gitr

Async typed git CLI wrapper for agents and automation.

Why gitr?

gitr shells out to the git binary and provides structured types, typed errors, and porcelain parsing. It is the only pure-Rust approach with full feature coverage for AI agent workflows.

Quick start

Add to your Cargo.toml:

[dependencies]
gitr = "0.3"

Open a repository

use gitr::Repository;

#[tokio::main]
async fn main() -> Result<(), gitr::Error> {
    let repo = Repository::open(".").await?;
    let branch = repo.current_branch().await?;
    println!("On branch: {branch}");
    Ok(())
}

Check status and commit

use gitr::Repository;

#[tokio::main]
async fn main() -> Result<(), gitr::Error> {
    let repo = Repository::open(".").await?;

    // Ensure clean working tree
    repo.ensure_clean().await?;

    // Stage, commit, push
    repo.add_all().await?;
    let sha = repo.commit("feat: agent work", &[]).await?;
    repo.push("origin", "main", false).await?;

    println!("Committed {sha}");
    Ok(())
}

Worktree workflow

use gitr::Repository;

#[tokio::main]
async fn main() -> Result<(), gitr::Error> {
    let repo = Repository::open(".").await?;

    repo.worktree_add("/tmp/wt-1", "feature-x").await?;
    let wt = repo.open_worktree("/tmp/wt-1").await?;

    wt.add_all().await?;
    wt.commit("feat: agent work in worktree", &[]).await?;

    repo.worktree_remove("/tmp/wt-1", false).await?;
    Ok(())
}

Read-only merge conflict detection

use gitr::Repository;

#[tokio::main]
async fn main() -> Result<(), gitr::Error> {
    let repo = Repository::open(".").await?;

    let result = repo.merge_tree("main", "feature-x").await?;
    if result.has_conflicts {
        println!("Conflicts: {:?}", result.conflict_files);
    } else {
        println!("Clean merge");
    }
    Ok(())
}

API overview

Repository

• Status: ensure_clean, status, changed_files, conflicted_files, untracked_files
• Branch: current_branch, branch_create, branch_delete, branch_exists, checkout, default_branch
• Commit & Push: commit, push, push_force, fetch, remote_url
• Worktree: worktree_add, worktree_remove, worktree_list, open_worktree
• Merge & Rebase: merge, merge_tree, rebase, rebase_continue, rebase_abort
• Stash: stash, stash_pop
• Diff: diff, diff_files
• Stage: add, add_all

Errors

gitr::Error (GitError) provides typed variants for every failure mode:

• NotARepo — path lacks .git
• GitNotFound — git binary not in PATH
• CommandFailed — non-zero exit with stdout/stderr captured
• Timeout — command exceeded time budget (default 60s)
• Dirty — working tree has changes
• BranchExists / BranchNotFound
• WorktreeExists
• MergeConflicts
