It's inherently fragile, and shouldn't be relied on in scripts - and if :b does anything funny, spell out the command! (There is a case to be made for explicitly defining short forms of commands - but that is not what :b is, and making this case should only be done in a new thread.)

I haven't thought about it this way. OK, so _this_ is the questionable decision: allowing the ambiguous shortcut.

Hi Prelude :b Control.Concurrent.MVar module 'Control.Concurrent.MVar' is not interpreted :b now defaults to :breakpoint, you want :browse Thanks Neil ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I ask because I want to write an omni-completion plugin for Vim to make Haskell hacking a bit nicer. You don't want to do that. The .hi files can expose internal implementation details that shouldn't be visible to callers of the library. (E.g., so that GHC can inline things across module boundaries.) What you want to play with is the :browse command. ;-) (Thinking about it... some kind of tool for easily producing a propper interface file that 3rd party tools can use would probably be quite a useful thing... I wonder how hard it would be to implement?) ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Hi Does anyone know if/where I can find a specification for the .hi files generated by GHC? I ask because I want to write an omni-completion plugin for Vim to make Haskell hacking a bit nicer. you might find it easier to use GHCi's :browse command Or you might want to try haddock with the --hoogle command. Similar thing, slightly different format - depends what suits you. Thanks Neil ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
