Extend and create a/i textobjects

• It enhances some builtin textobjects (like a(, a), a', and more), creates new ones (like a*, a<Space>, af, a?, and more), and allows user to create their own (like based on treesitter, and more).
• Supports dot-repeat, v:count, different search methods, consecutive application, and customization via Lua patterns or functions.
• Has builtins for brackets, quotes, function call, argument, tag, user prompt, and any punctuation/digit/whitespace character.

See more details in Features and help file.

Features

• Customizable creation of a/i textobjects using Lua patterns and functions. Supports:
  • Dot-repeat.
  • v:count.
  • Different search methods (see help for MiniAi.config).
  • Consecutive application (update selection without leaving Visual mode).
  • Aliases for multiple textobjects.
• Comprehensive builtin textobjects (see more in help for MiniAi-textobject-builtin):
  • Balanced brackets (with and without whitespace) plus alias.
  • Balanced quotes plus alias.
  • Function call.
  • Argument.
  • Tag.
  • Derived from user prompt.
  • Default for punctuation, digit, or whitespace single character.
• Motions for jumping to left/right edge of textobject.
• Set of specification generators to tweak some builtin textobjects (see help for MiniAi.gen_spec).
• Treesitter textobjects (through MiniAi.gen_spec.treesitter() helper).

Installation

This plugin can be installed as part of 'mini.nvim' library (recommended) or as a standalone Git repository.

There are two branches to install from:

• main (default, recommended) will have latest development version of plugin. All changes since last stable release should be perceived as being in beta testing phase (meaning they already passed alpha-testing and are moderately settled).
• stable will be updated only upon releases with code tested during public beta-testing phase in main branch.

Here are code snippets for some common installation methods (use only one):

With mini.deps

Github repo	Branch	Code snippet
'mini.nvim' library	Main	Follow recommended 'mini.deps' installation
	Stable
Standalone plugin	Main	add('echasnovski/mini.ai')
	Stable	add({ source = 'echasnovski/mini.ai', checkout = 'stable' })

With folke/lazy.nvim

Github repo	Branch	Code snippet
'mini.nvim' library	Main	{ 'echasnovski/mini.nvim', version = false },
	Stable	{ 'echasnovski/mini.nvim', version = '*' },
Standalone plugin	Main	{ 'echasnovski/mini.ai', version = false },
	Stable	{ 'echasnovski/mini.ai', version = '*' },

With junegunn/vim-plug

Github repo	Branch	Code snippet
'mini.nvim' library	Main	Plug 'echasnovski/mini.nvim'
	Stable	Plug 'echasnovski/mini.nvim', { 'branch': 'stable' }
Standalone plugin	Main	Plug 'echasnovski/mini.ai'
	Stable	Plug 'echasnovski/mini.ai', { 'branch': 'stable' }

Important: don't forget to call require('mini.ai').setup() to enable its functionality.

Note: if you are on Windows, there might be problems with too long file paths (like error: unable to create file <some file name>: Filename too long). Try doing one of the following:

• Enable corresponding git global config value: git config --system core.longpaths true. Then try to reinstall.
• Install plugin in other place with shorter path.

Default config

-- No need to copy this inside `setup()`. Will be used automatically.
{
  -- Table with textobject id as fields, textobject specification as values.
  -- Also use this to disable builtin textobjects. See |MiniAi.config|.
  custom_textobjects = nil,

  -- Module mappings. Use `''` (empty string) to disable one.
  mappings = {
    -- Main textobject prefixes
    around = 'a',
    inside = 'i',

    -- Next/last variants
    around_next = 'an',
    inside_next = 'in',
    around_last = 'al',
    inside_last = 'il',

    -- Move cursor to corresponding edge of `a` textobject
    goto_left = 'g[',
    goto_right = 'g]',
  },

  -- Number of lines within which textobject is searched
  n_lines = 50,

  -- How to search for object (first inside current line, then inside
  -- neighborhood). One of 'cover', 'cover_or_next', 'cover_or_prev',
  -- 'cover_or_nearest', 'next', 'previous', 'nearest'.
  search_method = 'cover_or_next',

  -- Whether to disable showing non-error feedback
  -- This also affects (purely informational) helper messages shown after
  -- idle time if user input is required.
  silent = false,
