#9628: Add Annotations to the AST to simplify source to source conversions -------------------------------------+------------------------------------- Reporter: alanz | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Two different kinds of annotation are proposed to be added to HsSyn 1. Additional elements to explictly track the location of all syntactic elements not currently tracked. In particular, locations of reserved words and punctuation. 2. A top-level type parameter that allows a tool-writer to thread an application-specific annotation through the syntax tree. These two could potentially be merged, if the default annotation parameter is capable of tracking the first category of information.
