For example,

With range time:

g = git.Git("C:/path/to/your/repo") 
loginfo = g.log('--since=2013-09-01','--author=KIM BASINGER','--pretty=tformat:','--numstat')
print loginfo

Output:

3       2       path/in/your/solutions/some_file.cs

You can see the added lines, removed lines and the file with these changes.

You can get all the repository commits using:

import git
repo = git.Repo("/home/user/.emacs.d")
commits = list(repo.iter_commits("master", max_count=5))

Then you can identify yourself what kind of data gitpython offers:

dir(commits[0])

Some of them are:

• author
• committed_datetime
• hexsha
• message
• stats

Take an example:

>>> commits[0].author
<git.Actor "azzamsa <[email protected]>">

>>> commits[0].hexsha
'fe4326e94eca2e651bf0081bee02172fedaf0b90'

>>> commits[0].message
'Add ocaml mode\n'

>>> commits[0].committed_datetime
datetime.datetime(1970, 1, 1, 0, 0, 0, tzinfo=<git.objects.util.tzoffset object at 0x7fb4fcd01790>)

(committed_datetime outputs datetime object with locale object)

If you want to check if a commit contains a file (which is usable if you want to grab all commit from that file). You can use:

def is_exists(filename, sha):
    """Check if a file in current commit exist."""
    files = repo.git.show("--pretty=", "--name-only", sha)
    if filename in files:
        return True

Then to get all commit from a file:

def get_file_commits(filename):
    file_commits = []
    for commit in commits:
        if is_exists(filename, commit.hexsha):
            file_commits.append(commit)

    return file_commits

e.g I want to take all commits from 'init.el' file:

initel_file_commits = get_file_commits('init.el')

>>> initel_file_commits
[<git.Commit "fe4326e94eca2e651bf0081bee02172fedaf0b90">, <git.Commit
"e4f39891fb484a95ea76e8e07244b908e732e7b3">]

See that the function working correctly:

>>> initel_file_commits[0].stats.files
{'init.el': {'insertions': 1, 'deletions': 0, 'lines': 1}, 'modules/aza-ocaml.el': {'insertions': 28, 'deletions': 0, 'lines': 28}}

>>> initel_file_commits[1].stats.files
{'init.el': {'insertions': 1, 'deletions': 0, 'lines': 1}, 'modules/aza-calfw.el': {'insertions': 65, 'deletions': 0, 'lines': 65}, 'modules/aza-home.el': {'insertions': 0, 'deletions': 57, 'lines': 57}}

Hope it helps.

The GitPython Repo.iter_commits() function (docs) has support for ref-parse-style commit ranges. So you can do:

import git
repo = git.Repo("/path/to/your/repo")
commits = repo.iter_commits("d3513dbb9f5..598d268f")

Everything after that depends on the exact formatting you want to get. If you want something similar to git log --oneline, that would do the trick (it is a simplified form, the tag/branch names are not shown):

for commit in commits:
    print("%s %s" % (commit.hexsha, commit.message.splitlines()[0]))

GitPython uses the module logging. By adding logging.basicConfig(level=logging.DEBUG) before your code, it prints logs like

DEBUG:git.cmd:Popen(['git', 'fetch'], cwd=E:\path\foo, universal_newlines=False, shell=None)

If you want it to print formatted logs as you expect, you could modify GitPython's source code. I'm using Python 2.7 and my GitPython is installed at C:\Python27\lib\site-packages\git. You can run git.__file__ in REPL to find your installation directory. In the file C:\Python27\lib\site-packages\git\cmd.py, you can find a method def execute. It calls subprocess.Popen to run the command. You can modify the line log.debug before Popen or just insert print(' '.join(cmd)) at a proper line. If you are using Python 3.3 or newer, you could also refer to this answer on how to print the command with subprocess.
