tango.vim

A dark Vim/Neovim color scheme based on onedark.vim, with colors from the tango theme

Installation

1. Install the theme using your Vim plug-in manager of choice (or manually, by placing colors/tango.vim in your ~/.vim/colors/ directory and autoload/tango.vim in your ~/.vim/autoload/ directory.)

   The theme also supports being installed as a Vim 8 package. Simply clone this repository into ~/.vim/pack/*/opt/ (so that the local path to this README would end up being ~/.vim/pack/*/opt/tango.vim/README.md) and add packadd! tango.vim to your ~/.vimrc. (The * in the path can be any value; see :help packages for more information.)

2. If you use Vim in a terminal, do the following to test whether your terminal emulator supports 24-bit/"true" color, then add relevant ~/.vimrc configuration if so:

   Note: GUI (non-terminal) Vim will always display 24-bit color regardless of the configuration done in this step.

   Run the following snippet in your shell:

   printf "\x1b[38;2;255;100;0mTRUECOLOR\x1b[0m\n"

   If your terminal emulator does NOT display the word TRUECOLOR in red, it does not support 24-bit color. If you don't want to switch to a different terminal emulator that supports 24-bit color, proceed to step 3. (After installation, the g:tango_termcolors option may interest you.)

   If your terminal emulator displays the word TRUECOLOR in red, it supports 24-bit color, and you should add the following lines to your ~/.vimrc to enable 24-bit color terminal support inside Vim.

   (If you use tmux, be sure to view the tmux-related notes in the first few lines.)

   "Use 24-bit (true-color) mode in Vim/Neovim when outside tmux.
   "If you're using tmux version 2.2 or later, you can remove the outermost $TMUX check and use tmux's 24-bit color support
   "(see < http://sunaku.github.io/tmux-24bit-color.html#usage > for more information.)
   if (empty($TMUX))
     if (has("nvim"))
       "For Neovim 0.1.3 and 0.1.4 < https://github.com/neovim/neovim/pull/2198 >
       let $NVIM_TUI_ENABLE_TRUE_COLOR=1
     endif
     "For Neovim > 0.1.5 and Vim > patch 7.4.1799 < https://github.com/vim/vim/commit/61be73bb0f965a895bfb064ea3e55476ac175162 >

     if (has("termguicolors"))
       set termguicolors
     endif
   endif

3. Add the following to your ~/.vimrc (below any lines you may have added in steps 1 and 2):

   syntax on
   colorscheme tango

Options

Note: All options should be set before the `colorscheme tango

• g:tango_termcolors (see Troubleshooting (below) for more information about this option): Set to 256 for 256-color terminals (the default), or set to 16 to use your terminal emulator's native 16 colors.

• g:tango_terminal_italics: Set to 1 if your terminal emulator supports italics; 0 otherwise (the default).

• g:tango_disable_background: Set to 1 to disable the background for normal text (mainly so that the terminal emulator's transparency is not covered up); 0 to enable it (the default).
