LiquidHaskell is a static verifier for Haskell, based on Liquid Types

Code

You can get LiquidHaskell here See the README for installation instructions. LiquidHaskell is an active research project that is still rough around the edges. In particular error reporting is rather primitive. Constructive Feedback, or better yet, patches, additions and pull requests are extremely welcome.

Papers

To learn about the theory behind Liquid Types, I recommend reading first the PLDI 2008 paper and then the ESOP 2013 paper. Alternatively, one lazy weekend, you could curl up with:

• Pat Rondon's Ph.D Dissertation
• Tech Report
