crufty

Because we all accumulate cruft over time.

A command-line tool to check for files that exceed specified line count thresholds in your codebase. Perfect for maintaining code quality and identifying potentially complex files that might need refactoring.

npm install -D crufty
# or
pnpm add -D crufty
# or
yarn add -D crufty

crufty ./**.{ts,js,jsx,astro} [options]

By default, crufty will check all files in the current directory against a threshold of 100 lines. You can specify file patterns or paths to check specific files.

# Check all files in current directory
crufty

# Check specific files or patterns
crufty src/**/*.ts src/**/*.js

# Set custom line threshold
crufty --threshold 200

# Warn instead of throwing error
crufty --warn

# Ignore specific patterns
crufty --ignore "*.test.ts,*.spec.js"

• -t, --threshold <number>: Line count threshold (default: 100)
• -w, --warn: Warn instead of throwing error (default: false)
• --no-gitignore: Disable gitignore patterns
• -s, --silent: Suppress all output except errors
• -i, --ignore <patterns>: Additional patterns to ignore (comma-separated)
• -v, --version: Output the version number
• -h, --help: Display help for command

You can use crufty as part of your pre-commit hooks to prevent committing files that exceed your line count threshold. Here's how to set it up:

1. Install the required dependencies:

npm install -D lint-staged husky
# or
pnpm add -D lint-staged husky
# or
yarn add -D lint-staged husky

2. Initialize husky:

npx husky

3. Add the following to your package.json:

{
  "scripts": {
    "prepare": "husky install"
  },
  "lint-staged": {
    "*.{js,jsx,ts,tsx,astro}": ["crufty"]
  }
}

4. Add the pre-commit hook:

npx husky add .husky/pre-commit "npx lint-staged"

Now crufty will run on all staged files before each commit, preventing commits that would introduce files exceeding your line count threshold.
