Diff Sniffer Pre-Commit Hook

This tool allows you using PHP_CodeSniffer as a pre-commit hook. The main difference from existing solutions that this one validates only changed lines of code but not the whole source tree.

Installation

Diff Sniffer is already built as PHAR-package with a few predefined configurations. All you need is download it and install as a pre-commit hook.

$ wget https://www.dropbox.com/s/cukhmq8wrsge5zr/pre-commit-psr2.phar
$ chmod +x pre-commit-psr2.phar
$ mv pre-commit-psr2.phar /path/to/repo/.git/hooks/pre-commit

Additionally there are builds without predefined standard (PHP_CodeSniffer uses PEAD by default) and with SugarCRM coding standard.

You can also install and configure Diff Sniffer manually.

$ git clone git@github.com:morozov/diff-sniffer-pre-commit.git
$ composer update
$ ln -s /path/to/diff-sniffer-pre-commit/bin/pre-commit /path/to/repo/.git/hooks/

Configuration

The coding standard used by default may be defined in config.php (doesn't exist by default). Similarly to PHP_CodeSniffer, both embedded and custom standards may be used.

<?php

return array(
    '--standard=PSR-2',
);

or

<?php

return array(
    '--standard=/path/to/custom/standard',
);

If you want to reuse the same installation of Diff Sniffer with different standards, you can pass --standard as command line option. You should use shell script wrapper as pre-commit hook instead of symlink then.

#!/bin/bash

/path/to/diff-sniffer-pre-commit/bin/pre-commit --standard=PSR-2
