fstflowchat

fstflowchat is a small, pedagogical, fst-based dialog toolkit.

fstflowchat uses finite state transducers to control dialog flow. It uses graphviz to visualize the dialog flow and as a graph specification language for the dialog FST. Each graph edge specifies two functions, a test function that determines if the edge is a valid transition, and an output fuction that determines the system's output as it changes state.

Installation

To install the development version, run

pip install git+https://github.com/abecode/fstflowchat

Currently the development version is preferred.

To run the stable version (in the future), run

pip install fstflowchat

Currently the only dependency is the graphviz application and the pygraphviz library. For mac installation issues, please use the following command as described in this stackoverflow question

python -m pip install \
    --global-option=build_ext \
    --global-option="-I$(brew --prefix graphviz)/include/" \
    --global-option="-L$(brew --prefix graphviz)/lib/" \
