Using git from Python

from Luiz Fernando's post at http://blog.cpu.eti.br/?p=91 that the efforts to Pythonize libgit have stalled.

On #git, I was advised to simply call the git command suite. That's fine, and I can do it using the subprocess module in Python - but since I figured others may have done this also, does anyone know of a Python module that wraps some git commands? I'm thinking if others have gone down this path, they might have code that e.g. raises Exceptions when the git commands fail for some reason.

What have others on this list done lately for using git from Python?

That's what I'd do ...  (I wonder if it was me who so advised you :-)

As far as I can tell, there is exactly no downside to simply forking a
subprocess.  Why are you trying to avoid that?

If Popen doesn't already raise an exception when the child process fails, then it's surely a simple matter to check the exit code, and raise the exception yourself.

There have been many questions about this lately. For the impatient, grab git.py from the python-git directory of the ugit project:

I will work on making git.py a separate python-git project, upload it to pypi, and create a separate repo for it very soon.

The interface is blazingly simple. It is a 1:1 correspondance to the git command line interface. e.g. git.commit(F='/some/path.txt', s=True)

There are many examples in the t/ directory and within the ugit project itself. Let me know offline if you have any questions. The documentation could probably use some work.

That looks very friendly and object-oriented. It doesn't seem to have write support, based on a quick look - is that right? Is write support a feature you're considering adding?

Hi,

It is very fun, because I started my own project ten days ago with similar goals: making python bindings for git. Since I didn't have much imagination at that time, I called it "pygit", eventually renaming it later with a better name.

While being quite similar to git-python at first glance, its primary goal is to feel as pythonic as possible, and to be suitable for porcelainish scripts (in such, it is quite low-level wrt the operations it allows, and has repository writing at the top of its todo list)...

Despite it seems a bit older than gitpython if you look at the commit history, it seems less mature, probably because it's written mostly from scratch and not a raw port of the ruby bindings. For instance, docs are still missing, which is why I didn't announce it to this list yet. It seems it is roughly on par with git-python feature-wise, though.

I hope you'll like this one too ;-)

PS. Comments welcome.

Mmh. The LGPL one. I think I've copied the wrong file in and forgot to double-test ;-)
