Error when opening Vim with no file #3

Closed cparadis6191 closed 9 years ago

I just switched from kien's plugin and ran into a problem. When opening Vim without a file (i.e. empty buffer) the following error occurs.

Error detected while processing function rainbow_parentheses#activate..<SNR>55_extract_colors..<SNR>55_blacklist:
line    2:
E411: highlight group not found: Normal
Press ENTER or type command to continue

I can replicate the problem with a very minimal vimrc (just vim-plug and the following).

" Rainbow Parentheses
let g:rainbow#max_level=16
let g:rainbow#pairs=[ ['(', ')'], ['[', ']'], ['{', '}'] ]
autocmd VimEnter * RainbowParentheses

The offending line:

https://github.com/junegunn/rainbow_parentheses.vim/blob/master/autoload/rainbow_parentheses.vim#L97

Changing the silent call to silent! seems to fix the problem (or hides it) but I'm no vimscript expert and I don't know if that could possibly break other things.

Thanks for any help.

Hi, thanks for the report. It looks your color scheme does not define Normal highlight group unlike most other colorschemes and silent! is a simple and valid fix to the problem. Thanks.

Ahh, thanks. I think the problem is that I don't have a colorscheme in Vim at all. I just use the default. It works now.
