--- *mini.hues* Generate configurable color scheme

--- *MiniHues*

---

--- MIT License Copyright (c) 2023 Evgeni Chasnovski

---

--- ==============================================================================

---

--- Features:

--- - Required to set two base colors: background and foreground.

--- Their shades and other non-base colors are computed to be as much

--- perceptually different as reasonably possible.

--- See |MiniHues.config| for setup inspiration.

---

--- - Configurable:

--- - Number of hues used for non-base colors (from 0 to 8).

--- - Saturation level ("low", "lowmedium", "medium", "mediumhigh", "high").

--- - Accent color used for some selected UI elements.

--- - Plugin integration (can be selectively enabled for faster startup).

---

--- - Random generator for base colors. See |MiniHues.gen_random_base_colors()|.

--- Powers |randomhue| color scheme.

---

--- - Lua function to compute palette used in color scheme.

--- See |MiniHues.make_palette()|.

---

--- Supported highlight groups:

--- - All built-in UI and syntax groups.

---

--- - Built-in Neovim LSP and diagnostic.

---

--- - Tree-sitter (|treesitter-highlight-groups|).

---

--- - LSP semantic tokens (|lsp-semantic-highlight|).

---

--- - Plugins (either with explicit definition or by verification that default

--- highlighting works appropriately):

--- - 'echasnovski/mini.nvim'

--- - 'akinsho/bufferline.nvim'

--- - 'anuvyklack/hydra.nvim'

--- # Setup ~

---

--- This module needs a setup with `require('mini.hues').setup({})` and

--- **mandatory `background` and `foreground` fields** (add more fields to fit

--- your taste). It will create global Lua table `MiniHues` which you can use

--- for scripting or manually (with `:lua MiniHues.*`).

---

--- See |MiniHues.config| for `config` structure and default values.

---

--- This module doesn't have runtime options, so using `vim.b.minihues_config`

--- will have no effect here.

---

--- Example:

--- >

--- require('mini.hues').setup({

--- background = '#11262d',

--- foreground = '#c0c8cc',

--- plugins = {

--- default = false,

--- ['echasnovski/mini.nvim'] = true,

--- },

--- })

--- <

--- # Notes ~

---

--- - Using `setup()` doesn't actually create a |colorscheme|. It basically

--- creates a coordinated set of |highlight|s. To create your own scheme:

--- - Put "myscheme.lua" file (name after your chosen theme name) inside

--- any "colors" directory reachable from 'runtimepath' ("colors" inside

--- your Neovim config directory is usually enough).

--- - Inside "myscheme.lua" call `require('mini.hues').setup()` with your

--- palette and only after that set |g:colors_name| to "myscheme".

---

--- - This module doesn't define |cterm-colors| for implementation simplicity.

--- Use |mini.colors| module, |MiniColors-colorscheme:add_cterm_attributes()|

--- in particular.

--- Random hue color scheme ~

---

--- This module comes with a pre-built color scheme but with a twist: every

--- `:colorscheme randomhue` call will result in a different (randomly yet

--- carefully selected) colors.

---

--- It is essentially a combination of calls to |MiniHues.setup()| and

--- |MiniHues.gen_random_base_colors()| with a slight adjustments for

--- 'background' value.

---

--- Activate it as regular |colorscheme|. Get currently active config with

--- `:lua print(vim.inspect(MiniHues.config))`.

---@tag randomhue

-- Module definition ==========================================================

local MiniHues = {}

local H = {}

--- Module setup

---

--- Main side effect is to create palette and apply it. Essentially, a combination

--- of |MiniHues.make_palette()| and |MiniHues.apply_palette()|.

---

---@usage >lua

--- require('mini.hues').setup({

--- -- Use config table as you like

--- -- Needs both `background` and `foreground` fields present

--- background = '#11262d',

--- foreground = '#c0c8cc',

--- })

--- <

MiniHues.setup = function(config)

-- Export module

_G.MiniHues = MiniHues

-- Setup config

config = H.setup_config(config)

-- Apply config

H.apply_config(config)

end

--- Module config

---

--- See |MiniHues.make_palette()| for more information about how certain

--- settings affect output color scheme.

---

--- Default values:

---@eval return MiniDoc.afterlines_to_code(MiniDoc.current.eval_section)

---@text # Options ~

---

--- ## Plugin integrations ~

---

--- `config.plugins` defines for which supported plugins highlight groups will

--- be created. Limiting number of integrations slightly decreases startup time.

--- It is a table with boolean (`true`/`false`) values which are applied as follows:

--- - If plugin name (as listed in |mini.hues|) has entry, it is used.

--- - Otherwise `config.plugins.default` is used.

---

--- Example which will load only "mini.nvim" integration:

--- >

--- require('mini.hues').setup({

--- background = '#11262d',

--- foreground = '#c0c8cc',

--- plugins = {

--- default = false,

--- ['echasnovski/mini.nvim'] = true,

--- },

--- })

---

--- # Examples ~

---

--- Here are some possible setup configurations (copy first line and then use

--- only one `setup` call): >

---

--- local setup = require('mini.hues').setup

---

--- -- Choose background and foreground

--- setup({ background = '#2f1c22', foreground = '#cdc4c6' }) -- red

--- setup({ background = '#2f1e16', foreground = '#cdc5c1' }) -- orange

--- setup({ background = '#282211', foreground = '#c9c6c0' }) -- yellow

--- setup({ background = '#1c2617', foreground = '#c4c8c2' }) -- green

--- setup({ background = '#112723', foreground = '#c0c9c7' }) -- cyan

--- setup({ background = '#11262d', foreground = '#c0c8cc' }) -- azure

--- setup({ background = '#1d2231', foreground = '#c4c6cd' }) -- blue

--- setup({ background = '#281e2c', foreground = '#c9c5cb' }) -- purple

---

--- -- Choose number of accent colors

--- setup({ background = '#11262d', foreground = '#c0c8cc', n_hues = 6 })

--- setup({ background = '#11262d', foreground = '#c0c8cc', n_hues = 4 })

--- setup({ background = '#11262d', foreground = '#c0c8cc', n_hues = 2 })

--- setup({ background = '#11262d', foreground = '#c0c8cc', n_hues = 0 })

---

--- -- Choose saturation of colored text

--- setup({ background = '#11262d', foreground = '#c0c8cc', saturation = 'low' })

--- setup({ background = '#11262d', foreground = '#c0c8cc', saturation = 'lowmedium' })

--- setup({ background = '#11262d', foreground = '#c0c8cc', saturation = 'medium' })

--- setup({ background = '#11262d', foreground = '#c0c8cc', saturation = 'mediumhigh' })

--- setup({ background = '#11262d', foreground = '#c0c8cc', saturation = 'high' })

---

--- -- Choose accent color

--- setup({ background = '#11262d', foreground = '#c0c8cc', accent = 'bg' })

--- setup({ background = '#11262d', foreground = '#c0c8cc', accent = 'red' })

--- setup({ background = '#11262d', foreground = '#c0c8cc', accent = 'yellow' })

--- Make palette

---

--- General idea of palette generation is that it is mostly based on color channel

--- information extracted from base colors (background and foreground).

---

--- All operations are done inside `Oklch` color space, meaning that each color

--- is defined by three numbers:

--- - Lightness (`l`) - number between 0 (black) and 100 (white) describing how

--- light is a color.

--- - Chroma (`c`) - positive number describing how colorful is a color (bigger

--- values - more colorful; 0 is gray).

--- - Hue (`h`) - periodic number in [0, 360) describing a value of "true color"

--- on color circle/wheel.

---

--- For more details about `Oklch` see |MiniColors-color-spaces| or

--- https://bottosson.github.io/posts/oklab/.

---

--- Algorithm overview ~

---

--- - Extract lightness, chroma, and hue of base colors.

---

--- - Generate reference lightness values:

--- - Background edge: 0 or 100, whichever is closest to background lightness.

--- - Foreground edge: 0 or 100, different from background edge.

--- - Middle: arithmetic mean of background and foreground lightness values.

---

--- - Compute background and foreground tints and shades by changing lightness

--- of background color: two colors closer to background lightness edge and

--- two closer to middle.

---

--- - Pick chroma value for non-base colors based on `config.saturation`.

---

--- - Generate hues for non-base colors:

--- - Fit an equidistant circular grid with `config.n_hues` points to be as

--- far from both background and foreground hues. This will ensure that

--- non-base colors are as different as possible from base ones (for

--- better visual perception).

--- Example: for background hue 0, foreground hue 180, and `config.n_hues` 2

--- the output grid will be `{ 90, 270 }`.

---

--- - For each hue of reference color (which itself is an equidistant grid

--- of 8 hues) compute the closest value from the grid. This allows

--- operating in same terms (like "red", "green") despite maybe actually

--- having less different hues.

---

--- - Compute for each hue two variants of non-base colors: with background and

--- foreground lightness values.

---

--- - Compute two variants of accent color (with background and foreground

--- lightness) based on `config.accent`.

---

--- Notes:

--- - Some output colors can have not exact values of generated Oklch channels.

--- This is due to actually computed colors being impossible to represent via

--- '#rrggbb' hex string. In this case a process called gamut clipping is done

--- to reduce lightness and chroma in optimal way while maintaining same hue.

--- For more information see |MiniColors-gamut-clip|.

---

--- - Not all colors are actually used in highlight groups and are present for the

--- sake of completeness.

---

---@param config table Configuration for palette. Same structure as |MiniHues.config|.

--- Needs to have <background> and <foreground> fields.

---

---@return table Palette with the following fields:

--- - <bg> and <fg> with supplied `background` and `foreground` colors.

--- - Fields like <bg_*> and <fg_*> are essentially <bg> and <fg> but with

--- different lightness values: `_edge`/`_edge2` - closer to edge lightness,

--- `_mid`/`_mid2` - closer to middle lightness.

--- - Fields for non-base colors (<red>, <orange>, <yellow>, <green>, <cyan>,

--- <azure>, <blue>, <purple>) have the same lightness as foreground.

--- - Fields for non-base colors with <_bg> suffix have the same lightness as

--- background.

--- - <accent> and <accent_bg> represent accent colors with foreground and

--- background lightness values.
