Project Abandoned #################

Many apologies. I've stopped maintaining this project due to personal time constraints.

https://github.com/Lewiscowles1986/py-call-graph is a currently maintained fork.

I'm happy to forward users to any new forks, or to discuss PyPI ownership.

Python Call Graph #################

Welcome! Python Call Graph is a Python <http://www.python.org>_ module that creates call graph <http://en.wikipedia.org/wiki/Call_graph>_ visualizations for Python applications.

Project Status

The latest version is 1.0.1 which was released on 2013-09-17, and is a backwards incompatible from the previous release.

The project lives on GitHub <https://github.com/gak/pycallgraph/#python-call-graph>, where you can report issues <https://github.com/gak/pycallgraph/issues>, contribute to the project by forking the project <https://help.github.com/articles/fork-a-repo> then creating a pull request <https://help.github.com/articles/using-pull-requests>, or just browse the source code <https://github.com/gak/pycallgraph/>_.

The documentation needs some work stiil. Feel free to contribute :)

Features

• Support for Python 2.7+ and Python 3.3+.
• Static visualizations of the call graph using various tools such as Graphviz and Gephi.
• Execute pycallgraph from the command line or import it in your code.
• Customisable colors. You can programatically set the colors based on number of calls, time taken, memory usage, etc.
• Modules can be visually grouped together.
• Easily extendable to create your own output formats.

Quick Start

Installation is easy as::

pip install pycallgraph

You can either use the command-line interface <https://pycallgraph.readthedocs.io/en/develop/guide/command_line_usage.html> for a quick visualization of your Python script, or the pycallgraph module <https://pycallgraph.readthedocs.io/en/develop/api/pycallgraph.html> for more fine-grained settings.

The following examples specify graphviz as the outputter, so it's required to be installed. They will generate a file called pycallgraph.png.

The command-line method of running pycallgraph is::

$ pycallgraph graphviz -- ./mypythonscript.py

A simple use of the API is::

from pycallgraph import PyCallGraph
from pycallgraph.output import GraphvizOutput

with PyCallGraph(output=GraphvizOutput()):
    code_to_profile()
