Using @simonw's LLM library to generate a git commit message based on the current git diff

gcllm.sh

# Generate the commit message using llm
current_branch=$(git rev-parse --abbrev-ref HEAD)
git_diff=$(git diff "$current_branch")

commit_message=$(echo "$git_diff" | llm prompt --model gpt-4o-mini "
    - Generate a conventional commit message based on the provided git diff.
    - Start with one of the following prefixes: 'build', 'chore', 'ci', 'docs', 'feat', 'fix', 'perf', 'refactor', 'revert', 'style', 'test'.
    - Summarize the changes at a high level without listing every code modification.
    - Use concise bullet points to describe key changes (up to 5 bullets).
    - Skip detailed descriptions for cosmetic changes by ruff.
    - **Do not include any Markdown formatting or code block delimiters (e.g., no triple backticks).**

    Format:
    {prefix}: {appropriate emoji} {summary}
     - {appropriate emoji} bullet one
     - {appropriate emoji} bullet two
     - {appropriate emoji} bullet three
     ...
")

# Strip any remaining triple backticks just in case
commit_message=$(echo "$commit_message" | sed '/^```$/d')

# Preview the generated message
echo "----------------------------------------"
echo "Generated commit message:"
printf "%s\n" "$commit_message"
echo "----------------------------------------"

# Prompt for confirmation
while true; do
    read -p "Do you want to use this commit message? (y/n) " confirm
    if [[ "$confirm" == "y" ]]; then
        git commit -m "$commit_message"
        echo "Commit made with the generated message."
        break
    elif [[ "$confirm" == "n" ]]; then
        echo "Commit aborted."
        break
    else
        echo "Invalid input. Please enter 'y' or 'n'."
    fi
done

This is nice man adding to my personal dotfiles!
