# Coder

[![Build Status](https://travis-ci.org/pfrenssen/coder.svg?branch=8.x-3.x)](https://travis-ci.org/pfrenssen/coder)

Coder is a library for automated Drupal code reviews and coding standard fixes. It
defines rules for [PHP_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)

Built-in support for:
- "Drupal": Coding Standards https://www.drupal.org/coding-standards
- "DrupalPractice": Best practices for Drupal module development

Online documentation: https://www.drupal.org/node/1419980

Note that Javascript support has been removed. To check and fix Javascript files
please use [ESLint](http://eslint.org/) and see the
[Drupal ESLint](https://www.drupal.org/node/1955232) documentation.


## Installation

First, make sure Composer is installed correctly:

    which composer

If you get composer not found or similar, follow Composer's installation
instructions.

Install Coder (8.x-3.x) in your global Composer directory in your home directory
(`~/.composer`):

    composer global require drupal/coder

To make the `phpcs` and `phpcbf` commands available globally, add the Composer
bin path to your `$PATH` variable in `~/.profile`, `~/.bashrc` or `~/.zshrc`:

    export PATH="$PATH:$HOME/.composer/vendor/bin"

Register the Drupal and DrupalPractice Standard with PHPCS:

    phpcs --config-set installed_paths ~/.composer/vendor/drupal/coder/coder_sniffer


### Composer Installer Plugins

The Coder package (>= 8.2.11) now works with Composer Installer Plugins,
that find and register standards whenever packages are installed or updated.
To use such a plugin within your project, follow these steps.

    composer require --dev dealerdirect/phpcodesniffer-composer-installer
    composer require --dev drupal/coder

Now, you will see Drupal and DrupalPractice listed in the available PHP
CodeSniffer standards.

    vendor/bin/phpcs -i

The same can be done for a Composer global installation.

    composer global require dealerdirect/phpcodesniffer-composer-installer
    composer global require drupal/coder


## Usage

Check Drupal coding standards

    phpcs --standard=Drupal /file/to/drupal/example_module

Check Drupal best practices

    phpcs --standard=DrupalPractice /file/to/drupal/example_module

Automatically fix coding standards

    phpcbf --standard=Drupal /file/to/drupal/example_module


## Working with Editors

## Automated Testing (PHPUnit + PHPCS)

Coder Sniffer comes with a PHPUnit test suite to make sure the sniffs work correctly.
Use Composer to install the dependencies:

    composer install

Then execute the tests:

    ./vendor/bin/phpunit

Then execute the coding standards checker on Coder itself:

    ./vendor/bin/phpcs
