Readme for ghc-hs-meta-0.1.5.0

[back to package description]

ghc-hs-meta

Generate Template Haskell expressions from Haskell source code using the GHC parser. This package runs on GHC versions 8.10, 9.0, 9.2, 9.4, 9.6, 9.8 and 9.10.

Usage

Pass a String containing Haskell source code to parseExp. Example from the tests:

case parseExp "a @b" of
    Right exp -> exp `shouldBe` TH.AppTypeE (TH.VarE (TH.mkName "a")) (TH.VarT (TH.mkName "b"))
    Left (_, _, errMsg) -> error errMsg

See Hackage documentation for more documentation.

Thank you, PyF

This code originated from the excellent parser included in the PyF package. I extracted the relevant code and refactored/renamed things to be usable in a more general context. Without PyF, this could wouldn't have been possible. Thank you!
