gvim to custom highlight group in .vimrc not working
unix, vim
Solution
The problem with your code is that the `match` commands reference custom highlight group names that aren't defined yet. Those group names must be defined using e.g. `highlight UnwanttedTab ...` before you use them with `match`. The `autocmds` will only define the highlight group names using `highlight` after you've loaded any colorscheme.
This is a way to setup the highlight groups, first defining syntax highlighting with group names, then providing a match for those group names:
highlight UnwanttedTab ctermbg=red guibg=darkred
highlight TrailSpace guibg=red ctermbg=darkred
match UnwanttedTab /\t/
match TrailSpace / \+$/
The `autocmd` recommendation from the article is intended to prevent any colorschemes that you might load from clearing your custom highlight groups with `:highlight clear`.
Try combining the commands above with the `autocmd`, in your `.vimrc`:
highlight UnwanttedTab ctermbg=red guibg=darkred
highlight TrailSpace guibg=red ctermbg=darkred
match UnwanttedTab /\t/
match TrailSpace / \+$/
autocmd ColorScheme * highlight UnwanttedTab ctermbg=red guibg=darkred
autocmd ColorScheme * highlight TrailSpace guibg=red ctermbg=darkred
colorscheme torte
Problem
vim version 6.3 Trying to create a new highlight group to highlight tabs and trailing spaces. I only have these settings in .vimrc. ``` autocmd ColorScheme * highlight UnwanttedTab ctermbg=red guibg=darkred match UnwanttedTab /\t/ autocmd ColorScheme * highlight TrailSpace guibg=red ctermbg=darkred match TrailSpace / \+$/ colorscheme torte ``` But when launching vim, I got error like this: ``` line 1: E216: No such group or event: ColorScheme * highlight UnwanttedTab ctermbg=red guibg=darkred line 2: E28: No such highlight group name: UnwanttedTab /\t/ line 3: E216: No such group or event: ColorScheme * highlight TrailSpace guibg=red ctermbg=darkred line 4: E28: No such highlight group name: TrailSpace / \+$/ ``` I was following this guide and using autocmd to prevent my highlight settings to be cleared. But still can't get to work. Does anyone know what could be wrong?
