Signcolumn

[royyhlee]

My signcolumn doesn't look correct. Is there a way to fix this? Thanks!

I can't reproduce this, please provide:

1. Your vim version.
2. Minimal vimrc.
3. The output of :hi SignColumn when using minimal vimrc.

This is what I have:

1. Your vim version neovim v0.4.3

2. Minimal vimrc

call plug#begin() Plug 'airblade/vim-gitgutter' Plug 'tpope/vim-commentary' Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' } Plug 'junegunn/fzf.vim' Plug 'neoclide/coc.nvim', {'branch': 'release'} Plug 'sheerun/vim-polyglot' Plug 'sainnhe/edge' call plug#end()

if has("termguicolors") set termguicolors endif

set background=light let g:lightline = { 'colorscheme': 'edge' } let g:edge_disable_italic_comment = 1 colo edge

set number set tw=80 set cc=+1 set hidden set tabstop=2 set shiftwidth=2 set updatetime=100 set expandtab set si set ignorecase set smartcase set lazyredraw set showmatch

filetype plugin on filetype indent on

3. The output of `:hi SignColumn` when using minimal vimrc.

:hi SignColumn
SignColumn xxx ctermfg=4 ctermbg=248 guifg=#4b505b guibg=#eef1f4
links to LineNr

[sainnhe]

The problem is that SignColumn has been linked to LineNr which is not expected, the expected output should be:

:hi SignColumn
SignColumn     xxx ctermfg=4 ctermbg=248 guifg=#4b505b guibg=#eef1f4

This is caused by

Plug 'airblade/vim-gitgutter'

So it's not an issue of this color scheme, it's an issue of gitgutter. I don't understand why the author of gitgutter links SignColumn to LineNr.

To solve this problem, you can

1. Open an issue in airblade/vim-gitgutter
2. Use other plugin instead, for example: mhinz/vim-signify, neoclide/coc-git

Awesome, thank you for the info. I'll look more into it.

Actually the SignColumn is fine: the problem is with the background colour of the signs.

I don't understand why the author of gitgutter links SignColumn to LineNr.

vim-gitgutter defaults to linking SignColumn to LineNr because colour schemes often define them with different background colours, and lots of people opened issues wanting them to look the same. (The code is here.) Note that you can opt out of this.

Anyway, you can see that the resulting values for ctermfg, ctermbg, guifg, and guibg are all as expected.

As for why the signs' background colours are wrong – I will look into this further at airblade/vim-gitgutter#696.

Sorry, I misunderstood the colorscheme: I thought the sign column was supposed to be white, not grey; i.e. that the sign backgrounds were wrong, not the sign column.

As @sainnhe said, the problem was vim-gitgutter linking SignColumn to LineNr. This was put in 5 years ago when few plugins used signs and therefore most colorschemes at the time had ugly sign columns. Now the situation has changed – there are many plugins using signs and many carefully designed colorschemes – so it makes sense for vim-gitgutter not to adjust the SignColumn any more (https://github.com/airblade/vim-gitgutter/commit/0da302c28a08fe62c31c77ac854914affd2180b8).
