## Install

```sh
npm install validate-commit --save-dev
```

## Features

Even though there are a couple of other packages that do this, this one has a few quality of life changes.

- **Lets you decide how to validate** the commit messages (see [here](#usage))
- It validate commit files coming from both strings and files
- Supports the following **presets**:
  + [angular](./conventions/angular.md)
  + [atom](./conventions/atom.md)
  + [eslint](./conventions/eslint.md)
  + [ember](./conventions/ember.md)
  + [jquery](./conventions/jquery.md)
  + [jshint](./conventions/jshint.md)
- Supports **ignore patterns**
- Uses [chalk][chalk-url] module to color messages
- Logging can be muted via **SILENT** environment variable

## Usage

### With git hooks

E.g., using [git-scripts][git-scripts-url].

```json
"git": {
    "scripts": {
        "commit-msg": "./node_modules/.bin/validate-commit-msg $1"
    }
}
```

### From CLI

```bash
$ validate-commit-msg 'chore(package): some message'
$ validate-commit-msg -p eslint 'New: Awesome feature'
$ validate-commit-msg -p ember '[DOC beta] Update CONTRIBUTING.md'
$ validate-commit-msg -p jshint '[[DOCS]] Awesome JS docs'
$ ...
```

When a wrong commit message is given it outputs an explaination.

```bash
$ validate-commit-msg 'unknown(something): wrong'
# 'unknown' is not an allowed type!
# Valid types are: feat, fix, docs, style, refactor, perf, test, chore, revert
```

However you can mute it:

```bash
$ validate-commit-msg -s 'unknown(something): wrong'
```

### Within node

```javascript
var validateCommit = require('validate-commit').validateMessage;
validateCommit('chore(package): some message'); // > true
validateCommit('New: Awesome', { preset: 'eslint' }); // > true
validateCommit('Unk: Awesome', { preset: 'eslint' }); // > false
// > The word "Unk" is not an allowed tag.
// > Valid types are: Fix, Update, Breaking, Docs, Build, New, Upgrade.
process.env.SILENT = true;
validateCommit('Unk: Awesome', { preset: 'eslint' }); // > false
```


## API

### JavaScript

```
