No autocompletion candidates for symbols in current file

It is just not implemented.
company-ghc scans module import statements and browse the modules (ghc-modi browse).
There is no logic to scan or browse functions in the current file.

company-dabbrev-code with grouped backend can complete identifiers in the current file, thought it does not show the type signature.
e.g.

(add-to-list 'company-backends '(company-ghc :with company-dabbrev-code))

Awesome thanks a lot!

I would contribute a PR if I had the skills, but I'm a bit new to Haskell. I spent an hour looking for this feature, and would also love if it existed!

The following didn't work for me:

(with-eval-after-load 'company
  ;(setq ghc-debug t)
  (add-to-list 'company-backends '(company-ghc :with company-dabbrev-code)))

@freckletonj as you can see from C-h f, with-eval-after-load takes a FILE not a function name. So you want "company" instead of 'company, like this:

  (with-eval-after-load "company"
    (add-to-list 'company-backends '(company-ghc :with company-dabbrev-code)))

Depending on what other things you have, you might want to wrap the whole thing in a (with-eval-after-load "ghc" [as above]) as well. That works for me anyway.
