Project Description

gr1py is an enumerative (or concrete) reactive synthesis tool for the GR(1) fragment of LTL. It is pure Python.

Installation

Releases are available from the Python Package Index at https://pypi.python.org/pypi/gr1py To get it from there and check the version, try

pip install gr1py
gr1py -V

pip should get dependencies for you if you do not have them. They are

If it is available, NetworkX (http://networkx.lanl.gov) will be used. However, it is not required. A simple built-in class for directed graphs will be used if NetworkX is not found.

If you want to hack on gr1py, clone the repository from https://github.com/slivingston/gr1py.git

Current CI server report:

Examples

Besides the Python package, a script named gr1py is installed that provides access to several routines from the command-line. Consider the file named examples/arbiter3.spc that is included in the source release. To check that the specification defined by it can be realized, try

gr1py -r examples/arbiter3.spc

To synthesize a winning strategy and dump it in the Graphviz DOT format, try

gr1py -t dot examples/arbiter3.spc > arbiter3-fsm.dot
dot -Tsvg -O arbiter3-fsm.dot

where the second command uses the program dot (part of Graphviz) to create an SVG file, likely named arbiter3-fsm.dot.svg; e.g., the file can be displayed using a Web browser or Inkscape.

A summary of command-line usage can be obtained by grpy -h.

Input formats

The default input format is that of gr1c (http://scottman.net/2012/gr1c).

Output formats

These are selected from the command-line using the -t switch. Each corresponds to a function in gr1py.output.
