Description:

pyfsa 0.4.1

PyFSA







A python CLI to render finite state graphs.
This application takes a CSV file with state information, and uses it to either produce the finite state graph, and verify that strings are valid given the state information, a start state, and a desired state. The string subcommand is also able to render the traversal graph of a string through the state machine.
Installation
You can install this project directly from github with pip, but it is also available in pypi. Install it like so:
python3 -m pip install pyfsa

GraphViz is required to run this, as graphviz is the rendering engine used to create the png files. You can find lots of information on how to do that here: https://graphviz.org/download/
On Ubuntu, you can find it in your package manager or install it directly using APT:
$ apt install graphviz

You might need to also install the graphviz development library to ensure the Python wrapper pygraphviz runs properly. You can find more information on installing pygraphviz on their website. On Ubuntu, you can install it with the following command:
$ apt install libgraphviz-dev
