searching for tickets

Hi devs, Previously, I could effectively use Google as a way to search for contents in tickets, with a query like > site:ghc.haskell.org/blah/blah/tickets > type families (I can't remember the exact URL, and Trac has been taken down so I can't figure

Re: Wiki search & pages

Wow! thank you so much for such a detailed reply, Ben. Makes me wish there was some way you could link to a blog entry of the current ongoing stuff and just write it down once in there as it happens rather than have to repeat it whenever someone asks to save you effort of repetition, but maybe

Re: [ambiguous occurrence bug?]

I'm guessing, but I suspect currently the only way to look up a symbol either requires explicit qualification of the symbol name or that the symbol be part of a class or instance declaration that implicitly qualifies method and associated type names. So for the implicit export list to retrieve the

Re: [ambiguous occurrence bug?]

No contradiction: "not those that are imported" means a module which imports names does not automatically re-export those names to other modules that import it. So T does indeed export "main", which is imported unqualified by Main and thereby causes an ambiguous occurrence. But if T had imported

[ambiguous occurrence bug?]

Sorry in advance if I should be posting questions of this kind elsewhere (please tell me if so!). Consider this two file program: ``` module T where main = undefined module Main where import T main = putStrLn "Hello world!" ``` Both 8.4.3 and 8.6.3 agree: ``` Main.hs:1:1: error: Ambiguous

Hello again, I just also noticed that the diagrams for the compiler pipeline seem to have disappeared. I refer to those diagrams all the time when I’m working on GHC, so I’d really like it if they could come back somehow. Julian ___ ghc-devs mailing
