lib-arcanist-php-cs-extension

This library integrates PHP CS Fixer as lint engine to arcanist. It allows developer to automatically run php-cs-fixer on arc diff.

Before installing library

To automatically configure your .arcconfig add "Paysera\\Composer\\ArcConfigParser::parseArcConfig" script to post-install-cmd and post-update-cmd or other scipts - just make sure this script is executed on composer install.

Installation

• composer require --dev paysera/lib-arcanist-php-cs-extension.
• Make sure .php_cs file is in project directory.
• Make sure .arcconfig file contains following configurable default entries:
  • "lint.engine": "PhpCsFixerLintEngine"
  • "load": ["vendor/paysera/lib-arcanist-php-cs-extension/src/"]
  • "lint.php_cs_fixer.fix_paths" : ["src/"] - list of directories to run php-cs-fixer on.
  • "lint.php_cs_fixer.php_cs_binary" : "{your-bin-dir}/php-cs-fixer" - location for php-cs-fixer executable.
  • "lint.php_cs_fixer.php_cs_file": ".php_cs" - location for .php_cs file.

Example output

In case php-cs-fixer found no problems:

$ arc lint
 OKAY  No lint warnings.
