.
* **README platform table** — reorganized: libc variants as separate OS rows,
removed extra columns. Linux architecture list updated.
* **`gen.rs` no-args output** — now uses styled output instead of raw `eprintln!`.
* **`tree.rs`, `fmt.rs`, and `setup.rs`** — now accept arguments for `--help`.
* **README install commands** — `| bash` → `| sh` for POSIX compatibility.
### Fixed
* **`dcr new \<invalid-name>` creates directory then fails** — validation now
happens before any file operations.
* **`dcr init` on invalid directory name** — same fix.
* **Man pages missing in installed packages** — now shipped in all formats.
* **Windows drive letter false positive** — in dependency file parser.
* **CRLF (`\r\n`) breaks dependency parser** — now handles mixed line endings.
* **Newline after backslash not consumed** — in `parse_d_file` escape handling.
## 0.7.0 (2026-06-01)
### Added
* **OpenBSD and NetBSD target support** — full platform routing with dynamic target triples using `std::env::consts::ARCH` and `std::env::consts::OS`. Affects `build`, `run`, `clean` commands and the platform module.
* **`src/platform/bsd.rs`** — new BSD platform module (shared by FreeBSD, OpenBSD, NetBSD) providing `bin_path`, `lib_path`, `elf_path`, `efi_path`, `shared_lib_path`.
* **`build.out_dir` config option** — custom output directory that overrides the default `target/\<triple>/\<profile>` path for final artifacts. Supported in `build`, `run`, and config validation.
* **`dcr fmt` command** — new CLI command that formats all C/C++ source files (`*.c`, `*.cpp`, `*.h`, `*.hpp`) in `src/` and `tests/` using `clang-format`.
* **Incremental linking** — `needs_link()` in `common.rs` checks if any object file is newer than the linked output, skipping unnecessary relinking. Implemented for all backends (`unix_cc`, `msvc`, `gas`, `nasm`).
* **`build.kind = "none"` and `"custom"`** — two new project kinds for special build scenarios that don't produce standard artifacts.
* **`install_bsd.sh`** — POSIX-compliant installation script for BSD systems (FreeBSD, OpenBSD, NetBSD) with binary download and source build modes.
* **Linux ARM64 support in `install.sh`** — added `Linux:aarch64|Linux:arm64` target detection for pre-built binary downloads.
* **BSD OS detection in `install.sh`** — detects FreeBSD, OpenBSD, NetBSD and determines target triple.
* **`rust-toolchain.toml`** — explicit toolchain pinning to `stable` channel.
* **Integration tests** — `build_with_target_config` (verifies `build.target = "linux"`) and `build_with_out_dir` (validates custom output directory).
* **`get_build_string_with_profile` made `pub`** — so `run.rs` can determine custom output directory configuration.
### Changed
* **`build.target` semantics changed** — now strictly contains a target triple (e.g., `x86_64-unknown-linux-gnu`) or short name (`linux`, `macos`, `windows`). No longer used as custom output directory — this functionality moved to `build.out_dir`.
* **`build.standard` made optional** — changed from `String` to `Option\<String>`. Validation only enforces non-empty for non-ASM languages. Skipped in `dcr.toml` output if empty.
* **`dcr run` with `out_dir`** — now determines target directory respecting `build.out_dir` via `get_build_string_with_profile()` from `build.rs`.
* **`collect_sources()` returns empty vector** instead of error when no sources are found, allowing `kind = "none"` or `kind = "custom"` projects with no source files.
* **CI/CD release workflow refactored** — `git2` made target-specific (no vendored-openssl on Windows), Zig-based cross-compilation for non-x86_64 Linux targets, Arch Linux package version cleanup (dashes → dots), `gmake` symlink for NetBSD.
* **README compatibility table** — FreeBSD, OpenBSD, NetBSD build/run status upgraded from "community/best-effort" to "officially supported".
* **Documentation updated** — `build-section.md` describes new `build.target` and `build.out_dir` fields. `target-directory.md` rewritten to clarify the distinction.
### Fixed
* **stdout/stderr not inherited in `dcr run`** — child process output was captured and manually printed, breaking interactive programs. Fixed by switching to `Command::status()`.
* **Race condition in release CI** — matrix build jobs could upload assets to a release that didn't exist yet. Fixed by adding a dedicated `create-release` job.
* **Release GHA — stable toolchain override** — fixed Rust toolchain override issues in CI.
* **Arch Linux package version sanitization** — version strings with dashes (e.g., `0.7.0-dev`) are invalid for `pkgver`. Fixed by replacing dashes with dots.
* **GPG permissions after Docker** — Docker operations changed GPG directory ownership. Fixed by running `chown` after Docker commands.
* **RPM artifact paths** — RPM artifacts were placed in `rpm/x86_64/` instead of `fedora/x86_64/`. Fixed in Dexoron Packages Index workflow.
* **JSON parsing reliability in `install.sh`** — added `jq` as primary parser with `python3` fallback for dev channel release lookup.
### Removed
* **`format_roots()` helper function** — removed from `common.rs`. Was only used by the old error handling path in `collect_sources()`.
* **Per-distribution artifact download steps** — three separate `actions/download-artifact` steps replaced with unified `gh release download --clobber`.

# Build Commands
## `dcr build`
Builds the project according to `dcr.toml`.
```bash
dcr build # debug profile
dcr build --release # release build
dcr build --debug # explicit debug
dcr build --target aarch64-unknown-linux-gnu
dcr build --force # full rebuild (also re-runs build.steps / post_steps)
dcr build --clean # clean + build
dcr build --verbose # show compilation commands
dcr build --workspace pkg-a # build specific workspace package
```
Artifacts: `target/\<triple>/\<profile>/\<binary-name>` (Linux with explicit target).
With `[archive]` in `dcr.toml`, a FAT disk image is packed after a successful build.
## `dcr run`
Builds (if sources are newer than artifacts) and runs the binary.
```bash
dcr run
dcr run --release
dcr run --force # force rebuild then run
```
On a **workspace-only** root: if `[run].cmd` is set, that command is used after build; otherwise DCR delegates to a workspace member.
## `dcr clean`
Removes `target/` directory (or `target/\<target>/\<profile>`).
```bash
dcr clean
dcr clean --release # target/release/ only
dcr clean --target windows # target/x86_64-pc-windows-msvc/
dcr clean --all # clean all workspace packages

# Dependency Commands
## `dcr add \<name> [source]`
Adds a dependency to `dcr.toml`.
```bash
dcr add fmt # registry lookup
dcr add mylib ../path/to/lib # path as source
dcr add mylib path:./lib # explicit path prefix
dcr add mylib git:https://github.com/user/repo # explicit git prefix
dcr add mylib github:user/repo # GitHub shorthand
dcr add mylib gitlab:user/repo # GitLab shorthand
dcr add fmt pkg-config:fmt # system package via pkg-config
dcr add openssl pkg:openssl,libcrypto # multiple pkg-config packages
```
Source prefixes:
* `path:` — local path
* `git:` — generic git URL
* `github:` — expands to `https://github.com/\<user>/\<repo>`
* `gitlab:` — expands to `https://gitlab.com/\<user>/\<repo>`
* `pkg-config:` / `pkg:` — one or more packages resolved by `pkg-config`
* `http://` / `https://` / `git@` — full URL
Flags:
* `--branch \<name>` — git branch
* `--tag \<name>` — git tag
* `--rev \<hash>` — git commit
If source is omitted — DCR searches connected registries. A bare relative or absolute path is accepted as a path dependency.
For `pkg-config` dependencies, the referenced packages must already be installed
and provide `.pc` files. DCR invokes `pkg-config` during the build (using
`PATH` and `PKG_CONFIG_PATH`) and forwards the returned compiler and linker
flags; it does not download or build these packages.
## `dcr tree`
Displays the project dependency tree.
```bash
dcr tree
```
Example output:
```
my-app v0.1.0
├── fmt (registry)
│ └── spdlog (registry)
└── catch2 (registry)
```
For path dependencies, recursively shows their own dependencies (from their `dcr.toml`).

# Project Commands
## `dcr new \<name>`
Creates a new project with a standard structure and `dcr.toml`. The `name` argument is required.
Only ASCII letters, digits, underscores `_` and hyphens `-` are allowed in the project name.
```bash
dcr new my-app
dcr new my-app --vcs none
```
Flags:
* `--vcs \<git|none>` — Initialize version control system (defaults to `git` if available, or `none`).
Generates:
* `dcr.toml` with basic fields
* `src/main.c` with a `main` template
## `dcr init`
Initializes a DCR project in the current (empty) directory.
```bash
dcr init
dcr init --vcs none
```
Flags:
* `--vcs \<git|none>` — Initialize version control system (defaults to `git` if available, or `none`).
The project name is taken from the current directory name. The directory name must follow the same naming rules as `dcr new`.

# Quality Commands
## `dcr test`
Runs tests.
```bash
dcr test # debug profile
dcr test --release # release profile
dcr test --debug # explicit debug
dcr test --help # detailed help
```
Before first use, initialize tests:
```bash
dcr test --init
```
This creates `tests/dcr_test.h` (framework) and `tests/test.c` (template).
What `dcr test` does:
1. Builds the project
2. Collects `tests/*.c` files (`.c` only, not `.cpp`)
3. Compiles and links each test file
4. Runs each test binary
5. Prints summary: TOTAL, PASS, SKIP, FAIL
6. Returns non-zero exit code on any FAIL
## `dcr fmt`
Formats C/C++ source files using `clang-format`.
```bash
dcr fmt
```
Processes: `src/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}` and `tests/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}`.
Uses `.clang-format` at the project root (if present), otherwise default clang-format style.
## `dcr lint`
Runs `clang-tidy` on C/C++ source files for static analysis.
```bash
dcr lint # show diagnostics
dcr lint --fix # apply fixes automatically
dcr lint --help # detailed help
```
Processes: `src/**/*.{c,cpp,cxx,cc}` and `tests/**/*.{c,cpp,cxx,cc}`.
Without `--fix`, clang-tidy reports warnings and errors without modifying files.
With `--fix`, clang-tidy applies automatic suggestions in place.

# FAQ
## Registry not found
```
error: registry not found
```
**Solution:** Make sure `~/.dcr/config.toml` exists:
```toml
[registry.default]
url = "https://index.dcr.pm"
priority = 1
```
And check `DCR_INDEX_PATH`:
```bash
echo $DCR_INDEX_PATH
```
## Compiler not found
```
error: compiler not found
```
**Solution:** Ensure a compiler is installed and available in PATH.
```bash
which gcc
which clang
```
Or specify explicitly via `[toolchain]` in `dcr.toml`.
## Ctrl+C during build
DCR handles SIGINT: interrupts the current compilation and exits with non-zero code.
## How to create a library?
See [Library Recipe](/docs/recipes/library-project).
## How to cross-compile to Windows?
See [Cross-Compile Recipe](/docs/recipes/cross-to-windows).
## How to create a multi-package project?
See [Workspace Recipe](/docs/recipes/multi-package-workspace).
## Bootloader / pure NASM OS image
Use `kind = "flat-bin"` (NASM `-f bin`) and optional `[archive]` for a FAT disk image.
See [OS-dev recipe](/docs/recipes/os-flat-bin-archive).
## How do I choose a download mirror?
`dcrup install` uses `--mirror auto` by default and tries **cf → gh → sf → ya**.
```bash
dcrup install stable --mirror cf
export DCRUP_MIRROR=ya
```
## Lock file
`dcr.lock` is created during builds (`dcr build`) when registry dependencies are present. To force an update — delete `dcr.lock` and run `dcr build`.

# Installation
## dcrup (recommended)
Install and switch DCR versions (stable / dev / night, pin `0.8.2`, optional build from source).
### Linux / macOS / BSD / Windows (bash)
```sh
curl -fsSL https://sh.dcr-tool.ru | sh -s -- self-install
export PATH="$HOME/.dcr/bin:$PATH"
dcrup install stable
```
Non-interactive install of DCR in one shot:
```sh
curl -fsSL https://sh.dcr-tool.ru | sh -s -- install stable
export PATH="$HOME/.dcr/bin:$PATH"
```
### Windows (PowerShell)
```powershell
irm https://ps1.dcr-tool.ru | iex
# or download then run:
# irm https://ps1.dcr-tool.ru -OutFile dcrup.ps1
# powershell -File .\dcrup.ps1 self-install
# $env:Path += ";$env:USERPROFILE\.dcr\bin"
dcrup install stable
```
Optional cmd bootstrap (if you prefer `curl` of the cmd shim):
```bat
curl -fsSL -o dcrup.cmd https://cmd.dcr-tool.ru
```
After `self-install`, the command is **`dcrup`** (no `.sh` / `.ps1`): shims live in `~/.dcr/bin` (Unix) or `%USERPROFILE%\.dcr\bin` (Windows `dcrup.cmd`).
### Common dcrup commands
```sh
dcrup install stable # latest stable prebuilt (auto: cf → gh → sf → ya)
dcrup install 0.8.2 # pin → 0.8.2@stable
dcrup install 0.8.2@dev
dcrup install stable --libc musl # Linux: musl asset (default: gnu)
dcrup install stable --mirror cf # CloudFlare CDN
dcrup install stable --mirror ya # Yandex CDN (RU fallback)
dcrup install stable --build # cargo build --features archive
dcrup install night # always build from branch dev HEAD
dcrup default 0.8.2
dcrup update
dcrup list
dcrup show
dcrup which
```
Layout: `~/.dcr/toolchains/\<id>/dcr` and `~/.dcr/bin/dcr` → active version.
### Download mirrors
Prebuilt installs try **cf → gh → sf → ya** unless you pin a host.
| Code | URL | Notes |
| ---- | ------------------------------------------------------------------------------------------------------------ | -------------------------- |
| `cf` | `https://cdn-global.dcr-tool.ru/\<tag>/\<asset>` | CloudFlare CDN (worldwide) |
| `gh` | `https://github.com/dexoron/dcr/releases/download/\<tag>/\<asset>` | GitHub Releases |
| `sf` | `https://sourceforge.net/projects/dcr-tool/files/\<tag>/\<asset>/download` | SourceForge |
| `ya` | `https://cdn-ru.dcr-tool.ru/\<tag>/\<asset>` | Yandex CDN (RU fallback) |
```sh
dcrup install stable --mirror auto # default
export DCRUP_MIRROR=cf # persist for this shell
```
---
## Arch Linux (AUR)
```sh
yay -S dcr
```
## macOS / Linux (Homebrew)
```sh
brew tap dexoron/dexoron
brew install dcr
```
## Snap (Linux)
```sh
sudo snap install dcrup
```
> If classic Snap Store publishing is unavailable, install the `.snap` from [GitHub Releases](https://github.com/dexoron/dcr/releases/latest) with `--dangerous`.
## Nix (flake)
```sh
nix run github:dexoron/dcr
nix profile install github:dexoron/dcr
```
## Cargo (crates.io)
```sh
cargo install dcr
```
Note: crates.io builds may omit optional features. For FAT disk images (`[archive]`), prefer release binaries or:
```sh
cargo install dcr --features archive
```
## From source
```sh
git clone https://github.com/dexoron/dcr.git
cd dcr
cargo build --release --features archive
ln -sf "$PWD/target/release/dcr" ~/.local/bin/dcr
# or manage versions with dcrup install night / --build
```
## Post-install
```bash
dcr --version
dcrup show # if installed via dcrup
```

# IDE Integration
## VS Code
Install the recommended [DCR extension by Dexoron-Labs](https://marketplace.visualstudio.com/items?itemName=Dexoron-Labs.dcr). Do not install Microsoft C/C++ extensions for DCR projects: DCR uses `clangd`. MS C/C++ is acceptable only when you need its debugger.
Recommended companion extensions:
* [Even Better TOML](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml)
* [CodeLLDB](https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb), or MS C/C++ for debugger support only
```bash
dcr gen vscode
```
Generates in `.vscode/`:
| File | Purpose |
| ----------------- | -------------------------------------------- |
| `tasks.json` | `build` task (dcr build) |
| `launch.json` | Debug launch configuration |
| `settings.json` | clangd/IntelliSense: include paths, standard |
| `extensions.json` | Recommends vscode-clangd, vscode-lldb |
## CLion
```bash
dcr gen clion
```
Generates in `.idea/`:
| File | Purpose |
| ------------------------------------------------ | ----------------------------------------- |
| `externalTools.xml` | Build, Run, Clean, Test as external tools |
| `customTargets.xml` | Custom build targets |
| `misc.xml` | C/C++ project settings |
| `runConfigurations/\<name>.xml` | Per-binary run configurations |
## compile_commands.json
```bash
dcr gen compile-commands
```
Generates `compile_commands.json` at project root. Standard format for clangd, C/C++ IntelliSense, static analyzers.
## project-info
```bash
dcr gen project-info
```
Outputs JSON array with project metadata (see [gen-commands](/docs/commands/gen-commands)).

# Library Project
Creating a static library and using it in another project.
## Step 1: Create the library
```bash
dcr new my-lib
cd my-lib
```
`dcr.toml`:
```toml
[package]
name = "my-lib"
version = "0.1.0"
type = "none"
[build]
language = "c"
standard = "c11"
kind = "staticlib"
```
`src/my_lib.h`:
```c
#ifndef MY_LIB_H
#define MY_LIB_H
int add(int a, int b);
#endif
```
`src/my_lib.c`:
```c
#include "my_lib.h"
int add(int a, int b) { return a + b; }
```
## Step 2: Build
```bash
dcr build --release
```
Artifacts:
* `target/\<triple>/release/libmy-lib.a` (Linux)
* `target/release/my-lib.lib` (Windows)
* `target/include/` — header files
## Step 3: Use in another project
```bash
dcr new my-app
cd my-app
dcr add my-lib ../my-lib
```
Automatically:
* Adds include path to `target/include/` of the library
* Adds lib path to `target/\<triple>/release/`
* Links `libmy-lib.a` / `my-lib.lib`

# Build Profiles
Profiles allow overriding `[build]` fields for specific build modes.
## Configuration
```toml
[build]
language = "c"
standard = "c17"
cflags = ["-Wall"]
[build.debug]
cflags = ["-O0", "-g"]
[build.release]
cflags = ["-O3", "-DNDEBUG"]
```
## Merge rules
Fields from `[build.\<profile>]` are merged on top of `[build]`:
* **Scalar fields** (strings, numbers, bools) — replaced
* **Arrays** (`cflags`, `ldflags`, ...) — **appended** (extend the `[build]` array)
Set `inherit = false` to disable array inheritance (only profile's own arrays are used).
## Built-in profiles
The default flags for each profile are composed from three config fields:
| Field | debug default | release default |
| ----------- | ------------------ | --------------- |
| `opt_level` | `"0"` | `"3"` |
| `debug` | `true` | `false` |
| `warnings` | `["all", "extra"]` | `[]` |
Which produce the equivalent compiler flags:
| Profile | Effective flags |
| --------- | ---------------------------------------------------------- |
| `debug` | `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG` |
| `release` | `-O3 -DNDEBUG` |
Additional build options can be toggled per-profile:
```toml
[build.release]
opt_level = "z"
lto = true
strip = true
panic = "abort"
codegen-units = "1"
[build.debug]
opt_level = "1"
debug = false
warnings = ["all", "error"]
```
## Target-specific profiles
```toml
[build.linux]
cflags = ["-DLINUX"]
[build.windows.debug]
cflags = ["-DWIN32", "-O0", "-g"]
```
Application order (highest priority first):
1. `[build.\<target>.\<profile>]`
2. `[build.\<profile>.\<target>]`
3. `[build.\<target>]`
4. `[build.\<profile>]`
5. `[build]`

# Build System
## Compiler Backends
DCR supports 7 compilation backends. Selection is automatic based on file extension and `build.compiler` value.
| Backend | Files | When used |
| --------- | --------------------------------- | ------------------------------------- |
| `unix_cc` | `.c`, `.cpp`, `.cxx`, `.cc`, `.S` | gcc/clang on Linux/macOS/BSD |
| `msvc` | `.c`, `.cpp`, `.cxx`, `.cc` | Windows (cl, clang-cl) |
| `gas` | `.s` | ARM/ARM64 assembler (no preprocessor) |
| `nasm` | `.asm`, `.s` | x86/x86_64 NASM assembler |
| `masm` | `.asm` | MASM (ml/ml64) on Windows |
| `fasm` | `.asm`, `.fasm` | Flat Assembler |
| `llvm_ir` | `.ll` | LLVM IR via `llc -filetype=obj` |
## Qt Support
DCR provides native Qt support for automatic meta-object handling (MOC, UIC, RCC).
Enable it by setting `build.qt = true` in `dcr.toml`. DCR will automatically detect Qt-related files (`.ui`, `.qrc`, `.h` with `Q_OBJECT`) and process them.
```toml
[build]
qt = true
```
*Note: Requires `qt6` modules (Core, Widgets, Gui, Svg) installed via `pkg-config`.*
Advanced customization is still possible via `build.steps` if special handling is needed:
```toml
[build.steps]
moc = "moc {in} -o {out}"
```
### Unix CC
* Compiler resolved via `resolve_compiler()`: `DCR_COMPILER` > `DCR_CC` > `[toolchain]` > `build.compiler` > `PATH`
* Supports `.d` files for header dependency tracking
* Flags: `-std=`, `-MMD -MF`, `-c -o`, `-I`, `-L`, `-l`
* Conditional flags based on config:
* `freestanding` or bare-metal target: `-ffreestanding` (compile), `-nostdlib -static` (link)
* `lto`: `-flto` (compile + link)
* `panic = "abort"`: `-fno-exceptions` (C++ only), `-fno-unwind-tables`, `-fno-asynchronous-unwind-tables`
### MSVC
* Supports cl.exe and clang-cl.exe
* Flags: `/std:`, `/Fo:`, `/Fe:`, `/I`, `/link`
### GAS / NASM / MASM / FASM / LLVM-IR
* GAS: `-I`, `-c -o`, `--defsym`
* NASM: `-I`, `-o`, `-D`, `-f` (format: win64/elf64/macho64/macho32/elf32; **`bin` when `kind = "flat-bin"`**)
* MASM: `/nologo /c /Fo\<obj> <source>`
* FASM: `<source> \<output>` (output path is the object file)
* LLVM IR: `-filetype=obj <source> -o \<output>`
## Incremental Builds
Three levels of incrementality:
1. **mtime** — if output is newer than all inputs, skip
2. **`.d` files** — header change tracking (including transitive)
3. **SHA256 fingerprint** — recompile if compiler flags changed (stored in `.dcr_fingerprint`)
## Parallel Compilation
* `thread::scope` for thread pool
* Atomic task queue (`AtomicU64`)
* Mutex on stdout (`OUTPUT_MUTEX`)
* Thread count = `available_parallelism()`, capped by `build.codegen-units` if set
## Build Kinds
| Kind | Type | Path (Linux example) |
| ----------- | ------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| `bin` | Executable | `target/\<triple>/\<profile>/\<name>` (.exe on Windows) |
| `staticlib` | Static library | `target/\<triple>/\<profile>/lib\<name>.a` (.lib) |
| `sharedlib` | Dynamic library | `target/\<triple>/\<profile>/lib\<name>.so` (.dll/.dylib) |
| `efi` | UEFI application | `target/\<triple>/\<profile>/\<name>.efi` |
| `elf` | ELF without stdlib | `target/\<triple>/\<profile>/\<name>` |
| `none` | Compile only, no link | — |
| `custom` | Full filename+extension control | `target/\<triple>/\<profile>/\<filename>.\<extension>` |
| `flat-bin` | Raw binary | ASM: `\<stem>.bin` (NASM `-f bin` / FASM / GAS·MASM·LLC via objcopy); C/C++: `\<name>.bin` (link + objcopy) |
## Disk images (`[archive]`)
After a successful build, if `[archive]` is present in `dcr.toml`, DCR formats a FAT volume and copies files from `layout` into the image. See [dcr.toml → archive](/docs/reference/dcr-toml#archive).
## Build Steps
DCR supports pre-build and post-build steps:
* `build.steps` — commands before compilation
* `build.post_steps` — commands after compilation
Substitutions: `{stem}`, `{in}`, `{out}`, `{profile}`, `{version}`, `{name}`.
Example Qt codegen via build steps:
```toml
[build.steps]
moc = "moc {in} -o {out}"
```
## pkg-config
Automatic lookup (read from raw config):
```toml
[build]
pkg_config = ["sdl2", "gl"]
```
DCR runs `pkg-config --cflags sdl2 gl` and `pkg-config --libs sdl2 gl` and adds results to compiler/linker flags.
## Variable Substitution
Supported variables:
| Variable | Description |
| ----------------------- | ---------------------------- |
| `{version}` | Package version |
| `{version_major}` | Major version part |
| `{version_minor}` | Minor version part |
| `{version_patch}` | Patch version |
| `{version_suffix}` | Suffix (e.g., `-rc1`) |
| `{version_suffix_dash}` | Suffix with dash |
| `{profile}` | Profile name (debug/release) |
| `{name}` | Package name |

# Cross-Compilation
## Short Names
DCR supports short platform names:
| Short Name | Full Triple |
| ---------- | -------------------------- |
| `linux` | `x86_64-unknown-linux-gnu` |
| `macos` | `x86_64-apple-darwin` |
| `windows` | `x86_64-pc-windows-msvc` |
```bash
dcr build --target windows
```
## Full Triples
```bash
dcr build --target aarch64-unknown-linux-gnu
dcr build --target x86_64-pc-windows-gnu # mingw
dcr build --target armv7-unknown-linux-gnueabihf
```
## clang --target
When using clang, DCR injects `--target=\<triple>` into CFLAGS.
```toml
[build]
compiler = "clang"
target = "aarch64-unknown-linux-gnu"
# Auto: cflags += ["--target=aarch64-unknown-linux-gnu"]
```
## Bare-Metal / Freestanding
For targets containing `none`, `-elf`, `eabi`, or `baremetal`, DCR automatically:
1. **Disables default flags** — no system include paths, no `-l` libc
2. **Injects `-ffreestanding`** at compile time and `-nostdlib -static` at link time
You can also enable freestanding mode explicitly:
```toml
[build]
freestanding = true
```
```bash
dcr build --target aarch64-none-elf
```
## Target Directory
By default, the compilation output directories are structured as follows:
* **Linux and BSD**: Always output to `target/\<triple>/\<profile>/` (using host triple if no target is specified).
* **macOS and Windows (without target)**: Output to `target/\<profile>/`.
* **macOS and Windows (with explicit target)**: Output to `target/\<triple>/\<profile>/`.

### `package.dcr-version`
Optional pin of the DCR CLI the project was written for. On every `dcr.toml` load:

| Equal | Silent |
| Invalid semver | Warning once, field ignored |
Never fails the command — warnings only. Pre-release suffixes (`1.0.0-dev`) are ignored for comparison (`1.0.0-dev` ≡ `1.0.0`).
## [build]
...
* `build.qt` — (bool) Enable automatic Qt meta-object handling (MOC, UIC, RCC). Requires `qt6` modules installed via `pkg-config`.
| Field | Default | Description |
| ---------------- | ------------- | --------------------------------------------------------------------------------------------------------- |
| `language` | `"c"` | `"c"`, `"c++"`, `"cpp"`, `"cxx"`, `"asm"`, `"llvm_ir"`, `"llvm-ir"`, `"ll"` (optional, defaults to `"c"`) |
| `standard` | `"c11"` | C standard (`c11`, `c17`, `c23`) |
| `cxx_standard` | — | C++ standard (`c++17`, `c++20`, `c++23`) |
| `compiler` | `"clang"` | Preferred compiler (optional, defaults to `"clang"`) |
| `kind` | `"bin"` | `bin`, `staticlib`, `sharedlib`, `efi`, `elf`, `none`, `custom`, `flat-bin` |

| `roots` | `["src"]` | Source roots: directories and/or individual source/header files |
| `exclude` | `[]` | Exclude patterns |
| `include` | `[]` | Additional include directories |
| `src_disable` | `false` | Disable auto source discovery |
| `inherit` | `false` | Inherit build from workspace root |
| `clean` | `[]` | Glob patterns for custom clean paths |
| `out_dir` | `""` | Custom output directory |
| `workspace_only` | `false` | Workspace-only, not built standalone (no `language`/`compiler` required) |
| `freestanding` | `false` | Compile in freestanding mode (`-ffreestanding` + `-nostdlib -static`) |
| `opt_level` | — | Optimization level: `0`-`3`, `"s"`, `"z"` (derived from profile if omitted) |
| `debug` | profile-based | Emit debug symbols (`-g`): `true` in debug, `false` in release |
| `lto` | `false` | Link-time optimization (`-flto` for both compiler and linker) |
| `strip` | `false` | Strip symbols from output (`-s` in ldflags) |
| `warnings` | `[]` | Warning flags (e.g. `"all"`, `"extra"`, `"pedantic"`); engine adds `-Wall -Wextra` in debug if empty |
| `panic` | `""` | Panic strategy: `"abort"` disables exceptions and unwind tables |
| `codegen-units` | `""` | Max parallel compilation jobs (`"0"` = auto) |
| `qt` | `false` | Enable automatic Qt meta-object handling (MOC, UIC, RCC) |
Settings from raw config (not in typed struct):
* `pkg_config` — list of packages queried for build-wide compiler/linker flags
Dependencies can also declare a system package directly, for example
`fmt = { pkg-config = "fmt" }`. This records the package in `dcr.lock` and applies
the flags returned by `pkg-config --cflags` and `pkg-config --libs`.
* `ldscript` — linker script path
* `build.steps` / `build.post_steps` — codegen steps
## Per-language overrides: `[build.c]`, `[build.cxx]`, `[build.asm]`, `[build.llvm_ir]`
Each language can have its own table that overrides the flat `[build]` settings:
```toml
[build]
compiler = "clang"
standard = "c11"
[build.c]
standard = "c23"
compiler = "gcc"
[build.cxx]
standard = "c++23"
compiler = "g++"
[build.asm]
compiler = "nasm"
flags = ["-felf64"]
[build.llvm_ir]
compiler = "llc"
```
The flat `[build]` acts as fallback; per-language tables take precedence for their language.
Example:
```toml
[build]
language = "c++"
standard = "c23"
cxx_standard = "c++23"
compiler = "clang"
kind = "sharedlib"
cflags = ["-Wall", "-Wextra"]
opt_level = "z"
lto = true
strip = true
panic = "abort"
codegen-units = "2"
```
## [toolchain]
```toml
[toolchain]
cc = "/usr/bin/clang"
cxx = "/usr/bin/clang++"
as = "/usr/bin/as"
ar = "/usr/bin/ar"
ld = "/usr/bin/ld.lld"
```
Raw config also supports `uic`, `moc`, `rcc` for Qt codegen.
## [dependencies]
See [dependencies](/docs/reference/dependencies).
## [run]
```toml
[run]
cmd = "./target/{profile}/{name}"
```
Substitutions:
* `{version}` — package version
* `{version_major}`, `{version_minor}`, `{version_patch}`, `{version_suffix}`, `{version_suffix_dash}` — version parts
* `{profile}` — debug / release
* `{name}` — package name
Default `cmd` = `./target/{profile}/{name}` (macOS/Windows) or `./target/\<triple>/\<profile>/\<name>` (Linux).
## [workspace]
See [workspaces](/docs/reference/workspaces).
## [archive]
Optional post-build step: format a FAT volume and copy built artifacts into a disk image. Runs after a successful package build (and after workspace member builds that define `[archive]`).
Requires DCR built with the `archive` Cargo feature (`cargo build --features archive`). Release binaries include this feature.
| Field | Required | Description |
| ------------ | -------- | ------------------------------------------------------------------------------------------- |
| `output` | yes | Image path relative to project root (`{profile}` allowed) |
| `format` | yes | `fat12`, `fat16`, or `fat32` |
| `size` | no | Image size: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default `1474560` ≈ 1.44 MiB) |
| `offset` | no | Byte offset of the FAT volume inside the image (default `0`) |
| `label` | no | Volume label (max 11 chars, default `VOLUME`) |
| `bootsector` | no | Path to a 512-byte boot sector written at offset 0 when `offset` is 0 (`{profile}` allowed) |
| `layout` | no | List of `{ from, to }` entries (files or globs → path inside the volume) |
```toml
[archive]
output = "target/{profile}/disk.img"
format = "fat12"
size = "1440K"
label = "MYOS"
bootsector = "target/{profile}/boot.bin"
[[archive.layout]]
from = "target/{profile}/kernel.bin"
to = "KERNEL.BIN"
[[archive.layout]]
from = "assets/*"
to = "/"
```
Typical pairing with `kind = "flat-bin"` (NASM `-f bin`) for bootloaders and pure-ASM OS images.
## `flat-bin` (kind)
Produces a raw binary (default extension `bin`) for boot sectors, kernels, and freestanding payloads.
### Assemblers
| Tool | Language / compiler | How flat-bin is produced |
| ---- | ------------------------------------------ | -------------------------------------------- |
| NASM | `language = "asm"`, `compiler = "nasm"` | `-f bin` → `\<stem>.bin` |
| FASM | `compiler = "fasm"` | direct write (use `format binary` in source) |
| GAS | `compiler = "as"` / `"gas"` | assemble → `objcopy -O binary` |
| MASM | `compiler = "ml"` / `"ml64"` | assemble → `objcopy -O binary` |
| LLC | `language = "llvm_ir"`, `compiler = "llc"` | `-filetype=obj` → `objcopy -O binary` |
```toml
[build]
language = "asm"
compiler = "nasm"
kind = "flat-bin"
extension = "bin"
roots = ["src/boot.asm"]
```
### C / C++
Compile all sources, link with `-nostdlib -static` (plus your `ldflags` / `ldscript`), then convert the intermediate ELF/PE with `objcopy -O binary` to `\<filename|name>.bin`.
```toml
[build]
language = "c"
compiler = "clang"
kind = "flat-bin"
freestanding = true
filename = "kernel"
extension = "bin"
ldscript = "linker.ld"
ldflags = ["-T", "linker.ld"]
```
Notes:
* Multi-file **ASM** packages emit one `\<stem>.bin` per source; **C/C++** emit a single project binary.
* `objcopy` tools tried in order: `llvm-objcopy`, `objcopy`, `gobjcopy`.
* Incompatible with `build.qt = true`.
* `dcr run` rejects `flat-bin` (not a host executable).

# Dependencies
## Formats
The `[dependencies]` section supports registry, path, Git, and `pkg-config` dependencies:
### String (registry)
```toml
[dependencies]
fmt = "10.1.1"
spdlog = "1.12"
catch2 = "3.4.0"
```
The version string is used as-is for registry lookup.
### Table (git)
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0" }
```
Fields: `git`, `branch`, `tag`, `rev`, `mode`, `include`, `lib`, `libs`.
### Table (path)
```toml
[dependencies]
mylib = { path = "../mylib" }
```
For a prebuilt external library, specify its layout explicitly. The three
arrays are paths relative to the dependency root (`include`, `lib`) and linker
names (`libs`):
```toml
[dependencies]
dcr-math = { path = "../deps/dcr-math", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
### Table (`pkg-config`)
Use an installed `.pc` package when the library is provided by the operating system
or another system package manager. DCR invokes `pkg-config --cflags` and
`pkg-config --libs`, preserving include, library, linker, and other flags:
```toml
[dependencies]
fmt = { pkg-config = "fmt" }
openssl = { pkg-config = ["openssl", "libcrypto"] }
```
The `pkg-config` executable must be available in `PATH`. The named `.pc` files must
be available through pkg-config's standard search paths or via `PKG_CONFIG_PATH`.
These dependencies are not downloaded or built by DCR; they are recorded in
`dcr.lock` with a `pkg-config+...` source.
## Registry
DCR uses a package registry for dependency lookup by name.
```toml
# ~/.dcr/config.toml
[registry.default]
url = "https://index.dcr.dexoron.tech"
priority = 1
```
Registry priority: order in `config.toml`. The `DCR_INDEX_PATH` variable overrides the path to `index.json`.
## Git dependencies
Git dependencies are cloned into `~/.dcr/git/`; their exact checked-out commit is written to `dcr.lock`.
Both Git and path dependencies have two modes:
* **DCR package:** the source has `dcr.toml`. DCR builds it before the consumer and uses the package name from its manifest for linking.
* **Prebuilt library:** it provides existing headers and binaries through `include`, `lib`, and `libs`. DCR passes them to the compiler/linker without building the dependency.
The mode is normally detected automatically. Use `mode = "build"` or `mode = "prebuild"` when a source contains both a manifest and prebuilt artifacts and you need to choose explicitly.
`dcr-math-lib` publishes both forms. Select its prebuilt library explicitly:
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0", mode = "prebuild", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
DCR supports specifying branch/tag/rev for git sources:
* `branch` — switch to a branch
* `tag` — switch to a tag
* `rev` — switch to a specific commit
* `features` — feature flags (parsed, but does not affect build)
## Path dependencies
Local paths may point at a DCR package or a prebuilt external library. A path DCR package is built before its consumer, including its own path/git dependencies. DCR detects dependency cycles. A prebuilt library is never built by DCR; it is linked from the directories declared in its dependency entry.
```toml
[dependencies]
mylib = { path = "/abs/path/to/lib" }
mylib = { path = "../relative/path" }
```
For DCR packages, the package name from `dcr.toml` is used for linking (so the dependency key may differ from the library name). Header resolution includes the packaged `target/include` directory and link search includes `target/lib`.
### Recommended library layouts
Buildable DCR library:
```text
dcr-math-lib/
├── dcr.toml
└── src/
├── dcr_math.c
└── dcr_math.h
```
Prebuilt library:
```text
dcr-math-lib/
├── include/
│ └── dcr_math.h
└── lib/
└── libdcr-math.a # or .so / .lib
```
`libs` contains linker names without the `lib` prefix and file extension: use
`["dcr-math"]` for `libdcr-math.a`.
If one repository contains both forms, keep the prebuilt files in `include/` and `lib/` and select the mode explicitly:
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0", mode = "prebuild", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
For a local copy, replace `git` with `path = "../dcr-math-lib"`. In `prebuild` mode DCR does not run the dependency build, even when `dcr.toml` is present.
## dcr.lock
Dependency lock file. Contains package names and sources.
Created during `dcr build` for resolved registry, path, and Git dependencies. Not updated during `dcr add` — only on the next `dcr build`.
## Resolution process
1. Resolve dependency sources (registry → git → path)
2. Fetch git dependencies into `~/.dcr/git/` and check out the requested ref
3. Build DCR package dependencies recursively
4. Collect `include_dirs`, `lib_dirs`, `libs` for the compiler

# Environment Variables
## DCR_COMPILER
Overrides the compiler for all languages. **Highest priority.**
```bash
export DCR_COMPILER=clang
dcr build
```
Compiler resolution priority:
1. `DCR_COMPILER` (env)
2. `DCR_CC` / `DCR_CXX` / `DCR_AS` (env)
3. `[toolchain]` (dcr.toml)
4. `build.compiler` (dcr.toml)

# Platform Support
## Target Triples
DCR normalizes target triples. Short platform names are expanded to full triples.
### Linux
```
target/<arch>-unknown-linux-<env>/<profile>/
```
Architectures: `x86_64`, `aarch64`, `i686`, `armv7`, `riscv64` (host-detected).
Environments: `gnu` (default), `musl`.
Artifact type: ELF. Extensions: `.so` (sharedlib), `.a` (staticlib).
### macOS
```
target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
```
Architectures: `x86_64`, `aarch64` (host-detected).
Extensions: `.dylib` (sharedlib), `.a` (staticlib).
### Windows
```
target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
```
Architectures: `x86_64`, `aarch64`.
Environments: `msvc` (default), `gnu` (MinGW).
Extensions: `.exe` (bin), `.lib` (staticlib), `.dll` (sharedlib), `.efi` (UEFI).
### BSD
```
target/<arch>-unknown-<os>/<profile>/
```
Supported systems: `freebsd`, `openbsd`, `netbsd`, `dragonfly`.
## Host Detection
DCR uses `std::env::consts::ARCH` and `std::env::consts::OS` for host platform detection. Used as fallback when `target` is not specified.

sidebar_label: Workspaces

# Workspaces
Workspaces allow managing multiple packages in a single repository.
## Configuration
```toml
[workspace.lib-core]
path = "lib-core"
[workspace.lib-utils]
path = "lib-utils"
deps = ["lib-core"]
[workspace.app]
path = "app"
deps = ["lib-core", "lib-utils"]
main = true
```
### Member fields
| Field | Description |
| ------ | ------------------------------------------------ |
| `path` | Path to the package (relative to workspace root) |
| `deps` | Dependencies on other members |
| `main` | Mark as the main package |
## Topological sort
DCR automatically sorts packages by dependencies: package A is built before B if B depends on A.
Cyclic dependencies are detected and cause an error.
## Build
```bash
dcr build # build all packages in dependency order
dcr build --workspace app # build only app (dependencies built automatically)
```
When building a workspace, DCR automatically injects include and library paths of dependent workspace members:
* **Include Paths**: Automatically resolves and injects header directories of dependencies, including the member's `src/` directory, local `include/` directory, and the packaged `target/include` directory.
* **Library Paths**: Injects compiled library search paths (`target/lib` as well as target-specific build folders) to allow automatic linking with member libraries.
## Clean
```bash
dcr clean # clean only root target/
dcr clean --all # clean target/ of all packages
```
## Inheritance
If a member has `inherit = true` in its `[build]` section, fields from the root `[build]` are merged into the member:
```toml
# root dcr.toml
[build]
inherit = true
language = "c"
standard = "c17"
# member inherits language and standard
```
## Workspace-only root (no build of its own)
A workspace root can set `workspace_only = true` — it won't be built itself, and doesn't need `language` or `compiler`:
```toml
[package]
name = "my-workspace"
version = "0.1.0"
[build]
workspace_only = true
kind = "bin"
[workspace]
lib-core = { path = "lib-core" }
app = { path = "app", deps = ["lib-core"] }
```

sidebar_label: Self Update
---
# Self Update
## dcr --update
Automatic update to the latest version. Downloads a binary (not an archive) from GitHub Releases and replaces the current executable.
```bash
dcr --update
```
## How it works
1. DCR detects the current platform and architecture
2. Fetches the latest release from `api.github.com/repos/dexoron/dcr/releases/latest`
3. Compares versions
4. Downloads the matching asset (direct binary URL, not archive)
5. Replaces the current executable via `self_replace`
## Asset naming
Pattern: `dcr-\<triple>` or `dcr-\<triple>.exe`
| Platform | Asset name |
| -------------- | -------------------------------- |
| Linux x86_64 | `dcr-x86_64-unknown-linux-gnu` |
| macOS x86_64 | `dcr-x86_64-apple-darwin` |
| macOS ARM64 | `dcr-aarch64-apple-darwin` |
| Windows x86_64 | `dcr-x86_64-pc-windows-msvc.exe` |
## AUR
If DCR was installed via AUR, `--update` shows a warning:
```
Update via package manager: yay/paru -Syu {package_name} or sudo pacman -Syu {package_name}
```
## Errors
* Cannot detect platform — error
* Cannot fetch release — error with URL
* No write permission — error (use `sudo` or manual install)

sidebar_label: Test framework (EXPECT, TEST, ...)
---
# Test Framework
DCR has a built-in minimal test framework for C.
## Macros
### `EXPECT(expr)`
Asserts that an expression is true.
```c
EXPECT(1 + 1 == 2);
EXPECT(ptr != NULL);
```
### `SKIP(reason)`
Skips a test with a message.
```c
SKIP("not implemented on Windows");
```
### `TEST(name)`
Defines a test.
```c
TEST(addition) {
EXPECT(1 + 1 == 2);
EXPECT(2 + 2 == 4);
}
```
### `TEST_CASE(name)`
Registers a test case.
```c
TEST_CASE(math) {
EXPECT(1 + 1 == 2);
}
```
## Initialization
```bash
dcr test --init
```
Creates:
* `tests/dcr_test.h` — framework header (do not edit)
* `tests/test.c` — template with example test
## Structure
```
tests/
├── dcr_test.h # framework (do not edit)
├── test.c # main tests
└── ... # additional .c test files
```
Only `.c` files are compiled (`.cpp` is not supported).

# Changelog
## 0.9.1 (2026-09-13)
* **`pkg-config` dependencies** — declare `fmt = { pkg-config = "fmt" }` or multiple package names in `[dependencies]`; DCR applies `.pc` compiler/linker flags and records the resolved package in `dcr.lock`.
* **`dcr add` support for `pkg-config`** — easily add system package dependencies with `dcr add fmt pkg-config:fmt` or `dcr add openssl pkg:openssl,libcrypto`.
* **`dcr tree` & IDE integration** — `pkg-config` packages are marked in `dcr tree` and resolved into compiler flags in `dcr gen` (`compile_commands.json`).
* **Fixed `dcr new` in non-ASCII / spaced paths** — initializing projects from folders with non-ASCII characters or spaces no longer fails validation.
## 0.9.0 (2026-08-31)
* **Download mirrors in `dcrup`** — `--mirror auto|cf|gh|sf|ya` and `DCRUP_MIRROR`.
Default `auto` tries **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
* **Complete Path/Git dependencies** — DCR packages from `path` and `git` are built before their consumer. Git sources are cached in `~/.dcr/git`, support `branch`/`tag`/`rev`, and record the exact commit in `dcr.lock`.
* **Build and prebuild modes** — `path` and `git` dependencies can build a DCR package from `dcr.toml` or link existing `include`/`lib`/`libs` artifacts; `mode = "build"` / `"prebuild"` selects explicitly when both forms are present.
* **Prebuilt dependency examples** — documentation now shows the `dcr-math-lib` Git repository and recommended build/prebuilt layouts for both `git` and `path`.
* **Transitive dependency builds and cycle reporting** — DCR recursively builds DCR packages and reports a clear dependency chain for cycles.
* **Bare path arguments for `dcr add`** — `dcr add mylib ../mylib` now works in addition to the explicit `path:` form.
* **Removed `install.sh` / `install.ps1` / `install_bsd.sh`** — superseded by `dcrup`.
## 0.8.5 (2026-08-08)
* **`package.dcr-version`** — optional CLI version pin in `dcr.toml`.
`dcr new` / `dcr init` write the current version. On config load:
* missing / empty pin → warn "add dcr-version";
* dcr older than pin → warn "update dcr";
* dcr newer than pin → warn "check changelog, update pin";
* equal → silent.
Commands do not fail, warning only (once per path per process).
## 0.8.4 (2026-08-04)
**Added:**
* **`.dcr/` directory** — shared machine-readable build facts for IDE integrations:
* `.dcr/compile_commands.json`
* `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
* `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
* `.dcr/ide/` (placeholder for IDE lock files)
* **`dcr gen project-info`** — `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; absolute/canonical paths.
* **`dcr build --print-artifact-path`** — one absolute artifact path line on stdout after a successful build.
* **`dcr gen … --quiet` / `-q`** — suppress human success logs for gen subcommands.
* **`.clangd`** — created on first gen with `CompilationDatabase: .dcr` (`# managed by dcr gen`); custom `.clangd` is not overwritten.
* **Helpers** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` via `platform::*`.
* **`dcr new` / `dcr init`** — add `.dcr/` to `.gitignore`.
**Changed (breaking):**
* **`compile_commands.json` moved** from project root to **`.dcr/compile_commands.json`**.\
clangd discovers it via `.clangd` / `--compile-commands-dir=.dcr`.\
CLion and VSCode generators updated accordingly.
* **Atomic write** for compile_commands (tmp + rename).
* **`gen vscode` / `gen clion` launch/run** — use the same artifact path resolver as `project-info` / `build-info.json`.
**Fixed:**
* Launch configs no longer hardcode `target/\<profile>/\<name>` without the Linux triple segment.
* Symlink/mount roots: best-effort canonicalize for root and compile database paths.
## 0.8.3 (2026-08-03)
### Added
* **`dcr run -- \<args>...`** — cargo-style argument forwarding after a bare `--`\
(`dcr run --release -- --test_help`). Applies to direct binary runs and `[run].cmd`.
* **Tests** — host target section `ldflags` without CLI `--target`; run-arg forwarding; `split_double_dash` unit tests.
### Changed
* **Native builds resolve the host triple** — without `--target` / package `build.target`, host sections such as\
`[build.x86_64-unknown-linux-gnu]` apply again (`cflags` / `ldflags` / toolchain).\
Previously the target was empty and those sections were ignored while artifacts already used the host triple path.
* **Empty target** — no more `Unknown target ''` warning.
* **`dcr run --help` / man `dcr-run`** — document `--` forwarding.
### Fixed
* **Native artifact paths on Windows and macOS** — without an explicit `--target` / `build.target`, artifacts use `target/\<profile>`, so `dcr run` and flat-bin find the build output.
* Target-specific `ldflags` missing on native host builds (e.g. micro-lang + `libsct-elf`).
* Spurious empty-target warning.
## 0.8.2 (2026-07-22)
### Added
* **Compile progress `[N/M]`** — live TTY status line (`compile pkg v0.1.0 [12/41]`) so long mono-package builds do not look hung.
* **DCR status style** — fixed-width verbs: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run`.
* **Cargo feature `archive`** — optional FAT packing via `fatfs` (`cargo build --features archive`). Release CI builds with the feature; without it `[archive]` fails with a clear message.
* **Tests** — `flat_bin_nasm_build`, package `build.target` without CLI `--target`, stricter workspace `clean --all`.
* **CI expansion** — unit + integration on Linux/macOS/Windows, archive feature job, rust-cache, clippy default + all-features (see `.github/workflows/ci.yml`).
### Changed
* **No forced host triple from CLI** — without `--target`, package/member `build.target` is honored (bare-metal / ISO `post_steps` paths).
* **Relative include/lib flags** (`-I`, `-i`, `-isystem`, `-idirafter`, `-L`, `-T`) absolutized against the package root under workspace builds.
* **`dcr clean --all`** — no spam for members without a local `target/` (shared root `target/`).
* **`error` / `warn`** — red / yellow on stderr; CLI fully English (`Hint:`).
* **Help / man** — list `add`, `lint`, `setup`; unknown command exits with code 1.
* **Tool NotFound** — `linker not found: ld.lld …` / `{tool} not found …` instead of raw `os error 2`.
## 0.8.1 (2026-07-20)
### Added
* **`build.kind = "flat-bin"`** — raw binary (default `.bin`) for OS-dev payloads:
* **NASM** — `-f bin` → `\<stem>.bin`
* **FASM** — direct output (`format binary` in source)
* **GAS / MASM / LLC** — object → `objcopy -O binary` → `\<stem>.bin`
* **C/C++** — objects → freestanding link → `objcopy -O binary` → `\<name>.bin`
* Requires `llvm-objcopy` / `objcopy` / `gobjcopy` except for NASM/FASM direct emit
* **`[archive]` section** — FAT12/16/32 disk images after build (`output`, `format`, `size`, `offset`, `label`, `bootsector`, `layout`). From 0.8.2 requires feature `archive`.
* **Single-file `build.roots`** — a root may be a single source or header file, not only a directory.
### Changed
* **`--force`** also re-runs `build.steps` and `build.post_steps`.
* **`dcr run` on workspace-only root** — if `[run].cmd` is set, run that after build; otherwise delegate to a workspace member.
## 0.8.0 (2026-07-18)
### Added
* **Dedicated Build Engine (`src/core/build/engine.rs`)** — decoupled the build orchestration logic completely from the CLI front-end wrapper in `src/cli/build.rs` to a reusable, decoupled core build engine.
* **Polymorphic Language Model (`Language` trait)** — introduced the abstract `Language` trait (`src/core/build/language/mod.rs`). File scanning, compiler resolution, and flags handling are now encapsulated in dedicated language modules for C, C++ (including Qt code generation), LLVM IR, and ASM (GAS, NASM, FASM, MASM).
* **Polymorphic Compilation Dispatch (`Builder` trait)** — introduced the `Builder` trait to generalize builder invocations (`src/core/build/builder/mod.rs`). Consolidated GCC/Clang logic into `builder/cc_common.rs` and Microsoft Visual C++ logic into `builder/msvc/`.
* **Per-Language Configuration overrides (`[build.\<lang>]`)** — introduced support for configuring language-specific compiler, standard, and flags (e.g. `[build.c]`, `[build.cxx]`, `[build.asm]`) independently in `dcr.toml`.
* **Automatic Workspace Dependency Injection** — during workspace builds, include/lib paths of dependent workspace members (including their source headers, local `include/` folders, and build target `target/include` / `target/lib` folders) are automatically resolved and injected.
* **`BuildReporter` Event System** — decoupled build orchestration output into a structured event-driven reporter model (`src/core/build/report.rs`), making DCR suitable for library embedding and IDE integrations without stderr capturing.
* **Build Cancellation Support** — introduced thread-safe cancellation tokens (`Arc\<AtomicBool>`) allowing clients to safely abort compile runs mid-execution.
* **TOML Formatting & Custom Keys Preservation** — migrated the config editor to `toml_edit`, preserving all unknown/user-defined TOML keys, structures, and comments during file write operations (e.g., in `dcr add`).
* **Path Dependencies Target Include Resolution** — local path dependencies configured via tables now correctly expose headers built and packaged into their `target/include` folder to consumer packages.
* **Modular Integration Test Suite** — refactored the monolith `tests/cli_basic.rs` file into clean, specialized integration tests: `cli_build.rs`, `cli_deps.rs`, `cli_lint.rs`, `cli_new.rs`, `cli_qt.rs`, `cli_test.rs`, `cli_workspace.rs`.
### Changed
* **Consolidated Linking and Archiving** — artifact generation (linking executables/shared libraries and archiving static libraries) consolidated into a single `src/core/build/builder/artifact.rs` module.
* **Workspace-Aware member execution** — `dcr run` executed at the workspace root of a `workspace_only` project now triggers the member build inside the workspace context using the `--workspace` parameter, preventing standalone build issues.
* **Elimination of Global State** — removed global variables and states from the build core, encapsulating build logic inside isolated `BuildContext` structs for thread safety.
* **Build Cache Separation** — relocated mtime tracking, incremental caching, and header-dependency checking logic to `src/core/build/cache.rs`.
* **Modularized Pre-build Steps** — decoupled generator scripts and pre-build commands parsing into `src/core/build/steps.rs`.
## 0.7.4 (2026-06-17)
### Added
* **Native Qt support** — automatic meta-object handling (MOC, UIC, RCC) added when `build.qt = true` is set in `dcr.toml`.
* **`dcr lint` command** — C/C++ static analysis via `clang-tidy`. Supports `--fix` for automatic fixes. Respects `build.roots` and `build.src_disable` from config.
* **Three new assembler backends**:
* **MASM** (`compiler = "ml"` / `"ml64"`) — Microsoft Macro Assembler.
* **FASM** (`compiler = "fasm"`) — Flat Assembler.
* **LLVM IR** (`compiler = "llc"`) — compiles `.ll` files via `llc -filetype=obj`.
* **Shared ASM pipeline** — linking and archiving logic consolidated into `core/builder/asm.rs`. Adding a new assembler backend now takes ~30 lines.
* **Filesystem utilities** — `to_hex()` and `home_dir()` extracted to `utils/fs.rs`.
* **Build utilities** — `normalize_target()`, `normalize_kind()`, `normalize_platform()`, `default_profile_flags()` extracted to `utils/build.rs`.
* **Backend helpers** — `asm_lang_flag()`, `source_extensions()`, `elapsed_secs()` added to `core/builder/common.rs`.
* **Full Bare-Metal / Freestanding Automation** — introduced the `build.freestanding = true` configuration option. When enabled (or when a bare-metal target is detected), DCR automatically injects `-ffreestanding` during compilation and both `-nostdlib` and `-static` during linking.
* **Artifact Optimization (LTO & Strip)** — added `build.lto` (auto-injects `-flto` for compiler and linker) and `build.strip` (automatically strips debug symbols via linker `-s` flag) options to `dcr.toml`.
* **Compilation Thread Control** — added the `build.codegen-units` option to strictly limit the maximum number of parallel jobs utilized by the custom `parallel_build` worker pool.
* **Panic Behavior Management** — added `build.panic = "abort"` support. For C++ targets, it automatically strips exception handling and unwind tables via `-fno-exceptions`, `-fno-unwind-tables`, and `-fno-asynchronous-unwind-tables`.
### Changed
* **Intelligent Default Flags Generation** — automated injection of fallback optimization (`-O3`/`-O0`), debug (`-g`), and warning (`-Wall -Wextra`) flags is now suppressed for bare-metal and freestanding builds if `build.cflags` are overridden.
* **Centralized Bare-Metal Detection** — relocated the `is_bare_metal_target` helper to common build utilities (`src/utils/build.rs`) for unified access across the building core.
* **Architectural Refactoring**:
* Renamed `src/config.rs` to `src/templates.rs`.
* Started consolidation of configuration and build orchestration logic.
## 0.7.3 (2026-06-13)
### Added
* **`--vcs` option for `new` and `init` commands** — introduced explicit version control system selection via `--vcs \<git|none>`.
* **Git metadata integration in `--version`** — the CLI now appends the current short commit hash and a `-dirty` suffix if there are uncommitted changes in the DCR repository.
* **Automatic `.gitignore` generation** — Git repository initialization now automatically writes a `.gitignore` file excluding the `/target` directory.
* **Nested repository prevention** — automatic Git initialization is now skipped if `dcr new` or `dcr init` is executed inside an already existing Git repository.
* **VCS verification tests** — added `new_vcs_options_work` and `init_vcs_options_work` integration tests to ensure reliable repository behavior.
### Changed
* **Complete removal of `git2` dependency** — all Git actions (dependency fetching, VCS setup, status checks) are now delegated to the system `git` executable via `Command`. This simplifies compilation and drops the need for `vendored` and `openssl` features.
* **Migrated from `reqwest` to `ureq`** — replaced the heavy `reqwest` crate in `flag_update.rs` with the lightweight synchronous `ureq 2.10` client, reducing overhead and the final binary size.
## 0.7.2 (2026-06-07)
### Added
* `default_target_triple()` now respects `target_env` — Linux (gnu/musl) and Windows (msvc/gnu) use the correct environment instead of hardcoded values.
### Fixed
* **macOS Apple Silicon builds failed with `_main` undefined** — `--target=` is now passed to ldflags, not just cflags. `default_target_triple()` uses `std::env::consts::ARCH` on macOS instead of hardcoded `x86_64`.
* **GitHub Stars and GPL-3.0 badges not rendering in README** — badge block converted to pure HTML.
### Changed
* Default target resolution extracted into shared `default_target_triple()` — removed duplication across build, run, clean.
## 0.7.1 (2026-06-02)
### Added
* **`--help` for all commands** — `dcr build --help`, `dcr run --help`, `dcr new --help`,
`dcr init --help`, `dcr clean --help`, `dcr add --help`, `dcr fmt --help`,
`dcr setup --help`, `dcr tree --help`, `dcr gen --help`, `dcr --update --help`,
`dcr test --help`. All output uses styled headers (green) and usage lines (cyan).
* **Man pages** — 12 troff pages in `man/man1/`: `dcr.1`, `dcr-build.1`,
`dcr-run.1`, `dcr-new.1`, `dcr-init.1`, `dcr-clean.1`, `dcr-add.1`, `dcr-test.1`,
`dcr-gen.1`, `dcr-fmt.1`, `dcr-tree.1`, `dcr-setup.1`.
* **Man pages in all packaging** — install.sh, install_bsd.sh, AUR PKGBUILD,
Debian (cargo-deb), RPM (cargo-generate-rpm), Nix (postInstall), Homebrew
(resource), Snap, GitHub Release assets.
* **Project name validation** — `dcr init` and `dcr new` now validate names before
creating files. Only ASCII letters, digits, `_` and `-` are allowed.
* **`documentation` and `homepage` fields** — added to `Cargo.toml`.
* **Release profile optimizations** — `opt-level = "z"`, LTO, `codegen-units = 1`,
`panic = "abort"`, `strip = true` for smaller binaries.
* **Linux i686, armv7, riscv64 targets** — added to release workflow and install scripts.
* **Linux musl i686, armv7 targets** — cross-compiled via zigbuild in CI.
* **AUR packages** — `dcr-dev`, `dcr-dev-bin` publishing workflow.
* **Snap publishing** — automated Snapcraft publishing in CI.
* **Snap badge** — in README.
### Changed
* **`validate_package_name` made public** — callable from CLI commands.
* **README platform table** — reorganized: libc variants as separate OS rows,
removed extra columns. Linux architecture list updated.
* **`gen.rs` no-args output** — now uses styled output instead of raw `eprintln!`.
* **`tree.rs`, `fmt.rs`, and `setup.rs`** — now accept arguments for `--help`.
* **README install commands** — `| bash` → `| sh` for POSIX compatibility.
### Fixed
* **`dcr new \<invalid-name>` creates directory then fails** — validation now
happens before any file operations.
* **`dcr init` on invalid directory name** — same fix.
* **Man pages missing in installed packages** — now shipped in all formats.
* **Windows drive letter false positive** — in dependency file parser.
* **CRLF (`\r\n`) breaks dependency parser** — now handles mixed line endings.
* **Newline after backslash not consumed** — in `parse_d_file` escape handling.
## 0.7.0 (2026-06-01)
### Added
* **OpenBSD and NetBSD target support** — full platform routing with dynamic target triples using `std::env::consts::ARCH` and `std::env::consts::OS`. Affects `build`, `run`, `clean` commands and the platform module.
* **`src/platform/bsd.rs`** — new BSD platform module (shared by FreeBSD, OpenBSD, NetBSD) providing `bin_path`, `lib_path`, `elf_path`, `efi_path`, `shared_lib_path`.
* **`build.out_dir` config option** — custom output directory that overrides the default `target/\<triple>/\<profile>` path for final artifacts. Supported in `build`, `run`, and config validation.
* **`dcr fmt` command** — new CLI command that formats all C/C++ source files (`*.c`, `*.cpp`, `*.h`, `*.hpp`) in `src/` and `tests/` using `clang-format`.
* **Incremental linking** — `needs_link()` in `common.rs` checks if any object file is newer than the linked output, skipping unnecessary relinking. Implemented for all backends (`unix_cc`, `msvc`, `gas`, `nasm`).
* **`build.kind = "none"` and `"custom"`** — two new project kinds for special build scenarios that don't produce standard artifacts.
* **`install_bsd.sh`** — POSIX-compliant installation script for BSD systems (FreeBSD, OpenBSD, NetBSD) with binary download and source build modes.
* **Linux ARM64 support in `install.sh`** — added `Linux:aarch64|Linux:arm64` target detection for pre-built binary downloads.
* **BSD OS detection in `install.sh`** — detects FreeBSD, OpenBSD, NetBSD and determines target triple.
* **`rust-toolchain.toml`** — explicit toolchain pinning to `stable` channel.
* **Integration tests** — `build_with_target_config` (verifies `build.target = "linux"`) and `build_with_out_dir` (validates custom output directory).
* **`get_build_string_with_profile` made `pub`** — so `run.rs` can determine custom output directory configuration.
### Changed
* **`build.target` semantics changed** — now strictly contains a target triple (e.g., `x86_64-unknown-linux-gnu`) or short name (`linux`, `macos`, `windows`). No longer used as custom output directory — this functionality moved to `build.out_dir`.
* **`build.standard` made optional** — changed from `String` to `Option\<String>`. Validation only enforces non-empty for non-ASM languages. Skipped in `dcr.toml` output if empty.
* **`dcr run` with `out_dir`** — now determines target directory respecting `build.out_dir` via `get_build_string_with_profile()` from `build.rs`.
* **`collect_sources()` returns empty vector** instead of error when no sources are found, allowing `kind = "none"` or `kind = "custom"` projects with no source files.
* **CI/CD release workflow refactored** — `git2` made target-specific (no vendored-openssl on Windows), Zig-based cross-compilation for non-x86_64 Linux targets, Arch Linux package version cleanup (dashes → dots), `gmake` symlink for NetBSD.
* **README compatibility table** — FreeBSD, OpenBSD, NetBSD build/run status upgraded from "community/best-effort" to "officially supported".
* **Documentation updated** — `build-section.md` describes new `build.target` and `build.out_dir` fields. `target-directory.md` rewritten to clarify the distinction.
### Fixed
* **stdout/stderr not inherited in `dcr run`** — child process output was captured and manually printed, breaking interactive programs. Fixed by switching to `Command::status()`.
* **Race condition in release CI** — matrix build jobs could upload assets to a release that didn't exist yet. Fixed by adding a dedicated `create-release` job.
* **Release GHA — stable toolchain override** — fixed Rust toolchain override issues in CI.
* **Arch Linux package version sanitization** — version strings with dashes (e.g., `0.7.0-dev`) are invalid for `pkgver`. Fixed by replacing dashes with dots.
* **GPG permissions after Docker** — Docker operations changed GPG directory ownership. Fixed by running `chown` after Docker commands.
* **RPM artifact paths** — RPM artifacts were placed in `rpm/x86_64/` instead of `fedora/x86_64/`. Fixed in Dexoron Packages Index workflow.
* **JSON parsing reliability in `install.sh`** — added `jq` as primary parser with `python3` fallback for dev channel release lookup.
### Removed
* **`format_roots()` helper function** — removed from `common.rs`. Was only used by the old error handling path in `collect_sources()`.
* **Per-distribution artifact download steps** — three separate `actions/download-artifact` steps replaced with unified `gh release download --clobber`.

# Build Commands
## `dcr build`
Builds the project according to `dcr.toml`.
```bash
dcr build # debug profile
dcr build --release # release build
dcr build --debug # explicit debug
dcr build --target aarch64-unknown-linux-gnu
dcr build --force # full rebuild (also re-runs build.steps / post_steps)
dcr build --clean # clean + build
dcr build --verbose # show compilation commands
dcr build --workspace pkg-a # build specific workspace package
```
Artifacts: `target/\<triple>/\<profile>/\<binary-name>` (Linux with explicit target).
With `[archive]` in `dcr.toml`, a FAT disk image is packed after a successful build.
## `dcr run`
Builds (if sources are newer than artifacts) and runs the binary.
```bash
dcr run
dcr run --release
dcr run --force # force rebuild then run
```
On a **workspace-only** root: if `[run].cmd` is set, that command is used after build; otherwise DCR delegates to a workspace member.
## `dcr clean`
Removes `target/` directory (or `target/\<target>/\<profile>`).
```bash
dcr clean
dcr clean --release # target/release/ only
dcr clean --target windows # target/x86_64-pc-windows-msvc/
dcr clean --all # clean all workspace packages
```

# Dependency Commands
## `dcr add \<name> [source]`
Adds a dependency to `dcr.toml`.
```bash
dcr add fmt # registry lookup
dcr add mylib ../path/to/lib # path as source
dcr add mylib path:./lib # explicit path prefix
dcr add mylib git:https://github.com/user/repo # explicit git prefix
dcr add mylib github:user/repo # GitHub shorthand
dcr add mylib gitlab:user/repo # GitLab shorthand
dcr add fmt pkg-config:fmt # system package via pkg-config
dcr add openssl pkg:openssl,libcrypto # multiple pkg-config packages
```
Source prefixes:
* `path:` — local path
* `git:` — generic git URL
* `github:` — expands to `https://github.com/\<user>/\<repo>`
* `gitlab:` — expands to `https://gitlab.com/\<user>/\<repo>`
* `pkg-config:` / `pkg:` — one or more packages resolved by `pkg-config`
* `http://` / `https://` / `git@` — full URL
Flags:
* `--branch \<name>` — git branch
* `--tag \<name>` — git tag
* `--rev \<hash>` — git commit
If source is omitted — DCR searches connected registries. A bare relative or absolute path is accepted as a path dependency.
For `pkg-config` dependencies, the referenced packages must already be installed
and provide `.pc` files. DCR invokes `pkg-config` during the build (using
`PATH` and `PKG_CONFIG_PATH`) and forwards the returned compiler and linker
flags; it does not download or build these packages.
## `dcr tree`
Displays the project dependency tree.
```bash
dcr tree
```
Example output:
```
my-app v0.1.0
├── fmt (registry)
│ └── spdlog (registry)
└── catch2 (registry)
```
For path dependencies, recursively shows their own dependencies (from their `dcr.toml`).

# Project Commands
## `dcr new \<name>`
Creates a new project with a standard structure and `dcr.toml`. The `name` argument is required.
Only ASCII letters, digits, underscores `_` and hyphens `-` are allowed in the project name.
```bash
dcr new my-app
dcr new my-app --vcs none
```
Flags:
* `--vcs \<git|none>` — Initialize version control system (defaults to `git` if available, or `none`).
Generates:
* `dcr.toml` with basic fields
* `src/main.c` with a `main` template
## `dcr init`
Initializes a DCR project in the current (empty) directory.
```bash
dcr init
dcr init --vcs none
```
Flags:
* `--vcs \<git|none>` — Initialize version control system (defaults to `git` if available, or `none`).
The project name is taken from the current directory name. The directory name must follow the same naming rules as `dcr new`.

# Quality Commands
## `dcr test`
Runs tests.
```bash
dcr test # debug profile
dcr test --release # release profile
dcr test --debug # explicit debug
dcr test --help # detailed help
```
Before first use, initialize tests:
```bash
dcr test --init
```
This creates `tests/dcr_test.h` (framework) and `tests/test.c` (template).
What `dcr test` does:
1. Builds the project
2. Collects `tests/*.c` files (`.c` only, not `.cpp`)
3. Compiles and links each test file
4. Runs each test binary
5. Prints summary: TOTAL, PASS, SKIP, FAIL
6. Returns non-zero exit code on any FAIL
## `dcr fmt`
Formats C/C++ source files using `clang-format`.
```bash
dcr fmt
```
Processes: `src/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}` and `tests/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}`.
Uses `.clang-format` at the project root (if present), otherwise default clang-format style.
## `dcr lint`
Runs `clang-tidy` on C/C++ source files for static analysis.
```bash
dcr lint # show diagnostics
dcr lint --fix # apply fixes automatically
dcr lint --help # detailed help
```
Processes: `src/**/*.{c,cpp,cxx,cc}` and `tests/**/*.{c,cpp,cxx,cc}`.
Without `--fix`, clang-tidy reports warnings and errors without modifying files.
With `--fix`, clang-tidy applies automatic suggestions in place.

# FAQ
## Registry not found
```
error: registry not found
```
**Solution:** Make sure `~/.dcr/config.toml` exists:
```toml
[registry.default]
url = "https://index.dcr.pm"
priority = 1
```
And check `DCR_INDEX_PATH`:
```bash
echo $DCR_INDEX_PATH
```
## Compiler not found
```
error: compiler not found
```
**Solution:** Ensure a compiler is installed and available in PATH.
```bash
which gcc
which clang
```
Or specify explicitly via `[toolchain]` in `dcr.toml`.
## Ctrl+C during build
DCR handles SIGINT: interrupts the current compilation and exits with non-zero code.
## How to create a library?
See [Library Recipe](/docs/recipes/library-project).
## How to cross-compile to Windows?
See [Cross-Compile Recipe](/docs/recipes/cross-to-windows).
## How to create a multi-package project?
See [Workspace Recipe](/docs/recipes/multi-package-workspace).
## Bootloader / pure NASM OS image
Use `kind = "flat-bin"` (NASM `-f bin`) and optional `[archive]` for a FAT disk image.
See [OS-dev recipe](/docs/recipes/os-flat-bin-archive).
## How do I choose a download mirror?
`dcrup install` uses `--mirror auto` by default and tries **cf → gh → sf → ya**.
```bash
dcrup install stable --mirror cf
export DCRUP_MIRROR=ya
```
## Lock file
`dcr.lock` is created during builds (`dcr build`) when registry dependencies are present. To force an update — delete `dcr.lock` and run `dcr build`.

# Installation
## dcrup (recommended)
Install and switch DCR versions (stable / dev / night, pin `0.8.2`, optional build from source).
### Linux / macOS / BSD / Windows (bash)
```sh
curl -fsSL https://sh.dcr-tool.ru | sh -s -- self-install
export PATH="$HOME/.dcr/bin:$PATH"
dcrup install stable
```
Non-interactive install of DCR in one shot:
```sh
curl -fsSL https://sh.dcr-tool.ru | sh -s -- install stable
export PATH="$HOME/.dcr/bin:$PATH"
```
### Windows (PowerShell)
```powershell
irm https://ps1.dcr-tool.ru | iex
# or download then run:
# irm https://ps1.dcr-tool.ru -OutFile dcrup.ps1
# powershell -File .\dcrup.ps1 self-install
# $env:Path += ";$env:USERPROFILE\.dcr\bin"
dcrup install stable
```
Optional cmd bootstrap (if you prefer `curl` of the cmd shim):
```bat
curl -fsSL -o dcrup.cmd https://cmd.dcr-tool.ru
```
After `self-install`, the command is **`dcrup`** (no `.sh` / `.ps1`): shims live in `~/.dcr/bin` (Unix) or `%USERPROFILE%\.dcr\bin` (Windows `dcrup.cmd`).
### Common dcrup commands
```sh
dcrup install stable # latest stable prebuilt (auto: cf → gh → sf → ya)
dcrup install 0.8.2 # pin → 0.8.2@stable
dcrup install 0.8.2@dev
dcrup install stable --libc musl # Linux: musl asset (default: gnu)
dcrup install stable --mirror cf # CloudFlare CDN
dcrup install stable --mirror ya # Yandex CDN (RU fallback)
dcrup install stable --build # cargo build --features archive
dcrup install night # always build from branch dev HEAD
dcrup default 0.8.2
dcrup update
dcrup list
dcrup show
dcrup which
```
Layout: `~/.dcr/toolchains/\<id>/dcr` and `~/.dcr/bin/dcr` → active version.
### Download mirrors
Prebuilt installs try **cf → gh → sf → ya** unless you pin a host.
| Code | URL | Notes |
| ---- | ------------------------------------------------------------------------------------------------------------ | -------------------------- |
| `cf` | `https://cdn-global.dcr-tool.ru/\<tag>/\<asset>` | CloudFlare CDN (worldwide) |
| `gh` | `https://github.com/dexoron/dcr/releases/download/\<tag>/\<asset>` | GitHub Releases |
| `sf` | `https://sourceforge.net/projects/dcr-tool/files/\<tag>/\<asset>/download` | SourceForge |
| `ya` | `https://cdn-ru.dcr-tool.ru/\<tag>/\<asset>` | Yandex CDN (RU fallback) |
```sh
dcrup install stable --mirror auto # default
export DCRUP_MIRROR=cf # persist for this shell
```
---
## Arch Linux (AUR)
```sh
yay -S dcr
```
## macOS / Linux (Homebrew)
```sh
brew tap dexoron/dexoron
brew install dcr
```
## Snap (Linux)
```sh
sudo snap install dcrup
```
> If classic Snap Store publishing is unavailable, install the `.snap` from [GitHub Releases](https://github.com/dexoron/dcr/releases/latest) with `--dangerous`.
## Nix (flake)
```sh
nix run github:dexoron/dcr
nix profile install github:dexoron/dcr
```
## Cargo (crates.io)
```sh
cargo install dcr
```
Note: crates.io builds may omit optional features. For FAT disk images (`[archive]`), prefer release binaries or:
```sh
cargo install dcr --features archive
```
## From source
```sh
git clone https://github.com/dexoron/dcr.git
cd dcr
cargo build --release --features archive
ln -sf "$PWD/target/release/dcr" ~/.local/bin/dcr
# or manage versions with dcrup install night / --build
```
## Post-install
```bash
dcr --version
dcrup show # if installed via dcrup
```
Man pages (package installs / release assets):
```bash
man dcr
man dcr-build
```
Registry (optional) — `~/.dcr/config.toml`:

Install the recommended [DCR extension by Dexoron-Labs](https://marketplace.visualstudio.com/items?itemName=Dexoron-Labs.dcr). Do not install Microsoft C/C++ extensions for DCR projects: DCR uses `clangd`. MS C/C++ is acceptable only when you need its debugger.
Recommended companion extensions:
* [Even Better TOML](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml)
* [CodeLLDB](https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb), or MS C/C++ for debugger support only
```bash
dcr gen vscode
```
Generates in `.vscode/`:
| File | Purpose |
| ----------------- | -------------------------------------------- |
| `tasks.json` | `build` task (dcr build) |
| `launch.json` | Debug launch configuration |
| `settings.json` | clangd/IntelliSense: include paths, standard |
| `extensions.json` | Recommends vscode-clangd, vscode-lldb |
## CLion
```bash
dcr gen clion
```
Generates in `.idea/`:
| File | Purpose |

| `externalTools.xml` | Build, Run, Clean, Test as external tools |
| `customTargets.xml` | Custom build targets |
| `misc.xml` | C/C++ project settings |
| `runConfigurations/\<name>.xml` | Per-binary run configurations |
## compile_commands.json
```bash
dcr gen compile-commands
```
Generates `compile_commands.json` at project root. Standard format for clangd, C/C++ IntelliSense, static analyzers.
## project-info
```bash
dcr gen project-info
```
Outputs JSON array with project metadata (see [gen-commands](/docs/commands/gen-commands)).

# Library Project
Creating a static library and using it in another project.
## Step 1: Create the library
```bash
dcr new my-lib
cd my-lib
```
`dcr.toml`:
```toml
[package]
name = "my-lib"
version = "0.1.0"
type = "none"
[build]
language = "c"
standard = "c11"
kind = "staticlib"
```
`src/my_lib.h`:
```c
#ifndef MY_LIB_H
#define MY_LIB_H
int add(int a, int b);
#endif
```
`src/my_lib.c`:
```c
#include "my_lib.h"
int add(int a, int b) { return a + b; }
```
## Step 2: Build
```bash
dcr build --release
```
Artifacts:
* `target/\<triple>/release/libmy-lib.a` (Linux)
* `target/release/my-lib.lib` (Windows)
* `target/include/` — header files
## Step 3: Use in another project
```bash
dcr new my-app
cd my-app
dcr add my-lib ../my-lib
```
Automatically:
* Adds include path to `target/include/` of the library
* Adds lib path to `target/\<triple>/release/`
* Links `libmy-lib.a` / `my-lib.lib`

# Pure ASM / boot image (flat-bin + archive)
Minimal OS-dev style pipeline: assemble raw binaries with NASM, then pack a FAT floppy/image with an optional boot sector.
## Project layout
```
myos/
dcr.toml
src/
boot.asm # boot sector (512 bytes)
kernel.asm # payload
```
For multiple flat artifacts, use a **workspace** (one member per binary) or separate packages; a single `flat-bin` package produces one binary per source stem.
## Boot package (`flat-bin`)
```toml
[package]
name = "boot"
version = "0.1.0"
[build]
language = "asm"
compiler = "nasm"
kind = "flat-bin"
extension = "bin"
roots = ["src/boot.asm"]
```
```bash
dcr build
# → target/<…>/debug/boot.bin (NASM -f bin, no link)
```
## Disk image after build
```toml
[archive]
output = "target/{profile}/disk.img"
format = "fat12"
size = "1440K"
label = "MYOS"
bootsector = "target/{profile}/boot.bin"
[[archive.layout]]
from = "target/{profile}/kernel.bin"
to = "KERNEL.BIN"
```
* `format`: `fat12`, `fat16`, or `fat32`
* `size`: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default ~1.44 MiB)
* `bootsector`: written only when `offset` is omitted or `0`
* `from` may be a glob; `{profile}` is substituted in paths
## C kernel → flat binary
```toml
[build]
language = "c"
compiler = "clang"
kind = "flat-bin"
freestanding = true
filename = "kernel"
extension = "bin"
ldflags = ["-T", "linker.ld"]
```
Pipeline: objects → temporary linked ELF → `objcopy -O binary` → `kernel.bin`. Requires `objcopy` / `llvm-objcopy` in PATH.
## Other assemblers
| Tool | Notes |
| -------- | --------------------------------------------------------------------------------------- |
| **FASM** | Write `format binary` in the source; DCR writes `\<stem>.bin` directly |
| **GAS** | Assemble `.s` → obj → `objcopy -O binary` |
| **LLC** | `language = "llvm_ir"` → obj → objcopy |
| **MASM** | COFF obj → objcopy (needs binutils/LLVM objcopy) |
## Notes
* Single-file `roots` are supported: `roots = ["src/boot.asm"]`.
* `--force` re-runs `build.steps` / `build.post_steps` as well as recompilation.
* Prefer `kind = "elf"` if you need a relocatable ELF kernel without stripping to raw binary.

sidebar_label: Build profiles

# Build Profiles
Profiles allow overriding `[build]` fields for specific build modes.
## Configuration
```toml
[build]
language = "c"
standard = "c17"
cflags = ["-Wall"]
[build.debug]
cflags = ["-O0", "-g"]
[build.release]
cflags = ["-O3", "-DNDEBUG"]
```
## Merge rules
Fields from `[build.\<profile>]` are merged on top of `[build]`:
* **Scalar fields** (strings, numbers, bools) — replaced
* **Arrays** (`cflags`, `ldflags`, ...) — **appended** (extend the `[build]` array)
Set `inherit = false` to disable array inheritance (only profile's own arrays are used).
## Built-in profiles
The default flags for each profile are composed from three config fields:
| Field | debug default | release default |
| ----------- | ------------------ | --------------- |
| `opt_level` | `"0"` | `"3"` |
| `debug` | `true` | `false` |
| `warnings` | `["all", "extra"]` | `[]` |
Which produce the equivalent compiler flags:
| Profile | Effective flags |
| --------- | ---------------------------------------------------------- |
| `debug` | `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG` |
| `release` | `-O3 -DNDEBUG` |
Additional build options can be toggled per-profile:
```toml
[build.release]
opt_level = "z"
lto = true
strip = true
panic = "abort"
codegen-units = "1"
[build.debug]
opt_level = "1"
debug = false
warnings = ["all", "error"]
```
## Target-specific profiles
```toml
[build.linux]
cflags = ["-DLINUX"]
[build.windows.debug]
cflags = ["-DWIN32", "-O0", "-g"]
```
Application order (highest priority first):
1. `[build.\<target>.\<profile>]`
2. `[build.\<profile>.\<target>]`
3. `[build.\<target>]`
4. `[build.\<profile>]`
5. `[build]`

# Build System
## Compiler Backends
DCR supports 7 compilation backends. Selection is automatic based on file extension and `build.compiler` value.
| Backend | Files | When used |
| --------- | --------------------------------- | ------------------------------------- |
| `unix_cc` | `.c`, `.cpp`, `.cxx`, `.cc`, `.S` | gcc/clang on Linux/macOS/BSD |
| `msvc` | `.c`, `.cpp`, `.cxx`, `.cc` | Windows (cl, clang-cl) |
| `gas` | `.s` | ARM/ARM64 assembler (no preprocessor) |
| `nasm` | `.asm`, `.s` | x86/x86_64 NASM assembler |
| `masm` | `.asm` | MASM (ml/ml64) on Windows |
| `fasm` | `.asm`, `.fasm` | Flat Assembler |
| `llvm_ir` | `.ll` | LLVM IR via `llc -filetype=obj` |
## Qt Support
DCR provides native Qt support for automatic meta-object handling (MOC, UIC, RCC).
Enable it by setting `build.qt = true` in `dcr.toml`. DCR will automatically detect Qt-related files (`.ui`, `.qrc`, `.h` with `Q_OBJECT`) and process them.
```toml
[build]
qt = true
```
*Note: Requires `qt6` modules (Core, Widgets, Gui, Svg) installed via `pkg-config`.*
Advanced customization is still possible via `build.steps` if special handling is needed:
```toml
[build.steps]
moc = "moc {in} -o {out}"
```
### Unix CC
* Compiler resolved via `resolve_compiler()`: `DCR_COMPILER` > `DCR_CC` > `[toolchain]` > `build.compiler` > `PATH`
* Supports `.d` files for header dependency tracking
* Flags: `-std=`, `-MMD -MF`, `-c -o`, `-I`, `-L`, `-l`
* Conditional flags based on config:
* `freestanding` or bare-metal target: `-ffreestanding` (compile), `-nostdlib -static` (link)
* `lto`: `-flto` (compile + link)
* `panic = "abort"`: `-fno-exceptions` (C++ only), `-fno-unwind-tables`, `-fno-asynchronous-unwind-tables`
### MSVC
* Supports cl.exe and clang-cl.exe
* Flags: `/std:`, `/Fo:`, `/Fe:`, `/I`, `/link`
### GAS / NASM / MASM / FASM / LLVM-IR
* GAS: `-I`, `-c -o`, `--defsym`
* NASM: `-I`, `-o`, `-D`, `-f` (format: win64/elf64/macho64/macho32/elf32; **`bin` when `kind = "flat-bin"`**)
* MASM: `/nologo /c /Fo\<obj> <source>`
* FASM: `<source> \<output>` (output path is the object file)
* LLVM IR: `-filetype=obj <source> -o \<output>`
## Incremental Builds
Three levels of incrementality:
1. **mtime** — if output is newer than all inputs, skip
2. **`.d` files** — header change tracking (including transitive)
3. **SHA256 fingerprint** — recompile if compiler flags changed (stored in `.dcr_fingerprint`)
## Parallel Compilation
* `thread::scope` for thread pool
* Atomic task queue (`AtomicU64`)
* Mutex on stdout (`OUTPUT_MUTEX`)
* Thread count = `available_parallelism()`, capped by `build.codegen-units` if set
## Build Kinds
| Kind | Type | Path (Linux example) |
| ----------- | ------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| `bin` | Executable | `target/\<triple>/\<profile>/\<name>` (.exe on Windows) |
| `staticlib` | Static library | `target/\<triple>/\<profile>/lib\<name>.a` (.lib) |
| `sharedlib` | Dynamic library | `target/\<triple>/\<profile>/lib\<name>.so` (.dll/.dylib) |
| `efi` | UEFI application | `target/\<triple>/\<profile>/\<name>.efi` |
| `elf` | ELF without stdlib | `target/\<triple>/\<profile>/\<name>` |
| `none` | Compile only, no link | — |
| `custom` | Full filename+extension control | `target/\<triple>/\<profile>/\<filename>.\<extension>` |
| `flat-bin` | Raw binary | ASM: `\<stem>.bin` (NASM `-f bin` / FASM / GAS·MASM·LLC via objcopy); C/C++: `\<name>.bin` (link + objcopy) |
## Disk images (`[archive]`)
After a successful build, if `[archive]` is present in `dcr.toml`, DCR formats a FAT volume and copies files from `layout` into the image. See [dcr.toml → archive](/docs/reference/dcr-toml#archive).
## Build Steps
DCR supports pre-build and post-build steps:
* `build.steps` — commands before compilation
* `build.post_steps` — commands after compilation
Substitutions: `{stem}`, `{in}`, `{out}`, `{profile}`, `{version}`, `{name}`.
Example Qt codegen via build steps:
```toml
[build.steps]
moc = "moc {in} -o {out}"
```
## pkg-config
Automatic lookup (read from raw config):
```toml
[build]
pkg_config = ["sdl2", "gl"]
```
DCR runs `pkg-config --cflags sdl2 gl` and `pkg-config --libs sdl2 gl` and adds results to compiler/linker flags.
## Variable Substitution
Supported variables:
| Variable | Description |
| ----------------------- | ---------------------------- |
| `{version}` | Package version |
| `{version_major}` | Major version part |
| `{version_minor}` | Minor version part |
| `{version_patch}` | Patch version |
| `{version_suffix}` | Suffix (e.g., `-rc1`) |
| `{version_suffix_dash}` | Suffix with dash |
| `{profile}` | Profile name (debug/release) |
| `{name}` | Package name |

# Cross-Compilation
## Short Names
DCR supports short platform names:
| Short Name | Full Triple |
| ---------- | -------------------------- |
| `linux` | `x86_64-unknown-linux-gnu` |
| `macos` | `x86_64-apple-darwin` |
| `windows` | `x86_64-pc-windows-msvc` |
```bash
dcr build --target windows
```
## Full Triples
```bash
dcr build --target aarch64-unknown-linux-gnu
dcr build --target x86_64-pc-windows-gnu # mingw
dcr build --target armv7-unknown-linux-gnueabihf
```
## clang --target
When using clang, DCR injects `--target=\<triple>` into CFLAGS.
```toml
[build]
compiler = "clang"
target = "aarch64-unknown-linux-gnu"
# Auto: cflags += ["--target=aarch64-unknown-linux-gnu"]
```
## Bare-Metal / Freestanding
For targets containing `none`, `-elf`, `eabi`, or `baremetal`, DCR automatically:
1. **Disables default flags** — no system include paths, no `-l` libc
2. **Injects `-ffreestanding`** at compile time and `-nostdlib -static` at link time
You can also enable freestanding mode explicitly:
```toml
[build]
freestanding = true
```
```bash
dcr build --target aarch64-none-elf
```
## Target Directory
By default, the compilation output directories are structured as follows:
* **Linux and BSD**: Always output to `target/\<triple>/\<profile>/` (using host triple if no target is specified).
* **macOS and Windows (without target)**: Output to `target/\<profile>/`.
* **macOS and Windows (with explicit target)**: Output to `target/\<triple>/\<profile>/`.

| `qt` | `false` | Enable automatic Qt meta-object handling (MOC, UIC, RCC) |
Settings from raw config (not in typed struct):
* `pkg_config` — list of packages queried for build-wide compiler/linker flags
Dependencies can also declare a system package directly, for example
`fmt = { pkg-config = "fmt" }`. This records the package in `dcr.lock` and applies
the flags returned by `pkg-config --cflags` and `pkg-config --libs`.
* `ldscript` — linker script path
* `build.steps` / `build.post_steps` — codegen steps
## Per-language overrides: `[build.c]`, `[build.cxx]`, `[build.asm]`, `[build.llvm_ir]`
Each language can have its own table that overrides the flat `[build]` settings:
```toml
[build]
compiler = "clang"
standard = "c11"
[build.c]
standard = "c23"
compiler = "gcc"
[build.cxx]
standard = "c++23"
compiler = "g++"
[build.asm]
compiler = "nasm"
flags = ["-felf64"]
[build.llvm_ir]
compiler = "llc"
```
The flat `[build]` acts as fallback; per-language tables take precedence for their language.
Example:
```toml
[build]
language = "c++"
standard = "c23"
cxx_standard = "c++23"
compiler = "clang"
kind = "sharedlib"
cflags = ["-Wall", "-Wextra"]
opt_level = "z"
lto = true
strip = true
panic = "abort"
codegen-units = "2"
```
## [toolchain]
```toml
[toolchain]
cc = "/usr/bin/clang"
cxx = "/usr/bin/clang++"
as = "/usr/bin/as"
ar = "/usr/bin/ar"
ld = "/usr/bin/ld.lld"
```
Raw config also supports `uic`, `moc`, `rcc` for Qt codegen.
## [dependencies]
See [dependencies](/docs/reference/dependencies).
## [run]
```toml
[run]
cmd = "./target/{profile}/{name}"
```
Substitutions:
* `{version}` — package version
* `{version_major}`, `{version_minor}`, `{version_patch}`, `{version_suffix}`, `{version_suffix_dash}` — version parts
* `{profile}` — debug / release
* `{name}` — package name
Default `cmd` = `./target/{profile}/{name}` (macOS/Windows) or `./target/\<triple>/\<profile>/\<name>` (Linux).
## [workspace]
See [workspaces](/docs/reference/workspaces).
## [archive]
Optional post-build step: format a FAT volume and copy built artifacts into a disk image. Runs after a successful package build (and after workspace member builds that define `[archive]`).
Requires DCR built with the `archive` Cargo feature (`cargo build --features archive`). Release binaries include this feature.
| Field | Required | Description |
| ------------ | -------- | ------------------------------------------------------------------------------------------- |
| `output` | yes | Image path relative to project root (`{profile}` allowed) |
| `format` | yes | `fat12`, `fat16`, or `fat32` |
| `size` | no | Image size: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default `1474560` ≈ 1.44 MiB) |
| `offset` | no | Byte offset of the FAT volume inside the image (default `0`) |
| `label` | no | Volume label (max 11 chars, default `VOLUME`) |
| `bootsector` | no | Path to a 512-byte boot sector written at offset 0 when `offset` is 0 (`{profile}` allowed) |
| `layout` | no | List of `{ from, to }` entries (files or globs → path inside the volume) |
```toml
[archive]
output = "target/{profile}/disk.img"
format = "fat12"
size = "1440K"
label = "MYOS"
bootsector = "target/{profile}/boot.bin"
[[archive.layout]]
from = "target/{profile}/kernel.bin"
to = "KERNEL.BIN"
[[archive.layout]]
from = "assets/*"
to = "/"
```
Typical pairing with `kind = "flat-bin"` (NASM `-f bin`) for bootloaders and pure-ASM OS images.
## `flat-bin` (kind)
Produces a raw binary (default extension `bin`) for boot sectors, kernels, and freestanding payloads.
### Assemblers
| Tool | Language / compiler | How flat-bin is produced |
| ---- | ------------------------------------------ | -------------------------------------------- |
| NASM | `language = "asm"`, `compiler = "nasm"` | `-f bin` → `\<stem>.bin` |
| FASM | `compiler = "fasm"` | direct write (use `format binary` in source) |
| GAS | `compiler = "as"` / `"gas"` | assemble → `objcopy -O binary` |
| MASM | `compiler = "ml"` / `"ml64"` | assemble → `objcopy -O binary` |
| LLC | `language = "llvm_ir"`, `compiler = "llc"` | `-filetype=obj` → `objcopy -O binary` |
```toml
[build]
language = "asm"
compiler = "nasm"
kind = "flat-bin"
extension = "bin"
roots = ["src/boot.asm"]
```
### C / C++
Compile all sources, link with `-nostdlib -static` (plus your `ldflags` / `ldscript`), then convert the intermediate ELF/PE with `objcopy -O binary` to `\<filename|name>.bin`.
```toml
[build]
language = "c"
compiler = "clang"
kind = "flat-bin"
freestanding = true
filename = "kernel"
extension = "bin"
ldscript = "linker.ld"
ldflags = ["-T", "linker.ld"]
```
Notes:
* Multi-file **ASM** packages emit one `\<stem>.bin` per source; **C/C++** emit a single project binary.
* `objcopy` tools tried in order: `llvm-objcopy`, `objcopy`, `gobjcopy`.
* Incompatible with `build.qt = true`.
* `dcr run` rejects `flat-bin` (not a host executable).

# Dependencies
## Formats
The `[dependencies]` section supports registry, path, Git, and `pkg-config` dependencies:
### String (registry)
```toml
[dependencies]
fmt = "10.1.1"
spdlog = "1.12"
catch2 = "3.4.0"
```
The version string is used as-is for registry lookup.
### Table (git)
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0" }
```
Fields: `git`, `branch`, `tag`, `rev`, `mode`, `include`, `lib`, `libs`.
### Table (path)
```toml
[dependencies]
mylib = { path = "../mylib" }
```
For a prebuilt external library, specify its layout explicitly. The three
arrays are paths relative to the dependency root (`include`, `lib`) and linker
names (`libs`):
```toml
[dependencies]
dcr-math = { path = "../deps/dcr-math", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
### Table (`pkg-config`)
Use an installed `.pc` package when the library is provided by the operating system
or another system package manager. DCR invokes `pkg-config --cflags` and
`pkg-config --libs`, preserving include, library, linker, and other flags:
```toml
[dependencies]
fmt = { pkg-config = "fmt" }
openssl = { pkg-config = ["openssl", "libcrypto"] }
```
The `pkg-config` executable must be available in `PATH`. The named `.pc` files must
be available through pkg-config's standard search paths or via `PKG_CONFIG_PATH`.
These dependencies are not downloaded or built by DCR; they are recorded in
`dcr.lock` with a `pkg-config+...` source.
## Registry
DCR uses a package registry for dependency lookup by name.
```toml
# ~/.dcr/config.toml
[registry.default]
url = "https://index.dcr.dexoron.tech"
priority = 1
```
Registry priority: order in `config.toml`. The `DCR_INDEX_PATH` variable overrides the path to `index.json`.
## Git dependencies
Git dependencies are cloned into `~/.dcr/git/`; their exact checked-out commit is written to `dcr.lock`.
Both Git and path dependencies have two modes:
* **DCR package:** the source has `dcr.toml`. DCR builds it before the consumer and uses the package name from its manifest for linking.
* **Prebuilt library:** it provides existing headers and binaries through `include`, `lib`, and `libs`. DCR passes them to the compiler/linker without building the dependency.
The mode is normally detected automatically. Use `mode = "build"` or `mode = "prebuild"` when a source contains both a manifest and prebuilt artifacts and you need to choose explicitly.
`dcr-math-lib` publishes both forms. Select its prebuilt library explicitly:
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0", mode = "prebuild", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
DCR supports specifying branch/tag/rev for git sources:
* `branch` — switch to a branch
* `tag` — switch to a tag
* `rev` — switch to a specific commit
* `features` — feature flags (parsed, but does not affect build)
## Path dependencies
Local paths may point at a DCR package or a prebuilt external library. A path DCR package is built before its consumer, including its own path/git dependencies. DCR detects dependency cycles. A prebuilt library is never built by DCR; it is linked from the directories declared in its dependency entry.
```toml
[dependencies]
mylib = { path = "/abs/path/to/lib" }
mylib = { path = "../relative/path" }
```
For DCR packages, the package name from `dcr.toml` is used for linking (so the dependency key may differ from the library name). Header resolution includes the packaged `target/include` directory and link search includes `target/lib`.
### Recommended library layouts
Buildable DCR library:
```text
dcr-math-lib/
├── dcr.toml
└── src/
├── dcr_math.c
└── dcr_math.h
```
Prebuilt library:
```text
dcr-math-lib/
├── include/
│ └── dcr_math.h
└── lib/
└── libdcr-math.a # or .so / .lib
```
`libs` contains linker names without the `lib` prefix and file extension: use
`["dcr-math"]` for `libdcr-math.a`.
If one repository contains both forms, keep the prebuilt files in `include/` and `lib/` and select the mode explicitly:
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0", mode = "prebuild", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
For a local copy, replace `git` with `path = "../dcr-math-lib"`. In `prebuild` mode DCR does not run the dependency build, even when `dcr.toml` is present.
## dcr.lock
Dependency lock file. Contains package names and sources.
Created during `dcr build` for resolved registry, path, and Git dependencies. Not updated during `dcr add` — only on the next `dcr build`.
## Resolution process
1. Resolve dependency sources (registry → git → path)
2. Fetch git dependencies into `~/.dcr/git/` and check out the requested ref
3. Build DCR package dependencies recursively
4. Collect `include_dirs`, `lib_dirs`, `libs` for the compiler

# Environment Variables
## DCR_COMPILER
Overrides the compiler for all languages. **Highest priority.**
```bash
export DCR_COMPILER=clang
dcr build
```
Compiler resolution priority:
1. `DCR_COMPILER` (env)
2. `DCR_CC` / `DCR_CXX` / `DCR_AS` (env)

# Platform Support
## Target Triples
DCR normalizes target triples. Short platform names are expanded to full triples.
### Linux
```
target/<arch>-unknown-linux-<env>/<profile>/
```
Architectures: `x86_64`, `aarch64`, `i686`, `armv7`, `riscv64` (host-detected).
Environments: `gnu` (default), `musl`.
Artifact type: ELF. Extensions: `.so` (sharedlib), `.a` (staticlib).
### macOS
```
target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
```
Architectures: `x86_64`, `aarch64` (host-detected).
Extensions: `.dylib` (sharedlib), `.a` (staticlib).
### Windows
```
target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
```
Architectures: `x86_64`, `aarch64`.
Environments: `msvc` (default), `gnu` (MinGW).
Extensions: `.exe` (bin), `.lib` (staticlib), `.dll` (sharedlib), `.efi` (UEFI).
### BSD
```
target/<arch>-unknown-<os>/<profile>/
```
Supported systems: `freebsd`, `openbsd`, `netbsd`, `dragonfly`.
## Host Detection
DCR uses `std::env::consts::ARCH` and `std::env::consts::OS` for host platform detection. Used as fallback when `target` is not specified.

# Workspaces
Workspaces allow managing multiple packages in a single repository.
## Configuration
```toml
[workspace.lib-core]
path = "lib-core"
[workspace.lib-utils]
path = "lib-utils"
deps = ["lib-core"]
[workspace.app]
path = "app"
deps = ["lib-core", "lib-utils"]
main = true
```
### Member fields
| Field | Description |
| ------ | ------------------------------------------------ |
| `path` | Path to the package (relative to workspace root) |
| `deps` | Dependencies on other members |
| `main` | Mark as the main package |
## Topological sort
DCR automatically sorts packages by dependencies: package A is built before B if B depends on A.
Cyclic dependencies are detected and cause an error.
## Build
```bash
dcr build # build all packages in dependency order
dcr build --workspace app # build only app (dependencies built automatically)
```
When building a workspace, DCR automatically injects include and library paths of dependent workspace members:
* **Include Paths**: Automatically resolves and injects header directories of dependencies, including the member's `src/` directory, local `include/` directory, and the packaged `target/include` directory.
* **Library Paths**: Injects compiled library search paths (`target/lib` as well as target-specific build folders) to allow automatic linking with member libraries.
## Clean
```bash
dcr clean # clean only root target/
dcr clean --all # clean target/ of all packages
```
## Inheritance
If a member has `inherit = true` in its `[build]` section, fields from the root `[build]` are merged into the member:
```toml
# root dcr.toml
[build]
inherit = true
language = "c"
standard = "c17"
# member inherits language and standard
```
## Workspace-only root (no build of its own)
A workspace root can set `workspace_only = true` — it won't be built itself, and doesn't need `language` or `compiler`:
```toml
[package]
name = "my-workspace"
version = "0.1.0"
[build]
workspace_only = true
kind = "bin"
[workspace]
lib-core = { path = "lib-core" }
app = { path = "app", deps = ["lib-core"] }
```

sidebar_label: Self Update
---
# Self Update
## dcr --update
Automatic update to the latest version. Downloads a binary (not an archive) from GitHub Releases and replaces the current executable.
```bash
dcr --update
```
## How it works
1. DCR detects the current platform and architecture
2. Fetches the latest release from `api.github.com/repos/dexoron/dcr/releases/latest`
3. Compares versions
4. Downloads the matching asset (direct binary URL, not archive)
5. Replaces the current executable via `self_replace`
## Asset naming
Pattern: `dcr-\<triple>` or `dcr-\<triple>.exe`
| Platform | Asset name |
| -------------- | -------------------------------- |
| Linux x86_64 | `dcr-x86_64-unknown-linux-gnu` |
| macOS x86_64 | `dcr-x86_64-apple-darwin` |
| macOS ARM64 | `dcr-aarch64-apple-darwin` |
| Windows x86_64 | `dcr-x86_64-pc-windows-msvc.exe` |
## AUR
If DCR was installed via AUR, `--update` shows a warning:
```
Update via package manager: yay/paru -Syu {package_name} or sudo pacman -Syu {package_name}
```
## Errors
* Cannot detect platform — error
* Cannot fetch release — error with URL
* No write permission — error (use `sudo` or manual install)

# Test Framework
DCR has a built-in minimal test framework for C.
## Macros
### `EXPECT(expr)`
Asserts that an expression is true.
```c
EXPECT(1 + 1 == 2);
EXPECT(ptr != NULL);
```
### `SKIP(reason)`
Skips a test with a message.
```c
SKIP("not implemented on Windows");
```
### `TEST(name)`
Defines a test.
```c
TEST(addition) {
EXPECT(1 + 1 == 2);
EXPECT(2 + 2 == 4);
}
```
### `TEST_CASE(name)`
Registers a test case.
```c
TEST_CASE(math) {
EXPECT(1 + 1 == 2);
}
```
## Initialization
```bash
dcr test --init
```
Creates:
* `tests/dcr_test.h` — framework header (do not edit)
* `tests/test.c` — template with example test
## Structure
```
tests/
├── dcr_test.h # framework (do not edit)
├── test.c # main tests
└── ... # additional .c test files
```
Only `.c` files are compiled (`.cpp` is not supported).

# Список изменений
## 0.9.1 (2026-09-13)
* **`pkg-config` dependencies** — declare `fmt = { pkg-config = "fmt" }` or multiple package names in `[dependencies]`; DCR applies `.pc` compiler/linker flags and records the resolved package in `dcr.lock`.
* **`dcr add` support for `pkg-config`** — easily add system package dependencies with `dcr add fmt pkg-config:fmt` or `dcr add openssl pkg:openssl,libcrypto`.
* **`dcr tree` & IDE integration** — `pkg-config` packages are marked in `dcr tree` and resolved into compiler flags in `dcr gen` (`compile_commands.json`).
* **Fixed `dcr new` in non-ASCII / spaced paths** — initializing projects from folders with non-ASCII characters or spaces no longer fails validation.
## 0.9.0 (2026-08-31)
* **Download mirrors in `dcrup`** — `--mirror auto|cf|gh|sf|ya` and `DCRUP_MIRROR`.
Default `auto` tries **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
* **Complete Path/Git dependencies** — DCR packages from `path` and `git` are built before their consumer. Git sources are cached in `~/.dcr/git`, support `branch`/`tag`/`rev`, and record the exact commit in `dcr.lock`.
* **Build and prebuild modes** — `path` and `git` dependencies can build a DCR package from `dcr.toml` or link existing `include`/`lib`/`libs` artifacts; `mode = "build"` / `"prebuild"` selects explicitly when both forms are present.
* **Prebuilt dependency examples** — documentation now shows the `dcr-math-lib` Git repository and recommended build/prebuilt layouts for both `git` and `path`.
* **Transitive dependency builds and cycle reporting** — DCR recursively builds DCR packages and reports a clear dependency chain for cycles.
* **Bare path arguments for `dcr add`** — `dcr add mylib ../mylib` now works in addition to the explicit `path:` form.
* **Removed `install.sh` / `install.ps1` / `install_bsd.sh`** — superseded by `dcrup`.
## 0.8.5 (2026-08-08)
* **`package.dcr-version`** — optional CLI version pin in `dcr.toml`.
`dcr new` / `dcr init` write the current version. On config load:
* missing / empty pin → warn "add dcr-version";
* dcr older than pin → warn "update dcr";
* dcr newer than pin → warn "check changelog, update pin";
* equal → silent.
Commands do not fail, warning only (once per path per process).
## 0.8.4 (2026-08-04)
**Added:**
* **`.dcr/` directory** — shared machine-readable build facts for IDE integrations:
* `.dcr/compile_commands.json`
* `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
* `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
* `.dcr/ide/` (placeholder for IDE lock files)
* **`dcr gen project-info`** — `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; absolute/canonical paths.
* **`dcr build --print-artifact-path`** — one absolute artifact path line on stdout after a successful build.
* **`dcr gen … --quiet` / `-q`** — suppress human success logs for gen subcommands.
* **`.clangd`** — created on first gen with `CompilationDatabase: .dcr` (`# managed by dcr gen`); custom `.clangd` is not overwritten.
* **Helpers** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` via `platform::*`.
* **`dcr new` / `dcr init`** — add `.dcr/` to `.gitignore`.
**Changed (breaking):**
* **`compile_commands.json` moved** from project root to **`.dcr/compile_commands.json`**.\
clangd discovers it via `.clangd` / `--compile-commands-dir=.dcr`.\
CLion and VSCode generators updated accordingly.
* **Atomic write** for compile_commands (tmp + rename).
* **`gen vscode` / `gen clion` launch/run** — use the same artifact path resolver as `project-info` / `build-info.json`.
**Fixed:**
* Launch configs no longer hardcode `target/\<profile>/\<name>` without the Linux triple segment.
* Symlink/mount roots: best-effort canonicalize for root and compile database paths.
## 0.8.3 (2026-08-03)
### Добавлено:
* **`dcr run -- \<args>...`** — cargo-style argument forwarding after a bare `--`\
(`dcr run --release -- --test_help`). Applies to direct binary runs and `[run].cmd`.
* **Tests** — host target section `ldflags` without CLI `--target`; run-arg forwarding; `split_double_dash` unit tests.
### Изменено:
* **Native builds resolve the host triple** — without `--target` / package `build.target`, host sections such as\
`[build.x86_64-unknown-linux-gnu]` apply again (`cflags` / `ldflags` / toolchain).\
Previously the target was empty and those sections were ignored while artifacts already used the host triple path.
* **Empty target** — no more `Unknown target ''` warning.
* **`dcr run --help` / man `dcr-run`** — document `--` forwarding.
### Исправлено:
* **Native artifact paths on Windows and macOS** — without an explicit `--target` / `build.target`, artifacts use `target/\<profile>`, so `dcr run` and flat-bin find the build output.
* Target-specific `ldflags` missing on native host builds (e.g. micro-lang + `libsct-elf`).
* Spurious empty-target warning.
## 0.8.2 (2026-07-22)
### Добавлено
* **Compile progress `[N/M]`** — live TTY status line (`compile pkg v0.1.0 [12/41]`) so long mono-package builds do not look hung.
* **DCR status style** — fixed-width verbs: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run`.
* **Cargo feature `archive`** — optional FAT packing via `fatfs` (`cargo build --features archive`). Release CI builds with the feature; without it `[archive]` fails with a clear message.
* **Tests** — `flat_bin_nasm_build`, package `build.target` without CLI `--target`, stricter workspace `clean --all`.
* **CI expansion** — unit + integration on Linux/macOS/Windows, archive feature job, rust-cache, clippy default + all-features (see `.github/workflows/ci.yml`).
### Изменено
* **No forced host triple from CLI** — without `--target`, package/member `build.target` is honored (bare-metal / ISO `post_steps` paths).
* **Relative include/lib flags** (`-I`, `-i`, `-isystem`, `-idirafter`, `-L`, `-T`) absolutized against the package root under workspace builds.
* **`dcr clean --all`** — no spam for members without a local `target/` (shared root `target/`).
* **`error` / `warn`** — red / yellow on stderr; CLI fully English (`Hint:`).
* **Help / man** — list `add`, `lint`, `setup`; unknown command exits with code 1.
* **Tool NotFound** — `linker not found: ld.lld …` / `{tool} not found …` instead of raw `os error 2`.
## 0.8.1 (2026-07-20)
### Added
* **`build.kind = "flat-bin"`** — raw binary (default `.bin`) for OS-dev payloads:
* **NASM** — `-f bin` → `\<stem>.bin`
* **FASM** — direct output (`format binary` in source)
* **GAS / MASM / LLC** — object → `objcopy -O binary` → `\<stem>.bin`
* **C/C++** — objects → freestanding link → `objcopy -O binary` → `\<name>.bin`
* Requires `llvm-objcopy` / `objcopy` / `gobjcopy` except for NASM/FASM direct emit
* **`[archive]` section** — FAT12/16/32 disk images after build (`output`, `format`, `size`, `offset`, `label`, `bootsector`, `layout`). From 0.8.2 requires feature `archive`.
* **Single-file `build.roots`** — a root may be a single source or header file, not only a directory.
### Changed
* **`--force`** also re-runs `build.steps` and `build.post_steps`.
* **`dcr run` on workspace-only root** — if `[run].cmd` is set, run that after build; otherwise delegate to a workspace member.
## 0.8.0 (2026-07-18)
### Added
* **Dedicated Build Engine (`src/core/build/engine.rs`)** — decoupled the build orchestration logic completely from the CLI front-end wrapper in `src/cli/build.rs` to a reusable, decoupled core build engine.
* **Polymorphic Language Model (`Language` trait)** — introduced the abstract `Language` trait (`src/core/build/language/mod.rs`). File scanning, compiler resolution, and flags handling are now encapsulated in dedicated language modules for C, C++ (including Qt code generation), LLVM IR, and ASM (GAS, NASM, FASM, MASM).
* **Polymorphic Compilation Dispatch (`Builder` trait)** — introduced the `Builder` trait to generalize builder invocations (`src/core/build/builder/mod.rs`). Consolidated GCC/Clang logic into `builder/cc_common.rs` and Microsoft Visual C++ logic into `builder/msvc/`.
* **Per-Language Configuration overrides (`[build.\<lang>]`)** — introduced support for configuring language-specific compiler, standard, and flags (e.g. `[build.c]`, `[build.cxx]`, `[build.asm]`) independently in `dcr.toml`.
* **Automatic Workspace Dependency Injection** — during workspace builds, include/lib paths of dependent workspace members (including their source headers, local `include/` folders, and build target `target/include` / `target/lib` folders) are automatically resolved and injected.
* **`BuildReporter` Event System** — decoupled build orchestration output into a structured event-driven reporter model (`src/core/build/report.rs`), making DCR suitable for library embedding and IDE integrations without stderr capturing.
* **Build Cancellation Support** — introduced thread-safe cancellation tokens (`Arc\<AtomicBool>`) allowing clients to safely abort compile runs mid-execution.
* **TOML Formatting & Custom Keys Preservation** — migrated the config editor to `toml_edit`, preserving all unknown/user-defined TOML keys, structures, and comments during file write operations (e.g., in `dcr add`).
* **Path Dependencies Target Include Resolution** — local path dependencies configured via tables now correctly expose headers built and packaged into their `target/include` folder to consumer packages.
* **Modular Integration Test Suite** — refactored the monolith `tests/cli_basic.rs` file into clean, specialized integration tests: `cli_build.rs`, `cli_deps.rs`, `cli_lint.rs`, `cli_new.rs`, `cli_qt.rs`, `cli_test.rs`, `cli_workspace.rs`.
### Changed
* **Consolidated Linking and Archiving** — artifact generation (linking executables/shared libraries and archiving static libraries) consolidated into a single `src/core/build/builder/artifact.rs` module.
* **Workspace-Aware member execution** — `dcr run` executed at the workspace root of a `workspace_only` project now triggers the member build inside the workspace context using the `--workspace` parameter, preventing standalone build issues.
* **Elimination of Global State** — removed global variables and states from the build core, encapsulating build logic inside isolated `BuildContext` structs for thread safety.
* **Build Cache Separation** — relocated mtime tracking, incremental caching, and header-dependency checking logic to `src/core/build/cache.rs`.
* **Modularized Pre-build Steps** — decoupled generator scripts and pre-build commands parsing into `src/core/build/steps.rs`.
## 0.7.4 (2026-06-17)
### Added
* **Native Qt support** — automatic meta-object handling (MOC, UIC, RCC) added when `build.qt = true` is set in `dcr.toml`.
* **`dcr lint` command** — C/C++ static analysis via `clang-tidy`. Supports `--fix` for automatic fixes. Respects `build.roots` and `build.src_disable` from config.
* **Three new assembler backends**:
* **MASM** (`compiler = "ml"` / `"ml64"`) — Microsoft Macro Assembler.
* **FASM** (`compiler = "fasm"`) — Flat Assembler.
* **LLVM IR** (`compiler = "llc"`) — compiles `.ll` files via `llc -filetype=obj`.
* **Shared ASM pipeline** — linking and archiving logic consolidated into `core/builder/asm.rs`. Adding a new assembler backend now takes ~30 lines.
* **Filesystem utilities** — `to_hex()` and `home_dir()` extracted to `utils/fs.rs`.
* **Build utilities** — `normalize_target()`, `normalize_kind()`, `normalize_platform()`, `default_profile_flags()` extracted to `utils/build.rs`.
* **Backend helpers** — `asm_lang_flag()`, `source_extensions()`, `elapsed_secs()` added to `core/builder/common.rs`.
* **Full Bare-Metal / Freestanding Automation** — introduced the `build.freestanding = true` configuration option. When enabled (or when a bare-metal target is detected), DCR automatically injects `-ffreestanding` during compilation and both `-nostdlib` and `-static` during linking.
* **Artifact Optimization (LTO & Strip)** — added `build.lto` (auto-injects `-flto` for compiler and linker) and `build.strip` (automatically strips debug symbols via linker `-s` flag) options to `dcr.toml`.
* **Compilation Thread Control** — added the `build.codegen-units` option to strictly limit the maximum number of parallel jobs utilized by the custom `parallel_build` worker pool.
* **Panic Behavior Management** — added `build.panic = "abort"` support. For C++ targets, it automatically strips exception handling and unwind tables via `-fno-exceptions`, `-fno-unwind-tables`, and `-fno-asynchronous-unwind-tables`.
### Changed
* **Intelligent Default Flags Generation** — automated injection of fallback optimization (`-O3`/`-O0`), debug (`-g`), and warning (`-Wall -Wextra`) flags is now suppressed for bare-metal and freestanding builds if `build.cflags` are overridden.
* **Centralized Bare-Metal Detection** — relocated the `is_bare_metal_target` helper to common build utilities (`src/utils/build.rs`) for unified access across the building core.
* **Architectural Refactoring**:
* Renamed `src/config.rs` to `src/templates.rs`.
* Started consolidation of configuration and build orchestration logic.
## 0.7.3 (2026-06-13)
### Added
* **`--vcs` option for `new` and `init` commands** — introduced explicit version control system selection via `--vcs \<git|none>`.
* **Git metadata integration in `--version`** — the CLI now appends the current short commit hash and a `-dirty` suffix if there are uncommitted changes in the DCR repository.
* **Automatic `.gitignore` generation** — Git repository initialization now automatically writes a `.gitignore` file excluding the `/target` directory.
* **Nested repository prevention** — automatic Git initialization is now skipped if `dcr new` or `dcr init` is executed inside an already existing Git repository.
* **VCS verification tests** — added `new_vcs_options_work` and `init_vcs_options_work` integration tests to ensure reliable repository behavior.
### Changed
* **Complete removal of `git2` dependency** — all Git actions (dependency fetching, VCS setup, status checks) are now delegated to the system `git` executable via `Command`. This simplifies compilation and drops the need for `vendored` and `openssl` features.
* **Migrated from `reqwest` to `ureq`** — replaced the heavy `reqwest` crate in `flag_update.rs` with the lightweight synchronous `ureq 2.10` client, reducing overhead and the final binary size.
## 0.7.2 (2026-06-07)
### Added
* `default_target_triple()` now respects `target_env` — Linux (gnu/musl) and Windows (msvc/gnu) use the correct environment instead of hardcoded values.
### Исправлено
* **macOS Apple Silicon builds failed with `_main` undefined** — `--target=` is now passed to ldflags, not just cflags. `default_target_triple()` uses `std::env::consts::ARCH` on macOS instead of hardcoded `x86_64`.
* **GitHub Stars and GPL-3.0 badges not rendering in README** — badge block converted to pure HTML.
### Changed
* Default target resolution extracted into shared `default_target_triple()` — removed duplication across build, run, clean.
## 0.7.1 (02.06.2026)
### Added
* **`--help` для всех команд** — `dcr build --help`, `dcr run --help`, `dcr new --help`,
`dcr init --help`, `dcr clean --help`, `dcr add --help`, `dcr fmt --help`,
`dcr setup --help`, `dcr tree --help`, `dcr gen --help`, `dcr --update --help`,
`dcr test --help`. Во всех результатах вывода используются стилизованные заголовки (зелёного цвета) и строки с информацией об использовании (голубого цвета).
* **Справочные страницы** — 12 страниц в формате troff в каталоге `man/man1/`: `dcr.1`, `dcr-build.1`,
`dcr-run.1`, `dcr-new.1`, `dcr-init.1`, `dcr-clean.1`, `dcr-add.1`, `dcr-test.1`,
`dcr-gen.1`, `dcr-fmt.1`, `dcr-tree.1`, `dcr-setup.1`.
* **Справочные страницы во всех пакетах** — install.sh, install_bsd.sh, PKGBUILD из AUR,
Debian (cargo-deb), RPM (cargo-generate-rpm), Nix (postInstall), Homebrew
(ресурс), Snap, ресурсы релизов GitHub.
* **Проверка имени проекта** — команды `dcr init` и `dcr new` теперь проверяют имена перед созданием файлов
. Допускаются только буквы ASCII, цифры, символы `_` и `-`.
* **Поля `documentation` и `homepage`** — добавлены в файл `Cargo.toml`.
* **Оптимизации профиля релиза** — `opt-level = "z"`, LTO, `codegen-units = 1`,
`panic = "abort"`, `strip = true` для уменьшения размера бинарных файлов.
* **Платформы Linux i686, armv7, riscv64** — добавлены в рабочий процесс выпуска и скрипты установки.
* **Платформы Linux musl i686 и armv7** — скомпилированы с помощью zigbuild в системе непрерывной интеграции (CI).
* **Пакеты AUR** — рабочий процесс публикации `dcr-dev`, `dcr-dev-bin`.
* **Публикация Snap** — автоматическая публикация Snapcraft в рамках непрерывной интеграции (CI).
* **Значок Snap** — в файле README.
### Changed
* **`validate_package_name` стал общедоступным** — его можно вызывать из команд CLI.
* **Таблица платформы README** — реорганизована: варианты libc вынесены в отдельные строки по ОС,
удалены лишние столбцы. Обновлен список архитектур Linux.
* **Вывод `gen.rs` без аргументов** — теперь используется стилизованный вывод вместо необработанного `eprintln!`.
* **`tree.rs`, `fmt.rs` и `setup.rs`** — теперь поддерживают аргументы для опции `--help`.
* **Команды установки из файла README** — `| bash` → `| sh` для обеспечения совместимости с POSIX.
### Fixed
* **`dcr new \<invalid-name>` создает каталог, а затем завершается с ошибкой** — теперь проверка
выполняется до начала любых операций с файлами.
* **`dcr init` при указании недопустимого имени каталога** — то же исправление.
* **Отсутствующие справочные страницы в установленных пакетах** — теперь поставляются во всех форматах.
* **Ложное срабатывание по букве диска Windows** — в модуле анализа файлов зависимостей.
* **CRLF (`\r\n`) вызывает сбой в работе парсера зависимостей** — теперь поддерживается обработка смешанных символов окончания строк.
* **Новая строка после обратного слеша не обработана** — при обработке экранирующих символов в функции `parse_d_file`.
## 0.7.0 (01.06.2026)
### Added
* **Поддержка целевых платформ OpenBSD и NetBSD** — полная маршрутизация по платформам с динамически генерируемыми тройками целевых параметров с использованием `std::env::consts::ARCH` и `std::env::consts::OS`. Затрагивает команды `build`, `run`, `clean` и модуль платформы.
* **`src/platform/bsd.rs`** — новый специальный модуль платформы BSD, общий для FreeBSD, OpenBSD и NetBSD, предоставляющий `bin_path`, `lib_path`, `elf_path`, `efi_path` и `shared_lib_path`.
* **`Параметр конфигурации build.out_dir`** — настраиваемый каталог вывода, который переопределяет путь по умолчанию `target/\<triple>/\<profile>` для конечных артефактов. Поддерживается в `build`, `run` и при проверке конфигурации.
* **Команда `dcr fmt`** — новая команда CLI, которая форматирует все исходные файлы C/C++ (`*.c`, `*.cpp`, `*.h`, `*.hpp`) в `src/` и `tests/` с помощью `clang-format`.
* **Инкрементальная компоновка** — функция `needs_link()` в `common.rs`, которая проверяет, не является ли какой-либо объектный файл более новым, чем скомпонованный результат, пропуская ненужную повторную компоновку. Реализовано для всех бэкэндов (`unix_cc`, `msvc`, `gas`, `nasm`).
* **`build.kind = «none»` и `«custom»`** — два новых типа проектов для специальных сценариев сборки, при которых не создается стандартный артефакт.
* **`install_bsd.sh`** — специальный скрипт установки, совместимый с POSIX, для систем BSD (FreeBSD, OpenBSD, NetBSD) с режимами загрузки бинарных файлов и сборки из исходного кода.
* **Поддержка Linux ARM64 в `install.sh`** — добавлено определение целевой тройки `Linux:aarch64|Linux:arm64` для загрузки готовых бинарных файлов.
* **Обнаружение ОС BSD в `install.sh`** — обнаружение FreeBSD, OpenBSD, NetBSD и определение целевой тройки.
* **`rust-toolchain.toml`** — явное привязывание инструментария к каналу `stable`.
* **Интеграционные тесты** — `build_with_target_config` (проверяет `build.target = «linux»`) и `build_with_out_dir` (проверяет настраиваемый каталог вывода).
* **`get_build_string_with_profile` стал `pub`** — чтобы `run.rs` мог определять конфигурацию настраиваемого каталога вывода.
### Changed
* **Изменена семантика `build.target`** — теперь строго содержит тройку целей (например, `x86_64-unknown-linux-gnu`) или короткое имя (`linux`, `macos`, `windows`). Больше не используется в качестве пользовательского каталога вывода — эта функциональность перенесена в `build.out_dir`.
* **`build.standard` стал опциональным** — изменен с `String` на `Option\<String>`. Проверка обеспечивает только непустоту для языков, отличных от ASM. Пропускается в выводе `dcr.toml`, если пуст.
* **`dcr run` с `out_dir`** — теперь определяет целевой каталог с учетом `build.out_dir`, если он настроен, через `get_build_string_with_profile()` из `build.rs`.
* **`collect_sources()` возвращает пустой вектор** вместо ошибки, если не найдено ни одного исходного файла, что позволяет проектам с `kind = «none»` или `kind = «custom»` не иметь исходных файлов.
* **Рефакторинг рабочего процесса выпуска CI/CD** — `git2` стал целевым (без vendored-openssl на Windows), кросс-компиляция на основе Zig для целей Linux, отличных от x86_64, очистка версий пакетов Arch Linux (тире → точки), символьная ссылка `gmake` для NetBSD.
* **Таблица совместимости README** — статус сборки/работы на FreeBSD, OpenBSD, NetBSD повышен с «сообщество/по возможности» до «официально поддерживается».
* **Обновлена документация** — `build-section.md` описывает новые поля `build.target` и `build.out_dir`. `target-directory.md` переписан для уточнения различия.
### Fixed
* **stdout/stderr `dcr run` не наследуются** — вывод дочернего процесса захватывался и выводился вручную, что приводило к сбоям интерактивных программ. Исправлено путем перехода на `Command::status()`.
* **Условие гонки в CI релиза** — задания матрицы сборки могли загружать ресурсы в релиз, который еще не существовал. Исправлено добавлением специального задания `create-release`.
* **Релиз GHA — переопределение стабильного набора инструментов** — устранены проблемы с переопределением набора инструментов Rust в CI.
* **Очистка версий пакетов Arch Linux** — строки версий с дефисами (например, `0.7.0-dev`) являются недопустимыми для `pkgver` в Arch Linux. Исправлено путем замены дефисов точками.
* **Права доступа GPG после Docker** — операции Docker изменяли владельца каталога GPG. Исправлено путем запуска `chown` после команд Docker.
* **Пути к артефактам пакетов RPM** — артефакты RPM размещались в `rpm/x86_64/` вместо `fedora/x86_64/`. Исправлено в рабочем процессе Dexoron Packages Index.
* **Надежность разбора JSON в `install.sh`** — добавлен `jq` в качестве основного парсера с резервным вариантом `python3` для поиска релизов в канале dev.
### Удалено:
* **Вспомогательная функция `format_roots()`** — удалена из `common.rs`. Использовалась только старым путем обработки ошибок в `collect_sources()`.
* **Отдельные шаги загрузки артефактов для каждой дистрибуции** — три отдельных шага `actions/download-artifact` заменены на унифицированный `gh release download --clobber`.

# Команды сборки
## `dcr build`
Собирает проект по `dcr.toml`.
```bash
dcr build # debug profile
dcr build --release # release build
dcr build --debug # explicit debug
dcr build --target aarch64-unknown-linux-gnu
dcr build --force # full rebuild (also re-runs build.steps / post_steps)
dcr build --clean # clean + build
dcr build --verbose # show compilation commands
dcr build --workspace pkg-a # build specific workspace package
```
Артефакты: `target/\<triple>/\<profile>/\<binary-name>` (Linux с явным целевым объектом).
With `[archive]` in `dcr.toml`, a FAT disk image is packed after a successful build.
## `dcr run`
Собирает (если исходники новее артефакта) и запускает бинарник.
```bash
dcr run
dcr run --release
dcr run --force # force rebuild then run
```
On a **workspace-only** root: if `[run].cmd` is set, that command is used after build; otherwise DCR delegates to a workspace member.
## `dcr clean`
Удаляет директорию `target/`(или `target/\<target>/\<profile>`).
```bash
dcr clean
dcr clean --release # очистить target/release/
dcr clean --target windows # очистить target/x86_64-pc-windows-msvc/
dcr clean --all # очистить все пакеты workspace

dcr add fmt pkg-config:fmt # system package via pkg-config
dcr add openssl pkg:openssl,libcrypto # multiple pkg-config packages
```
Префиксы источника:
* `path:` — локальный путь
* `git:` — URL адрес git-репозитория
* `github:` — расширение `https://github.com/\<user>/\<repo>`
* `gitlab:` — расширение `https://gitlab.com/\<user>/\<repo>`
* `pkg-config:` / `pkg:` — one or more packages resolved by `pkg-config`
* `http://` / `https://` / `git@` — полный URL
Флаги:
* `--branch \<name>` — git ветка
* `--tag \<name>` — git tag
* `--rev \<hash>` — git commit
Если источник не указан — DCR выполняет поиск в подключенных реестрах. A bare relative or absolute path is accepted as a path dependency.
For `pkg-config` dependencies, the referenced packages must already be installed
and provide `.pc` files. DCR invokes `pkg-config` during the build (using
`PATH` and `PKG_CONFIG_PATH`) and forwards the returned compiler and linker
flags; it does not download or build these packages.
## `dcr tree`
Показывает дерево зависимостей проекта.
```bash
dcr tree
```
Пример вывода:
```
my-app v0.1.0
├── fmt (registry)
│ └── spdlog (registry)
└── catch2 (registry)

# Команды проекта
## `dcr new \<name>`
Создает новый проект со стандартной структурой и `dcr.toml`. Аргумент `name` является обязательным.
В названии проекта допускаются только ASCII буквы, цифры и подчеркивания `_` и дефисы `-`.
```bash
dcr new my-app
dcr new my-app --vcs none
```
Flags:
* `--vcs \<git|none>` — Initialize version control system (defaults to `git` if available, or `none`).
Генерирует:
* `dcr.toml` с базовыми полями
* `src/main.c` с основным шаблоном
## `dcr init`
Инициализирует проект DCR в текущем (пустом) каталоге.
```bash
dcr init
dcr init --vcs none
```
Flags:
* `--vcs \<git|none>` — Initialize version control system (defaults to `git` if available, or `none`).
Название проекта взято из имени текущего каталога. Имя каталога должно соответствовать тем же правилам именования, что и в `dcr new`.

# Команды качества
## `dcr test`
Запускает тесты.
```bash
dcr test # debug профиль
dcr test --release # release профиль
dcr test --debug # явный debug
dcr test --help # подробная справка
```
Перед первым запуском нужно инициализировать тесты:
```bash
dcr test --init
```
Это создаёт `tests/dcr_test.h` (фреймворк) и `tests/test.c` (шаблон).
Что делает `dcr test`:
1. Собирает проект
2. Собирает файлы `tests/*.c` (только `.c`, не `.cpp`)
3. Компилирует и линкует каждый файл теста
4. Запускает каждый бинарник тестов
5. Вывод сводки: TOTAL, PASS, SKIP, FAIL
6. Возвращает ненулевой код при наличии FAIL
## `dcr fmt`
Форматирует исходный код C/C++ через `clang-format`.
```bash
dcr fmt
```
Процессы: `src/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}` и `tests/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}`.
Использует `.clang-format` в корне проекта (если таковой имеется), иначе стиль clang-format по умолчанию.
## `dcr lint`
Выполняет `clang-tidy` на C/C++ исходных файлах для статического анализа.
```bash
dcr lint # отобразить диагностику
dcr lint --fix # автоматически применить исправления
dcr lint --help # подробная справка
```
Процессы: `src/**/*.{c,cpp,cxx,cc}` и `tests/**/*.{c,cpp,cxx,cc}`.
Без параметра `--fix` clang-tidy выдает предупреждения и ошибки, не внося изменений в файлы.
При параметре `--fix` clang-tidy автоматически вносит предложения по исправлениям на месте.

# Часто задаваемые вопросы
## Реестр не найден
```
Ошибка: реестр не найден
```
**Решение:** Убедитесь, что файл `~/.dcr/config.toml` существует:
```toml
[registry.default]
url = "https://index.dcr.pm"
priority = 1
```
Если реестр кастомный, проверьте `DCR_INDEX_PATH`:
```bash
echo $DCR_INDEX_PATH
```
## Компилятор не найден
```
Ошибка: компилятор не найден
```
**Решение:** Убедитесь, что компилятор установлен и доступен в PATH.
```bash
какой gcc
какой clang
```
Или укажите явно через `[toolchain]` или `DCR_COMPILER`.
## Ctrl+C во время сборки
DCR корректно обрабатывает SIGINT: прерывает текущую компиляцию и завершает процесс с ненулевым кодом.
## Как создать библиотеку?
[Library Recipe](/docs/recipes/library-project).
## Как выполнить кросс-компиляцию для Windows?
См. [Cross-Compile Recipe](/docs/recipes/cross-to-windows).
## Как сделать мультипакетный проект?
См. [Workspace Recipe](/docs/recipes/multi-package-workspace).
## Bootloader / pure NASM OS image
Use `kind = "flat-bin"` (NASM `-f bin`) and optional `[archive]` for a FAT disk image.
See [OS-dev recipe](/docs/recipes/os-flat-bin-archive).
## How do I choose a download mirror?
`dcrup install` uses `--mirror auto` by default and tries **cf → gh → sf → ya**.
```bash
dcrup install stable --mirror cf
export DCRUP_MIRROR=ya
```
## Lock-файл устарел
При изменении зависимостей `dcr.lock` автоматически обновляется при следующем `dcr add`. Если нужно принудительно обновить — удалите `dcr.lock` и выполните `dcr build`.

## Создать проект
```bash
dcr new my-app
cd my-app
```
Будет создана структура:
```

compiler = "clang"
kind = "bin"
```
## Сборка
```bash
dcr build
```
Результат — `target/\<triple>/debug/my-app` (Linux) или `target/debug/my-app.exe` (Windows).
Профиль сборки:
```bash
dcr build --release # release сборка
dcr build --debug # debug (по умолчанию)
```
## Запустить
```bash
dcr run
```
Собирает (если нужно) и запускает бинарник.
## Первый тест
```bash
dcr test --init # создать шаблон теста
dcr test # запустить тесты
```
## Форматирование
```bash
dcr fmt # clang-format по .clang-format
```
## Linting
```bash
dcr lint # clang-tidy checks
dcr lint --fix # apply fixes automatically

# Установка
## dcrup (recommended)
Install and switch DCR versions (stable / dev / night, pin `0.8.2`, optional build from source).
### Linux / macOS / BSD / Windows (bash)
```sh
curl -fsSL https://sh.dcr-tool.ru | sh -s -- self-install
export PATH="$HOME/.dcr/bin:$PATH"
dcrup install stable
```
Non-interactive install of DCR in one shot:
```sh
curl -fsSL https://sh.dcr-tool.ru | sh -s -- install stable
export PATH="$HOME/.dcr/bin:$PATH"
```
### Windows (PowerShell)
```powershell
irm https://ps1.dcr-tool.ru | iex
# or download then run:
# irm https://ps1.dcr-tool.ru -OutFile dcrup.ps1
# powershell -File .\dcrup.ps1 self-install
# $env:Path += ";$env:USERPROFILE\.dcr\bin"
dcrup install stable
```
Optional cmd bootstrap (if you prefer `curl` of the cmd shim):
```bat
curl -fsSL -o dcrup.cmd https://cmd.dcr-tool.ru
```
After `self-install`, the command is **`dcrup`** (no `.sh` / `.ps1`): shims live in `~/.dcr/bin` (Unix) or `%USERPROFILE%\.dcr\bin` (Windows `dcrup.cmd`).
### Common dcrup commands
```sh
dcrup install stable # latest stable prebuilt (auto: cf → gh → sf → ya)
dcrup install 0.8.2 # pin → 0.8.2@stable
dcrup install 0.8.2@dev
dcrup install stable --libc musl # Linux: musl asset (default: gnu)
dcrup install stable --mirror cf # CloudFlare CDN
dcrup install stable --mirror ya # Yandex CDN (RU fallback)
dcrup install stable --build # cargo build --features archive
dcrup install night # always build from branch dev HEAD
dcrup default 0.8.2
dcrup update
dcrup list
dcrup show
dcrup which
```
Layout: `~/.dcr/toolchains/\<id>/dcr` and `~/.dcr/bin/dcr` → active version.
### Download mirrors
Prebuilt installs try **cf → gh → sf → ya** unless you pin a host.

# Проект библиотеки
Создание статической библиотеки и её использование в другом проекте.
## Шаг 1: Создать библиотеку
```bash
dcr new my-lib
```
`dcr.toml`:
```toml
[package]
name = "my-lib"
version = "0.1.0"
type = "lib"
[build]
language = "c"
standard = "c17"
kind = "staticlib"
```
`src/my_lib.h`:
```c
#ifndef MY_LIB_H
#define MY_LIB_H
int add(int a, int b);
#endif
```
`src/my_lib.c`:
```c
#include "my_lib.h"
int add(int a, int b) { return a + b; }
```
## Шаг 2: Собрать
```bash
cd my-lib
dcr build --release
```
Артефакты:
* `target/release/libmy-lib.a` (Linux/macOS)
* `target/release/my-lib.lib` (Windows)
* `target/include/` — заголовочные файлы
## Шаг 3: Использовать в проекте
```bash
dcr new my-app
cd my-app
dcr add ../my-lib
```
Автоматически:
* Добавляется include path на `target/include/` библиотеки
* Добавляется lib path на `target/release/`
* Линкуется `libmy-lib.a` / `my-lib.lib`

# Pure ASM / boot image (flat-bin + archive)
Minimal OS-dev style pipeline: assemble raw binaries with NASM, then pack a FAT floppy/image with an optional boot sector.
## Project layout
```
myos/
dcr.toml
src/
boot.asm # boot sector (512 bytes)
kernel.asm # payload
```
For multiple flat artifacts, use a **workspace** (one member per binary) or separate packages; a single `flat-bin` package produces one binary per source stem.
## Boot package (`flat-bin`)
```toml
[package]
name = "boot"
version = "0.1.0"
[build]
language = "asm"
compiler = "nasm"
kind = "flat-bin"
extension = "bin"
roots = ["src/boot.asm"]
```
```bash
dcr build
# → target/<…>/debug/boot.bin (NASM -f bin, no link)
```
## Disk image after build
```toml
[archive]
output = "target/{profile}/disk.img"
format = "fat12"
size = "1440K"
label = "MYOS"
bootsector = "target/{profile}/boot.bin"
[[archive.layout]]
from = "target/{profile}/kernel.bin"
to = "KERNEL.BIN"
```
* `format`: `fat12`, `fat16`, or `fat32`
* `size`: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default ~1.44 MiB)
* `bootsector`: written only when `offset` is omitted or `0`
* `from` may be a glob; `{profile}` is substituted in paths
## C kernel → flat binary
```toml
[build]
language = "c"
compiler = "clang"
kind = "flat-bin"
freestanding = true
filename = "kernel"
extension = "bin"
ldflags = ["-T", "linker.ld"]
```
Pipeline: objects → temporary linked ELF → `objcopy -O binary` → `kernel.bin`. Requires `objcopy` / `llvm-objcopy` in PATH.
## Other assemblers
| Tool | Notes |
| -------- | --------------------------------------------------------------------------------------- |
| **FASM** | Write `format binary` in the source; DCR writes `\<stem>.bin` directly |
| **GAS** | Assemble `.s` → obj → `objcopy -O binary` |
| **LLC** | `language = "llvm_ir"` → obj → objcopy |
| **MASM** | COFF obj → objcopy (needs binutils/LLVM objcopy) |
## Notes
* Single-file `roots` are supported: `roots = ["src/boot.asm"]`.
* `--force` re-runs `build.steps` / `build.post_steps` as well as recompilation.
* Prefer `kind = "elf"` if you need a relocatable ELF kernel without stripping to raw binary.

# Встроенные профили
Профили позволяют переопределять любые поля секции `[build]` для конкретного режима сборки.
## Конфигурация
```toml
[build]
language = "c"
standard = "c17"
cflags = ["-Wall"]
[build.debug]
cflags = ["-O0", "-g"]
[build.release]
cflags = ["-O3", "-flto"]
```
## Правила
Поля из `[build.\<profile>]` **мержатся поверх** `[build]`
* **Скалярные поля** (строки, числа, логические значения) — заменены
* Массивы (`cflags`, `ldflags`, ...) **заменяются полностью**, а не дополняются
Установите `inherit = false`, чтобы отключить наследование массивов (будут использоваться только собственные массивы профиля).
## Кастомные профили
Флаги по умолчанию для каждого профиля формируются из трёх полей конфигурации:
| Поле | Default cflags | Профили сборки |
| ---------------- | ------------------ | -------------- |
| `opt_level` | `-O0 -g` | `"3"` |
| `debug` | `true` | `false` |
| `предупреждения` | `["all", "extra"]` | `[]` |
Которые генерируют соответствующие флаги компилятора:
| Профиль | Действующие флаги |
| ------- | ---------------------------------------------------------- |
| `debug` | `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG` |
| `релиз` | `-O3 -DNDEBUG` |
Дополнительные параметры сборки можно включать или отключать для каждого профиля:
```toml
[build.release]
opt_level = "z"
lto = true
strip = true
panic = "abort"
codegen-units = "1"
[build.debug]
opt_level = "1"
debug = false
warnings = ["all", "error"]
```
## Target-specific профили
```toml
[build.linux]
cflags = ["-DLINUX"]
[build.windows.debug]
cflags = ["-DWIN32", "-O0", "-g"]
```
Порядок применения (в порядке убывания приоритета):
1. `[build.\<target>.\<profile>]`
2. `[build.\<profile>.\<target>]`
3. ]`или`[build.\<target>]\`
4. `[build.\<profile>]`.
5. `[build]`

# Система сборки
## Бэкенды компилятора
DCR поддерживает 4 бэкенда компиляции. Выбор происходит автоматически на основе расширения файла и target triple.
| Бэкенд | Файлы | Когда используется |
| --------- | --------------------------------------- | ------------------------------------- |
| `unix_cc` | `.c`, `.cpp`, `.cxx`, `.cc`, `.s`, `.S` | gcc/clang на Linux/macOS/BSD |
| `msvc` | `.c`, `.cpp`, `.cxx`, `.cc` | Windows (cl, clang-cl) |
| `газ` | `.s`, `.S` | ARM/ARM64 ассемблер |
| `nasm` | `.asm`, `.s` | x86/x86_64 ассемблер |
| `masm` | `.asm` | MASM (ml/ml64) в Windows |
| `fasm` | `.asm`, `.fasm` | Сборщик плоских деталей |
| `llvm_ir` | `.ll` | LLVM IR с помощью `llc -filetype=obj` |
## Поддержка Qt
DCR обеспечивает встроенную поддержку Qt для автоматической обработки метаобъектов (MOC, UIC, RCC).
Чтобы включить эту функцию, установите значение `build.qt = true` в файле `dcr.toml`. DCR автоматически обнаружит файлы, связанные с Qt (`.ui`, `.qrc`, `.h` с `Q_OBJECT`), и обработает их.
```toml
[build]
qt = true
```
*Примечание: Требуется установка модулей `qt6` (Core, Widgets, Gui, Svg) с помощью `pkg-config`.*
Если требуется специальная обработка, по-прежнему можно выполнить расширенную настройку с помощью файла `build.steps`:
```toml
[build.steps]
moc = "moc {in} -o {out}"
```
### Unix CC
* Компилятор определяется через `resolve_compiler()`: CC/CXX из [toolchain], DCR_COMPILER/env, PATH
* Поддерживает генерацию `.d` файлов для header dependency tracking
* Флаги: `-std=`, `-MMD -MF`, `-c -o`, `-I`, `-L`, `-l`
* Условные флаги, зависящие от настроек:
* `freestanding` или целевая среда «bare-metal»: `-ffreestanding` (компиляция), `-nostdlib -static` (линковка)
* `lto`: `-flto` (компиляция + линковка)
* `panic = "abort"`: `-fno-exceptions` (только для C++), `-fno-unwind-tables`, `-fno-asynchronous-unwind-tables`
### MSVC
* Поддерживает cl.exe и clang-cl.exe
* Флаги: `/std:`, `/Fo:`, `/Fe:`, `/I`, `/link`
### GAS / NASM
* GAS: `-I`, `-c -o`, `--defsym`
* NASM: `-I`, `-o`, `-D`, `-f` (format: win64/elf64/macho64/macho32/elf32; **`bin` when `kind = "flat-bin"`**)
* MASM: `/nologo /c /Fo\<obj> <source>`
* FASM: `<source> \<output>` (путь вывода — объектный файл)
* LLVM IR: `-filetype=obj <source> -o \<output>`
## Инкрементные сборки
Три уровня инкрементальности:
1. **mtime** — если выходной файл новее всех входных, файл не перекомпилируется
2. **`.d` files** — отслеживание изменений в заголовочных файлах (включая транзитивные)
3. **SHA256 fingerprint** — если флаги компиляции изменились, файл перекомпилируется (fingerprint хранится в `.dcr_fingerprint`)
## Параллельная компиляция
* Используется `thread::scope` для создания пула потоков
* Атомарная очередь задач (`AtomicU64`)
* Мьютекс на запись в stdout (`OUTPUT_MUTEX`)
* Количество потоков = `available_parallelism()`, ограниченное значением `build.codegen-units`, если оно задано
## Типы сборок
| Тип | Тип | Путь (пример для Linux) |
| ------------------ | ------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------- |
| `bin` | Исполняемый файл | `target/\<profile>/\<name>` (.exe) |
| `staticlib` | Статическая библиотека | `target/\<profile>/lib\<name>.a` (.lib) |
| `sharedlib` | Динамическая библиотека | `target/\<profile>/lib\<name>.so` (.dll/.dylib) |
| `efi` | UEFI приложение | `target/\<profile>/\<name>.efi` |
| `эльф` | ELF без стандартной библиотеки | `target/\<profile>/\<name>` |
| `нет` | Только компиляция, без линковки | — |
| `пользовательский` | Полный контроль filename + extension | `target/\<profile>/\<filename>.\<extension>` |
| `flat-bin` | Raw binary | ASM: `\<stem>.bin` (NASM `-f bin` / FASM / GAS·MASM·LLC via objcopy); C/C++: `\<name>.bin` (link + objcopy) |
## Disk images (`[archive]`)
After a successful build, if `[archive]` is present in `dcr.toml`, DCR formats a FAT volume and copies files from `layout` into the image. See [dcr.toml → archive](/docs/reference/dcr-toml#archive).
## Этапы сборки
DCR поддерживает pre-build и post-build шаги через Qt codegen:
* `build.steps` — команды, выполняемые перед компиляцией
* `build.post_steps` — команды, выполняемые после компиляции
Подстановки: `{stem}`, `{in}`, `{out}`.
`rcc` — Resource Compiler: `{stem}.qrc → qrc_{stem}.cpp`
```toml
[build.steps]
moc = "moc {in} -o {out}"
```
## pkg-config
Автоматический поиск (чтение из исходного файла конфигурации):
```toml
[build]
pkg_config = ["sdl2", "gl"]
```
DCR вызывает `pkg-config --cflags sdl2 gl` и `pkg-config --libs sdl2 gl` и добавляет результат в флаги компиляции/линковки.
## Подстановка переменных
Поддерживаемые переменные:
| Переменная | Описание |
| ----------------------- | ----------------------------------------- |
| `{version}` | Версия пакета |
| `{version_major}` | Часть, обозначающая основную версию |

# Кросс-компиляция
## Сокращённые названия
DCR поддерживает короткие имена платформ, которые автоматически раскрываются в полные triples:
| Краткое название | Полный тройной |
| ---------------- | -------------------------- |
| `linux` | `x86_64-unknown-linux-gnu` |
| `macos` | `x86_64-apple-darwin` |
| `windows` | `x86_64-pc-windows-msvc` |
```bash
dcr build --target windows
```
## Полные тройки
```bash
dcr build --target aarch64-unknown-linux-gnu
dcr build --target x86_64-pc-windows-gnu
dcr build --target armv7-unknown-linux-gnueabihf
```
## clang --target
При использовании clang DCR автоматически inject-ит `--target=\<triple>` в CFLAGS/CXXFLAGS.
```toml
[build]
compiler = "clang"
target = "aarch64-unknown-linux-gnu"
# Авто: cflags = ["--target=aarch64-unknown-linux-gnu"]
```
## Bare-Metal
Для целевых платформ, содержащих значения `none`, `-elf`, `eabi` или `baremetal`, DCR автоматически:
1. Для none/elf/eabi/bare-metal target-ов отключаются DCR default флаги (нет `-I` системных путей, нет `-l` libc).
2. **Вставляет `-ffreestanding`** на этапе компиляции и `-nostdlib -static` на этапе линковки
Кроме того, можно явно включить автономный режим:
```toml
[build]
freestanding = true
```
```bash
dcr build --target aarch64-none-elf
```
## Целевой каталог
By default, the compilation output directories are structured as follows:
* **Linux and BSD**: Always output to `target/\<triple>/\<profile>/` (using host triple if no target is specified).
* **macOS and Windows (without target)**: Output to `target/\<profile>/`.
* **macOS and Windows (with explicit target)**: Output to `target/\<triple>/\<profile>/`.

Параметры из исходного файла конфигурации (не в виде типизированной структуры):
* `pkg_config` — list of packages queried for build-wide compiler/linker flags
Dependencies can also declare a system package directly, for example
`fmt = { pkg-config = "fmt" }`. This records the package in `dcr.lock` and applies
the flags returned by `pkg-config --cflags` and `pkg-config --libs`.
* Путь к linker script
* `build.steps` / `build.post_steps` — этапы генерации кода
## Per-language overrides: `[build.c]`, `[build.cxx]`, `[build.asm]`, `[build.llvm_ir]`
Each language can have its own table that overrides the flat `[build]` settings:
```toml
[build]
compiler = "clang"
standard = "c11"
[build.c]
standard = "c23"
compiler = "gcc"
[build.cxx]
standard = "c++23"
compiler = "g++"
[build.asm]
compiler = "nasm"
flags = ["-felf64"]
[build.llvm_ir]
compiler = "llc"
```
The flat `[build]` acts as fallback; per-language tables take precedence for their language.
Пример:
```toml
[build]
language = ["cpp", "c"]
standard = "c17"
standard = "c23"
cxx_standard = "c++23"
compiler = "clang"
kind = "sharedlib"
cflags = ["-Wall", "-Wextra"]
pkg_config = ["sdl2", "gl"]
```
## [набор инструментов]
```toml
[toolchain]
cc = "/usr/bin/clang"
cxx = "/usr/bin/clang++"
as = "/usr/bin/as"
ar = "/usr/bin/ar"
ld = "/usr/bin/ld.lld"
uic = "/usr/bin/uic" # Qt
moc = "/usr/bin/moc" # Qt
rcc = "/usr/bin/rcc" # Qt
```
Raw config также поддерживает `uic`, `moc` и `rcc` для генерации кода Qt.
## [зависимости]
См. [dependencies](/docs/reference/dependencies).
## [запустить]
```toml
[запустить]
cmd = "./target/{profile}/{name}"
```
Подстановки:
* `{version}` — версия из [package]
* `pkg_config`
* `{profile}` — отладочная / релизная версия
* `{name}` — имя из [package]
По умолчанию `cmd` вычисляется как `./target/{profile}/{name}`.
## [рабочая область]
См. [workspaces](/docs/reference/workspaces).
## [archive]
Optional post-build step: format a FAT volume and copy built artifacts into a disk image. Runs after a successful package build (and after workspace member builds that define `[archive]`).
Requires DCR built with the `archive` Cargo feature (`cargo build --features archive`). Release binaries include this feature.
| Field | Required | Description |
| ------------ | -------- | ------------------------------------------------------------------------------------------- |
| `output` | yes | Image path relative to project root (`{profile}` allowed) |
| `format` | yes | `fat12`, `fat16`, or `fat32` |
| `size` | no | Image size: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default `1474560` ≈ 1.44 MiB) |
| `offset` | no | Byte offset of the FAT volume inside the image (default `0`) |
| `label` | no | Volume label (max 11 chars, default `VOLUME`) |
| `bootsector` | no | Path to a 512-byte boot sector written at offset 0 when `offset` is 0 (`{profile}` allowed) |
| `layout` | no | List of `{ from, to }` entries (files or globs → path inside the volume) |
```toml
[archive]
output = "target/{profile}/disk.img"
format = "fat12"
size = "1440K"
label = "MYOS"
bootsector = "target/{profile}/boot.bin"
[[archive.layout]]
from = "target/{profile}/kernel.bin"
to = "KERNEL.BIN"
[[archive.layout]]
from = "assets/*"
to = "/"
```
Typical pairing with `kind = "flat-bin"` (NASM `-f bin`) for bootloaders and pure-ASM OS images.
## `flat-bin` (kind)
Produces a raw binary (default extension `bin`) for boot sectors, kernels, and freestanding payloads.
### Assemblers
| Tool | Language / compiler | How flat-bin is produced |
| ---- | ------------------------------------------ | -------------------------------------------- |
| NASM | `language = "asm"`, `compiler = "nasm"` | `-f bin` → `\<stem>.bin` |
| FASM | `compiler = "fasm"` | direct write (use `format binary` in source) |
| GAS | `compiler = "as"` / `"gas"` | assemble → `objcopy -O binary` |
| MASM | `compiler = "ml"` / `"ml64"` | assemble → `objcopy -O binary` |
| LLC | `language = "llvm_ir"`, `compiler = "llc"` | `-filetype=obj` → `objcopy -O binary` |
```toml
[build]
language = "asm"
compiler = "nasm"
kind = "flat-bin"
extension = "bin"
roots = ["src/boot.asm"]
```
### C / C++
Compile all sources, link with `-nostdlib -static` (plus your `ldflags` / `ldscript`), then convert the intermediate ELF/PE with `objcopy -O binary` to `\<filename|name>.bin`.
```toml
[build]
language = "c"
compiler = "clang"
kind = "flat-bin"
freestanding = true
filename = "kernel"
extension = "bin"
ldscript = "linker.ld"
ldflags = ["-T", "linker.ld"]
```
Notes:
* Multi-file **ASM** packages emit one `\<stem>.bin` per source; **C/C++** emit a single project binary.
* `objcopy` tools tried in order: `llvm-objcopy`, `objcopy`, `gobjcopy`.
* Incompatible with `build.qt = true`.
* `dcr run` rejects `flat-bin` (not a host executable).

# Зависимости
## Форматы
The `[dependencies]` section supports registry, path, Git, and `pkg-config` dependencies:
### Строка (реестр)
```toml
[dependencies]
fmt = "10.1.1"
spdlog = "^1.12"
catch2 = ">=3.0,<4.0"
```
Строка версии используется без изменений для поиска в реестре.
### Табличный (git)
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0" }
```
Fields: `git`, `branch`, `tag`, `rev`, `mode`, `include`, `lib`, `libs`.
### Табличный (path)
```toml
[dependencies]
mylib = { path = "../mylib" }
```
For a prebuilt external library, specify its layout explicitly. The three
arrays are paths relative to the dependency root (`include`, `lib`) and linker
names (`libs`):
```toml
[dependencies]
dcr-math = { path = "../deps/dcr-math", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
### Table (`pkg-config`)
Use an installed `.pc` package when the library is provided by the operating system
or another system package manager. DCR invokes `pkg-config --cflags` and
`pkg-config --libs`, preserving include, library, linker, and other flags:
```toml
[dependencies]
fmt = { pkg-config = "fmt" }
openssl = { pkg-config = ["openssl", "libcrypto"] }
```
The `pkg-config` executable must be available in `PATH`. The named `.pc` files must
be available through pkg-config's standard search paths or via `PKG_CONFIG_PATH`.
These dependencies are not downloaded or built by DCR; they are recorded in
`dcr.lock` with a `pkg-config+...` source.
## Реестр
## RegistryDCR использует реестр пакетов для поиска зависимостей по имени.```toml
# ~/.dcr/config.toml
[registry]
main = { url = "https://github.com/dcr-ports/dcr-index", priority = 1 }
```
```toml
# ~/.dcr/config.toml
[registry.default]
url = "https://index.dcr.dexoron.tech"
priority = 1
```
Приоритет реестра: порядок в файле `config.toml`. Переменная `DCR_INDEX_PATH` переопределяет путь к index.json.
## Git-зависимости
Git dependencies are cloned into `~/.dcr/git/`; their exact checked-out commit is written to `dcr.lock`.
Both Git and path dependencies have two modes:
* **DCR package:** the source has `dcr.toml`. DCR builds it before the consumer and uses the package name from its manifest for linking.
* **Prebuilt library:** it provides existing headers and binaries through `include`, `lib`, and `libs`. DCR passes them to the compiler/linker without building the dependency.
The mode is normally detected automatically. Use `mode = "build"` or `mode = "prebuild"` when a source contains both a manifest and prebuilt artifacts and you need to choose explicitly.
`dcr-math-lib` publishes both forms. Select its prebuilt library explicitly:
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0", mode = "prebuild", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
DCR supports specifying branch/tag/rev for git sources:
* `branch` — переключиться на ветку
* `tag` — переключиться на тег
* `rev` — переключиться на конкретный коммит
* `features` — флаги функций (проанализированы, но не влияют на сборку)
## Path dependencies
Local paths may point at a DCR package or a prebuilt external library. A path DCR package is built before its consumer, including its own path/git dependencies. DCR detects dependency cycles. A prebuilt library is never built by DCR; it is linked from the directories declared in its dependency entry.
```toml
[dependencies]
mylib = { path = "/abs/path/to/lib" }
mylib = { path = "../relative/path" }
```
For DCR packages, the package name from `dcr.toml` is used for linking (so the dependency key may differ from the library name). Header resolution includes the packaged `target/include` directory and link search includes `target/lib`.
### Recommended library layouts
Buildable DCR library:
```text
dcr-math-lib/
├── dcr.toml
└── src/
├── dcr_math.c
└── dcr_math.h
```
Prebuilt library:
```text
dcr-math-lib/
├── include/
│ └── dcr_math.h
└── lib/
└── libdcr-math.a # or .so / .lib
```
`libs` contains linker names without the `lib` prefix and file extension: use
`["dcr-math"]` for `libdcr-math.a`.
If one repository contains both forms, keep the prebuilt files in `include/` and `lib/` and select the mode explicitly:
```toml
[dependencies]
dcr-math = { git = "https://github.com/dexoron/dcr-math-lib.git", tag = "v0.1.0", mode = "prebuild", include = ["include"], lib = ["lib"], libs = ["dcr-math"] }
```
For a local copy, replace `git` with `path = "../dcr-math-lib"`. In `prebuild` mode DCR does not run the dependency build, even when `dcr.toml` is present.
## dcr.lock
Dependency lock file. Contains package names and sources.
Created during `dcr build` for resolved registry, path, and Git dependencies. Not updated during `dcr add` — only on the next `dcr build`.
## Resolution process
1. Resolve dependency sources (registry → git → path)
2. Fetch git dependencies into `~/.dcr/git/` and check out the requested ref
3. Build DCR package dependencies recursively
4. Collect `include_dirs`, `lib_dirs`, `libs` for the compiler

# Поддержка платформ
## Тройные цели
DCR нормализует target triple через `platform_triple::normalize_triple()`. Если задано имя платформы (short name), оно раскрывается в triple.
### Linux
```
target/<arch>-unknown-linux-<env>/<profile>/
```
Architectures: `x86_64`, `aarch64`, `i686`, `armv7`, `riscv64` (host-detected).
Environments: `gnu` (default), `musl`.
Тип артефакта: ELF. Расширения: `.so` для sharedlib, `.a` для staticlib
### macOS
```
target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
```
Поддержка архитектур: `x86_64`, `aarch64`.
`.dylib` для sharedlib, `.a` для staticlib
### Windows
```
target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
```
Поддержка архитектур: `x86_64`, `aarch64`.
Environments: `msvc` (default), `gnu` (MinGW).
Расширения: `.exe` (бинарный файл), `.lib` (статическая библиотека), `.dll` (общая библиотека), `.efi` (UEFI).
### BSD
```
target/<arch>-unknown-<os>/<profile>/
```
Поддерживаемые системы: `freebsd`, `openbsd`, `netbsd`.
## Определение хоста
`platform_triple::host_triple()` возвращает тройку текущей системы. Используется как fallback, если `target` не указан.

# Рабочие пространства
Workspaces позволяют управлять несколькими пакетами в одном репозитории.
## Конфигурация
```toml
[workspace]
members = [
{ path = "pkg-a" },
{ path = "pkg-b", deps = ["pkg-a"] },
{ path = "pkg-c", deps = ["pkg-a", "pkg-b"], main = true },
]
```
### Поля member
| Поле | Описание |
| ------ | -------------------------------------------- |
| `path` | Путь к пакету (относительно корня workspace) |
| `deps` | Зависимости от других member-ов |
| `main` | Пометить как главный пакет |
## Топологическая сортировка
DCR автоматически сортирует пакеты по зависимостям: пакет A собирается раньше B, если B зависит от A.
Циклические зависимости обнаруживаются и приводят к ошибке.
## Сборка
```bash
dcr build # собрать все пакеты
dcr build --workspace pkg-a # собрать только pkg-a
```
When building a workspace, DCR automatically injects include and library paths of dependent workspace members:
* **Include Paths**: Automatically resolves and injects header directories of dependencies, including the member's `src/` directory, local `include/` directory, and the packaged `target/include` directory.
* **Library Paths**: Injects compiled library search paths (`target/lib` as well as target-specific build folders) to allow automatic linking with member libraries.
## Очистка
```bash
dcr clean # очистить только корневой target/
dcr clean --all # очистить target/ всех пакетов
```
## Наследование
Если у member-а нет своей секции `[build]`, а в корневом `[build]` указано `inherit = true`:
```toml
[build]
inherit = true
language = "c"
standard = "c17"
```
## Workspace-only root (no build of its own)
A workspace root can set `workspace_only = true` — it won't be built itself, and doesn't need `language` or `compiler`:
```toml
[package]
name = "my-workspace"
version = "0.1.0"
[build]
workspace_only = true
kind = "bin"
[workspace]
lib-core = { path = "lib-core" }
app = { path = "app", deps = ["lib-core"] }

# Автоматическое обновление
## dcr --update
Автоматическое обновление до последней версии. Загружает бинарный файл (не архив) из раздела «Релизы» на GitHub и заменяет им текущий исполняемый файл.
```bash
dcr --update
```
## Как это работает
1. DCR определяет текущую платформу и архитектуру
2. Загружает последнюю версию с `api.github.com/repos/dexoron/dcr/releases/latest`
3. Сравнивает версии
4. Загружает соответствующий ресурс (прямой URL-адрес двоичного файла, а не архива)
5. Заменяет текущий исполняемый файл
## Названия активов
Шаблон: `dcr-\<triple>.\<ext> `
| Платформа | Название актива |
| -------------- | ------------------------------------- |
| Linux x86_64 | `dcr-x86_64-unknown-linux-gnu.tar.gz` |
| macOS x86_64 | `dcr-x86_64-apple-darwin.tar.gz` |
| macOS ARM64 | `dcr-aarch64-apple-darwin.tar.gz` |
| Windows x86_64 | `dcr-x86_64-pc-windows-msvc.zip` |
## AUR
Если DCR установлен через AUR, `--update` выводит предупреждение:
```
Обновление через менеджер пакетов: yay/paru -Syu {package_name} или sudo pacman -Syu {package_name}
```
## Ошибки
* Не удалось определить платформу — ошибка
* Не удалось скачать релиз — ошибка с URL
* Нет прав на запись бинарника — ошибка (нужен `sudo` или ручная установка)

* Все C/C++ файлы из `tests/`
* Include path: `tests/` (для `dcr_test.h`)
* Линкуется с основным проектом (если `type = "lib"`)

# Тестовая инфраструктура
DCR имеет встроенный минималистичный фреймворк для тестирования на C/C++.
## Макросы
### `EXPECT(expr, ...)`
Проверяет, что выражение истинно.
```c
EXPECT(1 + 1 == 2);
EXPECT(ptr != NULL, "ptr should not be NULL");
```
### `SKIP(...)`
Пропускает тест с опциональным сообщением.
```c
SKIP("not implemented on Windows yet");
```
### `TEST(имя)`
Определяет тест.
```c
TEST(сложение) {
EXPECT(1 + 1 == 2);
EXPECT(2 + 2 == 4);
}
```
### `TEST_CASE(name, ...)`
Регистрирует тестовый случай.
```c
TEST_CASE(math, a, b) {
EXPECT(a + b == b + a);
}
```
## Инициализация
```bash
dcr test --init
```
Создаются файлы:
* `tests/dcr_test.h` — заголовочный файл фреймворка
* `tests/test.c` — шаблон с примером теста
## Структура tests/
```
tests/
├── dcr_test.h # фреймворк (не редактировать)
├── test.c # основные тесты
└── ... # дополнительные .c файлы с тестами
```
Компилируются только файлы с расширением `.c` (файлы с расширением `.cpp` не поддерживаются).
