Asciigraf is a python library that turns ascii diagrams of networks into network objects. It returns a networkx graph of nodes for each alpha-numeric element in the input text; nodes are connected in the graph to match the edges represented in the diagram by -, /, \ and |.

Installation

Asciigraf can be installed from pypi using pip:

~/$ pip install asciigraf

Usage

Asciigraf expects a string containg a 2-d ascii diagram. Nodes can be an alphanumeric string composed of words, sentences and punctuation (for a look at what is all tested to work, see the node recognition tests). Edges can be composed of -, /, \ and |.

import asciigraf

network = asciigraf.graph_from_ascii("""
          NodeA-----
                   |
                   |---NodeB
                                     """)

print(network)
>>> <networkx.classes.graph.Graph at 0x7f24c3a8b470>

print(network.edges())
>>> [('NodeA', 'NodeB')]

print(network.nodes())
>>> ['NodeA', 'NodeB']

Networkx provides tools to attach data to graphs, nodes and edges, and asciigraf leverages these in a number of ways; in the example below you can see that asciigraf uses this to attach a x, y position tuple to each node indicating the line/col position of each node ( 0,0 is at the top-left). It also attaches a length attribute to each edge which matches the number of characters in that edge, as well as a list of positions for each character an edge. In addition, the input data is attached as a graph attribute ascii_string for reference.

print(network.nodes(data=True))
>>> [('NodeA', {'position': (10, 1)}), ('NodeB', {'position': (23, 3)})]

print(network.edges(data=True))
>>> [('NodeA', 'NodeB', OrderedDict([('length', 10), 'points', [...]))]

print(network.edge['NodeA']['NodeB']['points'])
>>> [(15, 1), (16, 1), (17, 1), (18, 1),
     (19, 1), (19, 2), (19, 3), (20, 3), (21, 3), (22, 3)]

print(network.graph["ascii_string"])
>>>
    NodeA-----
             |
             |---NodeB

Asciigraf also lets you annotate the edges of graphs using in-line labels — denoted by parentheses. The contents of the label will be attached to the edge on which it is drawn with the attribute name label.

network = asciigraf.graph_from_ascii("""

    A---(nuts)----B----(string)---C
                  |
                  |
                  |
                  D---(pebbles)----E

""")

print(network.get_edge_data("A", "B")["label"])
>>> nuts

print(network.get_edge_data("B", "C")["label"])
>>> string

print(network.get_edge_data("D", "E")["label"])
>>> pebbles

print(hasattr(network.get_edge_data("B", "D"), "label"))
>>> False

Have fun!
