Git commit from python

I want to write a module in python (This is the learning project) to enhance my git experience. Is there a python module for various git commands? At least the basic ones (commit/diff/log/add)?

I saw GitPython but I couldn't find the support for (new) commits; i开发者_运维问答ts more of a repo browsing framework than a complete GIT interface. (Or did I miss something?)

Also, if there IS a python module for all this, will that be preferable, or executing the shell commands from python code?

In GitPython you create a commit from an index object.

In libgit2 you create a commit from a repository object.

You might also want to look at this question:

• Python Git Module experiences?

I think some python source could help beginners like me not to waste precious time on digging docs.

All commits will go to freshly created origin master

Here it is:

from git import Repo
import os

path = '/your/path/here'
if not os.path.exists(path):
    os.makedirs(path)

os.chdir(path)

repo = Repo.init(path).git

index = Repo.init(path).index

for x in xrange (1,10):
    fname = 'filename' + str(x)
    f.open(fname, 'wb+')
    f.write()
    f.close()
    repo.add(fname)

index.commit("initial commit")

Git is designed to consist of "plumbing" and "porcelain". Plumbing components form the foundation, low-level system: Managing objects, repositories, remotes, and so on. Porcelain, on the other hand, means more user-friendly high-level tools that use the plumbing.

Historically, only the most basic/performance-critical parts (mostly plumbing) were implemented in C, the rest used shell/perl scripts. To be more portable, more and more code was rewritten in C.

With this background, I would recommend to just use system calls to the git executable for your python wrapping. Consider your code as part of Git's porcelain. Compared to using a specialized library:

PRO

• No need to learn an API -- use the git commands you are familiar with
• Complete set of tools -- you can use porcelain and are not restricted to low-level functionality

CONTRA

• Need to parse command line output from git calls.
• Might be slower

This can be done with GitPython

Install it with:

pip install GitPython

And use it like this:

from git.repo import Repo

repo = Repo('/path/to/repository')

repo.index.add(['some_file'])
repo.index.commit('commit from python')

origin = repo.remotes[0]
origin.push()
