Introduction

Laravel Pint is an opinionated PHP code style fixer for minimalists. Pint is built on top of PHP-CS-Fixer and makes it simple to ensure that your code style stays clean and consistent.

Pint is automatically installed with all new Laravel applications so you may start using it immediately. By default, Pint does not require any configuration and will fix code style issues in your code by following the opinionated coding style of Laravel.

Installation

Pint is included in recent releases of the Laravel framework, so installation is typically unnecessary. However, for older applications, you may install Laravel Pint via Composer:

composer require laravel/pint --dev

Running Pint

You can instruct Pint to fix code style issues by invoking the pint binary that is available in your project's vendor/bin directory:

./vendor/bin/pint

You may also run Pint on specific files or directories:

./vendor/bin/pint app/Models
 
./vendor/bin/pint app/Models/User.php

Pint will display a thorough list of all of the files that it updates. You can view even more detail about Pint's changes by providing the -v option when invoking Pint:

./vendor/bin/pint -v

If you would like Pint to simply inspect your code for style errors without actually changing the files, you may use the --test option. Pint will return a non-zero exit code if any code style errors are found:

./vendor/bin/pint --test

If you would like Pint to only modify the files that have uncommitted changes according to Git, you may use the --dirty option:

./vendor/bin/pint --dirty

If you would like Pint to fix any files with code style errors but also exit with a non-zero exit code if any errors were fixed, you may use the --repair option:

./vendor/bin/pint --repair

Configuring Pint

As previously mentioned, Pint does not require any configuration. However, if you wish to customize the presets, rules, or inspected folders, you may do so by creating a pint.json file in your project's root directory:

{
    "preset": "laravel"
}

In addition, if you wish to use a pint.json from a specific directory, you may provide the --config option when invoking Pint:

./vendor/bin/pint --config vendor/my-company/coding-style/pint.json

Presets

Presets define a set of rules that can be used to fix code style issues in your code. By default, Pint uses the laravel preset, which fixes issues by following the opinionated coding style of Laravel. However, you may specify a different preset by providing the --preset option to Pint:

./vendor/bin/pint --preset psr12

If you wish, you may also set the preset in your project's pint.json file:

{
    "preset": "psr12"
}

Pint's currently supported presets are: laravel, per, psr12, symfony, and empty.

Rules

Rules are style guidelines that Pint will use to fix code style issues in your code. As mentioned above, presets are predefined groups of rules that should be perfect for most PHP projects, so you typically will not need to worry about the individual rules they contain.

However, if you wish, you may enable or disable specific rules in your pint.json file or use the empty preset and define the rules from scratch:

{
    "preset": "laravel",
    "rules": {
        "simplified_null_return": true,
        "array_indentation": false,
        "new_with_parentheses": {
            "anonymous_class": true,
            "named_class": true
        }
    }
}

Pint is built on top of PHP-CS-Fixer. Therefore, you may use any of its rules to fix code style issues in your project: PHP-CS-Fixer Configurator.

Excluding Files / Folders

By default, Pint will inspect all .php files in your project except those in the vendor directory. If you wish to exclude more folders, you may do so using the exclude configuration option:

{
    "exclude": [
        "my-specific/folder"
    ]
}

If you wish to exclude all files that contain a given name pattern, you may do so using the notName configuration option:

{
    "notName": [
        "*-my-file.php"
    ]
}

If you would like to exclude a file by providing an exact path to the file, you may do so using the notPath configuration option:

{
    "notPath": [
        "path/to/excluded-file.php"
    ]
}

Continuous Integration

GitHub Actions

To automate linting your project with Laravel Pint, you can configure GitHub Actions to run Pint whenever new code is pushed to GitHub. First, be sure to grant "Read and write permissions" to workflows within GitHub at Settings > Actions > General > Workflow permissions. Then, create a .github/workflows/lint.yml file with the following content:

name: Fix Code Style
 
on: [push]
 
jobs:
  lint:
    runs-on: ubuntu-latest
    strategy:
      fail-fast: true
      matrix:
        php: [8.3]
 
    steps:
      - name: Checkout code
        uses: actions/checkout@v4
 
      - name: Setup PHP
        uses: shivammathur/setup-php@v2
        with:
          php-version: ${{ matrix.php }}
          extensions: json, dom, curl, libxml, mbstring
          coverage: none
 
      - name: Install Pint
        run: composer global require laravel/pint
 
      - name: Run Pint
        run: pint
 
      - name: Commit linted files
        uses: stefanzweifel/git-auto-commit-action@v5
        with:
          commit_message: "Fixes coding style"
