Override colorscheme

Question

I often find myself wanting to change just something little in a colorscheme, but i don't want to edit the original file. I tried putting my change in '~/.vim/after/colors/blah.vim', but that doesn't work for me.

---

Example, I want to change the CursorLine highlight in BusyBee.vim..

~/.vim/colors/BusyBee.vim

I create the file '~/.vim/after/colors/BusyBee.vim' and add this:

hi CursorLine    guibg=#000000 ctermbg=Black cterm=none

However, i don't see the change. Of course it works if i change the line in the originial BusyBee.vim, but like i said i'd prefer not to do that.

Doing...

:colo Busy<TAB>

Shows me...

BusyBee  BusyBee

Answer 1

Put

hi CursorLine    guibg=#000000 ctermbg=Black cterm=none

after your

colorscheme BusyBee

entry in your _vimrc.

Answer 2

I don't have 'colorscheme BusyBee' in my .vimrc. I like to switch colorscheme now and then, so i want to "fix" the actual theme.

I came up with this solution, not the prettiest, but whatever.

function! FixColorscheme() " {{{
    echo "fixing colorscheme"
    if has("gui_running")
        if (g:colors_name =~ "busybee")
            hi Folded        guibg=#001336 guifg=#003DAD gui=none
            hi CursorLine    guibg=#000000 ctermbg=Black cterm=none

        elseif (g:colors_name =~ "256-jungle")
            hi CursorLine    guibg=#000000 ctermbg=Black cterm=none

        elseif (g:colors_name =~ "xoria256")
            hi Folded        guibg=#001336 guifg=#003DAD gui=none cterm=none
            "hi Folded         ctermbg=234  ctermfg=25    cterm=none
        endif
    elseif &t_Co == 256
        if (g:colors_name =~ "busybee")
            hi Folded        guibg=#001336 guifg=#003DAD gui=none
            hi CursorLine    guibg=#000000 ctermbg=Black cterm=none

        elseif (g:colors_name =~ "256-jungle")
            hi CursorLine    guibg=#000000 ctermbg=Black cterm=none

        elseif (g:colors_name =~ "xoria256")
            hi Folded         ctermbg=234  ctermfg=25    cterm=none
            hi CursorLine    cterm=none
        "else
            "hi CursorLine     ctermbg=0                  cterm=none
        endif
    endif
    endfunction
" }}}

Run it automatically when changing color scheme.

augroup mycolorschemes
    au!
    au ColorScheme * call FixColorscheme()
augroup END

And this helps to load your favorite-scheme-of-the-week on startup. (eek!! the default!)

if iSFirstRun == 1
    echo "HI"
    colo xoria256
    call FixColors()
endif

.. and this at the very top of .vimrc

"" To let us set some settings only once. {{{
    if exists("isRunning")
        let isFirstRun = 0
    else
        let isFirstRun = 1
    endif
    let isRunning = 1
" }}}

Perhaps there already is something for this 'isFirstRun'?
