✨ Main features

• Customizable rules: Configure rules to enforce Conventional Commits, length limits, Gitmoji usage, and more.

• Clear error reporting: Provides detailed error reporting, making fixing commit messages straightforward and educational.

• Seamless integration: As a single binary, git-sumi easily integrates into your existing workflow with minimal setup. You can even use the GitHub Action to lint your commits (or PR titles) without installing anything.

🚀 Quick start

Install git-sumi:

# From cargo.
cargo install git-sumi

# From pip.
uv tool install git-sumi
pipx install git-sumi
pip install git-sumi

# Chocolatey (Windows).
choco install git-sumi

Create a base sumi.toml configuration file in your repository:

git sumi --init

Edit sumi.toml with your project's rules:

# Rule: Use the imperative mood in the description.
# Example: 'Fix bug' instead of 'Fixed bug'.
imperative = true

# Rule: Body line length limit.
# A value of 0 disables the rule.
max_body_length = 74

# Rule: No leading, trailing, or consecutive spaces.
whitespace = true

Set up automatic commit message validation:

git sumi --init commit-msg

Before each commit, git-sumi will lint your commit message. If it doesn't meet your project's rules, you'll see an error message and the commit will be aborted.
