git-show
Showing a commit
$ git show d370f56
>>> repo = pygit2.Repository('/path/to/repository')
>>> commit = repo.revparse_single('d370f56')
Show log message
>>> message = commit.message
Show SHA hash
>>> hash = commit.hex
Show diff
>>> diff = repo.diff(commit.parents[0], commit)
Show all files in commit
>>> for e in commit.tree:
>>> print(e.name)
Produce something like a git show message
Then you can make your message:
>>> from datetime import datetime, timezone, timedelta
>>> tzinfo = timezone( timedelta(minutes=commit.author.offset) )
>>>
>>> dt = datetime.fromtimestamp(float(commit.author.time), tzinfo)
>>> timestr = dt.strftime('%c %z')
>>> msg = '\n'.join([f'commit {commit.tree_id.hex}',
... f'Author: {commit.author.name} <{commit.author.email}>',
... f'Date: {timestr}',
... '',
... commit.message])
