init-pre-commit

A CLI tool that automatically generates .pre-commit-config.yaml files based on detected project types.

Features

• Detects project languages (Python, Go, Rust) from file patterns
• Generates a pre-commit config with appropriate hooks for each language
• Includes common hooks by default (yaml check, trailing whitespace, gitleaks, etc.)
• Optionally installs pre-commit hooks automatically

Installation

cargo install --path .

Usage

# Initialize in current directory
init-pre-commit

# Initialize in a specific directory
init-pre-commit /path/to/repo

The tool will:

1. Verify the target is a git repository
2. Detect project types based on file patterns
3. Generate .pre-commit-config.yaml with appropriate hooks
4. Install pre-commit hooks (if pre-commit is available)

Default Hooks

All generated configs include:

• check-yaml - Validate YAML syntax
• end-of-file-fixer - Ensure files end with newline
• trailing-whitespace - Remove trailing whitespace
• check-merge-conflict - Detect merge conflict markers
• check-added-large-files - Prevent large files from being committed
• gitleaks - Scan for secrets

Language-Specific Hooks

Python

• black - Code formatter
• ruff - Fast linter with auto-fix

Go

• go-fmt - Format Go code
• go-vet - Report suspicious constructs
• go-imports - Manage imports

Rust

• fmt - Format Rust code
• clippy - Lint Rust code

Adding New Languages

Edit rules.yaml to add detection patterns and hooks for new languages:

- name: javascript
  detect_patterns:
    - "**/*.js"
    - "**/package.json"
  message: Detected JavaScript project
  hooks: |
    -   repo: https://github.com/pre-commit/mirrors-eslint
        rev: v8.56.0
        hooks:
        -   id: eslint
