==========



_nightfly_ is a dark midnight theme for modern Neovim and classic Vim.



Note, all _nightfly_ highlights in Neovim are implemented in Lua, whilst

highlights in Vim are implemented in legacy Vimscript.



:point_right: I maintain another dark theme named

[moonfly](https://github.com/bluz71/vim-moonfly-colors) which may be of

interest.

:zap: Requirements

------------------



_nightfly_ is a **GUI-only** colorscheme.



A GUI client or a modern terminal version of Vim or Neovim in a true-color

terminal is required. Details about true-color terminals are [listed

here](https://github.com/bluz71/vim-nightfly-colors#true-color-terminals).



_nightfly_ explicitly does **not** support the 256 color `cterm` version of Vim.



Installation

------------



Install the **bluz71/vim-nightfly-colors** colorscheme with your preferred

plugin manager.



[lazy.nvim](https://github.com/folke/lazy.nvim):



```lua

{ "bluz71/vim-nightfly-colors", name = "nightfly", lazy = false, priority = 1000 },

```



[vim-plug](https://github.com/junegunn/vim-plug):



```vim

Plug 'bluz71/vim-nightfly-colors', { 'as': 'nightfly' }

```



Usage

-----



Enable the colorscheme after the plugin declaration.



```vim

" Vimscript initialization file

colorscheme nightfly

```



```lua

-- Lua initialization file

vim.cmd [[colorscheme nightfly]]

```



Statusline

----------



- The _nightfly_ theme supports

  [lightline](https://github.com/itchyny/lightline.vim). To enable the

  _nightfly_ lightline theme please add the following to your

  initialization file:



```vim

let g:lightline = { 'colorscheme': 'nightfly' }

```



- The _nightfly_ theme supports

  [vim-airline](https://github.com/vim-airline/vim-airline). The _nightfly_

  theme will load once vim-airline starts.



- The _nightfly_ theme supports

  [Lualine](https://github.com/nvim-lualine/lualine.nvim). The

  _nightfly_ theme will automatically load once Lualine starts.



- My [linefly](https://github.com/bluz71/nvim-linefly) `statusline` plugin

  supports the _nightfly_ theme.



- Lastly, my legacy

  [mistfly-statusline](https://github.com/bluz71/vim-mistfly-statusline) plugin

  also supports the _nightfly_ theme.

---



### nightflyCursorColor



The `nightflyCursorColor` 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 initialization file:



```vim

" Vimscript initialization file

let g:nightflyCursorColor = v:true

```



```lua

-- Lua initialization file

vim.g.nightflyCursorColor = true

```



---



### nightflyItalics



The `nightflyItalics` option specifies whether to use italics for comments and

certain HTML elements in GUI versions of Vim. By default this option is

**enabled**. If you do not like the appearance of italics then add the following

to your initialization file:



```vim

" Vimscript initialization file

let g:nightflyItalics = v:false

```



```lua

-- Lua initialization file

vim.g.nightflyItalics = false

```



---



### nightflyNormalFloat



The `nightflyNormalFloat` option specifies whether to use nightfly background

and foreground colors in Neovim floating windows. By default this option is

**disabled**, hence, Neovim floating windows will usually be styled with popup

menu colors. If you would like to use nightfly colors instead then add the

following to your configuration:



```vim

" Vimscript initialization file

let g:nightflyNormalFloat = v:true

```



```lua

-- Lua initialization file

vim.g.nightflyNormalFloat = true

```



:bulb: If the above option is set then it is highly recommended to enable

floating window borders to distinguish between the edit and floating windows in

Neovim's LSP client, for example:



```lua

  vim.lsp.handlers['textDocument/hover'] = vim.lsp.with(

    vim.lsp.handlers.hover, {

      border = "single"

    }

  )

  vim.lsp.handlers['textDocument/signatureHelp'] = vim.lsp.with(

    vim.lsp.handlers.signatureHelp, {

      border = "single"

    }

  )

  vim.diagnostic.config({ float = { border = "single" } })

```



:bulb: Likewise, [nvim-cmp](https://github.com/hrsh7th/nvim-cmp) may be

configured as follows for nicer display when `g:nightflyNormalFloat` is enabled:



```lua

local winhighlight = {

  winhighlight = "Normal:NormalFloat,FloatBorder:FloatBorder,CursorLine:PmenuSel",

}

require('cmp').setup({

  window = {

    completion = cmp.config.window.bordered(winhighlight),

    documentation = cmp.config.window.bordered(winhighlight),

  }

})

```



---



### nightflyTerminalColors



The `nightflyTerminalColors` option specifies whether to use the nightfly color

palette in `:terminal` windows when `termguicolors` is set. By default this

option is **enabled**. If you prefer not to use the nightfly color palette for

the first 16 terminal colors then add the following to your initialization file:



```vim

" Vimscript initialization file

let g:nightflyTerminalColors = v:false

```



```lua

-- Lua initialization file

vim.g.nightflyTerminalColors = false

```



---



### nightflyTransparent



The `nightflyTransparent` option specifies whether to use an opaque or

transparent background in GUI versions of Vim. By default this option is

**disabled**. If you would like a transparent background then add the following

to your initialization file:



```vim

" Vimscript initialization file

let g:nightflyTransparent = v:true

```



```lua

-- Lua initialization file

vim.g.nightflyTransparent = true

```



---



### nightflyUndercurls



The `nightflyUndercurls` option specifies whether to use undercurls for

spelling and linting errors in GUI versions of Vim, including terminal Vim with

`termguicolors` set. By default this option is **enabled**. If you do not like

the appearance of undercurls then add the following to your initialization file:



```vim

" Vimscript initialization file

let g:nightflyUndercurls = v:false

```



```lua

-- Lua initialization file

vim.g.nightflyUndercurls = false

```



---



### nightflyUnderlineMatchParen



The `nightflyUnderlineMatchParen` option specifies whether to underline

matching parentheses. By default this option is **disabled**. If you want to

underline matching parentheses then add the following to your initialization

file:



```vim

" Vimscript initialization file

let g:nightflyUnderlineMatchParen = v:true

```



```lua

-- Lua initialization file

vim.g.nightflyUnderlineMatchParen = true

```



---



### nightflyVirtualTextColor



The `nightflyVirtualTextColor` option specifies whether to display diagnostic

virtual text in color. By default this option is **disabled**. If you want to

display diagnostic virtual text in color then add the following to your

initialization file:



```vim

" Vimscript initialization file

let g:nightflyVirtualTextColor = v:true

```



```lua

-- Lua initialization file

vim.g.nightflyVirtualTextColor = true

```



---



### nightflyWinSeparator



The `nightflyWinSeparator` option specifies the style of window separators:



- `0` will display no window separators



- `1` will display block separators; this is the default



- `2` will diplay line separators



For example, if line separators are desired then add the following to your

configuration:



```vim

" Vimscript initialization file

let g:nightflyWinSeparator = 2

```



```lua

-- Lua initialization file

vim.g.nightflyWinSeparator = 2

```



:gift: If using Neovim 0.7 (or later), the following configuration will improve

the look of line separators (if option `2` has been chosen) by selecting thicker

characters for the separators:



```vim

" Vimscript initialization file

set fillchars=horiz:━,horizup:┻,horizdown:┳,vert:┃,vertleft:┨,vertright:┣,verthoriz:╋

```



```lua

-- Lua initialization file

vim.opt.fillchars = { horiz = '━', horizup = '┻', horizdown = '┳', vert = '┃', vertleft = '┫', vertright = '┣', verthoriz = '╋', }

```



Overriding Highlights

---------------------



If a certain highlight of this theme does not suit then it is recommended to use

an `autocmd` to override that desired highlight.



For example, if one wishes to highlight functions in bold then simply add the

following to your initialization file prior to setting the colorscheme:



```vim

" Vimscript initialization file

augroup CustomHighlight

    autocmd!

    autocmd ColorScheme nightfly highlight Function guifg=#82aaff gui=bold

augroup END

```



```lua

-- Lua initialization file

local custom_highlight = vim.api.nvim_create_augroup("CustomHighlight", {})

vim.api.nvim_create_autocmd("ColorScheme", {

  pattern = "nightfly",

  callback = function()

    vim.api.nvim_set_hl(0, "Function", { fg = "#82aaff", bold = true })

  end,

  group = custom_highlight,

})

```



True Color Terminals

--------------------



Many modern terminals support [24-bit true

colors](https://gist.github.com/XVilka/8346728). Current versions of Vim &

Neovim on such terminals support true colors when `set termguicolors` is

enabled.



A list of popular terminals that support true colors:



- [iTerm2](http://www.iterm2.com)

- [Windows Terminal](https://github.com/Microsoft/Terminal)

- [Alacritty](https://github.com/alacritty/alacritty)

- [kitty](https://sw.kovidgoyal.net/kitty/index.html)

- [konsole](https://konsole.kde.org)

- [PuTTY](https://putty.org)

- [mintty](https://mintty.github.io)



On terminals that support true colors, and when `termguicolors` is set, the

_nightfly_ colorscheme will emit the correct theme colors.



For the _nightfly_ colorscheme to display correctly inside _tmux_ the following

setting will usually be required in _~/.tmux.conf_:



```

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

```



Vim, as against Neovim, inside _tmux_, will also require the following settings

be added to the `~/.vimrc` file:



```vim

let &t_8f = "\[38;2;%lu;%lu;%lum"

let &t_8b = "\[48;2;%lu;%lu;%lum"

```
