moonfly is a dark color scheme for Vim and Neovim that has taken inspiration from:

• sunburst
• xoria256
• One Dark
• One
• monokai

Note, the moonfly color scheme does incrementally change from time to time, primarily in regards to language and plugin theming. However, the core color palette will not change; except the time I changed crimson (July 1 2017), sorry.

A simple companion statusline, vim-moonfly-statuline, is also available.

• C/C++
• Shell
• Python
• Ruby
• Crystal
• Elixir
• JavaScript
• CoffeeScript
• Markdown
• Go
• Rust
• Java

• NERDTree
• Tagbar
• Neomake
• CtrlP
• clever-f
• BufExplorer

Use your favoured plugin manager to install bluz71/vim-moonfly-colors then set the colorscheme in your vimrc file.

If using vim-plug do the following:

1. Add Plug 'bluz71/vim-moonfly-colors' to your vimrc
2. Run :PlugInstall
3. Add colorscheme moonfly to your vimrc, make sure this line appears after the Plug declaration.

The g:moonflyCursorLineNr option specifies whether to highlight the cursor line, as blue, in the number column if the relativenumber or cursorline settings are in effect. By default the cursor line will be highlighted as such.

To disable highlighting of the current cursor line in the number column please add the following to your vimrc:

let g:moonflyCursorLineNr = 0

The g:moonflySpellInverse option specifies whether to highlight spelling errors in bold reversed colors. By default spelling errors will be highlighted using colored undercurls. However, most (all?) terminals do not appear to support undercurls let alone colored undercurls, simple underlines are usually displayed. Note, GUI-based Vim's, such as gVim and Macvim, do correctly display colored undercurls.

To highlight spelling errors in bold inverse colors please add the following to your vimrc:

let g:moonflySpellInverse = 1

The g:moonflyCursorColor option specifies whether to color the cursor or not. By default the cursor will NOT be colored, if you prefer a colored cursor then add the following to your vimrc:

let g:moonflyCursorColor = 1

The g:moonflyTerminalColors option specifies whether to use the moonfly color palette in :terminal windows when termguicolors is set. By default this option is disabled, if you prefer to use the moonfly color palette for the first 16 colors then add the following to your vimrc:

let g:moonflyTerminalColors = 1

Many terminal programs, such as iTerm2 and termite, support 24-bit true colors. Modern versions of Vim and Neovim, on such terminals, support true colors when set termguicolors is enabled.

Caveat, Terminal.app on macOS and xterm on Unix do not support true colors.

On terminals that do support true colors, and when termguicolors is set, the moonfly color scheme will not require any terminal configuration to emit the correct moonfly colors.

For the true colors moonfly color scheme to display correctly inside tmux the following setting will be required in ~/.tmux.conf:

set -ga terminal-overrides ',xterm-256color:Tc'

Vim, as against Neovim, inside tmux, will also require the following setting be added to vimrc:

set t_8b=^[[48;2;%lu;%lu;%lum
set t_8f=^[[38;2;%lu;%lu;%lum

Note: ^[ in the above snippet is a real escape character; to insert it, enter Ctrl-v followed by Esc. Repeating, the above t_8* settings are not required for Neovim.

If consistency between Vim colors and $SHELL colors is important then I recommend proceeding with the 256-color configurations listed in the next section.

The moonfly Vim color scheme when used with Vim in a 256-color terminal requires the host terminal be setup with the moonfly color palette.

The host terminal must be configured for 256 colors, this usually means setting the terminal's type to xterm-256color or screen-256color when used inside tmux.

iterm2 users on macOS can import this color scheme.

xterm users on Linux can add the following snippet to their ~/.Xresources file and launch xterm with xterm -name xterm-moonfly. A complete Xresources file is available here

xterm-moonfly*background:  #080808
xterm-moonfly*foreground:  #b2b2b2
xterm-moonfly*color0:      #373c40
