Cannot get rid of persisting highlighting

Question

I switched from macos to linux and have spontaneous highlighting in my document. I tried to get rid of it by doing the following command without success:

hi clear
no syntax
nohlsearch
noh

The randomly highlighted pattern is for example in the following line written in python, the strings numpy and savetxt are highlighted:

#from numpy import savetxt

when I uncomment the the line, the highlighting disapears

from numpy import savetxt

Here is a screenshot of the highlighting:

The highlighting disappeared after inserting in the .vimrc:

set nospell

But but I thin it then anihi

late the command:

set spellang=en
set spell

int the .vimrc

What should I do?

Answer 1

Most probably you have set spell enabled which usually checks spelling in comments.

If you don't need it turn it off with :set nospell. Activate when you need it with :set spell.

To toggle use :set spell!.

Map it if you do it often, for example:

nnoremap yos :set spell!<CR>

Then yos will toggle spelling.
