[ bsd3, language, library, program ] [ Propose Tags ]

This package is a Haskell wrapper to the SMTLIB-based Horn-Clause/Logical Implication constraint solver used for Liquid Types.

The solver itself is written in Ocaml.

The package includes:

  1. Types for Expressions, Predicates, Constraints, Solutions

  2. Code for serializing the above

  3. Code for parsing the results from the fixpoint.native binary

  4. The Ocaml fixpoint code

  5. (Deprecated) Z3 binaries if you want to link against the API.
