Utilities to tie up tokens to an AST.

This library is currently experimental.

The GHC part is solid, since it has been migrated from HaRe.

The haskell-src-exts one is still in progress

This package provides a set of data structures to manage the tie-up between a Haskell AST and the underlying tokens, such that it explicitly captures the Haskell layout rules and original formatting. As a result changes can be made to the AST and the tokens will be updated so that the source file can be recreated with only the updated parts changed. This makes it easier to write Haskell source code modification programmes.
