# codex-git-utils
Helpers for interacting with git, including patch application. The crate also
exposes a lightweight baseline API for internal directories that use git only
as a resettable diff mechanism: `ensure_git_baseline_repository` preserves a
usable `root/.git` baseline or creates one when it is missing or unusable,
`reset_git_repository` replaces `root/.git` with a fresh one-commit baseline,
and `diff_since_latest_init` returns structured file changes plus a unified
diff from that baseline to the current directory contents.
```rust,no_run
use std::path::Path;
use codex_git_utils::{apply_git_patch, ApplyGitRequest};
let repo = Path::new("/path/to/repo");
// Apply a patch (omitted here) to the repository.
let request = ApplyGitRequest {
cwd: repo.to_path_buf(),
diff: String::from("...diff contents..."),
revert: false,
preflight: false,
};
let result = apply_git_patch(&request)?;
```
