PHP-CS-Fixer

The PHP-CS-Fixer task will run codestyle checks.

Composer

composer require --dev friendsofphp/php-cs-fixer

Config

The task lives under the phpcsfixer namespace and has following configurable parameters:

# grumphp.yml
grumphp:
    tasks:
        phpcsfixer:
            allow_risky: ~
            cache_file: ~
            config: ~
            rules: []
            using_cache: ~
            config_contains_finder: true
            verbose: true
            diff: false
            triggered_by: ['php']

allow_risky

Default: null

The allow_risky option allows you to set whether risky rules may run. Risky rule is a rule, which could change code behaviour. If not set, the default value is taken from config file (if it exists). By default, no risky rules are run.

cache_file

Default: null

You can change the location of the cache file by changing this property. When no cache_file is set, the default file .php-cs-fixer.cache will be used.

config

Default: null

By default, the .php-cs-fixer.php (local) or .php-cs-fixer.dist.php (to be distributed) will be used. You can specify an alternate location for this file by changing this option.

rules

Default: []

Rules may be specified as either a list or map. A list of rules may only turn certain rules on or off whereas a map may also configure rules where applicable.

In the following list-style example, PSR-2 rules are enabled but the line_ending rule is removed from the set, while the array_syntax rule is added.

rules:
    - '@[@PSR2](https://github.com/PSR2)'
    - -line_ending
    - array_syntax

The following map-style example is the same as the previous, except we take advantage of rule configuration to change the array_syntax validation mode to short array syntax ([]) instead of the default long syntax (array()).

rules:
    '[@PSR2](https://github.com/PSR2)': true
    line_ending: false
    array_syntax:
        syntax: short

Note that rule sets, beginning with the at symbol (@), must be escaped by being quoted and doubled due to limitations of the parser. However, when appearing in the key position as in the previous example, doubling is incorrect.

using_cache

Default: null

By using using_cache option you can set if the caching mechanism should be used. If not set, the default value is taken from config file (if it exists). The caching mechanism is enabled by default. This will speed up further runs by fixing only files that were modified since the last run. The tool will fix all files if the tool version has changed or the list of fixers has changed. Cache is supported only for tool downloaded as phar file or installed via composer.

config_contains_finder

Default: true

Intersection mode can only be used when you have a configuration file which contains a Finder. This mode works best since only files that are being commit and are in your configuration will be checked. When there is no Finder in your configuration, you'll have set this parameter to false. Otherwise, php-cs-fixer will crash the execution.

Note that activating this option with a consequent target directory will be slow on certain envs such as osx+docker.

verbose

Default: true

Show applied fixers.

diff

Default: false

Show the full diff that will be applied.

triggered_by

Default: [php]

This option will specify which file extensions will trigger the phpcsfixer task.
