Demo

from networkx.drawing.nx_pydot import write_dot
from git_networkx import GitNX, Commit
#everything
All = GitNX('my/repo/path/that/has/a/.git')
#networkx Digraph representing all nodes of the git repo

#Commits
Commits = GitNX('my/repo/path/that/has/a/.git', "c")
write_dot(Commits, "mycommits.dot")
#networkx Digraph representing only commits of the git repo

#which is equivalent to the subgraph obtained by (not in terms of ops)
[n for n in All if isinstance(n, Commit)]

Suppose you had a log like the following:

commit 80798c310455976e08fedd9b367794692ebb54a6
Author: CircArgs <quebecname@gmail.com>

    add file2 with text

commit 8c7f9cea1f6323d793cd035e2178636d6ebf0a36
Author: CircArgs <quebecname@gmail.com>

    add file 1

then

G=GitNX(".", "lch")

print(list(G.neighbors(Commit("80798c310455976e08fedd9b367794692ebb54a6"))))
# [Commit('8c7f9cea1f6323d793cd035e2178636d6ebf0a36')]

print(list(G.predecessors(Commit("80798c310455976e08fedd9b367794692ebb54a6"))))
# [Commit('9a99a4d85cb14005ca829e2cab8f626b4034b981')]

print(list(G.predecessors(Commit('9a99a4d85cb14005ca829e2cab8f626b4034b981'))))
# [LocalBranch('dev'), LocalBranch('master')]

Nodes

This table shows what nodes can be in a graph. The Letters denote the filters for creation of the graph as the second positional argument to git_networkx.GitNX i.e. the nodes argument.

As shown in above examples, the DiGraph from GitNX can be filtered by checking isinstance against the Node Classes below or by filtering by a an instance of one of the classes.

Overall Node Class: GitNode

Node kind	Letter	Node Class	Node kind	Letter	Node Class
blob	b	Blob	remote branch	r	RemoteBranch
tree	t	Tree	remote head	d	RemoteHead
commit	c	Commit	remote server	s	RemoteServer
local branch	l	LocalBranch	annotated tag	a	AnnotatedTag
local head	h	LocalHead	tag	g	Tag

By default all nodes are added to the DiGraph.

# you can get your commits, branches and the head of your local repo simply with lch
G=GitNX('../git_networkx_test/', "lch")
