Add getChanges method

[derUli]

Unfortunately I wasn't able to get your tests running on my windoze machine.

But I verified my code with a standalone php script.

C:\Users\deruli\Documents\GitHub\git-php>php test.php
array(1) {
  ["src/GitRepository.php"]=>
  string(1) "M"
}

Thanks! Looks good. But I'm not sure about API, give me some time, I will think about it.

BTW. What is your use-case?

[derUli]

@janpecha I am the main developer of a content management system. I developed a git client extension module for it using your lib https://github.com/derUli/git_client

Ok, thanks.
