--- *mini.basics* Common configuration presets
--- *MiniBasics*
---
--- MIT License Copyright (c) 2023 Evgeni Chasnovski
---
--- ==============================================================================
---
--- Install, create 'init.lua', add `require('mini.basics').setup()` and you
--- are good to go.
---
--- Features:
--- - Presets for common options. It will only change option if it wasn't
--- manually set before. See more in |MiniBasics.config.options|.
---
--- - Presets for common mappings. It will only add a mapping if it wasn't
--- manually created before. See more in |MiniBasics.config.mappings|.
---
--- - Presets for common autocommands. See more in |MiniBasics.config.autocommands|.
---
--- - Reverse compatibility is a high priority. Any decision to change already
--- present behavior will be made with great care.
---
--- Notes:
--- - Main goal of this module is to provide a relatively easier way for
--- new-ish Neovim users to have better "works out of the box" experience
--- while having documented relevant options/mappings/autocommands to study.
--- It is based partially on survey among Neovim users and partially is
--- coming from personal preferences.
---
--- However, more seasoned users almost surely will find something useful.
---
--- Still, it is recommended to read about used options/mappings/autocommands
--- and decide if they are needed. The main way to do that is by reading
--- Neovim's help pages (linked in help file) and this module's source code
--- (thoroughly documented for easier comprehension).
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.basics').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniBasics`
--- which you can use for scripting or manually (with `:lua MiniBasics.*`).
---
--- See |MiniBasics.config| for available config settings.
---
--- To stop module from showing non-error feedback, set `config.silent = true`.
---
--- # Comparisons ~
---
--- - 'tpope/vim-sensible':
--- - Most of 'tpope/vim-sensible' is already incorporated as default
--- options in Neovim (see |nvim-default|). This module has a much
--- broader effect.
--- - 'tpope/vim-unimpaired':
--- - The 'tpope/vim-unimpaired' has mapping for toggling options with `yo`
--- prefix. This module implements similar functionality with `\` prefix
--- (see |MiniBasics.config.mappings|).
---@diagnostic disable:undefined-field
-- To study source behind presets, search for:
-- - `-- Options ---` for `config.options`.
-- - `-- Mappings ---` for `config.mappings`.
-- - `-- Autocommands ---` for `config.autocommands`.
-- Module definition ==========================================================
local MiniBasics = {}
local H = {}
--- Module setup
---
---@param config table|nil Module config table. See |MiniBasics.config|.
---
---@usage `require('mini.basics').setup({})` (replace `{}` with your `config` table)
MiniBasics.setup = function(config)
-- Export module
_G.MiniBasics = MiniBasics
-- Setup config
config = H.setup_config(config)
-- Apply config
H.apply_config(config)
end
--- Module config
---
--- Default values:
---@eval return MiniDoc.afterlines_to_code(MiniDoc.current.eval_section)
---@text *MiniBasics.config.options*
--- # Options ~
---
--- Usage example: >
--- require('mini.basics').setup({
--- options = {
--- basic = true,
--- extra_ui = true,
--- win_borders = 'double',
--- }
--- })
---
--- ## options.basic ~
---
--- The `config.options.basic` sets certain options to values which are quite
--- commonly used (judging by study of available Neovim pre-configurations,
--- public dotfiles, and surveys).
--- Any option is changed only if it was not set manually beforehand.
--- For exact changes, please see source code ('lua/mini/basics.lua').
---
--- Here is the list of affected options (put cursor on it and press |CTRL-]|):
--- - General:
--- - Sets |<Leader>| key to |<Space>|. Be sure to make all Leader mappings
--- after this (otherwise they are made with default <Leader>).
--- - Runs `:filetype plugin indent on` (see |:filetype-overview|)
--- - |backup|
--- - |mouse|
--- - |undofile|
--- - |writebackup|
--- - Appearance
--- - |breakindent|
--- - |cursorline|
--- - |fillchars|
--- - |linebreak|
--- - |number|
--- - |ruler|
--- - |showmode|
--- - |signcolumn|
--- - |shortmess|
--- - |splitbelow|
--- - |splitkeep| (on Neovim>=0.9)
--- - |splitright|
--- - |termguicolors|
--- - |wrap|
--- - Editing
--- - |completeopt|
--- - |formatoptions|
--- - |ignorecase|
--- - |incsearch|
--- - |infercase|
--- - |smartcase|
--- - |smartindent|
--- - |virtualedit|
---
--- ## options.extra_ui ~
---
--- The `config.options.extra_ui` sets certain options for visual appearance
--- which might not be aligned with common preferences, but still worth trying.
--- Any option is changed only if it was not set manually beforehand.
--- For exact changes, please see source code ('lua/mini/basics.lua').
---
--- List of affected options:
--- - |list|
--- - |listchars|
--- - |pumblend|
--- - |pumheight|
--- - |winblend|
--- - Runs `:syntax on` (see |:syntax-on|)
---
--- ## options.win_borders
---
--- The `config.options.win_borders` updates |fillchars| to have a consistent set of
--- characters for window border (`vert`, `horiz`, etc.).
---
--- Available values:
--- - `'bold'` - bold lines.
--- - `'dot'` - dot in every cell.
--- - `'double'` - double line.
--- - `'single'` - single line.
--- - `'solid'` - no symbol, only background.
---
--- *MiniBasics.config.mappings*
--- # Mappings ~
---
--- Usage example: >
--- require('mini.basics').setup({
--- mappings = {
--- basic = true,
--- option_toggle_prefix = [[\]],
--- windows = true,
--- move_with_alt = true,
--- }
--- })
---
--- If you don't want only some mappings to be made at all, use |vim.keymap.del()|
--- after calling |MiniMisc.setup()|. For example, to delete `<C-w>` mapping in
--- |Terminal-mode| (as it conflicts with `<C-w>` usage in terminal emulators)
--- use this code: >
---
--- vim.keymap.del('t', '<C-w>').
---
--- ## mappings.basic ~
---
--- The `config.mappings.basic` creates mappings for certain commonly mapped actions
--- (judging by study of available Neovim pre-configurations and public dotfiles).
---
--- Some of the mappings override built-in ones to either improve their
--- behavior or override its default not very useful action.
--- It will only add a mapping if it wasn't manually created before.
---
--- Here is a table with created mappings (see |[count]| for its meaning;): >
---
--- |Keys | Modes | Description |
--- |-------|-----------------|-----------------------------------------------|
--- | j | Normal, Visual | Move down by visible lines with no [count] |
--- | k | Normal, Visual | Move up by visible lines with no [count] |
--- | go | Normal | Add [count] empty lines after cursor |
--- | gO | Normal | Add [count] empty lines before cursor |
--- | gy | Normal, Visual | Copy to system clipboard |
--- | gp | Normal, Visual | Paste from system clipboard |
--- | gV | Normal | Visually select latest changed or yanked text |
--- | g/ | Visual | Search inside current visual selection |
--- | * | Visual | Search forward for current visual selection |
--- | # | Visual | Search backward for current visual selection |
--- | <C-s> | Normal, Visual, | Save and go to Normal mode |
--- | | Insert | |
--- | <C-z> | Normal, Insert | Correct latest misspelled word |
--- <
---
--- ## mappings.option_toggle_prefix ~
---
--- The `config.mappings.option_toggle_prefix` defines a prefix used for
--- creating mappings that toggle common options. The result mappings will be
--- `<prefix> + <suffix>`. For example, with default value, `\w` will toggle |wrap|.
---
--- Other viable choices for prefix are
--- - `,` (as a mnemonic for several values to toggle).
--- - `|` (as a same mnemonic).
--- - `yo` (used in 'tpope/vim-unimpaired')
--- - Something with |<Leader>| key, like `<Leader>t` (`t` for "toggle"). Note:
--- if your prefix contains `<Leader>` key, make sure to set it before
--- calling |MiniBasics.setup()| (as is done with default `basic` field of
--- |MiniBasics.config.options|).
---
--- After toggling, there will be a feedback about the current option value if
--- prior to `require('mini.basics').setup()` module wasn't silenced (see
--- "Silencing" section in |mini.basics|).
---
--- It will only add a mapping if it wasn't manually created before.
---
--- Here is a list of suffixes for created toggling mappings (all in Normal mode):
---
--- - `b` - |'background'|.
--- - `c` - |'cursorline'|.
--- - `C` - |'cursorcolumn'|.
--- - `d` - diagnostic (via |vim.diagnostic.enable()| and |vim.diagnostic.disable()|).
--- - `h` - |'hlsearch'| (or |v:hlsearch| to be precise).
--- - `i` - |'ignorecase'|.
--- - `l` - |'list'|.
--- - `n` - |'number'|.
--- - `r` - |'relativenumber'|.
--- - `s` - |'spell'|.
--- - `w` - |'wrap'|.
---
--- ## mappings.windows ~
---
--- The `config.mappings.windows` creates mappings for easiere window manipulation.
---
--- It will only add a mapping if it wasn't manually created before.
---
--- Here is a list with created Normal mode mappings (all mappings respect |[count]|):
--- - Window navigation:
--- - `<C-h>` - focus on left window (see |CTRL-W_H|).
--- - `<C-j>` - focus on below window (see |CTRL-W_J|).
--- - `<C-k>` - focus on above window (see |CTRL-W_K|).
--- - `<C-l>` - focus on right window (see |CTRL-W_L|).
--- - Window resize (all use arrow keys; variants of |resize|; all respect |[count]|):
--- - `<C-left>` - decrease window width.
--- - `<C-down>` - decrease window height.
--- - `<C-up>` - increase window height.
--- - `<C-right>` - increase window width.
---
--- It also creates a `<C-w>` mapping in |Terminal-mode| for easier window
--- navigation inside builtin |terminal-emulator|. Tip: use `<C-w><Esc>` for
--- easier Terminal mode exit than |CTRL-\_CTRL-N|.
---
--- ## mappings.move_with_alt
---
--- The `config.mappings.move_with_alt` creates mappings for a more consistent
--- cursor move in Insert, Command, and Terminal modes. For example, it proves
--- useful in combination of autopair plugin (like |MiniPairs|) to move right
--- outside of inserted pairs (no matter what the pair is).
---
--- It will only add a mapping if it wasn't manually created before.
---
--- Here is a list of created mappings (`<M-x>` means `Alt`/`Meta` plus `x`):
--- - `<M-h>` - move cursor left. Modes: Insert, Terminal, Command.
--- - `<M-h>` - move cursor down. Modes: Insert, Terminal.
--- - `<M-h>` - move cursor up. Modes: Insert, Terminal.
--- - `<M-h>` - move cursor right. Modes: Insert, Terminal, Command.
---
--- *MiniBasics.config.autocommands*
--- # Autocommands ~
---
--- Usage example: >
--- require('mini.basics').setup({
--- autocommands = {
--- basic = true,
--- relnum_in_visual_mode = true,
--- }
--- })
---
--- ## autocommands.basic ~
---
--- The `config.autocommands.basic` creates some common autocommands:
---
--- - Starts insert mode when opening terminal (see |startinsert| and |TermOpen|).
--- - Highlights yanked text for a brief period of time (see
--- |vim.highlight.on_yank()| and |TextYankPost|).
---
--- ## autocommands.relnum_in_visual_mode ~
---
--- The `config.autocommands.relnum_in_visual_mode` creates autocommands that
--- enable |relativenumber| in linewise and blockwise Visual modes and disable
--- otherwise. See |ModeChanged|.
MiniBasics.config = {
-- Options. Set to `false` to disable.
