haskell-src-exts-1.19.1: Manipulating Haskell source: abstract syntax, lexer, parser, and pretty-printer

Haskell-Source with Extensions (HSE, haskell-src-exts) is a standalone parser for Haskell. In addition to standard Haskell, 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.
