## Install
```
$ npm install --save clinton
```
## Usage
```js
const clinton = require('clinton');
clinton.lint('/Users/sam/projects/clinton', {rules: {'license': ['error', 'MIT']}}).then(validations => {
console.log(validations);
/*
[
{
ruleId: 'license',
severity: 'error',
message: 'License is not of type MIT (http://www.opensource.org/licenses/MIT).'
}
]
*/
});
```
Instead of passing the rules as an option, you can also add them to your `package.json` file.
```json
{
"name": "foo",
"license": "ISC",
"clinton": {
"rules": {
"license": ["error", "MIT"]
}
}
}
```

## Plugins
Everyone can create plugins or custom rules that can be validated with `Clinton`. The name of the plugin should be
`clinton-plugin-*` where `*` is the name of the plugin.
### Example
Let's create a `clinton-plugin-file-exists` rule that checks if the file provided as argument really exists.
```js
'use strict';
module.exports = ctx => {
const fileName = ctx.options[0];
if (!ctx.files.includes(fileName)) {
ctx.report({
message: `File ${fileName} does not exist.`
});
}
};
```
You can also return a promise if you are performing asynchronous operations.
You can wrap this up in a project, publish it to [npm](https://www.npmjs.com/) and install it in every project where you want to check if a file in your project really exists.
```json
{
"name": "Unicorn",
"description": "My unicorn package",
"version": "1.0.0",
"scripts": {
"test": "clinton"
},
"devDependencies": {
"clinton": "*",
"clinton-plugin-file-exists": "1.0.0"
},
"clinton": {
"plugins": [
"file-exists"
],
"rules": {
"file-exists": ["error", "index.js"]
}
}
}
```
When running `npm test`, `clinton` will execute your plugin and will use `index.js` as the option argument. The first that is passed to the plugin, `error` in this example, indicates the severity of the error.
