Commit Message Hooks

The commit-msg hook validates commit messages before they are saved, ensuring consistent message format and quality.

Use Cases

• Enforce commit message format
• Check for required elements (issue numbers, etc.)
• Validate message length
• Ensure proper capitalization

Example Hook

#!/bin/bash
# .git/hooks/commit-msg

commit_regex='^(feat|fix|docs|style|refactor|test|chore)(\(.+\))?: .{1,50}'

if ! grep -qE "$commit_regex" "$1"; then
    echo "Invalid commit message format!"
    echo "Format: type(scope): description"
    exit 1
