The missing checkstyle for twig!

Twigcs aims to be what phpcs is to php. It checks your codebase for violations on coding standards.

How to install


composer require --dev friendsoftwig/twigcs

to install friendsoftwig/twigcs with composer.


phive install friendsoftwig/twigcs

to install friendsoftwig/twigcs with phive.

How to run

Basically, just run:

twigcs /path/to/views

On Symfony projects, you can run, for instance:

twigcs /project/dir/app/Resources/views

You will get a summary of the violations in the console. The exit code of the command is based on the severity of any violation found. By default, twigcs only tolerates info, this can be changed at run time:

twigcs /path/to/views --severity error   # Allows info and warnings
twigcs /path/to/views --severity warning # Allows info
twigcs /path/to/views --severity info    # Disallows info
twigcs /path/to/views --severity ignore  # Allows everything

With the example above, info is still displayed but not altering the exit code.

You can also exclude relative subfolders of path like this:

twigcs /path/to/views --exclude vendor

Tips: You can use multiple exclude parameters.

Restricting output

By default TwigCS will output all lines that have violations regardless of whether they match the severity level specified or not. If you only want to see violations that are greater than or equal to the severity level you've specified you can use the --display option. For example.

twigcs /path/to/views --severity error --display blocking

Would only display errors and not warnings.

Alternatively you can use --display all which is the default behaviour as described above.

Continuous Integration

Twigcs can be used with your favorite CI server. The command itself will return a consistent exit code telling the CI job if it failed or succeeded. You can also have a nice xml report (checkstyle format):

twigcs /path/to/views --reporter checkstyle > /path/to/report.xml


Twigcs currently supports to following reporters:

twigcs /path/to/views --reporter console
twigcs /path/to/views --reporter checkstyle
twigcs /path/to/views --reporter junit
twigcs /path/to/views --reporter emacs
twigcs /path/to/views --reporter json
twigcs /path/to/views --reporter csv
twigcs /path/to/views --reporter githubAction
twigcs /path/to/views --reporter gitlab

Using older twig versions

By default twigcs is using Twig 3. This means that features like filter tags or filtered loops using if are not supported anymore. You can use an older twig version using the twig-version option:

twigcs /path/to/views --twig-version 2

Custom coding standard

At the moment the only available standard is the official one from twig.

You can create a class implementing RulesetInterface and supply it as a --ruleset option to the CLI script:

twigcs /path/to/views --ruleset \MyApp\TwigCsRuleset

Note: twigcs needs to be used via composer and the ruleset class must be reachable via composer's autoloader for this feature to work. Also note that depending on your shell, you might need to escape backslashes in the fully qualified class name:

twigcs /path/to/views --ruleset \\MyApp\\TwigCsRuleset

For more complex needs, have a look at the custom ruleset documentation.

File-based configuration

Using configuration, you can easily store per-project settings:

// ~/.twig_cs.dist.php


use FriendsOfTwig\Twigcs;

return Twigcs\Config\Config::create()
    ->setSpecificRuleSets([ // Every file matching the pattern will use a different ruleset.
        '*/template.html.twig' => Acme\Project\CustomRuleset::class,

This configuration will be applied if you call twigcs from the ~/ directory. If you run twigcs from outside this directory, you must use the --config option:

cd ~/dirA
twigcs --config ~/dirB/.twig_cs.dist.php # Will lint templates in ~/dirA with the config of ~/dirB

By default, the files

  • .twig_cs.php
  • .twig_cs
  • .twig_cs.dist.php
  • .twig_cs.dist

are looked up in your current working directory (CWD).

You can also provide finders inside config files, they will completely replace the path in the CLI:

// ~/.twig_cs.dist.php


use FriendsOfTwig\Twigcs;

$finderA = Twigcs\Finder\TemplateFinder::create()->in(__DIR__.'/dirA');
$finderB = Twigcs\Finder\TemplateFinder::create()->in(__DIR__.'/dirB');

return Twigcs\Config\Config::create()
    // ...

In this case, calling twigcs from the ~/ directory of the config will run the linter on the directories pointed by the finders. If you explicitly supply a path to the CLI, it will be added to the list of linted directories:

twigcs ~/dirC # This will lint ~/dirA, ~/dirB and ~/dirC using the configuration file of the current directory.

Template resolution

Using file based configuration, you can provide a way for twigcs to resolve template. This enables better unused variable/macro detection. Here's the simplest example when you have only one directory of templates.



use FriendsOfTwig\Twigcs;

return Twigcs\Config\Config::create()
    // ...
    ->setTemplateResolver(new Twigcs\TemplateResolver\FileResolver(__DIR__))

Here is a more complex example that uses a chain resolver and a namespaced resolver to handle vendor templates:



use FriendsOfTwig\Twigcs;

return Twigcs\Config\Config::create()
    ->setTemplateResolver(new Twigcs\TemplateResolver\ChainResolver([
        new Twigcs\TemplateResolver\FileResolver(__DIR__ . '/templates'),
        new Twigcs\TemplateResolver\NamespacedResolver([
            'acme' =>  new Twigcs\TemplateResolver\FileResolver(__DIR__ . '/vendor/Acme/AcmeLib/templates')

This handles twig namespaces of the form @acme/<templatepath>.
