#10250: API Annotations : add Locations in hsSyn where layout occurs -------------------------------------+------------------------------------- Reporter: alanz | Owner: Type: task | Status: closed Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.10.1 Resolution: fixed | Keywords: | ApiAnnotations Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | Phab:D815,Phab:D1370 -------------------------------------+------------------------------------- Changes (by bgamari): * status: patch => closed * resolution: => fixed Old description:
At the moment ghc-exactprint, which uses the GHC API Annotations to provide a framework for roundtripping Haskell source code with optional AST edits, has to implement a horrible workaround to manage the points where layout needs to be captured.
These are
MatchGroup HsDo HsCmdDo HsLet LetStmt HsCmdLet GRHSs
To provide a more natural representation, the contents subject to layout rules need to be wrapped in a SrcSpan.
