Togglebg from solarized changes to incorrect colorscheme

Question

I've installed solarized with the bundled togglebg.vim plugin.

In my vimrc I set background to light and colorscheme to solarized, so I have light background and matching font colors from solarized-light.

When I change background to dark in my vimrc and restart vim, it starts with dark background and matching colors from solarized-dark - as advertised.

But when I use togglebg, it changes background to dark (but not dark like in solarized, almost black) and to some different colorscheme. Manual :colorscheme solarized doesn't fix the problem. After running togglebg double it doesn't go back to first state, but to solarized-light scheme with the same almost black background.

I have only solarized with togglebg, ctrlP and Powerline installed.

Answer 1

If you want to toggle background, add this to your vimrc, (edit mapping according to what you like)

I use this on OS X 10.10.2 on iTerm

function! BgToggleSol()
  if &background == "light"
    execute ":set background=dark"
  else
    execute ":set background=light"
  endif
endfunction

nnoremap <leader>ct :call BgToggleSol()<cr>

Tip: Since you are using a mac, pasting using Command+V must be a pain. Add this to your vimrc as well

if &term =~ "xterm.*"
    let &t_ti = &t_ti . "\e[?2004h"
    let &t_te = "\e[?2004l" . &t_te
    function XTermPasteBegin(ret)
        set pastetoggle=<Esc>[201~
        set paste
        return a:ret
    endfunction
    map <expr> <Esc>[200~ XTermPasteBegin("i")
    imap <expr> <Esc>[200~ XTermPasteBegin("")
    cmap <Esc>[200~ <nop>
    cmap <Esc>[201~ <nop>
endif

First colorscheme solarized must be after let g:solarized_termcolors=256, and that may work.

If not. You should set xterm-256 color in preferences.

Bellow you can see the settings that works for me nicely. I don't use a keymap for toggle background, instead just use :set bg=light or :set bg=dark

" Pathogen plugins 
execute pathogen#infect()

filetype on
filetype indent on
filetype plugin on

" Enable syntax colors
syntax enable

" Background color from color  scheme
set background=dark
" set background=light

" Solarized scheme color preferences
let g:solarized_termcolors=256
let g:solarized_termtrans = 1
let g:solarized_degrade = 0
let g:solarized_bold = 1
let g:solarized_underline = 1
let g:solarized_italic = 1
let g:solarized_contrast = "normal"
let g:solarized_visibility= "normal"
colorscheme solarized
