Converts ASCII text to a graph (represented as a dictionary of connections andangles). It can represent directed and undirected graphs.

$ pip install ascii2graph

fromascii2graphimportgraphtext=r'''a->boo^   |   x|   v  /c<--d-e    | |    f-g'''result=graph(text)print(result)

This produces the following graph (dictionary):

result= {(1,4,'a'): [(1,7,'boo',90)],          (4,4,'c'): [(1,4,'a',0)],          (4,8,'d'): [(4,4,'c',270), (4,10,'e',90), (6,8,'f',180)],          (4,10,'e'): [(2,12,'x',45), (4,8,'d',270), (6,10,'g',180)],          (2,12,'x'): [(4,10,'e',225)],          (6,8,'f'): [(6,10,'g',90), (4,8,'d',0)],          (6,10,'g'): [(6,8,'f',270), (4,10,'e',0)],          (1,7,'boo'): [(4,8,'d',180)]}

Nodes can be anything that is not one of these characters:

- | / \ v ^ < >

There is one exception (sorry!): If "/" is part of[sometext/foo], then it is not interpretedas an edge. The reason is that I needed this to visualize Git branches and Git history where I needed[origin/somebranch].

I use it inhttps://github.com/bast/gitink to create SVG graphics for teachingGit DAGs from plain text files because it is so easy to change a text file andsimply generate a new SVG image. This module helps me to obtain a graphrepresentation that I can use somewhere else to generate graphics.
