gruvbox
|
|
=======
|
|
|
|
Retro groove color scheme for Vim.
|
|
|
|
Gruvbox is heavily inspired by [badwolf][1], [jellybeans][2] and [solarized][3].
|
|
|
|
Designed as a bright theme with pastel 'retro groove' colors and light/dark mode switching in the way of [solarized][3]. The main focus when developing Gruvbox is to keep colors easily distinguishable, contrast enough and still pleasant for the eyes.

Usage
|
|
-----
|
|
|
|
gruvbox comes in two modes, dark and light. To toggle between them with F5 you can add these to your .vimrc:
|
|
|
|
map <F5> :call ToggleBg()<CR>
|
|
function! ToggleBg()
|
|
if &background == 'dark'
|
|
set bg=light
|
|
else
|
|
set bg=dark
|
|
endif
|
|
|
|
colo gruvbox
|
|
endfunc
|
|
|
|
Just setting background to an appropriate value would work as well:
|
|
|
|
set bg=dark " Setting dark mode
|
|
set bg=light " Setting light mode
|
|
|
|
Since gruvbox inverts cursor color, when the search is highlighted, it could be awkward to determine current position. To get single cursor color while searching map gruvbox functions same way:
|
|
|
|
map <silent> <F4> :call gruvbox#hls_toggle()<CR>
|
|
imap <silent> <F4> <ESC>:call gruvbox#hls_toggle()<CR>a
|
|
vmap <silent> <F4> <ESC>:call gruvbox#hls_toggle()<CR>gv
|
|
|
|
nnoremap <silent> <CR> :call gruvbox#hls_hide()<CR><CR>
|
|
|
|
nnoremap * :let @/ = ""<CR>:call gruvbox#hls_show()<CR>*
|
|
nnoremap / :let @/ = ""<CR>:call gruvbox#hls_show()<CR>/
|
|
nnoremap ? :let @/ = ""<CR>:call gruvbox#hls_show()<CR>?
|
|
|
|
So you'll get `g:gruvbox_hls_cursor` (orange by default) cursor color when highlight search is on and inverted one otherwise. With such mappings you could also toggle search highlight on and off with F4 and hide it with Enter.

Terminal-specific
|
|
-----------------
|
|
|
|
(...).
|
|
|
|
* (Recommended) 256-color palette with gruvbox-palette shell script
|
|
* 16 colors palette mode with gruvbox terminal colorscheme
|
|
|
|
Troubleshooting
|
|
---------------
|
|
|
|
### Italics gets inverted (terminal)
|
|
|
|
Most terminals doesn't allow italics so the text that must be italicized goes inverted. To prevent that disable `g:gruvbox_italic` option.
|
|
|
|
### Effect of gruvbox_256palette.sh gets reset on Alt-Tab
|
|
|
|
That's known issue with Ubuntu GTK-themes. Refer [†][10] for more details. Known affected terms are Gnome Terminal, Terminator and Lilyterm and probably more VTE-based. Though with Lilyterm option 'Dim text when inactive' set off everything works fine.
