--- *mini.icons* Icon provider

--- *MiniIcons*

--- MIT License Copyright (c) 2024 Evgeni Chasnovski

---

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

---

--- Features:

---

--- - Provide icons with their highlighting via a single |MiniIcons.get()| for

--- various categories: filetype, file/directory path, extension, operating

--- system, LSP kind values. Icons and category defaults can be overridden.

---

--- - Configurable styles: "glyph" (icon glyphs) or "ascii" (non-glyph fallback).

---

--- - Fixed set of highlight groups (linked to built-in groups by default) for

--- better blend with color scheme.

---

--- - Caching for maximum performance.

---

--- - Integration with |vim.filetype.add()| and |vim.filetype.match()|.

---

--- - Mocking methods of 'nvim-tree/nvim-web-devicons' for better integrations

--- with plugins outside 'mini.nvim'. See |MiniIcons.mock_nvim_web_devicons()|.

---

--- - Tweaking built-in maps for "LSP kind" to include icons. In particular, this

--- makes |mini.completion| use icons in LSP step. See |MiniIcons.tweak_lsp_kind()|.

---

--- Notes:

---

--- - It is not a goal to become a collection of icons for as much use cases as

--- possible. There are specific criteria for icon data to be included as

--- built-in in each category (see |MiniIcons.get()|).

--- The main supported category is "filetype".

---

--- Recommendations for plugin authors using 'mini.icons' as a dependency:

---

--- - Check if `_G.MiniIcons` table is present (which means that user explicitly

--- enabled 'mini.icons') and provide icons only if it is.

---

--- - Use |MiniIcons.get()| function to get icon string and more data about it.

---

--- - For file icons prefer using full path instead of relative or only basename.

--- It makes a difference if path matches pattern that uses parent directories.

--- The |MiniIcons.config| has an example of that.

---

--- # Dependencies ~

---

--- Suggested dependencies:

---

--- - Terminal emulator that supports showing special utf8 glyphs, possibly with

--- "overflow" view (displaying is done not in one but two visual cells).

--- Most modern feature-rich terminal emulators support this out of the box:

--- WezTerm, Kitty, Alacritty, iTerm2, Ghostty.

--- Not having "overflow" feature only results into smaller icons.

--- Not having support for special utf8 glyphs will result into seemingly

--- random symbols (or question mark squares) instead of icon glyphs.

---

--- - Font that supports Nerd Fonts (https://www.nerdfonts.com) icons from

--- version 3.0.0+ (in particular `nf-md-*` class).

--- This should be configured on terminal emulator level either by using font

--- patched with Nerd Fonts icons or using `NerdFontsSymbolsOnly` font as

--- a fallback for glyphs that are not supported in main font.

---

--- If using terminal emulator and/or font with icon support is impossible, use

--- `config.style = 'ascii'`. It will use a (less visually appealing) set of

--- non-glyph icons.

---

--- # Setup ~

---

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

--- with your `config` table). It will create global Lua table `MiniIcons` which you

--- can use for scripting or manually (with `:lua MiniIcons.*`).

---

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

---

--- # Comparisons ~

---

--- - 'nvim-tree/nvim-web-devicons' (for users):

--- - Sets individual colors to each icon with separate specific highlight

--- groups, while this modules uses fixed set of highlight groups.

--- This makes it easier to customize in bulk and actually blend with any

--- color scheme.

---

--- - This module prefers richer set of `nf-md-*` (from "Material design" set)

--- Nerd Fonts icons while 'nvim-web-devicons' mostly prefers `nf-dev-*`

--- (from "devicons" set).

---

--- - Supported categories are slightly different (with much overlap).

---

--- - Both support customization of any icon. Only this module supports

--- customization of default ones per supported category.

---

--- - Using this module can occasionally result in small delays when used

--- synchronously for many times to get icons for not typical files (like

--- in |mini.files|). This is due to using |vim.filetype.match()| fallback and

--- is present only during first call, as value is cached for later uses.

---

--- - This module supports different icon styles (like "ascii" for when using

--- glyphs is not possible), while 'nvim-web-devicons' does not.

---

--- - This module provides |MiniIcons.mock_nvim_web_devicons()| function which

--- when called imitates installed 'nvim-web-devicons' plugin to support

--- other plugins which do not provide 'mini.icons' yet.

---

--- - 'nvim-tree/nvim-web-devicons' (for plugin developers):

--- - Both have main "get icon" type of function:

--- - Both return tuple of icon and highlight group strings.

---

--- - This module always returns icon data possibly falling back to

--- user's configured default, while 'nvim-web-devicons' is able to

--- return `nil`. This module's approach is more aligned with the most

--- common use case of always showing an icon instead or near some data.

--- There is a third returned value indicating if output is a result of

--- a fallback (see |MiniIcons.get()|).

---

--- - This module uses |vim.filetype.match()| as a fallback for "file"

--- and "extension" categories, while 'nvim-web-devicons' completely

--- relies on the manually maintained tables of supported filenames

--- and extensions.

--- Using fallback results in a wider support and deeper integration

--- with Neovim's filetype detection at the cost of occasional slower

--- first call. The difference is reduced as much as is reasonable by

--- preferring faster file extension resolution over filetype matching.

---

--- - This module caches all its return values resulting in really fast

--- next same argument calls, while 'nvim-web-devicons' doesn't do that.

---

--- - This module works with full file/directory paths as input.

---

--- - Different sets of supported categories (see |MiniIcons.config|):

--- - Both support "file", "extension", "filetype", "operating system".

--- Albeit in different volumes: 'nvim-web-devicons' covers more

--- cases for "operating system", while this module has better eventual

--- coverage for other cases.

---

--- - This module supports "directory" and "lsp" categories.

---

--- - 'nvim-web-devicons' covers "desktop environment" and "window

--- management" categories. This modules does not include them due to

--- relatively low demand.

---

--- - 'onsails/lspkind.nvim':

--- - Provides icons only for `CompletionItemKind`, while this module also has

--- icons for `SymbolKind` and other non-LSP categories.

--- - Provides dedicated formatting function for 'hrsh7th/nvim-cmp' while this

--- module intentionally does not (adding icons should be straightforward

--- to manually implement while anything else is out of scope).

---

--- # Highlight groups ~

---

--- Only the following set of highlight groups is used as icon highlight.

--- It is recommended that they all only define colored foreground:

---

--- * `MiniIconsAzure` - azure.

--- * `MiniIconsBlue` - blue.

--- * `MiniIconsCyan` - cyan.

--- * `MiniIconsGreen` - green.

--- * `MiniIconsGrey` - grey.

--- * `MiniIconsOrange` - orange.

--- * `MiniIconsPurple` - purple.

--- * `MiniIconsRed` - red.

--- * `MiniIconsYellow` - yellow.

---

--- To change any highlight group, modify it directly with |:highlight|.

--- <

MiniIcons.setup = function(config)

end

--- Module config

---

--- Default values:

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

---@text # Style ~

---

--- `config.style` is a string defining which icon style to use. It can be:

--- - `'glyph'` (default) - use glyph icons (like 󰈔 and 󰉋 ).

--- - `'ascii'` - use fallback ASCII-compatible icons. Those are computed as

--- an upper first character of the icon's resolved name inside its category.

--- Examples: >lua

---

--- MiniIcons.get('file', 'Makefile') -- Has `'M'` as icon

--- MiniIcons.get('extension', 'lua') -- Has `'L'` as icon

--- MiniIcons.get('file', 'file.lua') -- Has `'L'` as icon; it is resolved to

--- -- come from 'lua' 'extension' category

--- MiniIcons.get('file', 'myfile') -- Has `'F'` as icon; it is resolved to

--- -- come from 'file' 'default' category

--- <

--- # Customization per category ~

---

--- The following entries can be used to customize icons for supported categories:

--- - `config.default`

--- - `config.directory`

--- - `config.extension`

--- - `config.file`

--- - `config.filetype`

--- - `config.lsp`

--- - `config.os`

---

--- Customization should be done by supplying a table with <glyph> (icon glyph)

--- and/or <hl> (name of highlight group) string fields as a value for an icon

--- name entry. Example: >lua

---

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

--- default = {

--- -- Override default glyph for "file" category (reuse highlight group)

--- file = { glyph = '󰈤' },

--- },

--- extension = {

--- -- Override highlight group (not necessary from 'mini.icons')

--- lua = { hl = 'Special' },

---

--- -- Add icons for custom extension. This will also be used in

--- -- 'file' category for input like 'file.my.ext'.

--- ['my.ext'] = { glyph = '󰻲', hl = 'MiniIconsRed' },

--- },

--- })

--- <

--- Notes:

--- - These customizations only take effect inside |MiniIcons.setup()| call.

--- Changing interactively via `:lua MiniIcons.config.xxx = { ... }` does not work

--- for performance reasons.

--- - Use lower case names for categories which are matched ignoring case.

--- See |MiniIcons.get()| for more details.

---

--- # Using extension during file resolution ~

---

--- `config.use_file_extension` is a function which can be used to control which

--- extensions will be considered as a source of icon data during "file" category

--- resolution (see |MiniIcons.get()| for more details).

--- Default: function which always returns `true` (i.e. consider all extensions).

---

--- Will be called once for the biggest suffix after dot found in the file name.

--- The arguments will be `ext` (found extension; lowercase) and `file` (input for

--- which icon is computed; as is). Should explicitly return `true` if `ext` is to

--- be considered (i.e. call `MiniIcons.get('extension', ext)` and use its

--- output if it is not default). Otherwise extension won't be even considered.

---

--- The primary use case for this setting is to ensure that some extensions are

--- ignored in order for resolution to reach |vim.filetype.match()| stage. This

--- is needed if there is a set up filetype detection for files with recognizable

--- extension and conflicting icons (which you want to use). Note: if problematic

--- filetype detection involves only known in advance file names, prefer using

--- `config.file` customization.

---

--- Example: >lua

---

--- -- Built-in filetype detection recognizes files like "queries/.*%.scm"

--- -- as "query" filetype. However, without special setup, 'mini.icons' will

--- -- use "scm" extension to resolve as Scheme file. Here is a setup to ignore

--- -- "scm" extension and completely rely on `vim.filetype.match()` fallback.

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

--- -- Check last letters explicitly to account for dots in file name

--- use_file_extension = function(ext) return ext:sub(-3) ~= 'scm' end

--- })

---

--- -- Another common choices for extensions to ignore: "yml", "json", "txt".

--- <

MiniIcons.config = {

-- Icon style: 'glyph' or 'ascii'

style = 'glyph',

-- Customize per category. See `:h MiniIcons.config` for details.

default = {},

directory = {},

--minidoc_afterlines_end

--- Get icon data

---

--- Usage example: >lua

---

--- -- Results into `icon='󰢱'`, `hl='MiniIconsAzure'`, `is_default=false`

--- local icon, hl, is_default = MiniIcons.get('file', 'file.lua')

--- <

--- Notes:

--- - Always returns some data, even if icon name is not explicitly supported

--- within target category. Category "default" is used as a fallback. Use third

--- output value to check if this particular case is a result of a fallback.

---

--- - Glyphs are explicitly preferred (when reasonable) from a richer set of

--- `nf-md-*` class ("Material design" set) of Nerd Fonts icons.

---

--- - Output is cached after the first call to increase performance of next calls

--- with same arguments. To reset cache, call |MiniIcons.setup()|.

---

--- - To increase first call performance for "extension" and "file" categories,

--- add frequently used values in |MiniIcons.config|. They will be preferred

--- over executing |vim.filetype.match()|.

---

--- - Matching icon name for "file" and "directory" categories is done exactly

--- and respecting case. Others are done ignoring case.

---

---@param category string Category name. Supported categories:

--- - `'default'` - icon data used as fallback for any category.

--- Icon names:

--- - <Input>: any supported category name.

--- - <Built-in>: only supported category names.

---

--- Examples: >lua

---

--- MiniIcons.get('default', 'file')

--- <

--- - `'directory'` - icon data for directory path.

--- Icon names:

--- - <Input>: any string, but only basename is used. Works with not present

--- paths (no check is done).

--- - <Built-in>: popular directory names not tied to language/software

--- (with few notable exceptions like Neovim, Git, etc.).

---

--- Examples: >lua

---

--- -- All of these will result in the same output

--- MiniIcons.get('directory', '.config')

--- MiniIcons.get('directory', '~/.config')

--- MiniIcons.get('directory', '/home/user/.config')

---

--- -- Results in different output

--- MiniIcons.get('directory', '.Config')

--- <

--- - `'extension'` - icon data for extension.

--- Icon names:

--- - <Input>: any string (without extra dot prefix).

--- - <Built-in>: popular extensions without associated filetype plus a set

--- for which filetype detection gives not good enough result.

---

--- Icon data is attempted to be resolved in the following order:

--- - List of user configured and built-in extensions (for better results).

--- Run `:=MiniIcons.list('extension')` to see them.

--- Used also if present as suffix after the dot (widest one preferred).

--- - Filetype as a result of |vim.filetype.match()| with placeholder

--- file name. Uses icon data from "filetype" category.

---

--- Examples: >lua

---

--- -- All of these will result in the same output

--- MiniIcons.get('extension', 'lua')

--- MiniIcons.get('extension', 'LUA')

--- MiniIcons.get('extension', 'my.lua')

--- <

--- - `'file'` - icon data for file path.

--- Icon names:

--- - <Input>: any string. Works with not present paths (no check is done).

--- - <Built-in>: popular file names not tied to language/software

--- (with few notable exceptions like Neovim, Git, etc.) plus a set which

--- has recognizable extension but has special detectable filetype.

---

--- Icon data is attempted to be resolved in the following order:

--- - List of user configured and built-in file names (matched to basename

--- of the input exactly). Run `:=MiniIcons.list('file')` to see them.

--- - Basename extension:

--- - Matched directly as `get('extension', ext)`, where `ext` is the

--- widest suffix after the dot.

--- - Considered only if `config.use_file_extension` returned `true`.

--- - Only recognizable extensions (i.e. not default fallback) are used.

--- - Filetype as a result of |vim.filetype.match()| with full input (not

--- basename) as `filename`. Uses icon data from "filetype" category.

---

--- Examples: >lua

---

--- -- All of these will result in the same output

--- MiniIcons.get('file', 'init.lua')

--- MiniIcons.get('file', '~/.config/nvim/init.lua')

--- MiniIcons.get('file', '/home/user/.config/nvim/init.lua')

---

--- -- Results in different output

--- MiniIcons.get('file', 'Init.lua')

--- MiniIcons.get('file', 'init.LUA')

---

--- -- Respects full path input in `vim.filetype.match()`

--- MiniIcons.get('file', '.git/info/attributes')

--- <

--- - `'filetype'` - icon data for 'filetype' values.

--- Icon names:

--- - <Input>: any string.

--- - <Built-in>: any filetype that is reasonably used in Neovim ecosystem.

--- This category is intended as a widest net for supporting use cases.

--- Users are encouraged to have a specific filetype detection set up.

---

--- Examples: >lua

---

--- MiniIcons.get('filetype', 'lua')

--- MiniIcons.get('filetype', 'help')

--- MiniIcons.get('filetype', 'minifiles')

--- <

--- - `'lsp'` - icon data for various "LSP kind" values.

--- Icon names:

--- - <Input>: any string.

--- - <Built-in>: only namesspace entries from LSP specification that are

--- can be displayed to user. Like `CompletionItemKind`, `SymbolKind`, etc.

---

--- Examples: >lua

---

--- MiniIcons.get('lsp', 'array')

--- MiniIcons.get('lsp', 'keyword')

--- <

--- - `'os'` - icon data for popular operating systems.

--- Icon names:

--- - <Input>: any string.

--- - <Built-in>: only operating systems which have `nf-md-*` class icon.

---

--- Examples: >lua

---

--- MiniIcons.get('os', 'linux')

--- MiniIcons.get('os', 'arch')

--- MiniIcons.get('os', 'macos')

--- <

---@param name string Icon name within category. Use |MiniIcons.list()| to get icon

--- names which are explicitly supported for specific category.

---

---@return ... Tuple of icon string, highlight group name it is suggested to be

--- highlighted with, and boolean indicating whether this icon was returned

--- as a result of fallback to default. Example: >lua

---

--- -- Results into `icon='󰢱'`, `hl='MiniIconsAzure'`, `is_default=false`

--- local icon, hl, is_default = MiniIcons.get('file', 'file.lua')

--- Tweak built-in LSP kind names

---

--- Update in place appropriate maps in |vim.lsp.protocol| (`CompletionItemKind`

--- Updating is done in one of these modes:

--- - Append: add icon after text.

--- - Prepend: add icon before text (default).

--- - Replace: use icon instead of text.

--- - Makes |mini.completion| show icons, as it uses built-in protocol map.

--- - Results in loading whole `vim.lsp` module, so might add significant amount

--- of time on startup. Call it lazily. For example, with |MiniDeps.later()|: >

-- number id in `cache_index`. Its purpose is to quickly get cache. Special

-- field `true` in each `category` table is made to contain an id of category

-- fallback icon data.

-- - `cache_index` is an array of "icon-hl-is_default" unique tables. Its

-- purpose is to store all unique return tuples per category.

-- - `cache_index_lookup` is nested and indexed by `hl-icon` with values being

-- number id in `cache_index`. Its purpose is to quickly add new "icon-hl"

-- tuple to cache.

-- Filetype icons. Keys are filetypes explicitly supported by Neovim core

-- (i.e. present in `getcompletion('', 'filetype')` except technical ones)

-- and filetypes from some popular plugins.

-- Rough process of how glyphs and icons are chosen:

-- - Try to balance usage of highlight groups.

-- - Prefer using the following Nerd Fonts classes (from best to worst):

-- - `nf-md-*` (UTF codes seem to be more thought through). It also has

-- correct double width in Kitty.

-- - `nf-dev-*` (more supported devicons).

-- - `nf-seti-*` (more up to date extensions).

-- - `nf-custom-*` (niche Nerd Fonts only glyphs).

-- - If filetype is present in 'nvim-web-devicons', use highlight group with

-- most similar hue (based on OKLCH color space with equally spaced grid as

-- in 'mini.hues' and chroma=3 for grey cutoff; adjust manually if needed).

-- - Sets that have same/close glyphs but maybe different highlights:

-- - Generic configuration filetypes (".*conf.*", ".*rc", if stated in

-- filetype file description, etc.) have same glyph.

-- - Similar language: assembly ("asm"), SQL, Perl, HTML, CSV, shell.

-- - Log files.

-- - Make / build system.

-- - Related to Internet/Web.

-- - For newly assigned icons use semantically close (first by filetype origin,

-- then by name) abstract icons with `nf-md-*` Nerd Fonts class.

-- - If no semantically close abstract icon present, use plain letter/digit

-- icon (based on the first filetype character) with highlight groups picked

-- randomly to achieve overall balance (trying to minimize maximum number of

-- glyph-hl duplicates).
