# Зависимости
|
||
|
||
## Форматы
|
||
|
||
В секции `[dependencies]` поддерживаются три формата:
|
||
|
||
### Строка (реестр)
|
||
|
||
```toml
|
||
[dependencies]
|
||
fmt = "10.1.1"
|
||
spdlog = "^1.12"
|
||
catch2 = ">=3.0,<4.0"
|
||
```
|
||
|
||
Строка версии используется без изменений для поиска в реестре.
|
||
|
||
### Табличный (git)
|
||
|
||
```toml
|
||
[dependencies]
|
||
fmt = { git = "https://github.com/fmtlib/fmt", tag = "10.1.1" }
|
||
```
|
||
|
||
Поля: `git`, `branch`, `tag`, `rev`, `features`.
|
||
|
||
### Табличный (path)
|
||
|
||
```toml
|
||
[dependencies]
|
||
mylib = { path = "../mylib" }
|
||
```
|
||
|
||
## Реестр
|
||
|
||
## RegistryDCR использует реестр пакетов для поиска зависимостей по имени.```toml
|
||
# ~/.dcr/config.toml
|
||
[registry]
|
||
main = { url = "https://github.com/dcr-ports/dcr-index", priority = 1 }
|
||
```
|
||
|
||
```toml
|
||
# ~/.dcr/config.toml
|
||
[registry.default]
|
||
url = "https://index.dcr.pm"
|
||
priority = 1
|
||
```
|
||
|
||
Приоритет реестра: порядок в файле `config.toml`. Переменная `DCR_INDEX_PATH` переопределяет путь к index.json.
|
||
|
||
## Git-зависимости
|
||
|
||
Git dependencies are parsed and recorded in `dcr.lock`. DCR supports specifying branch/tag/rev for git sources:
|
||
|
||
* `branch` — переключиться на ветку
|
||
* `tag` — переключиться на тег
|
||
* `rev` — переключиться на конкретный коммит
|
||
* `features` — флаги функций (проанализированы, но не влияют на сборку)
|
||
|
||
## Path dependencies
|
||
|
||
Local paths. 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
