This library provides a pure haskell interface to many SMT solvers by implementing the SMTLib2 language. SMT solving is done by spawning a SMT solver process and communicating with it.

Features

  • Communication via the SMTLIB2-format with solvers who support it (Currently Z3, MathSAT and CVC4).
  • Native bindings for solvers without a (proper) SMTLIB2 interface (Currently stp, boolector and yices).
  • Supports haskell data types (automatic instance generation available via template-haskell).

Installation

To install this package, you need cabal-install. The first package to install must be “smtlib2”:

cabal install

After this, you can install the extra packages in whatever order you wish.

PackageLocation
smtlib2-thextras/th
smtlib2-stpbackends/stp
smtlib2-boolectorbackends/boolector
smtlib2-yicesbackends/yices

Supported solvers

For the moment, only Z3 supports every feature implemented in this interface. MathSAT implements most features, except for data types.
