Commitplease

This node.js module validates git commit messages while you commit, according to the rules specified in the jQuery Commit Guidlines. These are pretty generic, so this module should be useful for most projects that care about commit message formats.

Installation

npm install commitplease

A git version of 1.8.5 or newer is recommended. If you use git commit --verbose, it is required.

Usage

Just commit as usual. This modules installs a git commit-msg hook, automatically validating all commit messages as you enter them. Invalid messages will be rejected, with details on what's wrong and a copy of the input.

API

The API is a work-in-progress

var validate = require('commitplease/lib/validate');
var errors = validate(commit.message);
if (errors.length) {
	postComment('This commit has ' + errors.length + ' problems!');
}

validate(message[, options]), returns Array

• message (String): The commit message to validate. Must use LF (\n) as line breaks.
• options (Object, optional): Use this to override the default settings, see properties and defaults below
• returns Array: Empty for valid messages, one or more items as String for each problem found

Options and their defaults:

component: true,
limits: {
	subject: 72,
	other: 80
}

Customizing the bundled options

The validation options can be overriden by configuring the commitplease property on your own project's package.json. This allows you to customize some of the validation rules available.

Here's an example for disabling the component message validation:

{
  "name": "Example",
  "description": "An example project with custom commit hook options",
  "devDependencies": {
    "commitplease": "1.10.x"
  },
  "commitplease": {
    "component": false
  }
}
