libghc-ghc-exactprint-dev 0.6.4-1build1 (arm64 binary) in ubuntu noble

 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.
