#8025: "During interactive linking, GHCi couldn't find the following symbol" typechecker error with TemplateHaskell involved -------------------------------------+------------------------------------- Reporter: mojojojo | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 7.6.3 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86 Type of failure: Incorrect | Test Case: warning at compile-time | Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Duog, your approach seems like a very interesting compromise that I had not considered. Great work! There is the question of which `HscTarget` we want to use here. Arguably `HscInterpreted` is more appropriate as it is faster to generate, faster to link, and doesn't unexpected leave object files lying around. However, it unfortunately lacks support for unboxed tuples and sums, which may break some (I suspect quite small) fraction of programs. It would be interesting to characterize the difference. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8025#comment:9> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #11425: The GHC API doesn't provide a good hscTarget option for tooling

#11425: The GHC API doesn't provide a good hscTarget option for tooling -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: feature | Status: new request | Priority: high | Milestone: 8.2.1 Component: GHC API | Version: 7.10.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Tools like ghc-mod typically just want `TypecheckedModule`s. Sadly, the GHC API currently doesn't provide a good way to get at these in all cases (see this [https://github.com/DanielG/ghc-mod/issues/205|ghc-mod ticket]). Each of the options we offer are cursed with their own limitations (largely quoting from the ghc-mod ticket), == HscNothing == At first glance this looks like what you would want. But... * Pros * Doesn't generate code of any sort and is therefore rather lightweight * Cons * It lacks support for Template Haskell * Has trouble with `foreign export`s * [https://github.com/DanielG/ghc-mod/pull/145|Fails} to issue pattern match checker warnings == HscInterpreted == Okay, so `HscNothing` doesn't work. Maybe `HscInterpreted` is better? * Pros * Supports Template Haskell * Cons * Can't deal with unboxed tuples (#1257) * Slower as we need to produce unnecessary bytecode * Large memory footprint * Also can't deal with `foreign export`s == HscAsm == * Pros * Supports all compilable code * Cons * Slow * Produces `.o` files This is quite unfortunate. It seems like we need something in between `HscNothing` and `HscInterpreted` which is willing to use the interpreter to evaluate Template Haskell splices when necessary, but doesn't produce bytecode. Unfortunately it's unclear what to do about `foreign export` (but arguably most tools would be fine with some approximate representation). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11425> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #13521: Remove comments about API annotations

#13521: Remove comments about API annotations -------------------------------------+------------------------------------- Reporter: mpickering | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple ApiAnnotations | Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- There are lots of comments scattered around the code which look like {{{ -- - 'ApiAnnotation.AnnKeywordId's : 'ApiAnnotation.AnnOpen', -- 'ApiAnnotation.AnnClose', -- 'ApiAnnotation.AnnComma', -- 'ApiAnnotation.AnnType' -- For details on above see note [Api annotations] in ApiAnnotation }}} these are meant to tell you which annotations are associated with each syntax element. They were added in an heroic effort by alanz but are very hard to keep up to date and verify the correctness of. It would be much better if we had a programatic description of which annotations could be attached to which syntax elements and thankfully one already exists in `ghc-exactprint`. This library isn't in the source tree but I don't think this really matters, users can just depend on it if they want to use them. I think we should remove all these comments to clean up the source a bit and point users to `ghc-exactprint` from the `ApiAnnotations` page. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13521> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
