Pre-commit Hooks

Setup

pip3 install pre-commit
pre-commit install --hook-type pre-commit --hook-type pre-push

Usage

# Run on staged files
pre-commit run

# Run on specific files
pre-commit run --files src/index/hnsw/hnsw.cc include/knowhere/index/index.h

# Run on all files
pre-commit run --all-files

Commit Workflow

# 1. Make changes
# 2. Run pre-commit on changed files
pre-commit run --files <changed-files>

# 3. Stage and commit
git add .
git commit -m "message"

Common Issues

Pre-commit hooks run automatically on commit. Fix any failures before pushing.
