MiniStatix

A playground implementation of the Statix constraint language in Haskell.

This is meant to be a place to quickly prototype extensions and variations on the core Statix language.

It can execute a given ministatix specification on an aterm, or can be exercised in a REPL.

Build and Run

To build this project, you need to have the Haskell Toolstack (brew install haskell-stack on MacOS). Build the project using:

make

Enter the project's REPL using:

./statix repl

Check a file input.aterm against the specification src/spec.mstx using:

./statix check -I src spec input.aterm

The return code can be used to check the result of checking:

  • 0 for satisfied constraints
  • 64 for unsatisfied constraints
  • 65 for stuckness of the solver
  • 1 for other errors (spec doesn't parse, imported modules missing, etc)

Other makefile targets are:

  • setup to setup the build environment;
  • build to build the project;
  • test to run the test specifications in test/;
  • clean to remove the artifacts;
  • doc to build and show the generated documentation;
  • ghci to open a Haskell Interactive propt in the project directory;
  • install to install the binary in your user's local bin.

Editor support

There is barely any for this research language, but you can find an emacs syntax highlighting definition in tooling/.
