Description:
simplified view on the haskell-src-exts AST; documentation
This package provides a shim for haskell-src-exts (HSE), exposing the same AST but without annotations, using ghc's pattern synonyms. . This package is useful for synthesizing and manipulating HSE ASTs that don't carry source location information. It may also aid in porting packages from haskell-src-exts 1.17 to 1.18, but it is not a drop-in replacement for the old annotation-free AST. . This package provides the documentation for a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
