Interactive-Haskell hangs #10

Closed xificurC closed 9 years ago

xificurC commented 9 years ago

Hi there, I'm not sure if this is exactly company-ghc's fault but I don't know where else to go, so feel free to point me somewhere else if needed :) I'm working on the scheme48hours and interactive haskell hangs on me when I start a scheme repl from within the cabal repl. I have to kill ghc and then I either see this in Messages

Company: An error occurred in auto-begin
Wrong type argument: stringp, nil

or I get 1k lines of completions shown in the haskell process log. Either way I have to kill ghc and emacs starts responding only afterwards.

Steps to reproduce (on my machine at least):

In case you really go down testing this and want the code I have then here it is, the current master [0fc2d53] is the one you should clone.

To make the listing full, here are my versions:

My haskell-mode setting is now broken by recent haskell-mode's re-organization. I will fix the setting and try the steps hopefully soon .

I could generate the problem without company-mode. So I think it should be reported to haskell-mode.

The "Wrong type argument: stringp, nil" error is thrown from here. https://github.com/haskell/haskell-mode/blob/master/haskell-process.el#L265

company-capf calls it through completion-at-point-functions. Even without company-mode, M-x completion-at-point causes the same error.

I have no idea about the cause of the hang.

Hi, sorry for replying so late... Indeed M-x completion-at-point hangs for me as well. Going to report it in haskell-mode and see what happens. Thank you for your time!

Here is the answer I got from Chris Done if you wish to know the reasons behind this issue. Thank you for your help and feel free to mark this closed.

You're welcome. Thanks for the pointer.
