commit-message-append option

[MrXerios]

First of all, this is a great tool, my thanks for developing it.

I was wondering if it would be possible to add an option to add a modifier to the previous commit message rather than just put a new commit message.

For instance, the current behaviour is:
original commit: "added this and that"
auto-commit: "formatting"

but it could be:
original commit: "added this and that"
auto-commit: "added this and that (+formatting)"

This would make the latest commit messages less generic, which is usefull since these messages are directly visible.

Have a great day,
MrXerios

Thanks for the suggestion.

This is not something I would add to the core of git-auto-commit as this is something too specific. However, you can create this behaviour on your own by extracting the previous git commit message and append your message.

Here is an – untested – GitHub Actions workflow, that should help you in your projects.

name: Formatting

on:
  push
  pull_request

jobs:
  auto-format:
    runs-on: ubuntu-latest
    
    steps:
    - uses: actions/checkout@v4
      with:
        fetch-depth: 2  # Need at least 2 commits to get the previous one
        token: ${{ secrets.GITHUB_TOKEN }}
    
    - name: Setup Node.js
      uses: actions/setup-node@v4
      with:
        node-version: '18'
    
    - name: Install dependencies
      run: npm install
    
    - name: Run formatter
      run: npm run format
    
    - name: Extract previous commit message
      id: prev_commit
      run: |
        # Get the previous commit message (before the current HEAD)
        PREV_MSG=$(git log --format=%B -n 1 HEAD~1 | head -n 1)
        echo "message=$PREV_MSG" >> $GITHUB_OUTPUT
        echo "Previous commit message: $PREV_MSG"
    
    - name: Auto-commit changes
      uses: stefanzweifel/git-auto-commit-action@v5
      with:
        commit_message: "${{ steps.prev_commit.outputs.message }} (+formatting)"
