Diff Sniffer for Git

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 a PHAR package. All you need is download it and install as a pre-commit hook.

$ wget https://github.com/diff-sniffer/git/releases/download/0.1.0/pre-commit.phar
$ chmod +x pre-commit.phar
$ mv pre-commit.phar /path/to/repo/.git/hooks/pre-commit

Alternatively, you can install the hook globally for a user (see man githooks):

$ git config --global core.hooksPath '~/.git/hooks' # choose a path if you already haven't
$ chmod +x pre-commit.phar
$ mv pre-commit.phar ~/.git/hooks/pre-commit

You can also install Diff Sniffer manually:

$ git clone git@github.com:diff-sniffer/git.git
$ cd diff-sniffer-pre-commit
$ composer install
$ bin/pre-commit --version

Continuous integration mode

Diff Sniffer for Git can also run on a CI server and validate pull requests. For example, on Travis CI:

$ wget https://github.com/diff-sniffer/git/releases/download/0.1.0/git-phpcs.phar
$ php git-phpcs.phar origin/$TRAVIS_BRANCH...$TRAVIS_PULL_REQUEST_SHA

Configuration

By default, the PHAR distribution uses the PSR2 coding standard. The configuration may be overridden by creating configuration file file in the project root.
