--[[ Introduction
	This template is designed to help vimmers create their own colorschemes
	without much effort.

	You will not need any additional tooling to run this file. Just open it
	in Neovim and follow the instructions— the colorscheme will generate
	be generated automatically.

	The process is divided in five steps:
	1. Rename the template,
	2. Edit your colorscheme's information,
	3. Define your colors,
	4. Define your highlight groups and links, and
	5. Sourcing your colorscheme.
]]

--[[ Step 1: renaming
	If this file is distributed with a colorscheme it's probably already named correctly
	and you can skip this step.

	If you forked/cloned/copied this repository to create your own colorscheme, you will have to
	rename this template to match the name of your colorscheme.

	NOTE: Neovim doesn't really care about whitespace in the name of the colorscheme but it does for
	filenames so make sure your filename doesn't have any whitespace character.

	| colorscheme name  | template filename |
	|:-----------------:|:-----------------:|
	| foobar            | foobar.lua        |
	| foo-bar           | foo-bar.lua       |
	| foo bar           | foo-bar.lua or    |
	| foo_bar           | foo_bar.lua       |
]]

--[[ Step 2: information
	Make sure the name of your colorscheme is unique and attractive.
]]

local name = 'highlite'

--[[ Step 3: colors
	Next you will define all of the colors that you will use for the color scheme.

	Each one should be made up of three parts:

```lua
	<color name> = { -- Give each color a distinctive name.
		<hex color code>, -- Hexadecimal color used in GVim/MacVim or 'NONE'.
		<256-bit color code>, -- Integer 0–255 used by terminals supporting 256 colors or 'NONE'.
		<16-bit color code> -- color name used by less capable color terminals, can be 'darkred',
		                       'red', 'darkgreen', 'green', 'darkyellow', 'yellow', 'darkblue',
		                       'blue', 'darkmagenta', 'magenta', 'black', 'darkgrey', 'grey',
		                       'white', or 'NONE'
	}
```

	If your colors are defined correctly, the resulting colorscheme is guaranteed
	to work in GVim (Windows/Linux), MacVim (MacOS), and any properly set up terminal emulator.

	NOTE: |Replace-mode| will probably be useful here.

local purple_light = {'#af60af', 63,  'magenta'}
local purple_dark  = {'#c700ff', 38,  'darkmagenta'}

--[[ Step 4: highlights
	You can define highlight groups like this:

```lua
	<highlight group name> = {
		bg=<color>, -- The color used for background color, or use 'NONE', 'fg' or 'bg'
		fg=<color>, -- The color used for foreground color, or use 'NONE', 'fg' or 'bg'
		 -- Style can be 'bold', 'italic', and more. See |attr-list| for more information.
		style=<cterm>
		-- style can also have a color, and/or multiple <cterm>s.
		style={<cterm> [, <cterm>] [color=<color>]})
	}
```

	The sample above tells Vim to render normal text in dark gray against a white
	background, without any other styling.

	Or you can link an highlight group to another. Here, 'Title' will inherit its style from
	'Normal':

```lua
	Title = {link='Normal'}
```

	In GUI Vim, there is an additional color for the undercurl used to
	highlight spelling mistakes:

```lua
	SpellBad = { -- ← name of the highlight group
		bg='NONE', -- background color
		fg=red, -- foureground color
		style={ -- the style
			'undercurl', -- undercurl (squiggly line)
			color=red -- the color of the undercurl
		}
	}
```

	If you weren't satisfied with undercurl, and also wanted another effect, you can
	add another one below 'undercurl' and it will be applied as well:

```lua
	SpellBad = { -- ← name of the highlight group
		bg='NONE', -- background color
		fg=red, -- foureground color
		style={ -- the style
			'undercurl', -- undercurl (squiggly line)
			'standout'
			color=red -- the color of the undercurl
		}
	}
```

	The sample above tells Vim to render badly spelled words in red against the current
	background, with a red undercurl.

	You can add any custom highlight group to the standard list below but you shouldn't
	remove any if you want a working colorscheme. Most of them are described under
	:help highlight-default, the others are taken from :help group-name. Both help sections
	are good reads, by the way.

	NOTE: |Replace-mode| will probably be useful here.

	NOTE: /As long as you do not remove any highlight groups or colors/, you can safely
	      ignore any highlight groups that are `link`ed others.
			For example, programming languages almost exclusively link to the 1st
			and 2nd sections, so as long as you define everything there you will automatically
			be defining the rest of the highlights.

--[[ Step 5: Terminal Colors
	Define the color palette used by :terminal when in GUI Vim
	or in TUI Vim when 'termguicolors' is enabled. If this list
	is empty or if it doesn't contain exactly 16 items, the corresponding
	Vim variable won't be set.

	The expected values are colors defined in step 3.

	Terminal emulators use a basic palette of 16 colors that can be
	addressed by CLI and TUI tools via their name or their index, from
	0 to 15. The list is not really standardized but it is generally
	assumed to look like this:

	 | Index  | Name          |
	 |:------:|:-------------:|
	 | 1      | black         |
	 | 2      | darkred       |
	 | 3      | darkgreen     |
	 | 4      | darkyellow    |
	 | 5      | darkblue      |
	 | 6      | darkmagenta   |
	 | 7      | darkcyan      |
	 | 8      | gray          |
	 | 9      | darkgray      |
	 | 10     | red           |
	 | 11     | green         |
	 | 12     | yellow        |
	 | 13     | blue          |
	 | 14     | magenta       |
	 | 15     | cyan          |
	 | 16     | white         |

	While you are certainly free to make colors 0 to 7 shades of blue,
	this will inevitably cause usability issues so… be careful.

--[[ Step 5: Sourcing
	When you wish to load your colorscheme, you will not use the `colorscheme` command like normal.

	Instead, you will source this file with `:luafile stdpath('config') . '/lua/<filename>.lua'`

	See `:help luafile` and `:help stdpath` for more information.

	These online resources can help you design your colorscheme:

	1. the xterm palette.
		* http://upload.wikimedia.org/wikipedia/en/1/15/Xterm_256color_chart.svg
	2. play with hexadecimal colors right in the address bar (currently down).
		* http://whatcolor.herokuapp.com/
	3. similar concept, fuzzier implementation.
		* http://color.hailpixel.com/
	4. similar concept, fancier implementation.
		* http://colourco.de/
	5. extract a palette from an image.
		* http://www.colr.org/
	6. search for 'word', get images and color palettes.
		* http://colores.manugarri.com/
	7. user-created palettes.
		* http://www.colourlovers.com/palettes
	8. a no-nonsense colorscheme generator.
		* http://www.pluaang.dk/color+scheme/
	9. Adobe's fancy colorscheme generator.
		* https://color.adobe.com/
	10. The classic 'Color Scheme Designer', rebranded.

	11. A very smart palette generator.

	A few general advices:

	* The Windows console is limited to the 16 so-called 'ANSI' colors but it used to
			have a few of them interverted which makes numbers impractical. Use color names
			instead of numbers: :help cterm-colors
		* The Windows console (yeah…) doesn't do italics, underlines or bolded text;
				it is limited to normal and reverse. Keep that in mind if you want
				your colorscheme to be usable in as many environments as possible by as many
				people as possible.
			* Actually, terminal emulators rarely do italics.
		* The Windows Terminal, however, is capable of more.
	* All of the terminal emulators in use these days allow their users to
		change the 16 so-called 'ANSI' colors. It is also possible on some platforms
		to change some or all of the 256 colors in the xterm palette. Don't take
		anything for granted.
	* When used against a light background, strong colors work better than muted
		ones. Light or dark doesn't really matters. Also, it is harder to discriminate
		between two similar colors on a light background.
	* Both strong and muted colors work well against a dark background. It is also
		easier to work with similar colors, but dark colors don't work at all.
	* Use as many text samples as possible. String-heavy languages may look completely
		different than keyword-heavy ones. This can have an impact on the usability
		of your colorscheme.
	* Most terminal emulators and terminal multiplexers currently in use on unix-like
		systems support 256 colors but they almost always default to a '$TERM' that tells
		Vim otherwise. Your users will need to make sure their terminal emulator/multiplexer
		is correctly set up if they want to enjoy the best possible experience.

	Many thanks to Barry Arthur (https://github.com/dahu) for the original idea.

	* You don't need to edit anything beyond this line. *
