Preview window not showing up when selecting completition. #2333

Closed joaquinlpereyra closed 7 years ago

joaquinlpereyra commented 7 years ago

Hello! Lately, I've been having an strange issue with YouCompleteMe: the preview window won't show up when selecting a completition when on a Python file (haven't tested on anything else), as one would expect. The logs don't show any weird behavior. I was afraid this was me messing up my .vimrc, so I tried with a totally blank .vimrc file, just Vundle and YCM, no luck. I even tried to force it with a let g:ycm_add_preview_to_completeopt = 1. Doesn't work either :(

I'm on Arch Linux, all up to date. Test case: a python file, select complettion, no preview window showed up.

Thanks for any help you can provide!

let g:ycm_add_preview_to_completeopt = 1

This has been automagically fixed right after posting this issue. So weird.
