Remote Void (v2.18.5) edition

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:

$ 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:

$ 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, junit and gitlab.

NOTE: the output for the following formats are generated in accordance with XML schemas

The --quiet Do not output any message.

The --verbose option will show the applied rules. When using the txt format it will also display progress notifications.

NOTE: if there is an error like “errors reported during linting after fixing”, you can use this to be even more verbose for debugging purpose

  • -v: verbose

  • -vv: very verbose

  • -vvv: debug

The --rules option limits the rules to apply to the project:

$ php php-cs-fixer.phar fix /path/to/project --rules=@PSR2

By default the PSR1 and PSR2 rules are used. If the --rules option is used rules from config files are ignored.

The --rules option lets you choose the exact rules to apply (the rule names must be separated by a comma):

$ php php-cs-fixer.phar fix /path/to/dir --rules=line_ending,full_opening_tag,indentation_type

You can also exclude 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:

$ php php-cs-fixer.phar fix /path/to/dir --rules=-full_opening_tag,-indentation_type

When using combinations of exact and exclude rules, applying exact rules along with above excluded results:

$ 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.

$ 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:

  • udiff: unified diff format;

  • sbd: Sebastianbergmann/diff format (default when using –diff without specifying 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. A rule is considered risky if it 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;

  • run-in: [deprecated] simple single-line progress output;

  • estimating: [deprecated] multiline progress output with number of files and percentage on each line. Note that with this option, the files list is evaluated before processing to get the total number of files and then kept in memory to avoid using the file iterator twice. This has an impact on memory usage so using this option is not recommended on very large projects;

  • estimating-max: [deprecated] same as dots;

  • dots: same as estimating but using all terminal columns instead of default 80.

If the option is not provided, it defaults to run-in 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.

$ php php-cs-fixer.phar fix --verbose --show-progress=estimating

The command can also read from standard input, in which case it won’t automatically fix anything:

$ 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, estimating, full-width progress indicator):

$ 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:

$ php php-cs-fixer.phar fix /path/to/code --dry-run

By using --using-cache option with yes or no you can set if the caching mechanism should be used.

Rule descriptions

Use the following command to quickly understand what a rule will do to your code:

$ php php-cs-fixer.phar describe align_multiline_comment

To visualize all the rules that belong to a ruleset:

$ php php-cs-fixer.phar describe @PSR2

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:

<?php

$config = new PhpCsFixer\Config();
return $config->setUsingCache(false);

Cache file can be specified via --cache-file option or config file:

<?php

$config = new PhpCsFixer\Config();
return $config->setCacheFile(__DIR__.'/.php_cs.cache');

Using PHP CS Fixer on CI

Require friendsofphp/php-cs-fixer as a dev dependency:

$ ./composer.phar require --dev friendsofphp/php-cs-fixer

Then, add the following command to your CI:

$ IFS='
$ '
$ CHANGED_FILES=$(git diff --name-only --diff-filter=ACMRTUXB "${COMMIT_RANGE}")
$ if ! echo "${CHANGED_FILES}" | grep -qE "^(\\.php_cs(\\.dist)?|composer\\.lock)$"; then EXTRA_ARGS=$(printf -- '--path-mode=intersection\n--\n%s' "${CHANGED_FILES}"); else EXTRA_ARGS=''; 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, e.g. $TRAVIS_COMMIT_RANGE or HEAD~..HEAD.

Environment options

The PHP_CS_FIXER_IGNORE_ENV environment variable can be used to ignore any environment requirements. This includes requirements like missing PHP extensions, unsupported PHP versions or by using HHVM.

NOTE: Execution may be unstable when used.

$ PHP_CS_FIXER_IGNORE_ENV=1 php php-cs-fixer.phar fix /path/to/dir

Exit code

Exit code of the fix command 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.
