Manipulating Haskell source

Haskell-Source with Extensions HSE, haskell-src-exts is an extension of the standard haskell-src package, and handles most registered syntactic extensions to Haskell, including

  • Multi-parameter type classes with functional dependencies
  • Indexed type families including associated types
  • Empty data declarations
  • GADTs
  • Implicit parameters
  • Template Haskell

and a few more. All extensions implemented in GHC are supported. Apart from these standard extensions, it also handles regular patterns as per the HaRP extension as well as HSX-style embedded XML syntax.
