 # Changelog
 
+## [0.7.0] - 2026-06-02
+
+Added:
+
+- **OpenBSD and NetBSD target support** — full platform routing with dynamically generated target triples using `std::env::consts::ARCH` and `std::env::consts::OS`. Affects `build`, `run`, `clean`, and the platform module.
+- **`src/platform/bsd.rs`** — new dedicated BSD platform module shared by FreeBSD, OpenBSD, NetBSD, providing `bin_path`, `lib_path`, `elf_path`, `efi_path`, and `shared_lib_path`.
+- **`build.out_dir` configuration 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()` function in `common.rs` that checks whether any object file is newer than the linked output, skipping unnecessary re-linking. Implemented for all backends (`unix_cc`, `msvc`, `gas`, `nasm`).
+- **`build.kind = "none"` and `"custom"`** — two new project kind types for special build scenarios where no standard artifact is produced.
+- **`install_bsd.sh`** — dedicated POSIX-compliant install 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 triple detection for pre-built binary downloads.
+- **BSD OS detection in `install.sh`** — FreeBSD, OpenBSD, NetBSD detection and target triple resolution.
+- **`rust-toolchain.toml`** — explicit `stable` channel toolchain pinning.
+- **Nix support** — `flake.nix` for Nix package manager. Run via `nix run github:dexoron/dcr` or install with `nix profile install github:dexoron/dcr`. Contributed by community contributor.
+- **Snapcraft publish** — `dcrup` published on Snapcraft. Install with `sudo snap install dcrup`.
+- **Integration tests** — `build_with_target_config` (verifies `build.target = "linux"`) and `build_with_out_dir` (verifies custom output directory).
+- **`get_build_string_with_profile` made `pub`** — so `run.rs` can resolve custom output directory configuration.
+
+Changed:
+
+- **`build.target` semantics changed** — now strictly holds the target triple (e.g. `x86_64-unknown-linux-gnu`) or a short name (`linux`, `macos`, `windows`). No longer doubles as a custom output directory — that 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 when empty.
+- **`dcr run` with `out_dir`** — now resolves target directory respecting `build.out_dir` when configured, via `get_build_string_with_profile()` from `build.rs`.
+- **`collect_sources()` returns empty vec** instead of error when no source files are found, allowing `kind = "none"` or `kind = "custom"` projects to have 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 sanitization (dashes → dots), NetBSD `gmake` symlink.
+- **README compatibility table** — FreeBSD, OpenBSD, NetBSD build/runtime status upgraded from community/best-effort to officially supported.
+- **Documentation rewritten** — available at [dcr.dexoron.su/docs](https://dcr.dexoron.su/docs) or in the `docs/` directory. Installation guides, commands, and reference updated to reflect current CLI and config format.
+- **Site rewritten** — `dcr-site` migrated to Docusaurus with internationalization (i18n) support, improved navigation, and updated content across all sections.
+- **Dev channel dependency check in `install.sh`** — checks for `python3` or `jq` before attempting dev channel installations.
+
+Fixed:
+
+- **`dcr run` stdout/stderr not inherited** — child process output was captured and manually printed, breaking interactive programs. Fixed by switching to `Command::status()`.
+- **Release CI race condition** — build matrix jobs could upload assets to a release that did not yet exist. Fixed by adding a dedicated `create-release` job.
+- **GHA release — stable toolchain override** — resolved Rust toolchain override issues in CI.
+- **Arch Linux package version sanitization** — version strings with dashes (e.g. `0.7.0-dev`) are invalid for Arch Linux `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 package artifact paths** — RPM artifacts placed under `rpm/x86_64/` instead of `fedora/x86_64/`. Corrected in Dexoron Packages Index workflow.
+- **`install.sh` JSON parsing robustness** — added `jq` as primary parser with `python3` fallback for dev channel release lookups.
+
+Removed:
+
+- **`format_roots()` helper** — removed from `common.rs`. Was only used by the old error path in `collect_sources()`.
+- **Individual per-distro artifact download steps** — three separate `actions/download-artifact` steps replaced with unified `gh release download --clobber`.
+

-# Introduction
-
-DCR (Dexoron Cargo Realization) is a Cargo-style CLI for C/C++ projects.
-
-Current DCR focuses on a simple, predictable workflow:
-
-- create or initialize a project (`dcr new`, `dcr init`)
-- build with `debug` or `release` profiles (`dcr build`)
-- run binaries (`dcr run`)
-- clean artifacts (`dcr clean`)
-- update the installed binary (`dcr --update`)
-
-## What is implemented in this version
-
-- Project configuration in `dcr.toml` with `[package]`, `[build]`, `[dependencies]`.
-- Recursive source discovery in `src/`:
-  - C: `*.c`
-  - C++: `*.cpp`, `*.cxx`, `*.cc`
-- Compiler selection from `dcr.toml` (`clang`, `gcc`, `cl`, `clang-cl`, etc.).
-- ASM support via `language = "asm"` (GCC/Clang, NASM, GAS).
-- Mixed language builds via `language = ["c", "asm"]` and similar combinations.
-- Three build kinds:
-  - `bin` (default)
-  - `staticlib`
-  - `sharedlib`
-- Optional custom output directory via `build.target`.
-- Optional `build.platform` to pass architecture hints (`-march` / `/arch`).
-- Optional `build.exclude`/`build.include` for source/header selection.
-- Optional `build.roots`/`build.src_disable` to replace the default `src/` root.
-- Optional build steps with `build.steps` and `build.post_steps`.
-- Optional `build.pkg_config` integration.
-- Optional `build.clean` and `build.expect`.
-- Optional `[run].cmd` to override run command.
-- Workspace builds via `[workspace]` with per-project `dcr.toml`.
-- Path dependencies with include/lib resolution and `dcr.lock` generation.
-
-## Important behavior notes
-
-- `dcr.toml` is required for `build`, `run`, and `clean`.
-- `run` works only with `build.kind = "bin"`.
-- Incremental rebuild tracks source file timestamps and header dependencies (rebuilds when either source or included headers change).
-- Object files are always created under `target/<profile>/obj/`.

+# Changelog
+
+## 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`.

-# dcr add
-
-Add a dependency to `dcr.toml`.
-
-## Usage
-
-```bash
-dcr add <name> [source] [options]
-```
-
-If `<source>` is omitted and a registry is configured, DCR will look up the
-package by name in the registry and add it as a version dependency.
-
-## Sources
-
-- *omitted*: Look up in the configured registry.
-- `path:./path/to/lib`: Local directory.
-- `github:user/repo`: GitHub repository.
-- `gitlab:user/repo`: GitLab repository.
-- `git:host.com/user/repo`: Generic Git repository (HTTPS).
-- `https://...`: Full Git URL.
-
-## Options
-
-- `--branch <name>`: Use a specific branch.
-- `--tag <name>`: Use a specific tag.
-- `--rev <sha>`: Use a specific commit hash.
-
-## Examples
-
-```bash
-dcr add my_lib path:./libs/my_lib
-dcr add cool_lib github:user/cool_lib
-dcr add shared_lib gitlab:org/shared --branch develop
-dcr add custom_lib git:git.internal.com/r/lib --tag v1.0.0
-dcr add mylib                    # Looks up in registry

-# dcr build
-
-Builds the project in `debug` or `release` profile.
-
-## Usage
-
-```sh
-dcr build
-dcr build --debug
-dcr build --release
-dcr build --target linux --release
-dcr build --release --force
-dcr build --debug --clean
-```
-
-## What `build` does
-
-1. Checks that `dcr.toml` exists and is valid.
-2. Reads build settings from `[build]`.
-3. Resolves path dependencies from `[dependencies]`.
-4. Creates required output directories.
-5. Recursively compiles sources from `src/`.
-6. Links final artifact (binary or library).
-
-## Config values used
-
-- `package.name`
-- `build.filename`
-- `build.extension`
-- `build.compiler`
-- `build.language`
-- `build.standard`
-- `build.kind`
-- `build.target`
-- `build.platform`
-- `build.cflags`
-- `build.ldflags`
-- `build.ldscript`
-- `build.debug` / `build.release`
-- `build.exclude`
-- `build.include`
-- `build.pkg_config`
-- `build.steps`
-- `build.post_steps`
-- `build.generated`
-- `build.expect`
-- `build.clean`
-
-## Source selection
-
-- `language = "c"` -> `*.c`
-- `language = "c++" | "cpp" | "cxx"` -> `*.cpp`, `*.cxx`, `*.cc`
-- `language = "asm"` -> `*.s`, `*.S`, `*.asm`
-- Mixed languages are supported with arrays, for example `language = ["c", "asm"]`.
-- By default sources are searched in `src/`; use `build.roots` and `build.src_disable` to override.
-
-## Notes
-
-- Profile flag (`--debug` / `--release`) can appear in any argument position (duplicates are rejected).
-- Unknown profile flags return an error.
-- `--target <triple>` builds for specified target (short names: `linux`, `macos`, `windows`).
-- `--verbose` prints the compiler/linker command lines to stderr (also works via `DCR_DEBUG` env var).
-- If no `--target`, builds for `build.targets` or native.
-- Incremental rebuild checks source/object mtime and tracked header dependencies.
-- `--force` skips build cache checks and recompiles.
-- `--clean` removes `target/<profile>` and `build.clean` paths before building.
-- `build.filename` + `build.extension` allow full control over the final artifact name (e.g. `KERNEL.BIN` instead of using `package.name`). When `build.kind = "efi"`, the output is a PE32+ executable with `.efi` extension.
-- `build.kind = "efi"` links with `-shared -nostdlib -Wl,-dll -Wl,--subsystem,10` for UEFI PE32+ format. Use `build.filename` and `build.extension` for full control over the artifact name.
-- `build.kind = "elf"` produces a bare-metal ELF executable. Linking flags are user-controlled via `build.ldflags` (no PIE/CRT defaults are added).
-- Default GCC/Clang profile flags: `debug` -> `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG`, `release` -> `-O3 -DNDEBUG`.
-  These defaults are **not applied** for bare-metal targets (e.g. `aarch64-none-elf`, targets containing `none` / `-elf` / `eabi`).
-- For `language = "asm"` with `compiler = "as"`/`"gas"`, use `.s` files (no preprocessing). For `.S`, use `gcc` or `clang`.
-- In workspace root, `dcr build` builds all members in dependency order.
-- `build.exclude` removes paths from source/header collection; `build.include` re-allows matching paths and has priority over `exclude`.
-- `build.steps` run before compilation; `build.post_steps` run after linking.
-- `build.generated` is cleaned when `build.steps` need to rerun; `build.expect` is verified after post-steps.

-# dcr clean
-
-Removes build artifacts in `target/`.
-
-## Usage
-
-```sh
-dcr clean
-dcr clean --debug
-dcr clean --release
-dcr clean --all
-dcr clean --release --all
-```
-
-## Behavior
-
-- Without arguments: removes entire `target/`.
-- With profile: removes only the profile-specific directory. Respects `build.target` from config: if `build.target = "aarch64-unknown-linux-gnu"`, cleans `target/aarch64-unknown-linux-gnu/<profile>/`.
-- With `--all`: also cleans all workspace members.
-- Additionally removes paths from `build.clean` if configured.
-- `build.clean` supports `{profile}` and version placeholders.
-
-## Validation
-
-- `dcr.toml` must exist.
-- Unknown flags are treated as error.
-- If `target` or selected profile directory does not exist, command prints a warning.

-# dcr gen
-
-Generates IDE and build tool integration files for C/C++ development environments.
-
-## Usage
-
-```sh
-dcr gen project-info
-dcr gen project-info --release
-dcr gen compile-commands
-dcr gen compile-commands --debug
-dcr gen vscode
-dcr gen vscode --release
-dcr gen clion
-dcr gen clion --debug
-```
-
-## Subcommands
-
-### `dcr gen project-info`
-
-Outputs project metadata as JSON array.
-
-```sh
-dcr gen project-info [--debug | --release]
-```
-
-Outputs structured information about the project (root project + all workspace members if present):
-
-```json
-[
-  {
-    "name": "my-project",
-    "version": "1.0.0",
-    "root": "/path/to/root",
-    "profile": "debug",
-    "language": "c++",
-    "standard": "c++17",
-    "compiler": "g++",
-    "kind": "bin",
-    "sources": ["/path/to/root/src/main.cpp", ...],
-    "include_dirs": ["/path/to/dep/include", ...],
-    "lib_dirs": ["/path/to/dep/lib", ...],
-    "libs": ["somelib", ...],
-    "cflags": ["-Wall", ...],
-    "ldflags": ["-lm", ...]
-  }
-]
-```
-
-This is useful for integrating DCR projects with custom build tools or scripts.
-
-### `dcr gen compile-commands`
-
-Generates `compile_commands.json` for use by `clangd`, `clang-tidy`, and other tools.
-
-```sh
-dcr gen compile-commands [--debug | --release]
-```
-
-Writes `./compile_commands.json` containing compilation database entries for all source files. This file is recognized by:
-- LSP servers (`clangd`, `clang-tools-extra`)
-- Linters (`clang-tidy`)
-- Format tools (`clang-format`)
-
-The entries include:
-- Full compiler command with flags
-- Source file path
-- Object file output path
-- Project root as working directory
-
-### `dcr gen vscode`
-
-Generates Visual Studio Code integration files.
-
-```sh
-dcr gen vscode [--debug | --release]
-```
-
-Creates `.vscode/` directory with:
-
-- **`launch.json`**: Debug configurations (one per binary target, debug + release variants)
-- **`tasks.json`**: Build/run/clean tasks using `dcr` commands
-- **`settings.json`**: Clangd configuration pointing to `compile_commands.json`
-- **`extensions.json`**: Recommends `clangd`, disables `cpptools`
-- **`compile_commands.json`**: Compilation database (same as `dcr gen compile-commands`)
-
-Usage in VSCode:
-- Open the Command Palette (`Ctrl+Shift+P`) and select **"Debug: Start Debugging"** to run debugger
-- Press `Ctrl+Shift+B` to run the build task
-- Clangd will provide IntelliSense and diagnostics based on `compile_commands.json`
-- Generated `launch.json` uses CodeLLDB (`type: "lldb"`), so install `vadimcn.vscode-lldb`
-
-### `dcr gen clion`
-
-Generates JetBrains CLion integration files.
-
-```sh
-dcr gen clion [--debug | --release]
-```
-
-Creates `.idea/` directory with:
-
-- **`externalTools.xml`**: Registers DCR build/clean/gen commands as external tools
-- **`customTargets.xml`**: Defines build targets for debug and release
-- **`misc.xml`**: Points CLion to `compile_commands.json` for compilation database
-- **`.idea/.gitignore`**: Ignores auto-generated files
-- **`runConfigurations/*.xml`**: Debug run configs (one per binary target)
-- **`compile_commands.json`**: Compilation database (same as `dcr gen compile-commands`)
-
-Usage in CLion:
-- Build/clean via **Tools → DCR → Build Debug/Release/Clean**
-- Run/debug via **Run → Run Configurations** (dropdown) → select generated config
-- Code completion and diagnostics come from the compilation database
-
-## Config values used
-
-- `package.name`
-- `build.compiler`
-- `build.language`
-- `build.standard`
-- `build.kind`
-- `build.target`
-- `build.platform`
-- `build.cflags`
-- `build.ldflags`
-- `build.debug` / `build.release`
-- `build.exclude`
-- `build.include`
-- `build.pkg_config`
-- `build.roots`
-- `build.src_disable`
-- Workspace members (if `[workspace]` is present)
-
-## Workspace support
-
-When running `dcr gen` in a workspace root, all commands process both the root project and all workspace members:
-
-- `project-info` returns an array with entries for each member + root
-- `compile-commands` includes entries from all members
-- `vscode` and `clion` generate unified configurations that work across all members
-
-## Troubleshooting
-
-### Clangd not picking up includes
-
-- Ensure `compile_commands.json` exists in the workspace root
-- In VSCode settings, verify `clangd.arguments` includes `--compile-commands-dir=<workspace-root>`
-- Rebuild via `dcr gen compile-commands` if sources or dependencies changed
-
-### Debug configuration not working
-
-- Verify binary paths in `launch.json` match actual build output (`target/<profile>/binary-name`)
-- For workspace projects, each member's debug config uses its own `target/` directory
-- Ensure GDB/LLDB is installed: `gdb --version` or `lldb --version`
-- If VSCode reports unsupported debugger type, install the extension that matches `launch.json` type (`vadimcn.vscode-lldb` for `lldb`)
-
-### CLion not recognizing includes
-
-- Regenerate via `dcr gen clion --debug`
-- File → Invalidate Caches → Invalidate and Restart
-- Verify `.idea/misc.xml` points to correct `compile_commands.json` path
-
-## Notes
-
-- Profiles default to `debug` if not specified
-- Generation does not require the project to be built first
-- Generated files are safe to commit; they are generated from `dcr.toml` and thus repeatable
-- IDE configurations may be customized after generation, but changes will be overwritten on next `dcr gen` run
-- For multi-binary projects, `vscode` and `clion` generate debug configs for all binaries (both debug + release variants)

-# dcr run
-
-Builds the project and runs the resulting binary.
-
-## Usage
-
-```sh
-dcr run
-dcr run --debug
-dcr run --release
-dcr run --target linux --release
-dcr run --release --force
-dcr run --debug --clean

-3. Runs the same build flow as `dcr build`.
-4. Executes the built artifact path for the selected profile.
-5. If `[run].cmd` is set, runs that command instead of the built binary.
-
-## Restrictions
-
-- If `build.kind` (or `build.{profile}.kind`) is `"staticlib"` or `"sharedlib"`, `run` exits with error.
-- The profile is selected from the first argument.
-- `--target <triple>` runs the binary for specified target (short names: `linux`, `macos`, `windows`).
-- `--force` skips build cache checks and recompiles.
-- `--clean` removes `target/<profile>` and `build.clean` paths before building.
-
-## `run.cmd` variables
-
-`run.cmd` supports the same variables as build steps: `{profile}`, `{version}`, `{version_major}`,
-`{version_minor}`, `{version_patch}`, `{version_suffix}`, `{version_suffix_dash}`.
-The command runs via `sh -c` on Unix and `cmd /C` on Windows.
-
-## On build failure
-
-`dcr run` attempts to launch an existing binary from the same profile if present; otherwise it reports that code errors must be fixed.

-# dcr test
-
-Runs the project's test suite.
-
-## Usage
-
-```sh
-dcr test
-dcr test --debug
-dcr test --release
-dcr test --target linux
-dcr test --init
-```
-
-## What `test` does
-
-1. Builds the project with the specified profile/target.
-2. Compiles test files in `tests/` (e.g., `tests/test.c`) into a test binary.
-3. Runs the test binary and parses output for PASS/SKIP/FAIL results.
-4. Reports summary with colored output.
-
-## Test Structure
-
-DCR uses a simple test framework:
-
-- Header: `tests/dcr_test.h` (generated by `dcr test --init`)
-- Test file: `tests/test.c` (template generated by `dcr test --init`)
-- Macros: `TEST(name)`, `TEST_CASE(name)`, `EXPECT(condition)`, `SKIP(reason)`
-- Output: `[PASS] test_name`, `[FAIL] test_name`, or `[SKIP] test_name`
-
-## Config values used
-
-- `package.name`
-- `build.compiler`, `build.language`, `build.standard`
-- `build.cflags`, `build.ldflags`
-- `build.debug` / `build.release`
-- `build.targets` (if specified)
-
-## Notes
-
-- Test binary is linked with the main project (for lib projects) or standalone.
-- `--init` creates `tests/dcr_test.h` and `tests/test.c` if missing.
-- Tests run in debug mode by default. Use `--release` for release mode.
-- Custom test logic can be added by editing `tests/test.c`.
-- Fails if no `tests/test.c` exists (run `dcr test --init` first).

+## `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.

-# Build profiles
-
-DCR supports two profiles:
-
-- `debug` (default)
-- `release`
-
-## How to select
-
-```sh
-dcr build --debug
-dcr build --release
-dcr run --release
-dcr clean --debug
-```
-
-You can also add `--force` or `--clean` to `build`/`run`.
-
-## Default profile flags
-
-### GCC/Clang-like toolchains
-
-- `debug`: `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG`
-- `release`: `-O3 -DNDEBUG`
-
-### MSVC toolchain
-
-- `debug`: `/Od /Zi /W4 /DDCR_DEBUG /Oy-`
-- `release`: `/O2 /DNDEBUG`
-
-## Artifacts
-
-By default:
-
-- `target/debug/<name>` (or `.exe` on Windows)
-- `target/release/<name>` (or `.exe` on Windows)
-
-Default compiler flags:
-
-GCC/Clang:
-
-- `debug`: `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG`
-- `release`: `-O3 -DNDEBUG`
-
-MSVC:
-
-- `debug`: `/Od /Zi /W4 /DDCR_DEBUG /Oy-`
-- `release`: `/O2 /DNDEBUG`
-
-Static library mode (`kind = "staticlib"`):
-
-- Linux/macOS: `lib<name>.a`
-- Windows: `<name>.lib`
-
-Shared library mode (`kind = "sharedlib"`):
-
-- Linux: `lib<name>.so`
-- macOS: `lib<name>.dylib`
-- Windows: `<name>.dll`
-
-## Profile overrides
-
-Use `[build.debug]` and `[build.release]` to override build settings per profile.
-All values inherit from `[build]`. If a field is present in the profile table, it replaces the base value.
-For arrays (like `cflags`/`ldflags`), the profile value is appended to the base array.
-
-```toml
-[build.debug]
-cflags = ["-g3"]
-
-[build.release]
-cflags = ["-O3"]
-ldflags = ["-s"]
-```

-
-## Fields
-
-- `language` (string or array, required): `c`, `c++`, `cpp`, `cxx`, or `asm`.
-  Mixed languages can be specified as an array, for example `["c", "c++", "asm"]`.
-- `standard` (string, required): C language standard passed to compiler (e.g. `c11`, `c17`, `gnu11`).
-- `cxx_standard` (string, optional): C++ language standard passed to compiler for `.cpp`/`.cxx`/`.cc` files
-  (e.g. `c++17`, `gnu++17`, `c++20`). When set, overrides `standard` for C++ sources.
-- `compiler` (string, required): compiler command (for example `clang`, `gcc`, `cl`).
-- `kind` (string, required): `bin`, `staticlib`, `sharedlib`, `efi`, or `elf`.
-- `filename` (string, optional): custom output filename (without extension). Overrides `package.name` for the final artifact.
-- `extension` (string, optional): custom file extension without the leading dot (e.g. `BIN`, `efi`, `EFI`). Combined with `filename`.
-- `inherit` (bool, optional): inherit settings from base `[build]` (default `true`). If `false`, only use target/profile specific settings.
-- `targets` (string array, optional): list of targets to build simultaneously. Supports short names (`linux`, `macos`, `windows`).
-- `target` (string, optional): custom output directory for final artifact.
-  When set, DCR automatically injects `--target=<value>` into `cflags` (useful for clang cross-compilation).
-- `platform` (string, optional): architecture hint for compiler (used for `-march` or `/arch`).
-- `cflags` (string array, optional): extra compile flags.
-  Supports variable substitution — see [Variable substitution](#variable-substitution) below.
-- `ldflags` (string array, optional): extra link flags.
-  Supports variable substitution — see [Variable substitution](#variable-substitution) below.
-- `ldscript` (string, optional): linker script path. Passed as `-T <path>` to the linker. Useful for bare-metal/embedded/freestanding targets.
-- `exclude` (string array, optional): paths or glob patterns to skip during source/header collection.
-- `include` (string array, optional): allowlist paths or globs that override `exclude`.
-- `include` directory entries (non-glob) are also passed to the compiler as `-I` include paths.
-- `roots` (string array, optional): additional source roots to scan instead of `src/`.
-- `src_disable` (bool, optional): disables default `src/` root when true.
-- `pkg_config` (string array, optional): packages used to append `pkg-config --cflags/--libs`.
-- `generated` (string array, optional): generated files to delete when build steps rerun.
-- `expect` (string array, optional): artifacts that must exist after build/post-steps.
-- `clean` (string array, optional): additional paths removed by `dcr clean` and `--clean`.
-
-Notes for `exclude`/`include`:
-- Supports `*` and `**` glob patterns.
-- If `include` is set, it has priority over `exclude`.
-- Use `include` to re-allow nested paths, for example exclude `src/boot` but allow `src/boot/arch/**`.
-When using glob patterns in `exclude`, DCR converts them internally, so `exclude` globs still work as expected.
-
-### Variable substitution
-
-`cflags`, `ldflags`, and `include` directory entries support the same `{placeholder}` variables
-as build/post steps:
-
-| Variable | Description |
-|---|---|
-| `{profile}` | Build profile (`debug` / `release`) |
-| `{name}` | Package name |
-| `{version}` | Full package version (e.g. `0.2.1`) |
-| `{version_major}` | Major version number |
-| `{version_minor}` | Minor version number |
-| `{version_patch}` | Patch version number |
-| `{version_suffix}` | Version suffix (e.g. `-rc1`) |
-| `{version_suffix_dash}` | Suffix with leading dash (or empty) |
-
-Example:
-
-```toml
-[build]
-cflags = ['-DPROJECT_VERSION="{version}"', '-DVERSION_MAJOR={version_major}']
-```
-
-## Build steps
-
-```toml
-[[build.steps]]
-name = "uic"
-in = "src/ui/*.ui"
-out = "src/ui/{stem}.h"
-cmd = "{uic} {in} -o {out}"
-
-[[build.post_steps]]
-name = "image"
-in = "target/{profile}/boot/*.bin"
-out = "/tmp/image/os-{version}.img"
-cmd = "dd if=/dev/zero of={out} bs=1M count=8"
-```
-
-Step notes:
-- `in` supports glob patterns.
-- If `in` expands to multiple files, `out` must include `{stem}`.
-- Steps run only when inputs are newer than outputs.
-- Variables: `{in}`, `{out}`, `{stem}`, `{cflags}`, `{uic}`, `{moc}`, `{rcc}`, `{profile}`,
-  `{version}`, `{version_major}`, `{version_minor}`, `{version_patch}`, `{version_suffix}`, `{version_suffix_dash}`.
-
-`build.clean` supports `{profile}` and version placeholders (`{version}`, `{version_major}`, ...).
-
-### Profile overrides
-
-Profile tables inherit all values from `[build]`. Any field present in the profile table replaces the base value.
-Array fields (like `cflags`/`ldflags`) are appended to the base array.
-
-Target tables override profile and base settings for specific targets. Full inheritance order:
-1. `[build.<target>.<profile>]`
-2. `[build.<profile>.<target>]`
-3. `[build.<target>]`
-4. `[build.<profile>]`
-5. `[build]`
-
-If custom `cflags` are set (non-empty), default compiler flags are disabled.
-
-```toml
-[build.debug]
-cflags = ["-g3"]
-
-[build.release]
-cflags = ["-O3"]
-ldflags = ["-s"]
-
-# Target-specific overrides (applied after profile)
-[build.linux]
-compiler = "gcc"
-cflags = ["-march=x86_64"]
-
-[build.macos]
-compiler = "clang"
-cflags = ["-arch", "x86_64"]
-
-# Full inheritance example
-[build.linux.release]
-cflags = ["-O3", "-march=native"]  # Overrides profile and base
-
-[build.release.linux]
-ldflags = ["-static"]  # Alternative order
-
-[build.windows.debug]
-compiler = "x86_64-w64-mingw32-gcc"
-cflags = []  # Empty to disable defaults
-
-[build.release]
-inherit = false  # No inheritance, only explicit settings
-```
-
-## Toolchain section
-
-```toml
-[toolchain]
-cc = "clang"
-cxx = "clang++"
-as = "as"
-ar = "ar"
-ld = "ld"
-uic = "uic"
-moc = "moc"
-rcc = "rcc"
-```
-
-## Behavior notes
-
-- Compiler backend is selected by compiler string (`gcc`, `clang`, `cl`, `clang-cl`).
-- Empty or unknown compiler value falls back to clang-like build path.
-- `run` is not allowed for library kinds (`staticlib`, `sharedlib`), `efi`, or `elf`.

-# Dependencies section
-
-DCR supports registry-based dependencies and path dependencies.
-
-## Example
-
-```toml
-[dependencies]
-# Registry dependency
-mylib = "0.1.0"
-# Git dependency
-json = { git = "https://github.com/nlohmann/json", tag = "v3.11.2" }
-# Path dependency
-frecli = { path = "./lib/frecli", include = ["."], lib = ["."], libs = ["frecli"] }
-```
-
-## Supported dependency types
-
-### Registry dependencies
-Defined by name and version string. DCR automatically resolves the package from the configured registry index.
-
-### Git dependencies
-Defined by repository URL and optionally branch, tag, or revision.
-- `git` (string, required): repository URL.
-- `branch`, `tag`, `rev` (string, optional): Git reference.
-
-### Path dependencies
-- `path` (string, required): absolute path or path relative to project root.
-- `include` (string array, optional): include directories inside dependency.
-- `lib` (string array, optional): library directories inside dependency.
-- `libs` (string array, optional): library names for linker.
-
-## Defaults for path dependencies
-
-- If `include` is omitted, DCR tries `<dep>/include`.
-- If `lib` is omitted, DCR tries `<dep>/lib`, then `<dep>/lib64`.
-- If `libs` is omitted, dependency key name is used.
-
-## Validation
-
-- Dependency value must be a string (registry) or a TOML table (path).
-- Registry dependencies use the version string to match versions in the registry.
-- `path` is mandatory for path dependencies.
-- `include`/`lib`/`libs` must be arrays of strings if provided.

-# Compilers & linking
-
-## Compiler backend selection
-
-DCR picks a backend from `build.compiler`:
-
-- contains `clang-cl` -> MSVC backend
-- equals `as` or contains `gas` -> GAS backend (standalone assembler)
-- contains `gcc` or `g++` -> GCC backend
-- contains `clang` or `clang++` -> Clang backend
-- equals `cl` or contains `msvc` -> MSVC backend
-- contains `nasm` -> NASM backend
-- otherwise -> Clang backend fallback
-
-## Compilation model
-
-- Source files are found recursively in `src/` based on `build.language`.
-- `build.roots` and `build.src_disable` can replace the default `src/` root.
-- Mixed language builds use arrays, for example `build.language = ["c", "asm"]`.
-- Each source is compiled to `target/<target>/<profile>/obj/<relative-path>.o` (`.obj` on MSVC, where `<target>` is `native` or target triple).
-- Recompile happens when source mtime is newer than object mtime.
-- `build.exclude` removes paths from source/header collection; `build.include` re-allows matching paths and has priority over `exclude`.
-
-## Default build flags
-
-These flags are applied automatically based on profile and compiler backend.
-
-GCC/Clang:
-
-- `debug`: `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG`
-- `release`: `-O3 -DNDEBUG`
-
-MSVC:
-
-- `debug`: `/Od /Zi /W4 /DDCR_DEBUG /Oy-`
-- `release`: `/O2 /DNDEBUG`
-
-Note: If custom `cflags` are set in `dcr.toml`, default profile flags are disabled to allow full control.
-
-## Platform hint
-
-If `build.platform` is set, DCR passes it as an architecture hint:
-
-- GCC/Clang: `-march=<platform>`
-- MSVC: maps to `/arch:*` for known values (`x86`, `i386`, `i486`, `i586`, `i686`, `sse2`, `avx`, `avx2`)
-
-## Toolchain overrides
-
-If `[toolchain]` is set, DCR uses its values to override compiler/linker tools:
-
-- `cc`, `cxx`, `as` override compilers for C/C++/ASM
-- `ar` overrides the archiver (used for `staticlib`)
-- `ld` overrides the linker (used by GCC/Clang/NASM/GAS backends)
-- `uic`, `moc`, `rcc` override Qt tools used in `build.steps`
-
-Environment overrides (highest priority):
-- `DCR_COMPILER` (all languages)
-- `DCR_CC`, `DCR_CXX`, `DCR_AS`, `DCR_AR`, `DCR_LD`
-- `DCR_DEBUG` enables verbose build logging
-
-## Linking
-
-For `kind = "bin"`:
-
-- Object files are linked into executable artifact.
-- Dependency lib dirs and library names are passed to linker.
-- `build.ldflags` are appended to link command.
-
-For `kind = "staticlib"`:
-
-- Linux/macOS (GCC/Clang): `ar rcs` creates `.a` archive.
-- Windows (MSVC): `lib` creates `.lib` archive.
-
-For `kind = "sharedlib"`:
-
-- Linux (GCC/Clang): `-shared` with output `.so`.
-- macOS (Clang): `-dynamiclib` with output `.dylib`.
-- Windows (MSVC): `/LD` with output `.dll`.

-# Cross-compilation and Targets
-
-DCR supports cross-compilation to different platforms using the `--target` flag. This allows building your project for architectures and operating systems different from the host.
-
-## Basic Usage
-
-```bash
-# Build for a specific target
-dcr build --target x86_64-unknown-linux-gnu --release
-
-# Short names for common platforms
-dcr build --target linux --release    # x86_64-unknown-linux-gnu
-dcr build --target macos --release    # x86_64-apple-darwin
-dcr build --target windows --release  # x86_64-pc-windows-msvc
-
-# Run for a specific target
-dcr run --target linux --release
-```
-
-## Supported Targets
-
-### Short Names
-- `linux` → `x86_64-unknown-linux-gnu`
-- `macos` → `x86_64-apple-darwin`
-- `windows` → `x86_64-pc-windows-msvc`
-
-### Full Target Triples
-DCR supports any valid target triple in the format `<arch>-<vendor>-<os>-<abi>`. Common examples:
-- `x86_64-unknown-linux-gnu`
-- `aarch64-linux-gnu`
-- `x86_64-apple-darwin`
-- `aarch64-apple-darwin`
-- `x86_64-pc-windows-msvc`
-- `i686-pc-windows-gnu`
-
-## Configuration
-
-### Multiple Targets
-
-Configure multiple targets to build simultaneously:
-
-```toml
-[build.targets]
-targets = ["linux", "macos", "windows"]
-
-# Or per profile
-[build.release.targets]
-targets = ["linux", "macos"]
-```
-
-If no `--target` is specified, DCR builds for all targets in `build.targets` (or native if empty).
-
-### Target-Specific Settings
-
-Override settings for specific targets:
-
-```toml
-[build.linux]
-compiler = "gcc"
-cflags = ["-Wall", "-O2"]
-
-[build.macos]
-compiler = "clang"
-cflags = ["-Wall", "-O2", "-arch", "x86_64"]
-
-[build.windows]
-compiler = "x86_64-w64-mingw32-gcc"
-ldflags = ["-static"]
-```
-
-### Target-Specific Toolchain
-
-Configure toolchain per target:
-
-```toml
-[toolchain.linux]
-cc = "gcc"
-ld = "ld"
-
-[toolchain.macos]
-cc = "clang"
-ld = "ld"
-
-[toolchain.windows]
-cc = "x86_64-w64-mingw32-gcc"
-ld = "x86_64-w64-mingw32-ld"
-```
-
-### Target-Specific Run Commands
-
-Use custom run commands per target:
-
-```toml
-[run.linux]
-cmd = "./target/linux/release/myapp"
-
-[run.macos]
-cmd = "open ./target/macos/release/myapp.app"
-
-[run.windows]
-cmd = "wine ./target/windows/release/myapp.exe"
-```
-
-## Workspace and Dependencies Inheritance
-
-Workspace and dependencies sections also support target/profile inheritance:
-
-```toml
-[workspace.linux]
-members = [
-  { name = "lib1", path = "libs/lib1" },
-]
-
-[dependencies.linux]
-sdl2 = { system = true, include = ["/usr/include/SDL2"] }
-
-[dependencies.windows]
-sdl2 = { system = true, include = ["C:/SDL2/include"] }
-```
-
-Order: `workspace.target.profile` → `workspace.profile.target` → `workspace.target` → `workspace.profile` → `workspace`.
-
-Add `inherit = false` to disable inheritance in any section.
-
-Settings are applied in order:
-1. `[build.<target>]`
-2. `[build.<profile>]`
-3. `[build]`
-
-### Toolchain Configuration
-
-For cross-compilation, configure toolchains:
-
-```toml
-[toolchain]
-cc = "aarch64-linux-gnu-gcc"
-cxx = "aarch64-linux-gnu-g++"
-ar = "aarch64-linux-gnu-ar"
-ld = "aarch64-linux-gnu-ld"
-```
-
-## Output Structure
-
-Build outputs are organized by target:
-
-```
-target/
-├── native/
-│   ├── debug/
-│   └── release/
-├── x86_64-unknown-linux-gnu/
-│   ├── debug/
-│   └── release/
-└── aarch64-linux-gnu/
-    ├── debug/
-    └── release/
-```
-
-## Requirements
-
-- Cross-compilation requires appropriate toolchains installed (e.g., `aarch64-linux-gnu-gcc` on Arch Linux).
-- For Windows targets on Linux, install MinGW: `pacman -S mingw-w64-gcc`.
-- For macOS targets on Linux, use `osxcross` or similar.
-
-## Examples
-
-### ARM Linux Build
-
-```bash
-# Install toolchain (Arch Linux)
-pacman -S aarch64-linux-gnu-gcc
-
-# Configure
-echo '[build.aarch64-linux-gnu]
-compiler = "aarch64-linux-gnu-gcc"' >> dcr.toml
-
-# Build
-dcr build --target aarch64-linux-gnu --release
-```
-
-**Note:** If you set `target = "aarch64-linux-gnu"` (or any value) directly under `[build]`, DCR will automatically add `--target=...` to cflags when using clang. You usually don't need to repeat it manually.
-
-### Windows Build on Linux
-
-```bash
-# Install toolchain (Arch Linux)
-pacman -S mingw-w64-gcc
-
-# Configure
-echo '[build.windows]
-compiler = "x86_64-w64-mingw32-gcc"' >> dcr.toml
-
-# Build
-dcr build --target windows --release
-```
-
-## Troubleshooting
-
-- **Toolchain not found**: Ensure the compiler is installed and in PATH, or configure `[toolchain]` in `dcr.toml`. For Arch Linux: `pacman -S aarch64-linux-gnu-gcc` for ARM, `pacman -S mingw-w64-gcc` for Windows cross-compilation.
-- **Linking errors**: Check `ldflags` and library paths for cross-compilation.
-- **Header issues**: Include paths may differ; use target-specific `cflags`.

-# Dependency format
-
-Dependencies are defined in `dcr.toml` under `[dependencies]`.
-
-## Full example (Path)
-
-```toml
-[dependencies]
-fmt = { path = "./third_party/fmt", include = ["include"], lib = ["lib"], libs = ["fmt"] }
-```
-
-## Full example (Git)
-
-```toml
-[dependencies]
-json = { git = "https://github.com/nlohmann/json", tag = "v3.11.2" }
-```
-
-## Field reference
-
-- `path`: local path to dependency root.
-- `git`: URL of Git repository.
-- `branch`: Git branch name.
-- `tag`: Git tag name.
-- `rev`: Git commit SHA.
-- `include`: optional include subpaths (absolute or relative to dep root).
-- `lib`: optional library subpaths (absolute or relative to dep root).
-- `libs`: optional linker library names.
-
-## Common valid compact forms
-
-```toml
-[dependencies]
-mylib = { path = "./libs/mylib" }
-gitlib = { git = "https://github.com/user/repo" }
-# Shortest form for path
-simple = "./libs/simple"
-```
-
-In these forms DCR will try defaults for include/lib dirs and use the dependency name as the linker library name.

-# Local dependencies
-
-## Resolution flow during build
-
-For each dependency in `[dependencies]`, DCR:
-
-1. Resolves `path` (absolute or project-relative).
-2. Resolves include dirs (`include` or default `include`).
-3. Resolves lib dirs (`lib` or defaults `lib`, `lib64`).
-4. Resolves link libs (`libs` or dependency name).
-5. Synchronizes dependency files to `target/<profile>/deps/<dep-name>/`.
-6. Adds include/lib/link options to compile/link commands.
-
-### Profile placeholders
-
-`path`, `include`, and `lib` entries may use `{profile}` which expands to the active profile
-(`debug` or `release`).
-
-## Failure cases
-
-- Dependency path is missing or not a directory.
-- No valid include/lib directories were found.
-- Any configured include/lib path does not exist.
-- Invalid field types in dependency config.

-# Target directory
-
-By default, DCR writes final artifacts to `target/<target>/<profile>/` (where `<target>` is `native` or target triple).
-
-You can override this with `build.target`:
-
-```toml
-[build]
-target = "./dist"
-```
-
-## Behavior
-
-- Binary mode:
-  - Linux/macOS: `<target>/<name>`
-  - Windows: `<target>/<name>.exe`
-- Static library mode:
-  - Linux/macOS: `<target>/lib<name>.a`
-  - Windows: `<target>/<name>.lib`
-
-## Important detail
-
-`build.target` changes only the final artifact location. Object cache and dependency sync directories still use `target/<target>/<profile>/...`.

-# Versioning & lock file
-
-DCR generates `dcr.lock` when dependency resolution succeeds and at least one dependency exists.
-
-## What is stored
-
-- Project entry (`name`, `version`, dependency names).
-- One entry per resolved dependency:
-  - `name`
-  - `version` (from dependency `dcr.toml`, fallback `0.0.0`)
-  - `source` (`path+...`)
-  - `checksum` (SHA-256 over dependency files, excluding nested `target/`).
-
-## Example shape
-
-```toml
-[[package]]
-name = "my-app"
-version = "0.1.0"
-dependencies = ["fmt"]
-
-[[package]]
-name = "fmt"
-version = "1.2.3"
-source = "path+./third_party/fmt"
-checksum = "..."
-```
-
-## Notes
-
-- `dcr.lock` is rewritten on successful dependency resolution.
-- If `[dependencies]` is empty, lock generation is skipped.

+## Registry not found
+
+```
+error: registry not found
+```
+
+**Solution:** Make sure `~/.dcr/config.toml` exists:
+
+```toml
+[[registry]]
+name = "default"
+url = "https://index.dcr.pm"
+```
+
+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`.
+
+## openssl-sys build failed
+
+When building DCR from source:
+
+```
+error: failed to run custom build command for openssl-sys
+```
+
+**Solution:** Install OpenSSL development headers:
+
+```bash
+# Ubuntu/Debian
+sudo apt install libssl-dev
+
+# Fedora
+sudo dnf install openssl-devel
+
+# macOS
+brew install openssl
+```
+
+## 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).
+
+## 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`.

-## Notes
-
-- `run` is unavailable for `build.kind = "staticlib"`, `build.kind = "sharedlib"`, `build.kind = "efi"`, and `build.kind = "elf"`.
-- Build profile flag (`--debug` / `--release`) can be passed in any argument position.
-- Unknown profile flags produce an error.
-- In workspace root, `clean --all` cleans all member projects.
-- `--target` builds/runs for specified target (short names: `linux`, `macos`, `windows`).
-- `--clean` for `build`/`run` removes `target/<target>/<profile>` and paths from `build.clean`.

+
+```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`

-dcr new <name>
-dcr init
-dcr setup
-dcr add <name> <source>(optional)
-dcr build [--debug|--release] [--target <triple>]
-dcr run [--debug|--release]

-
-## Notes on argument parsing
-
-- `build`/`run` parse flags in any order (`--debug|--release`, `--force`, `--clean`, `--verbose`) and reject duplicates.
-- `new` requires exactly one argument.
-- `init` and `--update` do not accept extra arguments.
-- `clean` accepts `--debug|--release` and optional `--all`.
-- `gen` supports `project-info`, `compile-commands`, `vscode`, `clion`.
-- `tree` shows a dependency tree (similar to `cargo tree`).
-- `test` / `tests` runs the project's tests.
-
-## Exit behavior overview
-
-- Successful command execution returns `0`.
-- Validation/build/runtime failures return non-zero status.

-## Validation rules
-
-- `[package]`, `[build]`, `[dependencies]` must exist.
-- Required string fields must be non-empty.
-- `build.kind` must be `bin`, `staticlib`, `sharedlib`, `efi`, or `elf`.
-- Dependency fields `include/lib/libs` must be string arrays when provided.
-- `build.exclude`/`build.include` must be string arrays when provided.
-- `build.roots` must be a string array when provided.
-- `build.src_disable` must be boolean when provided.
-- `build.clean`/`build.generated`/`build.pkg_config`/`build.expect` must be string arrays when provided.
-- `build.debug`/`build.release` must be tables; their `cflags`/`ldflags` must be string arrays.
-- `build.steps`/`build.post_steps` entries must include `name`, `in`, `out`, `cmd`.
-- `build.language` may be a string or array (for example `["c", "c++", "asm"]`).
-- `[build.<profile>]` tables inherit all base values and override any fields they specify.
-  Array fields (like `cflags`/`ldflags`) are appended to the base array.
-
-## Generated defaults (`dcr new` / `dcr init`)
-
-- `package.version = "0.1.0"`
-- `build.language = "c"`
-- `build.standard = "c11"`
-- `build.compiler = "clang"`

-# FAQ
-
-## What commands are available?
-
-`new`, `init`, `build`, `run`, `clean`, `gen`, `--help`, `--version`, `--update`.
-
-## Is `dcr.toml` mandatory?
-
-Yes, for `build`, `run`, and `clean`.
-
-## What source files are compiled?
-
-DCR scans `src/` recursively:
-
-- for C: `*.c`
-- for C++: `*.cpp`, `*.cxx`, `*.cc`
-
-## Can I switch compiler?
-
-Yes. Set `build.compiler` in `dcr.toml` (for example `gcc`, `clang`, `cl`, `clang-cl`).
-
-## How does incremental rebuild work?
-
-It compares source file mtime with object file mtime.
-Header dependencies are tracked too: if an included header changes (or disappears), rebuild is triggered.
-
-## What does `dcr run` do if build fails?
-
-It tries to run an existing binary from the selected profile; if none exists, it reports an error.
-
-## How do I update DCR?
-
-Use `dcr --update` for non-package-managed installs.
-
-If installed through pacman/AUR, update via package manager.

-# Flags & environment
-
-This page summarizes runtime flags and environment variables that affect DCR behavior.
-
-## Build/run flags
-
-Used with `dcr build` and `dcr run`:
-
-- `--debug`: select debug profile.
-- `--release`: select release profile.
-- `--force`: ignore incremental cache checks and rebuild.
-- `--clean`: remove `target/<profile>` and `build.clean` paths before build.
-
-Notes:
-
-- Flags can be passed in any order.
-- Duplicate profile flags are rejected.
-
-## Clean flags
-
-Used with `dcr clean`:
-
-- `--debug` / `--release`: clean only selected profile directory.
-- `--all`: in workspace root, also clean all members.
-
-## Environment variables
-
-Tool selection overrides:
-
-- `DCR_COMPILER` (all languages)
-- `DCR_CC`, `DCR_CXX`, `DCR_AS`, `DCR_AR`, `DCR_LD`
-
-Diagnostics:
-
-- `DCR_DEBUG=1` enables verbose build logging.
-
-## Quick examples
-
-```sh
-# Force full release rebuild
-dcr build --release --force
-
-# Clean before debug run
-dcr run --clean --debug
-
-# Use custom compiler from env
-DCR_CC=clang-18 dcr build --debug
-```

-# Troubleshooting map
-
-Fast mapping from symptom to likely cause and first action.
-
-## `dcr.toml file not found`
-
-Likely cause:
-- you are outside project root (or member root).
-
-First action:
-```sh
-pwd
-ls
-```
-Run DCR from directory that contains `dcr.toml`.
-
-## `Invalid config: missing [package]` / `missing [build]`
-
-Likely cause:
-- incomplete config in root project.
-
-First action:
-- ensure root `dcr.toml` includes `[package]`, `[build]`, and `[dependencies]`.
-- for workspace setups, keep these sections in root and add `[workspace]` additionally.
-
-## `Unknown build flag` or profile-flag errors
-
-Likely cause:
-- typo in flag or duplicate profile flag.
-
-First action:
-```sh
-dcr --help
-```
-Use only supported flags and at most one of `--debug` / `--release`.
-
-## Dependency include/lib path errors
-
-Likely cause:
-- path in `[dependencies]` does not exist.
-
-First action:
-- verify `path`, `include`, `lib` values.
-- if using profile placeholders, confirm expanded paths exist for selected profile.
-
-## `Cannot run library build`
-
-Likely cause:
-- `build.kind` is `staticlib` or `sharedlib`.
-
-First action:
-- switch `build.kind` to `bin`, or set `[run].cmd` if you intentionally need custom run command.
-
-## Build succeeds but output is stale
-
-Likely cause:
-- stale artifacts or generated files from previous runs.
-
-First action:
-```sh
-dcr clean --all
-dcr build --force
-```
-
-## `dcr --update` suggests package manager update
-
-Likely cause:
-- DCR binary is managed by pacman/AUR.
-
-First action:
-```sh
-yay -Syu dcr
-# or
-paru -Syu dcr
-```

-# Workspace guide
-
-`[workspace]` lets you build related DCR projects in dependency order from one root.
-
-## Important rule
-
-Workspace root still needs a valid root project config:
-
-- `[package]`
-- `[build]`
-- `[dependencies]`
-
-`[workspace]` augments that root config; it does not replace required root sections.
-
-## Minimal example
-
-```toml
-[package]
-name = "root-app"
-version = "0.1.0"
-
-[build]
-language = "c"
-standard = "c11"
-compiler = "clang"
-kind = "bin"
-
-[dependencies]
-
-[workspace]
-core = { path = "./modules/core", deps = [] }
-net = { path = "./modules/net", deps = ["core"] }
-app = { path = "./modules/app", deps = ["core", "net"] }
-```
-
-Each member path must point to a directory containing its own `dcr.toml`.
-
-## Build behavior
-
-- Running `dcr build` in workspace root builds members in topological dependency order, then builds the root project.
-
-- Running `dcr clean --all` in workspace root cleans all members too.
-
-- `dcr gen` in workspace root includes root + members in generated outputs.
-
-## Common errors
-
-- `workspace.<name>.path does not contain dcr.toml`:
-  member path is wrong or config is missing.
-- `workspace dependency '<name>' not found`:
-  `deps` references unknown member.
-- `workspace dependency cycle at <name>`:
-  cyclic dependencies in member graph.

+## Compiler Backends
+
+DCR supports 4 compilation backends. Selection is automatic based on file extension.
+
+| 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` | x86/x86_64 assembler |
+
+### 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`
+
+### MSVC
+
+- Supports cl.exe and clang-cl.exe
+- Flags: `/std:`, `/Fo:`, `/Fe:`, `/I`, `/link`
+
+### GAS / NASM
+
+- GAS: `-I`, `-c -o`, `--defsym`
+- NASM: `-I`, `-o`, `-D`, `-f` (format: win64/elf64/macho64/macho32/elf32)
+
+## 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()`
+
+## 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>` |
+
+## 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 |

+
+## 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
+
+For targets containing `none`, `-elf`, `eabi`, or `baremetal`, DCR default flags are disabled (no system include paths, no `-l` libc).
+
+```bash
+dcr build --target aarch64-none-elf
+```
+
+## Target Directory
+
+On Linux with explicit target:
+
+```
+target/<triple>/<profile>/
+```
+
+On macOS/Windows or without target:
+
+```
+target/<profile>/
+```

+
+# Dependencies
+
+## Formats
+
+The `[dependencies]` section supports three formats:
+
+### 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]
+fmt = { git = "https://github.com/fmtlib/fmt", tag = "10.1.1" }
+```
+
+Fields: `git`, `branch`, `tag`, `rev`.
+
+### Table (path)
+
+```toml
+[dependencies]
+mylib = { path = "../mylib" }
+```
+
+## Registry
+
+DCR uses a package registry for dependency lookup by name.
+
+```toml
+# ~/.dcr/config.toml
+[[registry]]
+name = "default"
+url = "https://index.dcr.pm"
+```
+
+Registry priority: order in `config.toml`. The `DCR_INDEX_PATH` variable overrides the path to `index.json`.
+
+## Git dependencies
+
+DCR clones git repositories via `git2`:
+
+- `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)
+
+Cache path: `~/.dcr/git/<hash>/`.
+
+## Path dependencies
+
+Local paths. DCR automatically discovers include and lib directories from the neighbor's `dcr.toml`.
+
+```toml
+[dependencies]
+mylib = { path = "/abs/path/to/lib" }
+mylib = { path = "../relative/path" }
+```
+
+## dcr.lock
+
+Dependency lock file. Contains package names and sources.
+
+Created during `dcr build` when registry dependencies are present. Not updated during `dcr add` — only on the next `dcr build`.
+
+## Resolution process
+
+1. Load all dependencies (registry → git → path)
+2. For path deps: recursively read their `dcr.toml`
+3. For registry deps: search `index.json`
+4. For git deps: clone to cache
+5. Collect `include_dirs`, `lib_dirs`, `libs` for the compiler

+# Platform Support
+
+## Target Triples
+
+DCR normalizes target triples. Short platform names are expanded to full triples.
+
+### Linux
+
+```
+target/<arch>-unknown-linux-gnu/<profile>/
+```
+
+Architectures: `x86_64`, `aarch64` (host-detected).
+
+Artifact type: ELF. Extensions: `.so` (sharedlib), `.a` (staticlib).
+
+### macOS
+
+```
+target/<profile>/
+```
+
+Architectures: `x86_64`, `aarch64` (host-detected).
+
+Extensions: `.dylib` (sharedlib), `.a` (staticlib).
+
+### Windows
+
+```
+target/<profile>/
+```
+
+Architectures: `x86_64`, `aarch64`.
+
+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, member outputs (libraries) are automatically added to include/lib paths of dependent packages.
+
+## 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
+```

+# 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).
