print_check

A Git pre-commit hook that detects and prevents print/debug statements from being committed to your repository.

Features

• Automatically scans staged files for print/debug statements before commits
• Configurable file extensions and search patterns
• Optional warning mode vs blocking mode
• Interactive setup with saved configuration
• Preserves existing pre-commit hooks
• Shows line details for detected statements (optional)

Installation

npm install -g print_check

Or install as a dev dependency in your project:

npm install --save-dev print_check

Usage

Run the command in your git repository:

print_check

On first run, you'll be prompted to configure:

• File extensions to check (e.g., .js,.ts,.jsx,.tsx)
• Search patterns (e.g., console.log,console.error,debugger)
• Warning mode (allow commit with confirmation) or blocking mode (prevent commit)
• Whether to show line details for each detected statement

Your configuration will be saved to print_check_config.json in your project root.

Setup as Pre-commit Hook

To automatically run print_check before every commit, you can:

1. Just follow the setup by running print_check after downloading.

2. After completing the setup phase any terms found matching your search patterns will be flagged.

Configuration

Example print_check_config.json:

{
  "fileExtensions": [".js", ".ts", ".jsx", ".tsx"],
  "warnOnly": false,
  "searchTerms": ["console.log", "console.error", "debugger"],
  "hasLineDetails": true
}

• fileExtensions: Array of file extensions to check
• warnOnly: If true, prompts for confirmation; if false, blocks the commit
• searchTerms: Array of patterns to search for
• hasLineDetails: If true, shows line numbers and content for each match

Requirements

• Node.js >= 18.0.0
• Git repository
