ghc-justdoit: a GHC plugin to write the code for you
=========================================
This is a prototype of a code synthesis plugin for GHC, which uses LJT proof
search to instantiate a type.
Synopsis
--------
{-# OPTIONS_GHC -fplugin=GHC.JustDoIt.Plugin #-}
module Test where
import GHC.JustDoIt
foo :: ((a -> r) -> r) -> (a -> ((b -> r) -> r)) -> ((b -> r) -> r)
foo = (…)
Missing bits
------------
* The LJT might not be complete, due to insufficient backtracking.
* The implementation is very much unoptimized.
* It returns one solution, but not necessary the “best” one. But what is the “best” one?
* It ignores any recursive type, so it cannot do anything with lists. It would be much more useful if it could do some best-effort thing here as well.
If someone wants to pick it up from here, that’d be great!
