Introduction

nvim-deus is a colorscheme template repository for Neovim 0.5+.

This is the config I modify from vim-deus, inspired by @theniceboy

This template's defaults focus on:

1. Compatability with semantic highlighting.
   • I was using colorschemes that often did not provide enough highlight groups to provide distinction between tokens.
2. Visibility in any range of blue-light.
   • I use redshift often, and many colorschemes did not allow for me to see when I had lower color temperatures.

This template's design focuses on:

1. Ease of use and rapid development.
   • New features may simply be integrated with current configurations, rather than rewritten over them.
   • Merging with the upstream repository is simplified by GitHub, allowing you to select what new defaults to add.
   • It provides a large supply of defaults for plugins and programming languages.
     • Define a smaller set of "categorical" highlights (see Neovim's group-name help page) and many more will link automatically.
2. Inversion of Control
   • Changes made to the highlighting algorithm won't affect how you write your colorscheme.
   • New highlight group attributes which are unaccounted for in older versions will simply be ignored without errors due to Lua's tables.

Prerequisites

1. Neovim 0.5+

Installation

Creating Your Own

1. Fork this repository, or clone it with git clone https://github.com/Iron-E/nvim-highlite.
2. Follow the instructions in colors/deus.vim.
   • If you are on a Unix system, use the setup script like so:

   chmod +x ./setup.sh
   ./setup.sh deus <colorscheme>
   

   Where <colorscheme> is the name of your desired colorscheme.
   • If you are on Windows, rename the files manually.

Just The Defaults

1. Install a plugin manager such as vim-plug and use it to "plug" this repository.

   " vim-plug example
   Plug "tandy1229/nvim-deus"
   

2. Specify this colorscheme as your default colorscheme in the init.vim:

   " Enable 24-bit color output. Only do this IF your environment supports it.
   " This plugin is fully compatible with 8-bit, 16-bit, and 24-bit colors.
   set termguicolors
   " Use the colorscheme
   colorscheme deus
   

Usage

Examples

This repository in itself is an example of how to use nvim-deus. Aside from this, the following colorschemes are built using nvim-deus:

• (if you use this, open an issue and I'll add it here!)

As Dependency

Below is an example of how to use nvim-deus as a dependency.

• See :h deus-usage for more.

-- Import nvim-deus
local deus = require('deus')

-- First, define some colors
local red = {'#FF0000', 1, 'red'}
local black = {'#000000', 0, 'black'}
local white = {'#FFFFFF', 255, 'white'}

-- Highlight 'Identifier'
deus.highlight('Identifier', {bg=red, fg=black, style='bold'})

-- Highlight 'Function' conditionally according to background color.
deus.highlight('Function', {bg=black, fg=red, light={bg=white}})

-- Link 'Example' to 'Identifier'
deus.highlight('Example', 'Identifier')

-- You can also reference specific attributes of another highlight group.
deus.highlight('AnotherExample', {bg=deus.group'SpellBad'.bg, fg=white})

As Template

Below is an example of how to use nvim-deus as a template.

• See deus.vim for more.

-- First, define some colors
local red = {'#FF0000', 1, 'red'}
local black = {'#000000', 0, 'black'}
local white = {'#FFFFFF', 255, 'white'}

-- Next define some highlight groups.
local highlight_groups = {
	-- Any field which can be set to "NONE" doesn't need to be set, it will be automatically assumed to be "NONE".
	Identifier = {bg=red, fg=black, style='bold'},
	-- If your colorscheme should respond to multiple background settings, you can do that too:
	Function = {bg=black, fg=red, light={bg=white}},
	--[[ Note that light/dark differentiation is completely optional. ]]

	-- You can also reference specific attributes of another highlight group.
	SomethingElse = function(self) return {fg=self.Identifier.fg, bg=self.Function.bg} end,
}

-- The rest is mostly handled by the template.

FAQ

Why am I receiving E5108: Error executing lua [string ":lua"]:1: module '<colorscheme>' not found?

Ensure your colorscheme's base folder is in Neovim's rtp before sourcing.

What syntax files should I use for X language?

You can either use nvim-treesitter, nvim-polyglot, or one of the following:
