libghc-ghc-exactprint-dev - 0.6.4-1+b3 main

Using the API Annotations available from GHC 7.10.2, this
library provides a means to round trip any code that can
be compiled by GHC, currently excluding lhs files.
.
It does this with a phased approach:
* Delta - converts GHC API Annotations into relative
offsets, indexed by SrcSpan
* Transform - functions to facilitate changes to
the AST, adjusting the annotations generated in the
Delta phase to suit the changes.
* Print - converts an AST and its annotations to
properly formatted source text.
* Pretty - adds annotations to an AST (fragment) so that
the output can be parsed back to the same AST.
.
This package provides a library for the Haskell programming language.
