PHP Coding Standards Fixer
==========================
The PHP Coding Standards Fixer (PHP CS Fixer) tool fixes your code to follow standards;
whether you want to follow PHP coding standards as defined in the PSR-1, PSR-2, etc.,
or other community driven ones like the Symfony one.
You can **also** define your (teams) style through configuration.
It can modernize your code (like converting the ``pow`` function to the ``**`` operator on PHP 5.6)
and (micro) optimize it.
If you are already using a linter to identify coding standards problems in your
code, you know that fixing them by hand is tedious, especially on large
projects. This tool does not only detect them, but also fixes them for you.
The PHP CS Fixer is maintained on GitHub at https://github.com/FriendsOfPHP/PHP-CS-Fixer
bug reports and ideas about new features are welcome there.
You can talk to us at https://gitter.im/PHP-CS-Fixer/Lobby about the project,
configuration, possible improvements, ideas and questions, please visit us!
Requirements
------------
PHP needs to be a minimum version of PHP 5.6.0.
Installation
------------
Locally
~~~~~~~
Download the `php-cs-fixer.phar`_ file and store it somewhere on your computer.
Globally (manual)
~~~~~~~~~~~~~~~~~
You can run these commands to easily access latest ``php-cs-fixer`` from anywhere on
your system:
.. code-block:: bash
$ wget http://cs.sensiolabs.org/download/php-cs-fixer-v2.phar -O php-cs-fixer
or with specified version:
.. code-block:: bash
$ wget https://github.com/FriendsOfPHP/PHP-CS-Fixer/releases/download/v2.10.2/php-cs-fixer.phar -O php-cs-fixer
or with curl:
.. code-block:: bash
$ curl -L http://cs.sensiolabs.org/download/php-cs-fixer-v2.phar -o php-cs-fixer
then:
.. code-block:: bash
$ sudo chmod a+x php-cs-fixer
$ sudo mv php-cs-fixer /usr/local/bin/php-cs-fixer
Then, just run ``php-cs-fixer``.
Globally (Composer)
~~~~~~~~~~~~~~~~~~~
To install PHP CS Fixer, `install Composer <https://getcomposer.org/download/>`_ and issue the following command:
.. code-block:: bash
$ composer global require friendsofphp/php-cs-fixer
Then make sure you have the global Composer binaries directory in your ``PATH``. This directory is platform-dependent, see `Composer documentation <https://getcomposer.org/doc/03-cli.md#composer-home>`_ for details. Example for some Unix systems:
.. code-block:: bash
$ export PATH="$PATH:$HOME/.composer/vendor/bin"
Globally (homebrew)
~~~~~~~~~~~~~~~~~~~
PHP-CS-Fixer is part of the homebrew-php project. Follow the installation
instructions at https://github.com/homebrew/homebrew-php if you don't
already have it.
.. code-block:: bash
$ brew install homebrew/php/php-cs-fixer
Update
------
Locally
~~~~~~~
The ``self-update`` command tries to update ``php-cs-fixer`` itself:
.. code-block:: bash
$ php php-cs-fixer.phar self-update
Globally (manual)
~~~~~~~~~~~~~~~~~
You can update ``php-cs-fixer`` through this command:
.. code-block:: bash
$ sudo php-cs-fixer self-update
Globally (Composer)
~~~~~~~~~~~~~~~~~~~
You can update ``php-cs-fixer`` through this command:
.. code-block:: bash
$ ./composer.phar global update friendsofphp/php-cs-fixer
Globally (homebrew)
~~~~~~~~~~~~~~~~~~~
You can update ``php-cs-fixer`` through this command:
.. code-block:: bash
$ brew upgrade php-cs-fixer
Usage
-----
The ``fix`` command tries to fix as much coding standards
problems as possible on a given file or files in a given directory and its subdirectories:
.. code-block:: bash
$ php php-cs-fixer.phar fix /path/to/dir
$ php php-cs-fixer.phar fix /path/to/file
By default ``--path-mode`` is set to ``override``, which means, that if you specify the path to a file or a directory via
command arguments, then the paths provided to a ``Finder`` in config file will be ignored. You can use ``--path-mode=intersection``
to merge paths from the config file and from the argument:
.. code-block:: bash
$ php php-cs-fixer.phar fix --path-mode=intersection /path/to/dir
The ``--format`` option for the output format. Supported formats are ``txt`` (default one), ``json``, ``xml``, ``checkstyle`` and ``junit``.
NOTE: the output for the following formats are generated in accordance with XML schemas
* ``junit`` follows the `JUnit xml schema from Jenkins </doc/junit-10.xsd>`_
* ``checkstyle`` follows the common `"checkstyle" xml schema </doc/checkstyle.xsd>`_
The ``--verbose`` option will show the applied rules. When using the ``txt`` format it will also displays progress notifications.
The ``--rules`` option limits the rules to apply on the
project:
.. code-block:: bash
$ php php-cs-fixer.phar fix /path/to/project --rules=@PSR2
By default the PSR1 and PSR2 rules are used.
The ``--rules`` option lets you choose the exact rules to
apply (the rule names must be separated by a comma):
.. code-block:: bash
$ php php-cs-fixer.phar fix /path/to/dir --rules=line_ending,full_opening_tag,indentation_type
You can also blacklist the rules you don't want by placing a dash in front of the rule name, if this is more convenient,
using ``-name_of_fixer``:
.. code-block:: bash
$ php php-cs-fixer.phar fix /path/to/dir --rules=-full_opening_tag,-indentation_type
When using combinations of exact and blacklist rules, applying exact rules along with above blacklisted results:
.. code-block:: bash
$ php php-cs-fixer.phar fix /path/to/project --rules=@Symfony,-@PSR1,-blank_line_before_statement,strict_comparison
Complete configuration for rules can be supplied using a ``json`` formatted string.
.. code-block:: bash
$ php php-cs-fixer.phar fix /path/to/project --rules='{"concat_space": {"spacing": "none"}}'
The ``--dry-run`` flag will run the fixer without making changes to your files.
The ``--diff`` flag can be used to let the fixer output all the changes it makes.
The ``--diff-format`` option allows to specify in which format the fixer should output the changes it makes:
* ``null``: no diff;
* ``udiff``: unified diff format.
The ``--allow-risky`` option (pass ``yes`` or ``no``) allows you to set whether risky rules may run. Default value is taken from config file.
Risky rule is a rule, which could change code behaviour. By default no risky rules are run.
The ``--stop-on-violation`` flag stops the execution upon first file that needs to be fixed.
The ``--show-progress`` option allows you to choose the way process progress is rendered:
* ``none``: disables progress output;
* ``dots``: multiline progress output with number of files and percentage on each line.
If the option is not provided, it defaults to ``dots`` unless a config file that disables output is used, in which case it defaults to ``none``. This option has no effect if the verbosity of the command is less than ``verbose``.
.. code-block:: bash
$ php php-cs-fixer.phar fix --verbose --show-progress=dots
The command can also read from standard input, in which case it won't
automatically fix anything:
.. code-block:: bash
$ cat foo.php | php php-cs-fixer.phar fix --diff -
Finally, if you don't need BC kept on CLI level, you might use `PHP_CS_FIXER_FUTURE_MODE` to start using options that
would be default in next MAJOR release (unified differ, dots, full-width progress indicator):
.. code-block:: bash
$ PHP_CS_FIXER_FUTURE_MODE=1 php php-cs-fixer.phar fix -v --diff

The ``--dry-run`` option displays the files that need to be
fixed but without actually modifying them:
.. code-block:: bash
$ php php-cs-fixer.phar fix /path/to/code --dry-run
Config file
-----------
Instead of using command line options to customize the rule, you can save the
project configuration in a ``.php_cs.dist`` file in the root directory of your project.
The file must return an instance of `PhpCsFixer\\ConfigInterface <https://github.com/FriendsOfPHP/PHP-CS-Fixer/blob/v2.10.2/src/ConfigInterface.php>`_
which lets you configure the rules, the files and directories that
need to be analyzed. You may also create ``.php_cs`` file, which is
the local configuration that will be used instead of the project configuration. It
is a good practice to add that file into your ``.gitignore`` file.
With the ``--config`` option you can specify the path to the
``.php_cs`` file.
The example below will add two rules to the default list of PSR2 set rules:
.. code-block:: php
<?php
$finder = PhpCsFixer\Finder::create()
->exclude('somedir')
->notPath('src/Symfony/Component/Translation/Tests/fixtures/resources.php')
->in(__DIR__)
;
return PhpCsFixer\Config::create()
->setRules([
'@PSR2' => true,
'strict_param' => true,
'array_syntax' => ['syntax' => 'short'],
])
->setFinder($finder)
;
**NOTE**: ``exclude`` will work only for directories, so if you need to exclude file, try ``notPath``.
See `Symfony\\Finder <https://symfony.com/doc/current/components/finder.html>`_
online documentation for other `Finder` methods.
You may also use a blacklist for the rules instead of the above shown whitelist approach.
The following example shows how to use all ``Symfony`` rules but the ``full_opening_tag`` rule.
.. code-block:: php
<?php
$finder = PhpCsFixer\Finder::create()
->exclude('somedir')
->in(__DIR__)
;
return PhpCsFixer\Config::create()
->setRules([
'@Symfony' => true,
'full_opening_tag' => false,
])
->setFinder($finder)
;
You may want to use non-linux whitespaces in your project. Then you need to
configure them in your config file.
.. code-block:: php
<?php
return PhpCsFixer\Config::create()
->setIndent("\t")
->setLineEnding("\r\n")
;
By using ``--using-cache`` option with ``yes`` or ``no`` you can set if the caching
mechanism should be used.
Caching
-------
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 rules has changed.
Cache is supported only for tool downloaded as phar file or installed via
composer.
Cache can be disabled via ``--using-cache`` option or config file:
.. code-block:: php
<?php
return PhpCsFixer\Config::create()
->setUsingCache(false)
;
Cache file can be specified via ``--cache-file`` option or config file:
.. code-block:: php
<?php
return PhpCsFixer\Config::create()
->setCacheFile(__DIR__.'/.php_cs.cache')
;
Using PHP CS Fixer on CI
------------------------
Require ``friendsofphp/php-cs-fixer`` as a ``dev`` dependency:
.. code-block:: bash
$ ./composer.phar require --dev friendsofphp/php-cs-fixer
Then, add the following command to your CI:
.. code-block:: bash
$ CHANGED_FILES=$(git diff --name-only --diff-filter=ACMRTUXB "${COMMIT_RANGE}")
$ if ! echo "${CHANGED_FILES}" | grep -qE "^(\\.php_cs(\\.dist)?|composer\\.lock)$"; then IFS=$'\n' EXTRA_ARGS=('--path-mode=intersection' '--' ${CHANGED_FILES[@]}); fi
$ vendor/bin/php-cs-fixer fix --config=.php_cs.dist -v --dry-run --stop-on-violation --using-cache=no "${EXTRA_ARGS[@]}"
Where ``$COMMIT_RANGE`` is your range of commits, eg ``$TRAVIS_COMMIT_RANGE`` or ``HEAD~..HEAD``.
Exit codes
----------
Exit code is built using following bit flags:
* 0 OK.
* 1 General error (or PHP minimal requirement not matched).
* 4 Some files have invalid syntax (only in dry-run mode).
* 8 Some files need fixing (only in dry-run mode).
* 16 Configuration error of the application.
* 32 Configuration error of a Fixer.
* 64 Exception raised within the application.
(applies to exit codes of the `fix` command only)
Helpers
-------
Dedicated plugins exist for:
* `Atom`_
* `NetBeans`_
* `PhpStorm`_
* `Sublime Text`_
* `Vim`_
Contribute
----------
The tool comes with quite a few built-in fixers, but everyone is more than
welcome to `contribute`_ more of them.
Fixers
~~~~~~
A *fixer* is a class that tries to fix one CS issue (a ``Fixer`` class must
implement ``FixerInterface``).
Configs
~~~~~~~
A *config* knows about the CS rules and the files and directories that must be
scanned by the tool when run in the directory of your project. It is useful for
projects that follow a well-known directory structures (like for Symfony
projects for instance).
