Code that graphs code

Project description

Code that graphs code

Uses the python AST to parse Python source code and build a call graph.


An example of the current output of the parser parsing itself.


pip install codegrapher

To generate graphs, graphviz must be installed.


At the command line

To parse a file and output results to the console:

codegrapher path/to/ --printed

To parse a file and output results to a file:

codegrapher path/to/ --output output_file_name --output-type png

To analyze a directory of files, along with all files it contains:

codegrapher -r path/to/directory --output multiple_file_analysis

And if you have a list of functions that aren’t useful in your graph, add it to a .cg_ignore file:

# cg_ignore file
# all lines beginning with '#' are ignored

# every function calls this, so it's not helpful in my graph:

# I don't want to see this in my graph:

Then add the –ignore flag to your command. Using the flag –remove-builtins provides the same functionality for ignoring items found in __builtins__.

As a Python module

To easily parse code in Python :

from codegrapher.parser import FileObject

file_object = FileObject('path/to/')

And then to add that code to a graph and render it (using graphviz):

from codegrapher.graph import FunctionGrapher

graph = FunctionGrapher()
graph.add_file_to_graph(file_object) = 'name.gv'
graph.format = 'png'

Which will produce your code as a png file, name.gv.png, along with a dot file name.gv

More documentation for the Python module can be found at Read the Docs.
