Presentation mode configuration does not make any changes

[geraldus]

If I set haskell-process-use-presentation-mode to t this make no difference if it is set to nil. E.g. no matter what value is used, when I run haskell-mode-show-type-at it shows me colourful type information in echo area, and also prints to *** Messages *** buffer.

I'm not sure what Presentation mode actually is, but I expected that Emacs will create some kind of popup instead of echoing type information when mentioned variable is set to t. Currently I have haskell-doc-mode enabled, which almost instantly replaces nice colourful type information from interactive haskell mode with plain colourless text; I hoped that presentation mode will help with this.

@chrisdone: Chris, can you comment on this issue?

[chrisdone]

Presentation mode currently just applies to haskell-process-do-info (i.e. C-c C-i). I don't think doc-mode interacts well with C-c C-t presently.

Oh, well, now I see what presentation mode is. I've opened it because description of this var states:

Use presentation mode to show things like type info instead of printing to the message area.

Thanks for clarification, I will wait for updates.

I can't promise anything for sure, I'll take a look of how haskell-process-do-info written and maybe try to make haskell-mode-show-type-at become aware of presentation mode too.

If so make it optional; I originally had types using presentation mode, but in the end I found it too heavy-weight to just see the type.
