Git-NetworkX

Port of https://github.com/hoduche/git-graph to NetworkX

Install

PyPi

pip install git-networkx

Git

pip install git+https://github.com/CircArgs/git-networkx.git

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/directory')
#networkx Digraph representing all nodes of the git repo

#Commits
#notice the path does not have to be .git in case you have used a different name
Commits = GitNX('my/repo/path/located/in/.got', "c")
#networkx Digraph representing only commits of the git repo

#again, the results of GitNX is just a networkx.DiGraph and as such you can do anything you would on such an object
[n for n in All if isinstance(n, Commit)]

Suppose you had a log like the following:

    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

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")
