Use GitPython to see what's going in git

Hi, it's NISHIO Hirokazu. I'm planning to make a git cheat sheet for beginners. I want to see what's going in git, and GitPython tells it to me! Now we can see the change of index, HEAD, branches, tags, objects and their contents. What's else?

# easy_install GitPython


>>> from git import *
>>> r = Repo(".")
>>> r.index.entries
{('README', 0): (100644, 432a4b6de3c8318e1e59178492608cc10e48b00a, 0, README)}


>>> for k in r.odb.sha_iter():
... r.odb.info(k)
('"b\xde\x0c\x12\x1f"\xdf\x8ex\xf5\xa3}n\x11O\xd3"\xc0\xb0', 'blob', 5)
('C*Km\xe3\xc81\x8e\x1eY\x17\x84\x92`\x8c\xc1\x0eH\xb0\n', 'blob', 10)
("I'T\x08\xd5T\xd5[\xaa\xd5\x99\xe5\xb4\x19\xed\x81\xecn\xbd0", 'commit', 190)
('\xd2\x12\x83\xc7\x04E\x08\xcf:J\xac\xce\xfd\x91x\xf6u\x9c#\xda', 'tree', 34)

>>> for k in r.odb.sha_iter():
... r.odb.stream(k).read()
'tree d21283c7044508cf3a4aaccefd9178f6759c23da\nauthor NISHIO Hirokazu 1303459640 +0900\ncommitter NISHIO Hirokazu 1303459640 +0900\n\nmsg\n'
'100644 README\x00"b\xde\x0c\x12\x1f"\xdf\x8ex\xf5\xa3}n\x11O\xd3"\xc0\xb0'

>>> r.branches # equals to r.heads?
[<git.Head "refs/heads/master">]
