pre-commit-taskid

A pre-commit hook that automatically appends task IDs from branch names to commit messages.

Overview

This pre-commit hook extracts task IDs from your branch names and automatically appends them to your commit messages. It's designed to work with branch naming conventions like:

• feature-1234
• bugfix-5678
• hotfix-9012
• user/feature-3456
• release/v1.0-7890

When you make a commit, the hook will extract the numeric ID (e.g., 1234) from your branch name and append it to your commit message in the format #1234.

Installation

Prerequisites

• Python 3.9 or higher
• pre-commit package installed

Using pip

pip install pre-commit-taskid

From Source

git clone https://github.com/0xsirsaif/pre-commit-taskid.git
cd pre-commit-taskid
pip install -e .

Usage

0. CLI - Not so useful

pre-commit-taskid <commit-msg-file>

1. Add to your pre-commit config

Add the hook to your .pre-commit-config.yaml file:

repos:
  - repo: https://github.com/0xsirsaif/pre-commit-taskid
    rev: v0.1.2 # Use the specific version tag
    hooks:
      - id: taskid-prepender
        stages: [prepare-commit-msg] # CRITICAL: This line is required!

2. Install the hook

# IMPORTANT: Must specify the prepare-commit-msg hook type
pre-commit install --hook-type prepare-commit-msg

3. Make commits as usual

The hook will automatically append the task ID to your commit messages.

Examples

Example 1: Feature Branch

# Create a feature branch
git checkout -b feature-1234

# Make changes and commit
git add .
git commit -m "Add login functionality"

# Resulting commit message:
# "Add login functionality (#1234)"

Example 2: Bugfix Branch

# Create a bugfix branch
git checkout -b bugfix-5678

# Make changes and commit
git add .
git commit -m "Fix null pointer exception"

# Resulting commit message:
# "Fix null pointer exception (#5678)"

Example 3: Branch with Path

# Create a branch with a path
git checkout -b user/feature-3456

# Make changes and commit
git add .
git commit -m "Add user profile"

# Resulting commit message:
# "Add user profile (#3456)"

Troubleshooting

Hook Not Running

If the hook isn't running:

1. Ensure you've installed it with the correct hook type:

   pre-commit install --hook-type prepare-commit-msg

2. Verify the hook is installed:

   ls -la .git/hooks/prepare-commit-msg

3. Check your .pre-commit-config.yaml includes stages: [prepare-commit-msg]

Task ID Not Extracted

If the task ID isn't being extracted:

1. Ensure your branch name follows the pattern with a hyphen followed by numbers at the end:

   • ✅ feature-1234
   • ✅ user/feature-1234
   • ❌ feature_1234
   • ❌ feature1234

2. Check the branch name:

   git branch --show-current

Parentheses Around Task ID

If you don't see parentheses around the task ID (e.g., #1234 instead of #(1234)):

1. Update to the latest version of the package

2. Clean the pre-commit cache:

   pre-commit clean

Advanced Configuration

Using with Local Hooks

You can also use the hook locally without specifying a repository:

repos:
  - repo: local
    hooks:
      - id: taskid-prepender
        name: Task ID Prepender
        entry: pre-commit-taskid
        language: python
        stages: [prepare-commit-msg]
        additional_dependencies: ["pre-commit-taskid==0.1.0"]

Manual Testing

To test the hook manually:

# Create a test commit message
echo "Test commit" > .git/COMMIT_EDITMSG

# Run the hook manually
pre-commit-taskid .git/COMMIT_EDITMSG

# Check the result
cat .git/COMMIT_EDITMSG

Development

Testing
