haskell-shortcut-fusion-generation

This program takes in a file in containing 1 GADT declaration and will output a generated fold and build function similar to an ADT's Deriving Foldable for the GADT.

Setup

  1. Download The Haskell Platform (ghc, cabal, etc): https://www.haskell.org/platform/
  2. Update the Cabal package list: Run cabal update
  3. Clone the project to a local folder
  4. Install the project and its dependencies. Run cabal install. This will install all external dependencies needed and compile the project, installing it to a PATH discoverable location.

With the project configured and installed, you can now run it from anywhere on your commandline.

Use

scf-gen infile outfile

You may have to use the executable directly at ./dist/builder/scf-gen/scf-gen

The infile must be a valid text file containing only a GADT declaration. You can find a few examples in the tests/ directory.
