#9628: Add Annotations to the AST to simplify source to source conversions -------------------------------------+------------------------------------- Reporter: alanz | Owner: alanz Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.9 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: D297 | -------------------------------------+------------------------------------- Description changed by alanz: Old description:
Add Annotations to HsSyn to explicitly track the locations of all non- blank source code elements to allow tools to parse a Haskell file, modify the AST and then produce an updated version of the source preserving the layout for unchanged parts.
Discussion of the feature is at GhcAstAnnotations
Note: an early effort was at Phab:D297, but this was abandoned as unworkable.
