*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`

Diagnostic...................... `[D` `[d` `]d` `]D` .... |MiniBracketed.diagnostic()|
File on disk.................... `[F` `[f` `]f` `]F` .... |MiniBracketed.file()|

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.

*MiniBracketed.setup()*
`MiniBracketed.setup`({config})
Module setup
Parameters ~
{config} `(table|nil)` Module config table. See |MiniBracketed.config|.
Usage ~
>lua
require('mini.bracketed').setup() -- use default config
-- OR
require('mini.bracketed').setup({}) -- replace {} with your config table
<
------------------------------------------------------------------------------
*MiniBracketed.config*
`MiniBracketed.config`
Module config
Default values:
>lua
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.
--
-- See `:h MiniBracketed.config` for more info.
buffer = { suffix = 'b', options = {} },
comment = { suffix = 'c', options = {} },
conflict = { suffix = 'x', options = {} },
diagnostic = { suffix = 'd', options = {} },
file = { suffix = 'f', options = {} },
indent = { suffix = 'i', options = {} },
jump = { suffix = 'j', options = {} },

treesitter = { suffix = 't', options = {} },
undo = { suffix = 'u', options = {} },
window = { suffix = 'w', options = {} },
yank = { suffix = 'y', options = {} },
}
<
Options ~
Each entry configures target with the same name and can have data configuring
mapping suffix and target options.
Example of configuration: >lua
require('mini.bracketed').setup({
-- Map [N, [n, ]n, ]N for conflict marker like in 'tpope/vim-unimpaired'
conflict = { suffix = 'n' },
-- Make diagnostic advance only by errors
diagnostic = { options = { severity = vim.diagnostic.severity.ERROR } },
-- Disable creation of mappings for `indent` target (for example,
-- in favor of ones from |mini.indentscope|)
indent = { suffix = '' },
-- Disable mappings for `window` target in favor of custom ones
window = { suffix = '' },
})
-- Create custom `window` mappings
local map = vim.keymap.set
map('n', '<Leader>wH', "<Cmd>lua MiniBracketed.window('first')<CR>")
map('n', '<Leader>wh', "<Cmd>lua MiniBracketed.window('backward')<CR>")
map('n', '<Leader>wl', "<Cmd>lua MiniBracketed.window('forward')<CR>")
map('n', '<Leader>wL', "<Cmd>lua MiniBracketed.window('last')<CR>")
<
## 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.

Go to next/previous line with different indent (see |indent()|).
Can be used to go to lines with smaller, bigger, or different indent.
Notes:
- Directions "first" and "last" work differently from most other targets
for performance reasons. They are essentially "backward" and "forward"
with very big `n_times` option.
- For similar reasons, `wrap` is not supported.

*MiniBracketed.jump()*
`MiniBracketed.jump`({direction}, {opts})
Jump inside current buffer
Go to next/previous jump from |jumplist| which is inside current buffer.
Notes:
- There are no Visual mode mappings due to implementation problems.

|:lfirst|, |:lprevious|, |:lnext|, and |:llast| but with support of
wrapping around edges and |[count]| for "first"/"last" direction.
Direction "forward" increases location number, "backward" - decreases.
Parameters ~

`MiniBracketed.oldfile`({direction}, {opts})
Old files from previous and current sessions
Go to older/newer readable file either from previous session (see |v:oldfiles|)
or the current one (updated automatically after |MiniBracketed.setup()| call).
Direction "forward" goes to more recent files, "backward" - to older.
Notes:
- In current session it tracks only normal buffers (see |'buftype'|) for
some readable file.
- No new file is tracked when advancing this target. Only after buffer
change is done not through this target (like with |MiniBracketed.buffer()|),
it updates recency of last advanced and new buffers.

or |vim.treesitter.get_node()| (present in Neovim>=0.9) along with loaded
tree-sitter parser in current buffer.
- Directions "first" and "last" work differently from most other targets
for performance reasons. They are essentially "backward" and "forward"
with very big `n_times` option.
- For similar reasons, `wrap` is not supported.
Direction "forward" moves cursor forward to node's end, "backward" - backward
to node's start.

Default: `false`.
------------------------------------------------------------------------------
*MiniBracketed.undo()*
`MiniBracketed.undo`({direction}, {opts})
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.
Parameters ~
{direction} `(string)` One of "first", "backward", "forward", "last".
{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`.
------------------------------------------------------------------------------
*MiniBracketed.register_undo_state()*
`MiniBracketed.register_undo_state`()
Register state for undo target
Use this function to add current undo state to this module's linear undo
history. It is used in |MiniBracketed.setup()| to remap |u| and |<C-R>| keys to add
their new state to linear undo history.
------------------------------------------------------------------------------
*MiniBracketed.window()*
`MiniBracketed.window`({direction}, {opts})
Normal window
Go to next/previous normal window. Order by their number (see |winnr()|).
Direction "forward" increases window number, "backward" - decreases.
Only normal (non-floating) windows are used.
Parameters ~
{direction} `(string)` One of "first", "backward", "forward", "last".
{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`.
------------------------------------------------------------------------------
*MiniBracketed.yank()*
`MiniBracketed.yank`({direction}, {opts})
Replace "latest put region" with yank history entry
After |MiniBracketed.setup()| is called, on every yank/delete/change operation
(technically, every trigger of |TextYankPost| event) the object of operation
is added to yank history. Advancing this target will replace the region of
latest put operation with entry from yank history.
By default works best if called **right after** text paste (like with |p| or |P|).
To better detect "latest put region", use |MiniBracketed.register_put_region()|
as described later.
Direction "forward" goes to newer yank history entry, "backward" - to older.
Example ~
- Type `one two three`.
- Yank each word with `yiw`.
- Create new line and press `p`. This should paste `three`.
- Type `[y`. This should replace latest `three` with `two`.
Latest put region ~
"Latest put region" is (in order of decreasing priority):
- The one from latest advance of this target.
- The one registered by user with |MiniBracketed.register_put_region()|.
- The one taken from |`[| and |`]| marks.
For users there are these approaches to manage which region will be used:
- Do nothing. In this case region between `[` / `]` marks will always be used
for first `yank` advance.
Although doable, this has several drawbacks: it will use latest yanked or
changed region or the entire buffer if marks are not set.
If remember to advance this target only after recent put operation, this
should work as expected.
- Remap common put operations to use |MiniBracketed.register_put_region()|.
After that, only regions from mapped put operations will be used for first
advance. Example of custom mappings (note use of |:map-expression|): >lua
local put_keys = { 'p', 'P' }
for _, lhs in ipairs(put_keys) do
local rhs = 'v:lua.MiniBracketed.register_put_region("' .. lhs .. '")'
vim.keymap.set({ 'n', 'x' }, lhs, rhs, { expr = true })
end
<
Parameters ~
{direction} `(string)` One of "first", "backward", "forward", "last".
{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`.
- <operators> `(table)` - array of operator names ("c", "d", or "y") for
which yank entry should be used to advance. For example, use `{ "y" }`
to advance only by entries actually resulted from yank operation with |y|.
Default: `{ 'c', 'd', 'y' }`.
------------------------------------------------------------------------------
*MiniBracketed.register_put_region()*
`MiniBracketed.register_put_region`({put_key})
Register "latest put region"
This function should be called after put register becomes relevant
(|v:register| is appropriately set) but before put operation takes place
(|`[| and |`]| marks become relevant).
Designed to be used in a user-facing expression mapping (see |:map-expression|).
For mapping examples see |MiniBracketed.yank()|.
Parameters ~
{put_key} `(string)` Put keys to be remapped.
Return ~
`(string)` Returns `put_key` for a better usage inside expression mappings.
------------------------------------------------------------------------------
*MiniBracketed.advance()*
`MiniBracketed.advance`({iterator}, {direction}, {opts})
Advance iterator
This is the main function which performs any forward/backward/first/last
advance in this module. Its basic idea is to take iterator (object containing
information about current state and how to go to next/previous one) and go
in certain direction until needed/allowed.
Notes:
- Directions "first" and "last" are convenience wrappers for "forward" and
"backward" with pre-setting initial state to `start_edge` and `end_edge`.
- Iterators `next()` and `prev()` methods should be able to handle `nil` as input.
- This function only returns new state and doesn't modify `iterator.state`.
Parameters ~
{iterator} `(table)` Table:
- Methods:
- <next> - given state, return state in forward direction (no wrap).
- <prev> - given state, return state in backward direction (no wrap).
- Fields:
- <state> - object describing current state.
- <start_edge> (optional) - object with `forward(start_edge)` describing
first state. If `nil`, can't wrap forward or use direction "first".
- <end_edge> (optional) - object with `backward(end_edge)` describing
last state. If `nil`, can't wrap backward or use direction "last".
{direction} `(string)` Direction. One of "first", "backward", "forward", "last".
{opts} `(table|nil)` Options with the following keys:
- <n_times> `(number)` - number of times to go in input direction.
Default: `v:count1`.
- <wrap> `(boolean)` - whether to wrap around edges when `next()` or
`prev()` return `nil`. Default: `true`.
Return ~
`(any)` Result state. If `nil`, could not reach any valid result state.
