gruvbox
Retro groove color scheme for Vim.
Gruvbox is heavily inspired by badwolf, jellybeans and solarized.
Designed as a bright theme with pastel 'retro groove' colors and light/dark mode switching in the way of solarized. 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 <silent> <F5> :call gruvbox#bg_toggle()<CR>
imap <silent> <F5> <ESC>:call gruvbox#bg_toggle()<CR>a
vmap <silent> <F5> <ESC>:call gruvbox#bg_toggle()<CR>gv
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, it could be awkward to determine current position, when the search is highlighted. To get single cursor color while searching, map these 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 † 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.
Lighter colors with iTerm2

Configuration
g:gruvbox_bold
Enables bold text.

g:gruvbox_italic
Enables italic text.
default: 1
g:gruvbox_underline
Enables underlined text.
default: 1
g:gruvbox_undercurl
Enables undercurled text.
default: 1
g:gruvbox_termcolors
Uses 256-color palette (suitable to pair with gruvbox-palette shell script). If you're dissatisfied with that, set option value to 16 to fallback base colors to your terminal palette. Refer † for details.
default: 256
g:gruvbox_contrast
Possible values are soft, medium and hard.
default: medium
g:gruvbox_hls_cursor
Changes cursor background while search is highlighted. Possible values are any of gruvbox palette.

default: 1
g:gruvbox_invert_signs
Inverts GitGutter and Syntastic signs. Useful to rapidly focus on.

ToDo
- Filetype syntax highlighting (R, TeX and I'm still dissatisfied with CSS)
- Plugin support (MiniBufExplorer, Tagbar)
- Airline theme
