Julia wrapper for the Spot LTL and automata manipulation library

Spot

This package provides Julia bindings to the Spot library for LTL and automata manipulation. It relies on CxxWrap.jl to interface julia with the Spot c++ library. You can find the c++ code with the wrapped functions in spot_julia, and the build script for the jll file in Yggdrasil.

Installation

using Pkg; Pkg.add("Spot.jl")

For the rendering, Spot requires GraphViz and dot2tex to be installed.

Usage

LTL Manipulation

Construct LTL formula using a non standard string literal:

f = ltl"FG a -> FG b"

The formula will be automatically parsed by Spot.

LTL to Automata Translation

using Spot

ltl = "FG A"
translator = LTLTranslator(deterministic=true)

a = translate(translator, ltl)

Tutorial

A basic tutorial is available in docs/spot_basic_tutorial.ipynb

Notes

Right now, the wrapping of all the c++ functions present in libspot is not automatic. Every function can be called using the Cxx interface. If you need to wrap a function that has not been wrapped yet, feel free to submit a Pull Request.
