ghc-ghc-exactprint

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.
Note: requires GHC 7.10.2 or later.
