Running

bin/regreph <testfile> <projectdir> <refspec>

An example test file is https://gist.github.com/lox/33ab5a91edfaf487acf9

The refspec refers to a particular git revision, for instance HEAD~10 or a SHA1 hash.

Installing

git clone git://github.com/lox/regreph.git
cd regreph
composer install

Requires XHProf from PECL. Suggest having a copy of the FB xhprof project running somewhere to use the web view for comparison:

git clone git://github.com/facebook/xhprof.git
phpup xhprof/xhprof_html/index.php
