Demo of Liquid Haskell integration for Cabal and Stack.
This is a sample project set up with liquidhaskell-cabal. It includes:
- A .cabal file configured for
liquidhaskell-cabal, including custom LiquidHaskell flags for each component of the package. - A Setup.hs file file set up to hook
liquidhaskell-cabalinto the build process.
To use LiquidHaskell at all, you'll need to have the LiquidHaskell binary installed and available in your $PATH, via one of:
stack install liquidhaskell # if you're using Stack
cabal install liquidhaskell # if you're using Cabal directly
(Please make sure you have a version >= 0.6.0.0 installed.)
If you're using Cabal <1.24, you'll need to install the liquidhaskell-cabal package manually
before trying to build this project, to make it available to the Setup.hs file.
cabal install liquidhaskell-cabal-0.2.1.0
Stack and Cabal >=1.24 can automatically handle Setup.hs dependencies.
Once everything is set up, this sample project can be built with one of:
stack build # if you're using Stack
cabal build # if you're using Cabal directly
This will do a normal build without LiquidHaskell active. To build and verify with LiquidHaskell, run one of:
stack build --flag liquidhaskell-cabal-demo:liquidhaskell # if you're using Stack
cabal configure -fliquidhaskell && cabal build # if you're using Cabal directly
