where to config the underline?

[chunyang-wen]

I am using rainbow with the default configuration. That means: install rainbow with vim-plug and set it

let g:rainbow_active = 1

aaa = 1
b = (aaa,)

I want to remove the underline, as it seems that it is not correct.

When I call :RainbowToggle, the underline is gone.

I have search google and try to read the vimscript of rainbow, but I found nothing useful.

• operators config?
• underline not found
• cterm: no suspicious clue found

Maybe you can find something useful in README.md of this repo (search guis and cterms), and from vim help (:h attr-list)

[chunyang-wen]

I‘d like to remove, not add attribute. I have search *.vim in rainbow, there seems no underline configuration.

You can read the README about troubleshooting, and use the tool to check which syntax rule is actived. Could that be spell checking?

[chunyang-wen]

Yes, it is the spell check. But I found that the configuration is different with the README.

'parentheses_options': 'contains=@Spell'

to turn off the spell checker.

I have add the spell related configuration in vimrc

set spell spelllang=en_us
hi clear SpellBad
hi SpellBad cterm=underline
hi clear SpellRare
hi SpellRare cterm=underline
hi clear SpellCap
hi SpellCap cterm=underline
hi clear SpellLocal
hi SpellLocal cterm=underline

to turn off the spell checker

But the configuration to explicitly turn off spell check in parentheses is 'parentheses_options': 'contains=@NoSpell'. ( And by default rainbow wouldn't modify the spell check option, that is, if you don't turn on the spell check explicitly, rainbow wouldn't turn it on for you.

I have same question. How to cancel spell check in the plugin vimrc:

let g:rainbow_active = 1
nmap <leader>p :RainbowToggle<cr> 

result:

The trick is , vim, by default, will check if there is any syntax rules about spell checking, if there is @Spell, then top level default will become no spell checking, and if there is @NoSpell, the default rule will become spell checking enabled...

So the solution is define your own top level spell checking default instead of let vim decide it for you.

I dont think its a good idea to use spell checker in brackets match plugin. I mean the plugin just display brackets with rainbow maybe better, keep it simple, or provide some options to user. Here is part of my .vimrc configuration maybe useful to others:

" set spell spelllang=en_us                       " turn of spell check

let g:rainbow_active = 1                            " active rainbow
nmap <leader>p :RainbowToggle<cr>     " set key map
