haskell mode: gtags doesn't work

[magthe]

Description :octocat:

gtags doens't work in haskell mode

I'm somewhat confused by the presence of the gtags functions in the mode menu, given that global, according to its own web site, doesn't support Haskell.

Reproduction guide :beetle:

• Start Emacs
• Open haskell source file
• Navigate to a function call site
• Press SPC m g d

Observed behaviour: :eyes: :broken_heart: If the gtags files are missing, they are sometimes generated. After that, nothing.

If the gtags files are already present, nothing happens.

Expected behaviour: :heart: :smile: I expect that I'm transported to the definition of the function I've placed the cursor on.

FWIW, dumb-jump should work with Haskell. That said, I don't know if spacemacs is configured by default to fallback to, or use, it with Haskell.

So the correct course of action here would be to remove the gtags functions from the haskell menu right? Can't see what can be done until global supports haskell.

@rgrinberg Yes, I think that's the correct course of action at this point.
