Dependency Graph from Python imports

Carport

Dependency Graph from Python imports (CARPORT).

Installation

pip install carport

Usage

from carport.core import ImportGraph

depg = ImportGraph(root = '..', project='carport')
# vars(depg)

# specify irrelevant modules
ignore_nodes = ['io', 'IPython', 'pprint', 'subprocess']

# export to dot string
dot = depg.to_dot(ignore_nodes=ignore_nodes)
display(dot)

'digraph  {\n"carport.vis";\n"carport.core";\nnetworkx;\npathlib;\nast;\nkroki;\ngraphviz;\n"carport.vis" -> "carport.core"  [key=0];\nnetworkx -> "carport.core"  [key=0];\npathlib -> "carport.core"  [key=0];\nast -> "carport.core"  [key=0];\nkroki -> "carport.vis"  [key=0];\ngraphviz -> "carport.vis"  [key=0];\n}\n'

# draw graph with graphviz
dotg = depg.draw_dot(ignore_nodes=ignore_nodes)
display(dotg)

# export to d2 string
d2 = depg.to_d2(ignore_nodes=ignore_nodes)
display(d2)

# draw graph with d2 or kroki
d2g = depg.draw_d2(ignore_nodes=ignore_nodes, app='d2')
display(d2g)

# for large graphs, you can use gravis
#! pip install gravis

import networkx as nx 
import gravis as gv

g = depg.to_nx(ignore_nodes=ignore_nodes)
layout = nx.circular_layout(g, scale=4*len(g)**1.05)
for node_id, (x, y) in layout.items():
    node = g.nodes[node_id]
    node['x'], node['y'] = x, y
gv.d3(g, edge_curvature=1, node_hover_neighborhood = True, use_edge_size_normalization=True)

TODOs:

[] imports concerning __init__.py

[] py_d2 to d2 (like graphviz to graphviz)
