--- *mini.bracketed* Go forward/backward with square brackets
--- *MiniBracketed*
---
--- MIT License Copyright (c) 2023 Evgeni Chasnovski
---
--- ==============================================================================
---
--- Features:
--- - Configurable Lua functions to go forward/backward to a certain target.
--- Each function can be customized with:
--- - Direction. One of "forward", "backward", "first" (forward starting
--- from first one), "last" (backward starting from last one).
--- - Number of times to go.
--- - Whether to wrap on edges (going forward on last one goes to first).
--- - Some other target specific options.
---
--- - Mappings using square brackets. They are created using configurable
--- target suffix and can be selectively disabled.
---
--- Each mapping supports |[count]|. Mappings are created in Normal mode; for
--- targets which move cursor in current buffer also Visual and
--- Operator-pending (with dot-repeat) modes are supported.
---
--- Using `lower-suffix` and `upper-suffix` (lower and upper case suffix) for
--- a single target the following mappings are created:
--- - `[` + `upper-suffix` : go first.
--- - `[` + `lower-suffix` : go backward.
--- - `]` + `lower-suffix` : go forward.
--- - `]` + `upper-suffix` : go last.
---
--- - Supported targets (for more information see help for corresponding Lua
--- function):
---
--- `Target` `Mappings` `Lua function`
---
--- Buffer.......................... `[B` `[b` `]b` `]B` .... |MiniBracketed.buffer()|
---
--- Comment block................... `[C` `[c` `]c` `]C` .... |MiniBracketed.comment()|
---
--- Conflict marker................. `[X` `[x` `]x` `]X` .... |MiniBracketed.conflict()|
---
--- Diagnostic...................... `[D` `[d` `]d` `]D` .... |MiniBracketed.diagnostic()|
---
--- File on disk.................... `[F` `[f` `]f` `]F` .... |MiniBracketed.file()|
---
--- Indent change................... `[I` `[i` `]i` `]I` .... |MiniBracketed.indent()|
---
--- Jump from |jumplist|
--- inside current buffer........... `[J` `[j` `]j` `]J` .... |MiniBracketed.jump()|
---
--- Location from |location-list|..... `[L` `[l` `]l` `]L` .... |MiniBracketed.location()|
---
--- Old files....................... `[O` `[o` `]o` `]O` .... |MiniBracketed.oldfile()|
---
--- Quickfix entry from |Quickfix|.... `[Q` `[q` `]q` `]Q` .... |MiniBracketed.quickfix()|
---
--- Tree-sitter node and parents.... `[T` `[t` `]t` `]T` .... |MiniBracketed.treesitter()|
---
--- Undo states from specially
--- tracked linear history.......... `[U` `[u` `]u` `]U` .... |MiniBracketed.undo()|
---
--- Window in current tab........... `[W` `[w` `]w` `]W` .... |MiniBracketed.window()|
---
--- Yank selection replacing
--- latest put region................`[Y` `[y` `]y` `]Y` .... |MiniBracketed.yank()|
---
--- Notes:
--- - The `undo` target remaps |u| and |<C-R>| keys to register undo state
--- after undo and redo respectively. If this conflicts with your setup,
--- either disable `undo` target or make your remaps after calling
--- |MiniBracketed.setup()|. To use `undo` target, remap your undo/redo keys
--- to call |MiniBracketed.register_undo_state()| after the action.
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.bracketed').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniBracketed`
--- which you can use for scripting or manually (with `:lua MiniBracketed.*`).
---
--- See |MiniBracketed.config| for available config settings.
---
--- You can override runtime config settings (like target options) locally
--- to buffer inside `vim.b.minibracketed_config` which should have same structure
--- as `MiniBracketed.config`. See |mini.nvim-buffer-local-config| for more details.
---
--- # Comparisons ~
---
--- - 'tpope/vim-unimpaired':
--- - Supports buffer, conflict, file, location, and quickfix targets mostly
--- via built-in commands (like |:bprevious|, etc.) without configuration.
--- - Supports files from argument list and tags. This module does not.
--- - Doesn't support most other this module's targets (comment, indent, ...).
--- - 'mini.indentscope':
--- - Target |MiniBracketed.indent()| target can go to "first" and "last"
--- indent change. It also can go not only to line with smaller indent,
--- but also bigger or different one.
--- - Mappings from 'mini.indentscope' have more flexibility in computation of
--- indent scope, like how to treat empty lines near border or whether to
--- compute indent at cursor.
---
--- # Disabling ~
---
--- To disable, set `vim.g.minibracketed_disable` (globally) or
--- `vim.b.minibracketed_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.
---@diagnostic disable:luadoc-miss-type-name
---@alias __bracketed_direction string One of "first", "backward", "forward", "last".
---@alias __bracketed_add_to_jumplist - <add_to_jumplist> (`boolean`) - Whether to add current position to jumplist.
--- Default: `false`.
---@alias __bracketed_opts table|nil Options. A table with fields:
--- - <n_times> `(number)` - Number of times to advance. Default: |v:count1|.
--- - <wrap> `(boolean)` - Whether to wrap around edges. Default: `true`.
---@diagnostic disable:undefined-field

--- ## Suffix ~
---
--- The `suffix` key is used to create target mappings.
---
--- Supply empty string to disable mapping creation for that particular target.
--- To create a completely different mapping (like with |<Leader>|) use target
--- function manually.
---
--- Using `lower-suffix` and `upper-suffix` (lower and upper case suffix) for
--- a single target the following mappings are created:
--- - `[` + `upper-suffix` : go first.
--- - `[` + `lower-suffix` : go backward.
--- - `]` + `lower-suffix` : go forward.
--- - `]` + `upper-suffix` : go last.
---
--- When supplied with a non-letter, only forward/backward mappings are created.
---
--- ## Options ~
---
--- The `options` key is directly forwarded as `opts` to corresponding Lua function.
MiniBracketed.config = {
-- First-level elements are tables describing behavior of a target:
--
-- - <suffix> - single character suffix. Used after `[` / `]` in mappings.
-- For example, with `b` creates `[B`, `[b`, `]b`, `]B` mappings.
-- Supply empty string `''` to not create mappings.
--
-- - <options> - table overriding target options.

--- Undo along a tracked linear history
---
--- In a nutshell:
--- - Keys |u| and |<C-R>| (although remapped) can be used as usual, but every
--- their execution new state is recorded in this module's linear undo history.
--- - Advancing this target goes along linear undo history revealing undo states
--- **in order they actually appeared**.
--- - One big difference with built-in methods is that tracked linear history
--- can repeat undo states (not consecutively, though).
---
--- Neovim's default way of managing undo history is through branches (see
--- |undo-branches|). Basically it means that if you undo several changes and then
--- make new ones, it creates new undo branch while usually (see |'undolevels'|)
--- saving previous buffer states in another branch. While there are commands
--- to navigate by time of undo state creation (like |:earlier| and |:later|),
--- there is no intuitive way to cycle through them. Existing |g-| and |g+|
--- cycle through undo states **based on their creation time**, which often
--- gets confusing really guickly in extensively edited buffer.
---
--- This `undo()` target provides a way to cycle through linear undo history
--- **in order states actually appeared**. It does so by registering any new undo
--- states plus every time |MiniBracketed.register_undo_state()| is called. To have
--- more "out of the box" experience, |u| and |<C-R>| are remapped to call it after
--- they perform their undo/redo.
---
--- Example ~
---
--- To show more clearly the difference between advancing this target and using
--- built-in functionality, here is an example:
---
--- - Create undo history in a new buffer (|:new|):
--- - Enter `one two three` text.
--- - Delete first word with `daw` and undo the change with `u`.
--- - Delete second word with `daw` and undo the change with `u`.
--- - Delete third word with `daw` and undo the change with `u`.
---
--- - Now try one of the following (each one after performing previous steps in
--- separate new buffer):
--- - Press `u`. It goes back to empty buffer. Press `<C-R>` twice and it
--- goes to the latest change (`one two`). No way to get to other states
--- (like `two three` or `one three`) with these two keys.
---
--- - Press `g-`. It goes to an empty buffer. Press `g+` 4 times. It cycles
--- through all available undo states **in order they were created**.
---
--- - Finally, press `[u`. It goes back to `one two` - state which was
--- **previously visited** by the user. Another `[u` restores `one two three`.
--- Use `]U` to go to latest visited undo state.
