Company gives “Wrong type argument” error message

[iquiw]

I pushed the fix as commit 9010952
Please try it.

Aside from this error, ghc-get-info seems not work in this case.
You might want to check *GHC Debug* buffer by setting ghc-debug to t.

The “Wrong type argument” error appears fixed; thanks!

I see no error messages in *GHC Debug*, though I don’t know what to
look for.

M-x ghc-show-info works?

[8573]

M-x ghc-show-info doesn’t seem to do anything.

[iquiw]

Check the return value of M-: ghc-process-running.
If it is t, I am afraid you hit the problem written in DanielG/ghc-mod#405 (comment)

It is appreciated if you could try the code written in the above issue comment.

ghc-process-running is nil when I first visit a Haskell source file,
and neither completing a word with company-ghc nor running
ghc-show-info seem to change the value of ghc-process-running to
anything other than nil.

It is appreciated if you could try the code written in the above issue
comment.

Having made the following change to ghc-mod…

diff --git i/elisp/ghc-process.el w/elisp/ghc-process.el

     ghc-process-results))

…company-ghc still works, ghc-show-info still doesn’t seem to do
anything, and ghc-process-running still stays nil.

Thanks for trying.
Then I have no idea what happens.

This is an issue in ghc-mod.
Maybe ghc-mod people can help.
