--- *mini.move* Move any selection in any direction

--- *MiniMove*

---

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

---

--- Features:

--- - Works in two modes:

--- - Visual mode. Select text (charwise with |v|, linewise with |V|, and

--- blockwise with |CTRL-V|) and press customizable mapping to move in

--- all four directions (left, right, down, up). It keeps Visual mode.

--- - Normal mode. Press customizable mapping to move current line in all

--- four directions (left, right, down, up).

--- - Special handling of linewise movement:

--- - Vertical movement gets reindented with |=|.

--- - Horizontal movement is improved indent/dedent with |>| / |<|.

--- - Cursor moves along with selection.

---

--- - Provides both mappings and Lua functions for motions. See

--- |MiniMove.move_selection()| and |MiniMove.move_line()|.

---

--- - Respects |v:count|. Movement mappings can be preceded by a number which

--- multiplies command effect.

---

--- - All consecutive moves (regardless of direction) can be undone by a single |u|.

---

--- - Respects preferred column for vertical movement. It will vertically move

--- selection as how cursor is moving (not strictly vertically if target

--- column is not present in target line).

---

--- Notes:

--- - Doesn't allow moving selection outside of current lines (by design).

---

--- # Setup ~

---

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

--- `{}` with your `config` table). It will create global Lua table `MiniMove`

--- which you can use for scripting or manually (with `:lua MiniMove.*`).

---

--- See |MiniMove.config| for available config settings.

---

--- You can override runtime config settings (but not `config.mappings`) locally

--- to buffer inside `vim.b.minimove_config` which should have same structure

--- as `MiniMove.config`. See |mini.nvim-buffer-local-config| for more details.

---

--- # Comparisons ~

---

--- - 'matze/vim-move':

--- - Doesn't support vertical movement of charwise and blockwise selections.

--- While 'mini.move' does.

--- - Doesn't support horizontal movement of current line in favor of

--- horizontal movement of current character. While 'mini.move' supports

--- horizontal movement of current line and doesn't support such movement

--- of current character.

--- - Has extra functionality for certain moves (like move by half page).

--- While 'mini.move' does not (by design).

--- - 'booperlv/nvim-gomove':

--- - Doesn't support movement in charwise visual selection.

--- While 'mini.move' does.

--- - Has extra functionality beyond moving text, like duplication.

--- While 'mini.move' concentrates only on moving functionality.

---

--- # Disabling ~

---

--- To disable, set `vim.g.minimove_disable` (globally) or `vim.b.minimove_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.

---@alias __move_direction string One of "left", "down", "up", "right".

---@alias __move_opts table|nil Options. Same structure as `options` in |MiniMove.config|

--- (with its values as defaults) plus these allowed extra fields:

--- - <n_times> (number) - number of times to try to make a move.

--- Default: |v:count1|.

---@diagnostic disable:undefined-field

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

local H = {}

---@param config table|nil Module config table. See |MiniMove.config|.
