Changelog

[0.7.2] - 2026-06-07 "Исправление Таргетов и Линковки / Target & Linker Fixes"

RU

Добавлено:

• Учтён target_env в default_target_triple() — Linux (gnu/musl) и Windows (msvc/gnu) теперь используют правильное окружение, а не хардкод.

Исправлено:

• Сборка на macOS Apple Silicon падала с _main undefined — --target= теперь передаётся и в ldflags, не только в cflags. default_target_triple() на macOS использует std::env::consts::ARCH вместо хардкода x86_64.
• Бейджи GitHub Stars и GPL-3.0 не рендерились в README — блок бейджей переведён на чистый HTML.

Изменено:

• Вычисление таргета по умолчанию вынесено в общую функцию default_target_triple() — устранено дублирование в build, run, clean.

EN

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 "Мультиархитектурное расширение / The Multi-Arch Expansion"

RU

Добавлено:

• Вывод --help для всех команд с цветным форматированием.
• man-страницы (12 штук в man/man1/) и их установка во всех пакетах.
• Валидация имен проектов в dcr init и dcr new (только ASCII буквы, цифры, _ и -).
• Метаданные documentation и homepage в Cargo.toml.
• Оптимизация сборки: opt-level = "z", LTO, codegen-units = 1, panic = "abort", strip = true.
• Поддержка новых архитектур (i686, armv7, riscv64gc, aarch64) в рабочих процессах и установочных скриптах.
• Сборка пакетов deb и rpm для всех 5 архитектур Linux через cargo-zigbuild.
• Пакеты AUR (dcr-dev, dcr-dev-bin) и сборка Snap в CI.

Изменено:

• Функция validate_package_name стала публичной.
• Команды gen, tree, fmt, setup больше не игнорируют аргументы и используют цветной вывод.
• Инструкция в README изменена с | bash на | sh для POSIX.
• Отключена архитектура Windows 32-bit (GNU) из-за проблем со сборкой.

Исправлено:

• dcr new <invalid-name> создаёт директорию, затем падает — валидация теперь происходит до операций с файлами.
• dcr init создаёт dcr.toml, затем падает при невалидном имени директории — то же исправление.
• Man-страницы отсутствовали после установки — теперь устанавливаются через скрипты установки, пакетные менеджеры и Homebrew.
• Ложное срабатывание на букву диска в Windows — в парсинге файлов зависимостей.
• CRLF \r\n ломает парсер зависимостей — теперь обрабатываются смешанные окончания строк.
• Новая строка после обратного слеша не поглощалась — в обработке escape-последовательностей parse_d_file.

EN

Added:

• --help for all commands with styled headers and usage lines.
• Man pages (12 troff man pages in man/man1/) and their installation across all packaging formats.
• Project name validation in dcr init and dcr new (ASCII letters, digits, _, - only).
• documentation and homepage metadata in Cargo.toml.
• Release profile optimizations (opt-level = "z", LTO, codegen-units = 1, panic = "abort", strip = true).
• Linux i686, armv7, riscv64gc, aarch64 architecture support in release workflows and installation scripts.
• Multi-arch deb and rpm package builds for all 5 Linux architectures via cargo-zigbuild.
• AUR packages (dcr-dev, dcr-dev-bin) and Snap build in CI.

Changed:

• validate_package_name made public and callable from CLI commands directly.
• gen.rs, tree.rs, fmt.rs, setup.rs no longer ignore arguments and use styled output.
• README install instructions changed from | bash to | sh for POSIX compatibility.
• Disabled Windows 32-bit (GNU) target due to build issues.

Fixed:

• dcr new <invalid-name> creates directory then fails — validation now happens before any file operations.
• dcr init creates dcr.toml then fails on invalid directory name — same fix.
• Man pages missing after installation — now installed via install scripts, package managers, and Homebrew.
• Windows drive letter false positive — in dependency file parsing.
• 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] - 2026-06-02

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 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.

[0.6.9] - 2026-05-28

Added:

• Dexoron Packages Index — new standalone CI workflow (.github/workflows/dexoron-packages-index.yml) that automatically updates the dexoron/packages repository indexes after a release. Supports Arch Linux (repo-add), Debian (dpkg-scanpackages), and Fedora (createrepo_c). Triggered by workflow_dispatch or workflow_run on the Release workflow.

• Arch Linux native package (.pkg.tar.zst) build inside the release workflow — builds from source in an archlinux:latest Docker container using a dynamically generated PKGBUILD.

• AUR publish support — new run_aur workflow dispatch input and publish-aur / publish-aur-bin jobs that push PKGBUILD / .SRCINFO to aur.archlinux.org.

Changed:

• Release workflow refactored — Linux packages (deb, rpm, snap, arch) and BSD builds now use strategy.matrix instead of separate jobs. A new publish-dexoron-packages job collects all package artifacts and uploads them to the GitHub Release in one step. Removed standalone build-arch-package, build-snap, build-deb-rpm jobs. The old run_arch_native input is now run_linux_packages.

• Dexoron Packages Index workflow extracted from release.yml into its own file with support for Debian and RPM repository indexes in addition to Arch.

• git2 vendoring — enabled vendored-libgit2 and vendored-openssl features for reproducible CI builds without system libraries.

• cargo-generate-rpm metadata — updated to the current package.metadata.rpm format (uses files table instead of assets array).

Fixed:

• --target=<triple> no longer passed to GCC — the flag is now only injected into cflags when the resolved compiler name contains "clang". GCC rejects this flag with unrecognized command-line option.

• Workspace clean test — removed assertions for member-local target/ directories. Workspace members share the root target/ directory, so their individual src/<name>/target/ is never created.

• Release build test path — corrected expected directory from target/release to target/x86_64-unknown-linux-gnu/release.

[0.6.8] - 2026-05-27

Added:

• build.cxx_standard — separate C++ language standard for .cpp/.cxx/.cc files. When set, overrides build.standard for C++ sources. Example:

  [build]
  language = ["c", "c++"]
  standard = "gnu11"
  cxx_standard = "gnu++17"
  

• Variable substitution for cflags, ldflags, and include directory entries. All {version}, {version_major}, {name}, {profile} and other step variables are now available. Example:

  [build]
  cflags = ['-DPROJECT_VERSION="{version}"']
  

• FreeBSD build support in CI — new run_bsd workflow input and build-bsd job that cross-compiles x86_64-unknown-freebsd via cargo-zigbuild.

Changed:

• License changed from MIT to GPL-3.0-or-later. All source files now carry the GPL-3.0 header. Default license in dcr new / dcr init changed to "GPL-3.0-or-later". README, FAQ, and CONTRIBUTING.md updated accordingly.
• get_list_with_profile_and_target no longer duplicates list values when inherit = true and the profile/target value is identical to the base value.

Fixed:

• Multi-language language array (e.g. ["c", "c++", "asm"]) no longer drops c++ during internal parsing — .cxx/.cpp/.cc source files are correctly discovered and compiled.
• -std= flag is no longer passed to C++ files when only standard (C standard) is configured — uses cxx_standard when available, otherwise skips -std= for C++ sources, avoiding clang error invalid argument '-std=c11' not allowed with 'C++'.
• Object file collision: source files with the same stem but different extensions (e.g. gdt.cxx and gdt.S) no longer overwrite each other. Object filenames now include the original source extension (e.g. gdt.cxx.o, gdt.S.o).
• MSVC backend compile step now detects language per source file extension instead of using the global language field, fixing mixed C/C++ compilation with MSVC.
• Assembler -x flag in unix_cc.rs and gen.rs is now placed before the source file, as required by clang/gcc.
• {version} variables in build.clean are now correctly substituted.

[0.6.7] - 2026-05-26

Added:

• build.kind = "efi" — UEFI PE32+ executable support. Links with -shared -nostdlib -Wl,-dll -Wl,--subsystem,10, output via efi_path() with .efi extension, rejected by dcr run.

• build.kind = "elf" — bare-metal ELF executable support. Uses elf_path() output path, rejected by dcr run, no extra linker flags.

• build.filename and build.extension in dcr.toml — complete control over the final artifact name without relying on package.name. Example:

  [build]
  filename = "KERNEL"
  extension = "EFI"
  

  Produces KERNEL.EFI (works for bin, staticlib, and sharedlib).

• Automatic injection of --target=<build.target> into compiler flags when build.target is set in dcr.toml. This greatly simplifies clang-based cross-compilation (especially for bare-metal targets like aarch64-none-elf).

• Bare-metal targets (containing none, -elf, eabi, baremetal) no longer receive DCR's internal default flags (-g, -Wall, -Wextra, -fno-omit-frame-pointer, -DDCR_DEBUG, etc.). Prevents unwanted sections (.comment, debug info, etc.) that break custom linker scripts when inherit = true.

• build.ldscript in dcr.toml — linker script path passed as -T <path> to the linker. Essential for bare-metal/embedded/freestanding targets.

• dcr build --verbose — prints compiler/linker command lines (also works with DCR_DEBUG env var).

• dcr add <name> without a source argument — if a registry is configured, DCR looks up the package by name and adds it as a version dependency.

Fixed:

• build.target declared in dcr.toml is now correctly used as the default target even when --target is not passed on the command line (previously the host target was always forced for config resolution).
• dcr run with --target or build.target now correctly finds the binary in the arch-specific target directory.
• dcr run checks profile-specific build.{profile}.kind before rejecting library builds (previously only checked build.kind).
• dcr clean now reads build.target from dcr.toml when no --target flag is given.
• Linux: target directory is now consistent — target/<arch>-unknown-linux-gnu/<profile>/ (no stale target/<profile>/).
• dcr.lock is now populated with all resolved dependencies (registry, path, git) instead of being always empty.
• Git dependencies are now properly recognized and recorded in dcr.lock.
• is_registry_dep correctly identifies version-based registry dependency tables ({ version = "..." }) and rejects tables with unknown keys.
• dcr test accepts --debug/--release flags (defaults to debug profile instead of always release).
• Build fingerprint cache (build_cache_path) now includes target_dir — different targets no longer share a single cache entry.
• object_path no longer hardcodes the src/ prefix — works correctly with custom build.roots (e.g. roots = ["lib"]).
• dcr update now generates .exe candidates for all Windows targets, not just x86_64-pc-windows-msvc.
• Compiler existence is verified before starting the build (clear error if compiler is not found in PATH).
• Consolidated duplicate OUTPUT_MUTEX definitions — MSVC backend now uses the shared mutex from common.rs.
• Registry cache root directory is created if missing (prevents cryptic errors when ~/.dcr/ does not exist).

Changed:

• openssl dependency is now conditional (cfg(not(windows))) — no longer pulled in on Windows, fixing Windows CI builds that lack Perl Locale::Maketext::Simple. On Linux (including musl cross-compilation) the vendored OpenSSL build is unchanged.

[0.6.6] - 2026-05-18

Fixed:

• Path dependencies now work correctly: dcr add stores them as { path = "./..." } tables, is_registry_dep properly distinguishes registry strings from path/git strings, and deps/mod.rs resolves both table-form and legacy string-form path dependencies
• Registry dependency paths no longer hardcoded to project_root/dcr-index; now use package_root_from_registry_info() which resolves relative to the registry cache root (~/.dcr/)
• Registry dependencies are now actually built: build_project_at() is called when include_dir or lib_dir is missing

Added:

• SIGINT/Ctrl+C handler via ctrlc crate — dcr build now checks BUILD_INTERRUPTED flag at key points and aborts cleanly
• utils/build.rs — extracted shared utilities: parse_version_info, normalize_target_os, resolve_compiler, primary_language, resolve_pkg_config_flags and config helpers. Eliminates code duplication between cli/build.rs, cli/run.rs, cli/clean.rs, cli/gen.rs
• utils/fs.rs::with_dir — extracted common directory-scoped execution
• run_command_sync_output in builder/common.rs with global OUTPUT_MUTEX — synchronized compiler output across all backends (unix_cc, gas, nasm, msvc)
• New helper functions in deps/register.rs: get_registry_cache_root, package_root_from_registry_info, registry_include_dir, registry_lib_dir, path_from_string_dep
• Unit tests for register.rs (is_registry_dep, package_root_from_registry_info), deps/mod.rs (path_dep_path, push_default_lib_dirs), utils/build.rs (normalize_target_os, parse_version_info)
• dcr tree command — visual dependency tree viewer (similar to cargo tree)

Removed:

• Removed unused dependencies indicatif and console from Cargo.toml

[0.6.5] - 2026-05-13

Added:

• New dependency registry system
• Package type support (lib, app, none) in dcr.toml
