Installation

Download with your favorite package manager.

use "EdenEast/nightfox.nvim" -- Packer
Plug 'EdenEast/nightfox.nvim' " Vim-Plug

Usage

Simply set the colorscheme with the builtin command :colorscheme

colorscheme nightfox
vim.cmd("colorscheme nightfox")

Configuration

There is no need to call setup if you don't require to change the default options and settings.

-- Default options
require('nightfox').setup({
  options = {
    -- Compiled file's destination location
    compile_path = vim.fn.stdpath("cache") .. "/nightfox",
    compile_file_suffix = "_compiled", -- Compiled file suffix
    transparent = false,    -- Disable setting background
    terminal_colors = true, -- Set terminal colors (vim.g.terminal_color_*) used in `:terminal`
    dim_inactive = false,   -- Non focused panes set to alternative background
    styles = {              -- Style to be applied to different syntax groups
      comments = "NONE",    -- Value is any valid attr-list value `:help attr-list`
      functions = "NONE",
      keywords = "NONE",
      numbers = "NONE",
      strings = "NONE",
      types = "NONE",
      variables = "NONE",
    },
    inverse = {             -- Inverse highlight for different types
      match_paren = false,
      visual = false,
      search = false,
    },
    modules = {             -- List of various plugins and additional options
      -- ...
    },
  }
})

-- setup must be called before loading
vim.cmd("colorscheme nightfox")

If you would like to change any of the default options above you only have to define the options that change. If an option is not present in your options table the default option will be used. For example if chaning the styles of certain syntax is the only desired change then your options table would look like:

require('nightfox').setup({
  options = {
    styles = {
      commnets = "italic",
      keywords = "bold"
      types = "italic,bold",
    }
  }
})

To see a detailed explanation of nightfox's config settings consult either the builtin help :help nightfox or Usage.

Modules

Nightfox's modules store configuration information for various plugins and other neovim modules. To enable a module either set the module to true or if the module has additional configuration information set enable to true.

To see a list of modules check, see Usage or :help for more information.

Customize pallets and groups

You can change the color pallet and the highlight group of nightfox. Here is a brief example:

-- Pallets are the base color defines of a colorscheme.
-- You can override these pallets for each colorscheme defined by nightfox
local pallets = {
  nightfox = {
    -- Each pallet defines these colors:
    --   black, red, green, yellow, blue, magenta, cyan, white, orange, pink
    --
    -- These colors have 3 shades: base, bright, and dim
    --
    -- Defining just a color defines it's base color
    red = "#c94f6d",
  },
  dayfox = {
    -- Defining multiple shades is done by passing a table
    blue = { base = "#4d688e", bright = "#4e75aa", dim = "#485e7d", }
  },
  nordfox = {
    -- A pallet also defines the following:
    --   bg0, bg1, bg2, bg3, bg4, fg0, fg1, fg2, fg3, sel0, sel1, comment
    --
    -- These are the different foreground and background shades used by the theme.
    -- The base bg and fg is 1, 0 is normally the dark alternative. The others are
    -- incrementally lighter versions.
    bg1 = "#2e3440",

    -- sel is different types of selection colors.
    sel0 = "#3e4a5b", -- Popup bg, visual selection bg
    sel1 = "#4f6074", -- Popup sel bg, search bg

    -- comment is the definition of the comment color.
    comment = "#60728a",
  }
}

-- Spec's (specifications) are a mapping of pallets to logical groups that will be
-- used by the groups. Some examples of the groups that specs map would be:
--   - syntax groups (functions, types, keywords, ...)
--   - diagnostic groups (error, warning, info, hints)
--   - git groups (add, removed, changed)
--
-- You can override these just like pallets
local specs = {
  nightfox = {
    syntax = {
      -- Specs allow you to define a value using either a color or template. If the string does
      -- start with `#` the string will be used as the path of the pallet table. Defining just
      -- a color uses the base version of that color.
      keyword = "magenta",

      -- Adding either `.bright` or `.dim` will change the value
      conditional = "magenta.bright",
      number = "orange.dim",
    },
    git = {
      -- A color define can also be used
      changed = "#f4a261",
    }
  }
}

-- Groups are the highlight group definitions. The keys of this table are the name of the highlight
-- groups that will be overridden. The value is a table with the following values:
--   - fg, bg, style, sp, link,
--
-- Just like `spec` groups support templates. This time the template is based on a spec object.
local groups = {
  -- By default nightfox links some groups together. `CursorColumn` is one of these groups. When overriding
  -- Make sure `link` is cleared to `""` so that the link will be removed.
  CursorColumn = { bg = "sel0", link = "" },

  -- Specs are used for the template. Specs have their pallet's as a field that can be accessed
  IncSearch = { bg = "pallet.cyan" },
}

require("nightfox").setup({ pallets = pallets, specs = specs, groups = groups })

-- setup must be called before loading
vim.cmd("colorscheme nightfox")

To get more information check out Usage or the help file :help nightfox for more detailed information.

Api

Nightfox exposes some Api's and utility classes that let you fetch data from nightfox.

Pallets

You can get the pallets used by each colorscheme:

-- Returns a table with each colorscheme and the pallet associated with it
local pallets = require('nightfox.pallet').load()

-- Returns the pallet of the specified colorscheme
local pallet = require('nightfox.pallet').load("nightfox")

print(vim.inspect(pallet.red))
-- {
--   base = "#c94f6d",
--   bright = "#d16983",
--   dim = "#ab435d",
-- }

See Usage for more information on pallets.

Specs

You can get the spec used by each colorscheme:

-- Returns a table with each colorscheme and the spec associated with it
local specs require('nightfox.spec').load()

-- Returns the spec of the specified colorscheme
local spec = require('nightfox.spec').load("nightfox")

print(vim.inspect(spec.git))
-- {
--   add = "#81b29a",
--   changed = "#dbc074",
--   removed = "#c94f6d"
-- }

See Usage for more information on specs.

Color lib

Nightfox uses a color library internally to manipulate colors. You can use this library as well.

local pallet = require('nightfox.pallet').load('nightfox')
local Color = require("nightfox.lib.color")

local bg = Color.from_hex(pallet.bg1)
local red = Color.from_hex("#ff0000")

-- Blend the bg with red. The blend factor is from 0 to 1
-- with 0 being full bg and 1 being full red
local red_bg = bg:blend(red, 0.2)

print(red_bg:to_css())
-- "#471c26"

-- Brighten bg by adding 10 to the value of the color as a hsv
local alt_bg = bg:brighten(10)
print(vim.inspect(alt_bg:to_hsv()))
-- {
--   hue = 213.91304347826,
--   saturation = 47.916666666667,
--   value = 28.823529411765
-- }

There are a lot of useful functions to manipulate and work with colors in different color spaces. See Usage for more information on Color.

Compile

Nightfox is a highly customizable and configurable colorscheme. There are endless ways to customize nightfox. This does however come at the cost of complexity and execution time. Nightfox can pre compute the results of your configuration and store the results in a compiled lua file. After nightfox use these precached values to set it's highlights.

By default nightfox writes the compiled results into the system's cache directory. On unix this is $XDG_CACHE_HOME/nvim/nightfox and on windows this is %localappdata%\\Temp\\nvim\\nightfox.

Nightfox provides functions to work with the nightfox compiler.

local nightfox = require('nightfox')

-- Create/update the compile files
nightfox.compile()

-- Delete compiled files
nightfox.clean()

Nightfox provides the following commands that wrap these functions above:

:NightfoxCompile
:NightfoxClean

Supported Plugins

Status lines

Lualine checks the value of vim.g.colors_name (set when using :colorscheme command) to determine the theme to load. Set your colorscheme before calling setup.

vim.cmd("colorscheme nightfox")
require('lualine').setup({ ... })

Extra

There are extra configuration files for the following:
