Changelog

[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.

[0.7.4] - 2026-06-17 "Qt Поддержка, Linting и Рефакторинг Архитектуры / Qt Support, Linting, & Architecture Refactor"

RU

Добавлено:

• Нативная поддержка Qt — добавлена автоматическая обработка мета-объектов (MOC, UIC, RCC) при включении build.qt = true в dcr.toml.

• Команда dcr lint — статический анализ C/C++ через clang-tidy. Поддерживает --fix для автоматического исправления. Уважает build.roots и build.src_disable из конфига.

• Три новых ассемблерных бэкенда:

  • MASM (compiler = "ml" / "ml64") — Microsoft Macro Assembler.
  • FASM (compiler = "fasm") — Flat Assembler.
  • LLVM IR (compiler = "llc") — компиляция .ll → объектный файл.

• Общий ASM-пайплайн — линковка и архивирование вынесены в core/builder/asm.rs. Новый ассемблерный бэкенд теперь пишется за ~30 строк.

• Утилиты для файловой системы — to_hex() и home_dir() вынесены в utils/fs.rs.

• Утилиты для сборки — normalize_target(), normalize_kind(), normalize_platform(), default_profile_flags() вынесены в utils/build.rs.

• Утилиты для бэкендов — asm_lang_flag(), source_extensions(), elapsed_secs() добавлены в core/builder/common.rs.

• Полноценная автоматизация Bare-Metal / Freestanding — добавлен конфигурационный флаг build.freestanding = true. При его включении (или при обнаружении bare-metal таргета) DCR автоматически инжектирует флаг -ffreestanding на этапе компиляции, а также -nostdlib и -static на этапе линковки.

• Оптимизация артефактов (LTO и Strip) — в dcr.toml добавлены параметры build.lto (авто-инжекция флага -flto для компилятора и линкера) и build.strip (автоматическое отсекание отладочной информации через флаг -s линкера).

• Контроль многопоточности сборки — добавлен параметр build.codegen-units, позволяющий жестко ограничить максимальное количество параллельных потоков сборки для кастомного движка parallel_build.

• Управление паникой (Panic Abort) — добавлен параметр build.panic = "abort". Для C++ проектов он автоматически отключает генерацию таблиц раскрутки стека и исключений через флаги -fno-exceptions, -fno-unwind-tables и -fno-asynchronous-unwind-tables.

Изменено:

• Интеллектуальные дефолтные флаги (DCR Defaults) — генерация дефолтных флагов оптимизации (-O3/-O0), отладки (-g) и предупреждений (-Wall -Wextra) теперь автоматически отключается для bare-metal и freestanding целей, если пользователь переопределил build.cflags.
• Глобальный вынос bare-metal детектора — функция is_bare_metal_target вынесена в общие утилиты src/utils/build.rs для сквозного использования в конвейере сборки.
• Рефакторинг архитектуры:
  • src/config.rs переименован в src/templates.rs.
  • Начата консолидация конфигурационной логики и оркестрации сборки.

EN

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 "Оптимизация Зависимостей и VCS / Dependency Optimization & VCS"

RU

Добавлено:

• Параметр --vcs для команд new и init — добавлена возможность явно указывать систему контроля версий через --vcs <git|none>.
• Интеграция Git-информации в --version — утилита теперь выводит текущий короткий хэш коммита и суффикс -dirty, если в репозитории DCR есть незакоммиченные изменения.
• Автоматическая генерация .gitignore — при инициализации Git-репозитория автоматически создается файл .gitignore с исключением директории /target.
• Защита от вложенных репозиториев — автоматическая инициализация Git теперь пропускается, если dcr new или dcr init запускаются внутри уже существующего Git-репозитория.
• Тесты для верификации VCS — добавлены интеграционные тесты new_vcs_options_work и init_vcs_options_work для проверки логики инициализации репозиториев.

Изменено:

• Полный отказ от библиотеки git2 — работа с Git (клонирование зависимостей, инициализация VCS, проверка статуса) переведена на вызовы системного git через Command. Это облегчает сборку проекта и убирает необходимость в фичах vendored и openssl.
• Миграция с reqwest на ureq — в модуле обновления (flag_update.rs) тяжелый reqwest заменен на легковесный синхронный клиент ureq 2.10, что уменьшило оверхед и размер итогового бинарника.

EN

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 "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
