Sniff

Simpler PHP code sniffer, built on top of PHP-CS-Fixer.

This project has been replaced by Pretty

Why?

PHP-CS-Fixer can validate and fix the formatting of your code.

Sniff is a command that wraps php-cs-fixer to make it easier to use and configure.

It boils down to a simple .sniff.json file and 3 commands:

$ sniff validate

Validates that your code complies with your coding standard. Useful in CI to run on each pull request or commit.

$ sniff diff

Validates that your code complies with your coding standard and outputs the diff necessary to fix the errors. Useful to review the fixes before applying them.

$ sniff fix

Fix your code to make it compliant with your coding standard.

Installation

composer require mnapoli/sniff

You can then invoke the command with:

$ vendor/bin/sniff

You can also install it globally with Composer to be able to call it with sniff:

• composer global require mnapoli/sniff
• add the ~/.composer/bin path to your PATH

Configuration

Sniff is configured using a .sniff.json file:

{
    "paths": [
        "src",
        "tests"
    ],
    "rules": {
        "@PSR2": true
    },
    "allow-risky": true
}

• paths (mandatory): list of directories or files to analyze
• rules (default: @PSR2): list of rules to enable (detailed below)
• allow-risky (default: no): allows you to set whether risky rules may run (a risky rule is a rule which could change the code's behaviour)

The complete list of rules is detailed in PHP-CS-Fixer's documentation.

Below is an example that enables PSR-2 + Symfony's coding standard, along with a few custom options:

{
    "paths": [ ... ],
    "rules": {
        "@PSR2": true,
        "@Symfony": true,
        "array_syntax": {
            "syntax": "short"
        },
        "blank_line_before_return": false
    }
}

Contributing

To run the tests:
