README

Custom PHP 8.0 ruleset for PHP_CodeSniffer.

Features

• 97% PSR12 compatible
• Slevomat rules
  • Slevomat coding-standard
  • Ruleset includes vast majority of Slevomat sniffs as they're great extension of PSR12 with wider scope and stricter requirements.
• Custom rules
  • Package also introduces its own sniffs with more additional checks.

Installation

Recommended way is to install using composer-bin plugin, so it won't interfere with your project's dependencies.

composer require --dev bamarni/composer-bin-plugin
composer bin phpcs require infinityloop-dev/coding-standard

Usage

Running phpcs out of the box:

// phpcs:
php vendor/bin/phpcs\
    --parallel=4\
    --standard=vendor-bin/phpcs/vendor/infinityloop-dev/coding-standard/InfinityloopCodingStandard/ruleset.xml\
    --extensions=php\
    app tests

// phpcbf:
php vendor/bin/phpcbf\
    --parallel=4\
    --standard=vendor-bin/phpcs/vendor/infinityloop-dev/coding-standard/InfinityloopCodingStandard/ruleset.xml\
    --extensions=php\
    app tests

Feel free to copy ruleset.xml in your project directory, customize configuration and create your own standard with this ruleset as its base.

Description

PHPCS sniffs - PSR12 ruleset

We use PHP_Codesniffers predefined PSR12 ruleset, but some slight modifications were made. Few sniffs are replaced with more generic/configurable ones and some are configured to achieve different result.

• declare(strict_types = 1); instead of PSR's declare(strict_types=1);
  • one space around = operator
• function abc($param) : ReturnType instead of PSR's function abc($param): ReturnType
  • one space before and after colon
• function($param) use ($use) instaed of PSR's function ($param) use ($use)
  • no space after function keyword
• use \Abc\Xyz\Class; instead of PSR's use Abc\Xyz\Class
  • Leading backslash in use
  • Although import names must already be fully qualified, we believe that using FQN is more logical here.

All other necessary sniffs to enforce remaining PSR12 rules are included.

Custom sniffs

InfinityloopCodingStandard.Classes.FinalClassVisibility 🔧

When class is final and doesn't extend any other class, it's safe to change visibility of all protected functions/properties to private.

InfinityloopCodingStandard.Namespaces.UseDoesStartWithBackslash 🔧

Inverted SlevomatCodingStandard.Namespaces.UseDoesNotStartWithBackslash sniff - require imports to start with backslash.

InfinityloopCodingStandard.ControlStructures.RequireMultiLineNullCoalesce 🔧

Enforces null coalesce operator to be reformatted to new line

InfinityloopCodingStandard.ControlStructures.SwitchCommentSpacing 🔧

Checks that there is a certain number of blank lines between code and comment

InfinityloopCodingStandard.TypeHints.UnionTypeHintFormat 🔧

Improved version of Slevomat UnionTypeHintFormat with added formatting of multiline unions

InfinityloopCodingStandard.Classes.ConstructorPropertyPromotionSpacing 🔧

Space constructor arguments one per line when Constructor Property Promotion is used

InfinityloopCodingStandard.Namespaces.ReferenceUsedNamesAfterUsage 🔧

Specialized version of Slevomat ReferenceUsedNamesOnlySniff with added rules when the sniff should reference by FQN or Use statement.

Sniff provides the following settings:

• count - Minimum number of occurrences after which the class will get imported via Use statement.
• length - The maximum length of the class up to which it will be used via FQN, if this length is exceeded it will be imported via Use statement.
• lineLength, lineClassLength - Class will get imported only if it's length is greater than lineClassLength and if the line length is greater than lineLength.

Slevomat sniffs

Detailed list of Slevomat sniffs with configured settings. Some sniffs are not included, either because we don't find them helpful, they are too strict, or collide with their counter-sniff (require/disallow pairs).
