G2 Haskell Symbolic Execution Engine

About

G2 performs lazy symbolic execution of Haskell programs to detect state reachability. It is capable of generating assertion failure counterexamples and solving for higher-order functions.

Dependencies

Setup:

  1. Install GHC 8.2.2 (other GHC 8 versions might also work)
  2. Install Z3
  3. Either:

a) Pull the Custom Haskell Standard Library into ~/.g2 by running bash base_setup.sh

b) Manually pull the base library. Add a file to the G2 folder, called g2.cfg that contains: base = /path/to/custom/library

Command line:

Reachability:

cabal run G2 ./tests/Samples/Peano.hs add

LiquidHaskell:

cabal run G2 -- --liquid ./tests/Liquid/Peano.hs --liquid-func add

Arguments:
