Can't see any annotations (Type hovers, Code completion, etc)

[bratfizyk]

As presented in the picture - only a small, empty box appears with no content at all (see above "getArgs" function).

I use ghc 8.0.2, ghc-mod 5.8.0 and my OS is Linux Mint 19. I've just installed the dependencies (intero QuickCheck stack-run) as well. Am I missing anything ?

I am seeing this same problem on Ubuntu Mate with stack-run, intero, and, quickcheck installed globally.

It looks like ...

• https://github.com/haskelly-dev/Haskelly/issues/55
• https://github.com/haskelly-dev/Haskelly/issues/17 ... and seems to be ... maybe a null-ref in InteroLocationDecoder.js (but I'm guessing) from the attached logfile. haskelly.log

Exact same problem here. Debian 9 x64, KDE. stack-run, intero and quickcheck installed locally.

% stack ghc -- --version
The Glorious Glasgow Haskell Compilation System, version 7.10.2

[nshcat]

I do have the exact same problem. Here is the log that is created: https://pastebin.com/rKx4CNf5

Ditto, but sometimes it turns into a "Type not available."

Edit: Ah, it stays empty if the code is not fully correct. When it is, it'll show info on hover for local functions, but not for anything from (for example) Data.Text.
