pydepgraph is a stand-alone program that analyzes one or more tree of Python sources to find dependencies amongst the files, and output a DOT file, suitable to be displayed or converted to an image.
From the command line help.
usage: pydepgraph [-h] [-p PATH] [-e EXCLUDE] [-c CLUSTERS] [-r] [-g GRAPH]
[-C]
Draw the dependency graph of a Python project.
optional arguments:
-h, --help show this help message and exit
-p PATH, --path PATH comma separated list of paths to include
-e EXCLUDE, --exclude EXCLUDE
comma separated list of paths to exclude
-c CLUSTERS, --clusters CLUSTERS
comma separated list of clusters
-r, --no-recursive do not descend into subdirectories
-g GRAPH, --graph GRAPH
type of graph: 0 (without clusters), 1 (with
clusters), 2 (only clusters), 3 (only clusters,
drawing also self edges
-C, --concentrate merge common path of different edges
It is important to notice that the paths specified with the -p switch must be the root of the source tree, in order to let pydepgraph recognize correctly the dependencies. For example, if you want that the instruction
import tornado.ioloopis correctly assessed as an edge to tornado/ioloop.py, you need to specify the parent directory of tornado (i.e., the grandparent of ioloop.py) in the path list. In future versions this limitation could be removed to allow sub-project inspections.
