USAGE                                                           *paper-tonic-usage*

                                                              *paper-tonic.group()*
`paper-tonic`.group({group_name})                                  *paper-tonic-group()*

	Convert a pre-existing |highlight-group| into a format that |paper-tonic|
	recognizes.

	Note: the |highlight-group| must have been either:
		- |:highlight|ed.
		- |paper-tonic-highlight|ed.

	Parameters: ~
		{group_name}  A `string` which is the |highlight-group| to convert.

	Return: ~
		- A `table` which can be used as the {attributes} parameter for
		  |paper-tonic.highlight()|.

	Example: ~
>
	local paper-tonic = require('paper-tonic')

	-- get the 'Error' highlight group
	local hl_error = paper-tonic.group('Error')

	-- Define 'ErrorMsg' as foreground = background of 'Error'
	paper-tonic.highlight('ErrorMsg', {fg=hl_error.bg, bg=BG})

                                                          *paper-tonic.highlight()*
`paper-tonic`.highlight({group}, {attributes})                 *paper-tonic-highlight()*

	Highlight some {group} according to its {attributes}.

	Note: this method is intended to be used instead of |:highlight|.

	Parameters: ~
		{group}       A `string` which is the |highlight-group| to |:highlight|.
		{attributes}  A |lua| `table` which follows this format: >
		{
			-- The color for the background; or `NONE`, `FG` or `BG`
			bg = <color>,

			-- The color for the foreground; or `NONE`, `FG` or `BG`
			fg = <color>

			-- The |highlight-blend| value, if one is desired.
			[, blend = <integer>]

			-- Style can be from |attr-list|.
			-- It can also have a color, and/or multiple <cterm>s.
			[, style = <cterm>|{<cterm> (, <cterm>) [color=<color>]} ]
		}
<
	Return: ~
		- Nothing.

	Example: ~
>
		local paper-tonic = require('paper-tonic')

		local yellow = {'#f0df33', 220, 'yellow'}

		-- Highlight a new group
		paper-tonic.highlight('Todo', {fg=yellow, style={'bold', 'underline'}})
		-- Link a grou
		paper-tonic.highlight('Identifier', 'Todo')

	Override the |terminal| colors with a new table of {terminal_ansi_colors}.

E5108: Error executing lua [string ":lua"]:1: module '<colorscheme>' not found ~

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

Override the highlighting of one specific highlight group in my init.vim? ~

When using this plugin, it is important to know that you cannot just run `:hi`
on a highlight group and expect that its changes will be retained. You must
attach them to the |ColorScheme| |autocmd-event|, as shown below: >
	packadd nvim-paper-tonic
	set termguicolors "optional

	" WRONG! Don't do this.
	hi! Error guifg=#000000 guibg=#FFFFFF

	" Do this instead.
	augroup Highlite
		" You can also use `paper-tonic.highlight()` instead of `:hi!`
		autocmd ColorScheme paper-tonic hi! Error guifg=#000000 guibg=#FFFFFF
	augroup end

	colorscheme paper-tonic
<

Of course, substitute "highlight" with the name of your colorscheme.
