#10842: "Reactive" Template Haskell -------------------------------------+------------------------------------- Reporter: MikeIzbicki | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Template Haskell | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: 9699 | Differential Revisions: -------------------------------------+------------------------------------- Comment (by luite): Should the callback be active for the current module or for something more? Beyond the current module would be hard to support in the presence of partial rebuilds. Should this be called for all declarations below the point adding the callback, or just for those added by TH? If this is to be called for everything, then this could end up being problematic for new language extensions that cannot yet be converted to a TH `Dec` . Also I'm a bit wary about having more higher order functions in the low- level `Q` API, since they're significantly harder to support in implementations where TH isn't run in the GHC address space (like GHCJS and the proposed out-of-process TH extension for stage1 (cross) compiler TH support). As far as I can tell, this particular extension would still be implementable though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10842#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
