-## Quick start
-
-```bash
-cargo build --release && ./target/release/dcr setup
-```
-
-## Pre-PR (CI) gate
-
-```bash
-cargo fmt --all --check
-cargo clippy --all-targets --all-features -- -D warnings
-cargo check --all-targets --all-features
-cargo test
-```
-
-CI (`.github/workflows/ci.yml`) runs fmt, clippy, check — **not** tests.
-
-## Tests
-
-- Integration tests in `tests/` build the dcr binary and run it in temp dirs under `sandbox/cli-tests/` (gitignored).
-- Some tests **skip** if no C compiler (`gcc`/`clang`/`cc`) is found at runtime.
-- Compiler can be overridden via `DCR_COMPILER` or `DCR_CC` env vars.
-- Tests use `$CARGO_BIN_EXE_dcr` when available, else `target/debug/dcr`.
-
-## Architecture
-
-- **Single Rust package** (edition 2024), not a workspace. Only one binary: `dcr`.
-- **Entrypoint**: `src/main.rs` — matches `args[1]` against command names.
-- **Compiler backends** in `src/core/builder/`: `unix_cc` (gcc/clang), `msvc` (cl/clang-cl), `gas`, `nasm`. Dispatched by matching compiler name string.
-- **Config**: `dcr.toml` (per-project), `~/.dcr/config.toml` (registry), `~/.dcr/index.json` (index). Defaults: `language=c`, `standard=c11`, `compiler=clang`, `kind=bin`.
-- **`build.rs`** embeds `TARGET` as `DCR_TARGET` env var (shown in `--version`).
-- **CLI output** must be in English. Use `utils::log` for messaging.

-## Key commands
-
-| Command | Notes |
-|---|---|
-| `dcr new <name>` | Creates project dir |
-| `dcr init` | Init from CWD (must be empty) |
-| `dcr build [--debug\|--release] [--target <triple>]` | Default profile: `--debug` |
-| `dcr run [--debug\|--release]` | Only for `kind = "bin"` |
-| `dcr clean [--debug\|--release] [--all]` | `--all` for workspace roots |
-| `dcr tree` | Dependency tree viewer |
-| `dcr test [--init]` | Runs/test project tests |
-| `dcr gen <vscode\|clion\|compile-commands>` | IDE integration |
-| `dcr --update` | Self-update from GitHub Releases |
-
-## Cross-compilation
-
-`--target` accepts short names (`linux`, `macos`, `windows`) or full triples. In CI, Linux cross-builds use `cargo-zigbuild`. When `build.target` is set in `dcr.toml`, DCR auto-injects `--target=<value>` into cflags (clang). Bare-metal targets (containing `none`/`-elf`/`eabi`/`baremetal`) skip DCR's default compiler flags.
-
-## Dependencies (Cargo)
-
-reqwest (blocking+json+rustls-tls), serde, toml, git2, openssl (vendored), self-replace, sha2, ctrlc.

-## [0.7.0] - 2026-05-28
+## [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:
 
-- **FreeBSD, OpenBSD, NetBSD, DragonflyBSD target support** — full platform routing and dynamically generated target triples.
+- **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`.

 ## Why DCR?
 
 - **No boilerplate** — one config file, predictable structure
-- **Cargo-like workflow** — `build`, `run`, `clean`, `test`, `add`
+- **Cargo-like workflow** — `build`, `run`, `clean`, `test`, `add`, `fmt`
 - **Cross-compilation** — full target triple support with short names
 - **IDE integration** — VS Code, CLion, `compile_commands.json` out of the box
 - **Dependencies** — path, git, and registry-based with lock file
+- **Man pages** — `man dcr` and per-command pages (`man dcr-build`, `man dcr-new`, etc.)

-# DCR TODO.md
-
-Priority list of tasks to turn DCR into a true Cargo killer for C/C++ developers.
-
-## 🔥 High Priority (Next Releases)
-
-- [x] **Git dependencies support**  
-  `git = "https://github.com/user/repo.git#branch"` and `git = "..."@tag`
-- [ ] **Conan and vcpkg integration**  
-  Automatic download, installation and linking of packages
-- [ ] **Full freestanding / embedded support**  
-  `-nostdlib`, linker scripts, bare-metal targets (i686-elf, aarch64-none-elf, etc.)
-- [ ] **EFI support**  
-  Dedicated platform configuration for EFI targets
-- [ ] **Custom project name**  
-  Override binary name in `dcr.toml`
-- [ ] **Custom build steps / targets**  
-  Ability to define custom pre-build, post-build, codegen steps in `dcr.toml`
-- [ ] **Improved mixed C/C++/ASM projects**  
-  Better handling of `.S` and `.asm` files with correct flags
-- [ ] **dcr publish + official package registry**  
-  Publish and fetch your own libraries easily
-
-## ✅ Medium Priority
-
-- [ ] **Static analysis** (`dcr check`)  
-  Integration with clang-tidy, cppcheck, include-what-you-use
-- [ ] **Linter + Formatter** (`dcr fmt`, `dcr lint`)
-- [ ] **Hot reload / Live reload** for applications (raylib, SFML, SDL, etc.)
-- [ ] **Better cross-compilation experience**  
-  Ready-to-use toolchains + automatic download
-- [ ] **Linker script support** + direct linker control
-- [ ] **Workspaces improvements**  
-  Per-member include directories, selective builds, better dependency graph
-- [ ] **Build-time code generation**  
-  Support for protobuf, flatbuffers, Qt moc, custom generators
-
-## 📌 Low Priority / Nice to Have
-
-- [ ] Support for Meson and Ninja as alternative backends
-- [ ] Dockerfile generation (`dcr docker init`)
-- [ ] First-class Windows MSVC support (currently works but rough)
-- [ ] Documentation generation (`dcr doc`)
-- [ ] Sanitizers integration (`dcr sanitize`)
-- [ ] Benchmarks and comparison with CMake/Meson
-- [ ] C++20 modules support (when it becomes stable)
-
-## 🧠 Future Ideas
-
-- Official DCR package registry (dcrhub)
-- GUI wrapper (dcr-gui)
-- Plugin system
-- Toolchain manager (like rustup)
-- Zig as alternative compiler
-- deb/rpm/flatpak/AppImage packaging support
-
----
-
-**Currently in progress:**
-
-- ...
-
-**Completed in recent releases:**
-
-- Workspaces
-- Cross-compilation
-- IDE config generation (VS Code, CLion, compile_commands.json)
-- Self-update (`dcr --update`)
-- Header tracking

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

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

-
-## 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.

-# 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 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`

-- **`.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)

-1. Validates arguments (`<name>` is required, only one name is allowed).
-2. Creates `<name>/`.
-3. Creates `<name>/dcr.toml`.
-4. Sets `package.name = "<name>"`.

-```
-
-Behavior:
-
-1. Requires current directory to be empty.

-# 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
-```
-
-## Behavior
-
-1. Validates `dcr.toml`.
-2. Reads `package.name`, `build.kind`, and optional `build.target`.
-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).

-- `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:

-
-- `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.

-## 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.

-- `repository` (string, optional): source repository URL.
-- `readme` (string, optional): path to README file.
-- `keywords` (array of strings, optional): project keywords.
-- `categories` (array of strings, optional): project categories.
-
-## Notes
-
-- Empty `name` or `version` makes config invalid.
-- `dcr new` sets `name` from the passed project name.
-- `dcr init` sets `name` from current directory name.
-- If `type = "lib"`, DCR generates `include/` and `lib/` directories in the target path, copying public headers and built libraries.

-# 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`.

-## 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.

-# Installation
-
-## Option 1: Install via script
-
-### Linux/macOS
-
-```sh
-curl -fsSL https://dcr.dexoron.su/install.sh | bash
-```
-
-Alternative with `wget`:
-
-```sh
-wget -qO- https://dcr.dexoron.su/install.sh | bash
-```
-
-### Windows (PowerShell)
-
-```powershell
-powershell -ExecutionPolicy ByPass -c "irm https://dcr.dexoron.su/install.ps1 | iex"
-```
-
-## Option 2: Build from source
-
-```sh
-git clone https://github.com/dexoron/dcr.git
-cd dcr
-cargo build --release
-mkdir -p ~/.local/bin
-ln -sf "$PWD/target/release/dcr" ~/.local/bin/dcr
-```
-
-## Option 3: Arch Linux (AUR)
-
-```sh
-yay -S dcr
-```
-
-(You can also use `paru` or other AUR helpers.)
-
-## Verify installation
-
-```sh
-dcr --version
-```
-
-Expected format:
-
-```text
-dcr <version> (<target>)
-```
-
-## Update policy
-
-- If DCR was installed from GitHub releases, scripts, or manual build: use `dcr --update`.
-- If DCR is managed by `pacman/AUR`: update via package manager. On Linux, `dcr --update` detects pacman-owned binaries and prints a package-manager hint.

+# Installation
+
+## dcrup (recommended)
+
+Install and switch DCR versions (stable / dev / night, pin `0.8.2`, optional build from source).
+
+### Linux / macOS / BSD / Windows (bash)
+
+```sh
+curl -fsSL https://sh.dcr-tool.ru | sh -s -- self-install
+export PATH="$HOME/.dcr/bin:$PATH"
+dcrup install stable
+```
+
+Non-interactive install of DCR in one shot:
+
+```sh
+curl -fsSL https://sh.dcr-tool.ru | sh -s -- install stable
+export PATH="$HOME/.dcr/bin:$PATH"
+```
+
+### Windows (PowerShell)
+
+```powershell
+irm https://ps1.dcr-tool.ru | iex
+# or download then run:
+# irm https://ps1.dcr-tool.ru -OutFile dcrup.ps1
+# powershell -File .\dcrup.ps1 self-install
+# $env:Path += ";$env:USERPROFILE\.dcr\bin"
+dcrup install stable
+```
+
+Optional cmd bootstrap (if you prefer `curl` of the cmd shim):
+
+```bat
+curl -fsSL -o dcrup.cmd https://cmd.dcr-tool.ru
+```
+
+After `self-install`, the command is **`dcrup`** (no `.sh` / `.ps1`): shims live in `~/.dcr/bin` (Unix) or `%USERPROFILE%\.dcr\bin` (Windows `dcrup.cmd`).
+
+### Common dcrup commands
+
+```sh
+dcrup install stable              # latest stable prebuilt
+dcrup install 0.8.2               # pin → 0.8.2@stable
+dcrup install 0.8.2@dev
+dcrup install stable --libc musl  # Linux: musl asset (default: gnu)
+dcrup install stable --build      # cargo build --features archive
+dcrup install night               # always build from branch dev HEAD
+dcrup default 0.8.2
+dcrup update

+  dcr.toml
+  src/
+    boot.asm      # boot sector (512 bytes)
+    kernel.asm    # payload

+
+For multiple flat artifacts, use a **workspace** (one member per binary) or separate packages; a single `flat-bin` package produces one binary per source stem.
+
+## Boot package (`flat-bin`)
+
+```toml
+[package]
+name = "boot"
+version = "0.1.0"
+
+[build]
+language = "asm"

+- `format`: `fat12`, `fat16`, or `fat32`
+- `size`: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default ~1.44 MiB)
+- `bootsector`: written only when `offset` is omitted or `0`
+- `from` may be a glob; `{profile}` is substituted in paths
+
+## C kernel → flat binary
+
+```toml
+[build]
+language = "c"
+compiler = "clang"
+kind = "flat-bin"
+freestanding = true
+filename = "kernel"
+extension = "bin"
+ldflags = ["-T", "linker.ld"]
+```
+
+Pipeline: objects → temporary linked ELF → `objcopy -O binary` → `kernel.bin`. Requires `objcopy` / `llvm-objcopy` in PATH.
+
+## Other assemblers
+
+| Tool | Notes |
+|------|--------|
+| **FASM** | Write `format binary` in the source; DCR writes `<stem>.bin` directly |
+| **GAS** | Assemble `.s` → obj → `objcopy -O binary` |
+| **LLC** | `language = "llvm_ir"` → obj → objcopy |
+| **MASM** | COFF obj → objcopy (needs binutils/LLVM objcopy) |
+
+## Notes
+
+- Single-file `roots` are supported: `roots = ["src/boot.asm"]`.
+- `--force` re-runs `build.steps` / `build.post_steps` as well as recompilation.
+- Prefer `kind = "elf"` if you need a relocatable ELF kernel without stripping to raw binary.

-- `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.

-# 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

-# 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.

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

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

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

+
+## Per-language overrides: `[build.c]`, `[build.cxx]`, `[build.asm]`, `[build.llvm_ir]`
+
+Each language can have its own table that overrides the flat `[build]` settings:
+
+```toml
+[build]
+compiler = "clang"
+standard = "c11"
+
+[build.c]
+standard = "c23"
+compiler = "gcc"
+
+[build.cxx]
+standard = "c++23"
+compiler = "g++"
+
+[build.asm]
+compiler = "nasm"
+flags = ["-felf64"]
+
+[build.llvm_ir]
+compiler = "llc"
+```
+
+The flat `[build]` acts as fallback; per-language tables take precedence for their language.
+
+Example:
+
+```toml
+[build]
+language = "c++"
+standard = "c23"
+cxx_standard = "c++23"
+compiler = "clang"
+kind = "sharedlib"

+
+## [run]
+
+```toml
+[run]
+cmd = "./target/{profile}/{name}"
+```
+
+Substitutions:
+- `{version}` — package version
+- `{version_major}`, `{version_minor}`, `{version_patch}`, `{version_suffix}`, `{version_suffix_dash}` — version parts
+- `{profile}` — debug / release
+- `{name}` — package name
+
+Default `cmd` = `./target/{profile}/{name}` (macOS/Windows) or `./target/<triple>/<profile>/<name>` (Linux).
+
+## [workspace]
+
+See [workspaces](/docs/reference/workspaces).
+
+## [archive]
+
+Optional post-build step: format a FAT volume and copy built artifacts into a disk image. Runs after a successful package build (and after workspace member builds that define `[archive]`).
+
+Requires DCR built with the `archive` Cargo feature (`cargo build --features archive`). Release binaries include this feature.
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `output` | yes | Image path relative to project root (`{profile}` allowed) |
+| `format` | yes | `fat12`, `fat16`, or `fat32` |
+| `size` | no | Image size: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default `1474560` ≈ 1.44 MiB) |
+| `offset` | no | Byte offset of the FAT volume inside the image (default `0`) |
+| `label` | no | Volume label (max 11 chars, default `VOLUME`) |
+| `bootsector` | no | Path to a 512-byte boot sector written at offset 0 when `offset` is 0 (`{profile}` allowed) |
+| `layout` | no | List of `{ from, to }` entries (files or globs → path inside the volume) |
+
+```toml
+[archive]
+output = "target/{profile}/disk.img"
+format = "fat12"
+size = "1440K"
+label = "MYOS"
+bootsector = "target/{profile}/boot.bin"
+
+[[archive.layout]]
+from = "target/{profile}/kernel.bin"
+to = "KERNEL.BIN"
+
+[[archive.layout]]
+from = "assets/*"
+to = "/"
+```
+
+Typical pairing with `kind = "flat-bin"` (NASM `-f bin`) for bootloaders and pure-ASM OS images.
+
+## `flat-bin` (kind)
+
+Produces a raw binary (default extension `bin`) for boot sectors, kernels, and freestanding payloads.
+
+### Assemblers
+
+| Tool | Language / compiler | How flat-bin is produced |
+|------|---------------------|--------------------------|
+| NASM | `language = "asm"`, `compiler = "nasm"` | `-f bin` → `<stem>.bin` |
+| FASM | `compiler = "fasm"` | direct write (use `format binary` in source) |
+| GAS | `compiler = "as"` / `"gas"` | assemble → `objcopy -O binary` |
+| MASM | `compiler = "ml"` / `"ml64"` | assemble → `objcopy -O binary` |
+| LLC | `language = "llvm_ir"`, `compiler = "llc"` | `-filetype=obj` → `objcopy -O binary` |
+
+```toml
+[build]
+language = "asm"
+compiler = "nasm"
+kind = "flat-bin"
+extension = "bin"
+roots = ["src/boot.asm"]
+```
+
+### C / C++
+
+Compile all sources, link with `-nostdlib -static` (plus your `ldflags` / `ldscript`), then convert the intermediate ELF/PE with `objcopy -O binary` to `<filename|name>.bin`.
+
+```toml
+[build]
+language = "c"
+compiler = "clang"
+kind = "flat-bin"
+freestanding = true
+filename = "kernel"
+extension = "bin"
+ldscript = "linker.ld"
+ldflags = ["-T", "linker.ld"]
+```
+
+Notes:
+
+- Multi-file **ASM** packages emit one `<stem>.bin` per source; **C/C++** emit a single project binary.
+- `objcopy` tools tried in order: `llvm-objcopy`, `objcopy`, `gobjcopy`.
+- Incompatible with `build.qt = true`.
+- `dcr run` rejects `flat-bin` (not a host executable).

+
+# Dependencies
+
+## Formats
+
+The `[dependencies]` section supports 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.default]
+url = "https://index.dcr.pm"
+priority = 1
+```
+
+Registry priority: order in `config.toml`. The `DCR_INDEX_PATH` variable overrides the path to `index.json`.
+
+## Git dependencies
+
+Git dependencies are parsed and recorded in `dcr.lock`. DCR supports specifying branch/tag/rev for git sources:
+
+- `branch` — switch to a branch
+- `tag` — switch to a tag
+- `rev` — switch to a specific commit
+- `features` — feature flags (parsed, but does not affect build)
+
+## Path dependencies
+
+Local paths. 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" }
+```
+
+*Note: Header resolution automatically checks the packaged `target/include` directory of path dependencies, ensuring consumer packages can find headers from compiled static or dynamic libraries.*
+
+## 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

+DCR normalizes target triples. Short platform names are expanded to full triples.
+
+### Linux
+
+```
+target/<arch>-unknown-linux-<env>/<profile>/
+```
+
+Architectures: `x86_64`, `aarch64`, `i686`, `armv7`, `riscv64` (host-detected).
+Environments: `gnu` (default), `musl`.
+
+Artifact type: ELF. Extensions: `.so` (sharedlib), `.a` (staticlib).
+
+### macOS
+
+```
+target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
+```
+
+Architectures: `x86_64`, `aarch64` (host-detected).
+
+Extensions: `.dylib` (sharedlib), `.a` (staticlib).
+
+### Windows
+
+```
+target/<profile>/ (default) or target/<triple>/<profile>/ (with target)
+```
+
+Architectures: `x86_64`, `aarch64`.
+Environments: `msvc` (default), `gnu` (MinGW).
+
+Extensions: `.exe` (bin), `.lib` (staticlib), `.dll` (sharedlib), `.efi` (UEFI).

+```
+target/<arch>-unknown-<os>/<profile>/
+```
+
+Supported systems: `freebsd`, `openbsd`, `netbsd`, `dragonfly`.
+
+## Host Detection
+
+DCR uses `std::env::consts::ARCH` and `std::env::consts::OS` for host platform detection. Used as fallback when `target` is not specified.

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

+## 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).
