This repository will give access to new rules for the ESLint tool. You should use it only if you are developing an AngularJS application.
Since the 0.0.4 release, some rules defined in [John Papa's Guideline](https://github.com/johnpapa/angular-styleguide/blob/master/a1) have been implemented. In the description below, you will have a link to the corresponding part of the guideline, in order to have more information.

- [Team](#team)## Usage with [shareable](http://eslint.org/docs/developer-guide/shareable-configs.html) config
1. Install `eslint` as a dev-dependency:
```shell
npm install --save-dev eslint
```2. Install `eslint-plugin-angular` as a dev-dependency:
```shell
npm install --save-dev eslint-plugin-angular
```3. Use the shareable config by adding it to your `.eslintrc`:
```yaml
extends: plugin:angular/johnpapa
```## Usage without shareable config
1. Install `eslint` as a dev-dependency:
```shell
npm install --save-dev eslint
```2. Install `eslint-plugin-angular` as a dev-dependency:
```shell
npm install --save-dev eslint-plugin-angular
```3. Enable the plugin by adding it to your `.eslintrc`:
```yaml
plugins:
- angular
```
4. You can also configure these rules in your `.eslintrc`. All rules defined in this plugin have to be prefixed by 'angular/'```yaml
plugins:
- angular
rules:
- angular/controller_name: 0
```----

## Need your help
It is an opensource project. Any help will be very useful. You can :
- Create issue
- Send Pull Request
- Write Documentation
- Add new Features
- Add new Rules
- Improve the quality
- Reply to issuesAll development happens on the `development` branch. This means all pull requests should be made to the `development` branch.
If it is time to release, @Gillespie59 will bump the version in `package.json`, create a Git tag and merge the `development` branch into `master`. @Gillespie59 will then publish the new release to the npm registry.
## How to create a new rule
We appreciate contributions and the following notes will help you before you open a Pull Request.
### Check the issues
Have a look at the existing issues. There may exist similar issues with useful information.
### Read the documentation
There are some useful references for creating new rules. Specificly useful are:
* [The Context Object](http://eslint.org/docs/developer-guide/working-with-rules#the-context-object) - This is the most basic understanding needed for adding or modifying a rule.
* [Options Schemas](http://eslint.org/docs/developer-guide/working-with-rules#options-schemas) - This is the preferred way for validating configuration options.
* [Scope](http://estools.github.io/escope/Scope.html) - This is the scope object returned by `context.getScope()`.### Files you have to create
* `rules/.js`
* JavaScript file with the new rule
* The filename `` is exactly the usage name in eslint configs `angular/`
* Have a look at the `angularRule` wrapper and the `utils` (both in `rules/utils/`) - they probably make things easier for you
* Add a documentation comment to generate a markdown documentation with the `gulp docs` task
* `test/.js`
* Write some tests and execute them with `gulp test`
* Have a look at the coverage reports `coverage/lcov-report/index.html`
* `examples/.js`
* Add some examples for the documentation
* Run the `gulp docs` task to test the examples and update the markdown documentation
* `docs/.md`
* Generated by the `gulp docs` task### Files you have to touch
* `index.js`
* Add your rule `rulesConfiguration.addRule('', [0, {someConfig: 'someValue'}])`### Before you open your PR
* Check that the `gulp` task is working
* Commit generated changes in `README.md` and `docs/.md`
* Open your PR to the `development` branch NOT `master`### Rules specific for Angular 1 or 2
We can use a property, defined in the ESLint configuration file, in order to know which version is used : Angular 1 or Angular 2. based on this property, you can create rules for each version.
```yaml
plugins:
- angularrules:
angular/controller-name:
- 2
- '/[A-Z].*Controller$/'globals:
angular: truesettings:
angular: 2
```And in your rule, you can access to this property thanks to the `context` object :
```javascript
//If Angular 2 is used, we disabled the rule
if(context.settings.angular === 2){
return {};
}return {
'CallExpression': function(node) {
}
};
```## Default ESLint configuration file
Here is the basic configuration for the rules defined in the ESLint plugin, in order to be compatible with the guideline provided by @johnpapa :
```yaml
rules:
no-use-before-define:
- 0
