Haskell Source Extensions

haskell-src-exts is a package for handling and manipulating Haskell source code. It is a descendant of the haskell-src package that is part of the standard libraries, but extends this to support a number of syntactic extensions, e.g. MPTCs, fundeps, GADTs, TH etc. The aim is to support all extensions recognized by the community, as determined by what is implemented in compilers and tools.

Apart from the more standard extensions supported by e.g. GHC, haskell-src-exts provides support for HaRP (Haskell Regular Patterns) and HSX (Haskell Source with XML) syntax.

Package structure

The modules that comprise haskell-src-exts all reside in the hierarchic namespace Language.Haskell.Exts, or its more feature-rich sibling Language.Haskell.Exts.Annotated. Notable exposed modules include:
