--- *mini.clue* Show next key clues
---
--- MIT License Copyright (c) 2023 Evgeni Chasnovski
--- Features:
--- - Implement custom key query process to reach target key combination:
--- - Starts after customizable opt-in triggers (mode + keys).
---
--- - Each key press narrows down set of possible targets.
--- Pressing `<BS>` removes previous user entry.
--- Pressing `<Esc>` or `<C-c>` leads to an early stop.
--- Doesn't depend on |'timeoutlen'| and has basic support for |'langmap'|.
---
--- - Ends when there is at most one target left or user pressed `<CR>`.
--- Results into emulating pressing all query keys plus possible postkeys.
---
--- - Show window (after configurable delay) with clues. It lists available
--- next keys along with their descriptions (auto generated from descriptions
--- present keymaps and user-supplied clues; preferring the former).
---
--- - Configurable "postkeys" for key combinations - keys which will be emulated
--- after combination is reached during key query process.
---
--- - Provide customizable sets of clues for common built-in keys/concepts:
--- - `g` key.
--- - `z` key.
--- - Window commands.
--- - Built-in completion.
--- - Marks.
--- - Registers.
---
--- - Lua functions to disable/enable triggers globally or per buffer.
---
--- For more details see:
--- - |MiniClue-key-query-process|.
--- - |MiniClue-examples|.
--- - |MiniClue.config|.
--- - |MiniClue.gen_clues|.
---
--- Notes:
--- - There is no functionality to create mappings while defining clues.
--- This is done to clearly separate these two different actions.
--- The best suggested practice is to manually create mappings with
--- descriptions (`desc` field in options), as they will be automatically
--- used inside clue window.
---
--- - Triggers are implemented as special buffer-local mappings. This leads to
--- several caveats:
--- - They will override same regular buffer-local mappings and have
--- precedence over global one.
---
--- Example: having set `<C-w>` as Normal mode trigger means that
--- there should not be another `<C-w>` mapping.
---
--- - They need to be the latest created buffer-local mappings or they will
--- not function properly. Most common indicator of this is that some
--- mapping starts to work only after clue window is shown.
---
--- Example: `g` is set as Normal mode trigger, but `gcc` from |mini.comment|
--- doesn't work right away. This is probably because there are some
--- other buffer-local mappings starting with `g` which were created after
--- mapping for `g` trigger. Most common places for this are in LSP server's
--- `on_attach` or during tree-sitter start in buffer.
---
--- To check if trigger is the most recent buffer-local mapping, execute
--- `:<mode-char>map <trigger-keys>` (like `:nmap g` for previous example).
--- Mapping for trigger should be the first listed.
---
--- This module makes the best effort to work out of the box and cover
--- most common cases, but it is not foolproof. The solution here is to
--- ensure that triggers are created after making all buffer-local mappings:
--- run either |MiniClue.setup()| or |MiniClue.ensure_buf_triggers()|.
---
--- - Descriptions from existing mappings take precedence over user-supplied
--- clues. This is to ensure that information shown in clue window is as
--- relevant as possible. To add/customize description of an already existing
--- mapping, use |MiniClue.set_mapping_desc()|.
---
--- - Due to technical difficulties, there is no foolproof support for
--- Operator-pending mode triggers (like `a`/`i` from |mini.ai|):
--- - Doesn't work as part of a command in "temporary Normal mode" (like
--- after |i_CTRL-O|) due to implementation difficulties.
--- - Can have unexpected behavior with custom operators.
---
--- - Has (mostly solved) issues with macros:
--- - All triggers are disabled during macro recording due to technical
--- reasons.
--- - The `@` and `Q` keys are specially mapped inside |MiniClue.setup()|
--- (if the key is not already mapped) to temporarily disable triggers.
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.clue').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniClue`
--- which you can use for scripting or manually (with `:lua MiniClue.*`).
---
--- Config table NEEDS TO HAVE TRIGGERS CONFIGURED, none is set up by default.
---
--- See |MiniClue.config| for available config settings.
---
--- You can override runtime config settings (like clues or window options)
--- locally to a buffer inside `vim.b.miniclue_config` which should have same
--- structure as `MiniClue.config`. See |mini.nvim-buffer-local-config| for
--- more details.
---
--- # Comparisons ~
---
--- - [folke/which-key.nvim](https://github.com/folke/which-key.nvim):
--- - Both have the same main goal: show available next keys along with
--- their customizable descriptions.
--- - Has different UI and content layout.
--- - Allows creating mappings inside its configuration, while this module
--- doesn't have this by design (to clearly separate two different tasks).
--- - Doesn't allow creating submodes, while this module does (via `postkeys`).
---
--- - [anuvyklack/hydra.nvim](https://github.com/anuvyklack/hydra.nvim):
--- - Both allow creating submodes: state which starts at certain key
--- combination; treats some keys differently; ends after `<Esc>`.
--- - Doesn't show information about available next keys (outside of
--- submodes), while that is this module's main goal.
---
--- # Highlight groups ~
--- *MiniClue-hl-groups*
---
--- - `MiniClueBorder` - window border.
--- - `MiniClueDescGroup` - group description in clue window.
--- - `MiniClueDescSingle` - single target description in clue window.
--- - `MiniClueNextKey` - next key label in clue window.
--- - `MiniClueNextKeyWithPostkeys` - next key label with postkeys in clue window.
--- - `MiniClueSeparator` - separator in clue window.
--- - `MiniClueTitle` - window title.
---
--- To change any highlight group, set it directly with |nvim_set_hl()|.
---
--- # Disabling ~
---
--- To disable creating triggers, set `vim.g.miniclue_disable` (globally) or
--- `vim.b.miniclue_disable` (for a buffer) to `true`. Considering high number
--- of different scenarios and customization intentions, writing exact rules
--- for disabling module's functionality is left to user. See
--- |mini.nvim-disabling-recipes| for common recipes.
---@tag MiniClue
--- # General info ~
---
--- This module implements custom key query process imitating a usual built-in
--- mechanism of user pressing keys in order to execute a mapping. General idea
--- is the same: narrow down key combinations until the target is reached.
---
--- Main goals of its existence are:
---
--- - Allow reaching certain mappings be independent of |'timeoutlen'|. That is,
--- there is no fixed timeout after which currently typed keys are executed.
---
--- - Enable automated showing of next key clues after user-supplied delay
--- (also independent of |'timeoutlen'|).
---
--- - Allow emulating configurable key presses after certain key combination is
--- reached. This granular control allows creating so called "submodes".
--- See more at |MiniClue-examples-submodes|.
---
--- This process is primarily designed for nested `<Leader>` mappings in Normal
--- mode but works in all other main modes: Visual, Insert, Operator-pending
--- (with caveats; no foolproof guarantees), Command-line, Terminal.
---
--- # Lifecycle ~
---
--- - Key query process starts when user types a trigger: certain keys in certain
--- mode. Those keys are put into key query as a single user input. All possible
--- mode key combinations are filtered to ones starting with the trigger keys.
---
--- Note: trigger is implemented as a regular mapping, so if it has at least
--- two keys, they should be pressed within |'timeoutlen'| milliseconds.
---
--- - Wait (indefinitely) for user to press a key. Advance depending on the key:
---
--- - Special key:
---
--- - If `<Esc>` or `<C-c>`, stop the process without any action.
---
--- - If `<CR>`, stop the process and execute current key query, meaning
--- emulate (with |nvim_feedkeys()|) user pressing those keys.
---
--- - If `<BS>`, remove previous user input from the query. If query becomes
--- empty, stop the process without any action.
---
--- - If a key for scrolling clue window (`scroll_down` / `scroll_up`
--- in `config.window`; `<C-d>` / `<C-u>` by default), scroll clue window
--- and wait for the next user key.
--- Note: if clue window is not shown, treated as a not special key.
---
--- - Not special key. Add key to the query while filtering all available
--- key combinations to start with the current key query. Advance:
---
--- - If there is a single available key combination matching current
--- key query, execute it.
---
--- - If there is no key combinations starting with the current query,
--- execute it. This, for instance, allows a seamless execution of
--- operators in presence of a longer key combinations. Example: with
--- `g` as trigger in Normal mode and available mappings `gc` / `gcc`
--- (like from |mini.comment|), this allows typing `gcip` to comment
--- current paragraph, although there are no key combinations
--- starting with `gci`.
---
--- - Otherwise wait for the new user key press.
---
--- # Clue window ~
---
--- After initiating key query process and after each key press, a timer is
--- started to show a clue window: floating window with information about
--- available next keys along with their descriptions. Note: if window is
--- already shown, its content is updated right away.
---
--- Clues can have these types:
---
--- - "Terminal next key": when pressed, will lead to query execution.
---
--- - "Terminal next key with postkeys": when pressed, will lead to query
--- execution plus some configured postkeys.
---
--- - "Group next key": when pressed, will narrow down available key combinations
--- and wait for another key press. Note: can have configured description
--- (inside `config.clues`) or it will be auto generated based on the number of
--- available key combinations.

--- # Submodes ~
--- *MiniClue-examples-submodes*
---
--- Submode is a state initiated after pressing certain key combination ("prefix")
--- during which some keys are interpreted differently.
---
--- In this module submode can be implemented following these steps:
---
--- - Create mappings for each key inside submode. Left hand side of mappings
--- should consist from prefix followed by the key.
---
--- - Create clue for each key inside submode with `postkeys` value equal to
--- prefix. It would mean that after executing particular key combination from
--- this submode, pressing its prefix will be automatically emulated (leading
--- back to being inside submode).
---
--- - Register submode prefix (or some of its starting part) as trigger. Do not
--- register "overlapping" triggers, like `<Leader>` and `<Leader>m`.
---
--- ## Submode examples ~
---
--- - Submode for moving with |mini.move|:
--- - Press `<Leader>m` to start submode.
--- - Press any of `h`/`j`/`k`/`l` to move selection/line.
--- - Press `<Esc>` to stop submode.
---
--- The code: >lua
---
--- require('mini.move').setup({
--- mappings = {
--- left = '<Leader>mh',
--- right = '<Leader>ml',
--- down = '<Leader>mj',
--- up = '<Leader>mk',
--- line_left = '<Leader>mh',
--- line_right = '<Leader>ml',
--- line_down = '<Leader>mj',
--- line_up = '<Leader>mk',
--- },
--- })
---
--- require('mini.clue').setup({
--- triggers = {
--- -- This can also set up directly `<Leader>m` as a trigger, but make
--- -- sure to not also use `<Leader>`, as they would "overlap"
--- { mode = { 'n', 'x' }, keys = '<Leader>' },
--- },
--- clues = {
--- { mode = 'n', keys = '<Leader>m', desc = '+Move' },
---
--- { mode = { 'n', 'x' }, keys = '<Leader>mh', postkeys = '<Leader>m' },
--- { mode = { 'n', 'x' }, keys = '<Leader>mj', postkeys = '<Leader>m' },
--- { mode = { 'n', 'x' }, keys = '<Leader>mk', postkeys = '<Leader>m' },
--- { mode = { 'n', 'x' }, keys = '<Leader>ml', postkeys = '<Leader>m' },
--- },
--- })
--- <
--- - Submode for iterating buffers and windows with |mini.bracketed|:
--- - Press `[` or `]` to start key query process for certain direction.
--- - Press `b` / `w` to iterate buffers/windows until reach target one.
--- - Press `<Esc>` to stop submode.
---
--- The code: >lua
---

---
--- - To use |<Leader>| as part of the config (either as trigger or inside clues),
--- set it prior to running |MiniClue.setup()|.
---
--- - See |MiniClue-examples| for examples.
---
--- # Clues ~
---
--- `config.clues` is an array with extra information about key combinations.
--- Each element can be one of:
--- - Clue table.
--- - Array (possibly nested) of clue tables.
--- - Callable (function) returning either of the previous two.
---
--- A clue table is a table with the following fields:
--- - <mode> `(string|table)` - single character describing mode short-name of
--- key combination as in `nvim_set_keymap()` (`'n'`, `'x'`, `'i'`, `'o'`, `'c'`, etc.),
--- or a array thereof.
--- - <keys> `(string)` - key combination for which clue will be shown.
--- "Human-readable" key names as in |key-notation| (like "<Leader>", "<Space>",
--- "<Tab>", etc.) are allowed.
--- - <desc> `(string|function|nil)` - optional key combination description which is
--- shown in clue window. If function, should return string description.
--- - <postkeys> `(string|nil)` - optional postkeys which will be executed
--- automatically after `keys`. Allows creation of submodes
--- (see |MiniClue-examples-submodes|).
---
--- Notes:
--- - Postkeys are literal simulation of keypresses with |nvim_feedkeys()|.
---
--- - Suggested approach to configuring clues is to create mappings with `desc`
--- field while supplying to `config.clues` only elements describing groups,
--- postkeys, and built-in mappings.
---
--- # Triggers ~
---
--- `config.triggers` is an array with information when |MiniClue-key-query-process|
--- should start. Each element is a trigger table with the fields <mode> and
--- <keys> which are treated the same as in clue table.
---
--- # Window ~
---
--- `config.window` defines behavior of clue window.
---
--- `config.window.delay` is a number of milliseconds after which clue window will
--- appear. Can be 0 to show immediately.
---
--- `config.window.config` is a table defining floating window characteristics
--- or a callable returning such table (will be called with identifier of
--- window's buffer already showing all clues). It should have the same
--- structure as in |nvim_open_win()| with the following enhancements:
--- - <width> field can be equal to `"auto"` leading to window width being
--- computed automatically based on its content. Default is fixed width of 30.
--- - <row> and <col> can be equal to `"auto"` in which case they will be
--- computed to "stick" to set anchor ("SE" by default; see |nvim_open_win()|).
--- This allows changing corner in which window is shown: >lua
---
--- -- Pick one anchor
--- local anchor = 'NW' -- top-left
--- local anchor = 'NE' -- top-right
--- local anchor = 'SW' -- bottom-left
--- local anchor = 'SE' -- bottom-right
---
--- require('mini.clue').setup({
--- window = {
--- config = { anchor = anchor, row = 'auto', col = 'auto' },
--- },
--- })
--- <
--- `config.window.scroll_down` / `config.window.scroll_up` are strings defining
--- keys which will scroll clue window down / up which is useful in case not
--- all clues fit in current window height. Set to empty string `''` to disable
--- either of them.
