#9751: add runMeta Hook or TcM variant of hscCompileCoreExprHook -------------------------------------+------------------------------------- Reporter: luite | Owner: luite Type: task | Status: new Priority: normal | Milestone: 7.10.1 Component: GHC API | 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: -------------------------------------+------------------------------------- GHCJS has to jump through hoops to make annotations work and to get the necessary information for linking a TH splice. The main reason is that `hscCompileCoreExprHook` does not expose the `TcM` environment. Easiest fix would be to add {{{#!hs hscCompileCoreExprTcMHook :: HscEnv -> SrcSpan -> CoreExpr -> TcM HValue }}} to `Hooks`, but it'd be better to hook `runMeta` instead. Unfortunately `runMeta` is polymorphic, so it could be more tricky. I'm going to see if I can hook `runMeta` in a reasonable way, and if I run out of time for 7.10.1, send a patch with `hscCompileCoreExprTcMHook` instead. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9751 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
