Features

• Visualize scope with animated vertical line. It is very fast and done automatically in a non-blocking way (other operations can be performed, like moving cursor). You can customize debounce delay and animation rule.
• Customization of scope computation options can be done on global level (in MiniIndentscope.config), for a certain buffer (using vim.b.miniindentscope_config buffer variable), or within a call (using opts variable in MiniIndentscope.get_scope()).
• Customizable notion of a border: which adjacent lines with strictly lower indent are recognized as such. This is useful for a certain filetypes (for example, Python or plain text).
• Customizable way of line to be considered "border first". This is useful if you want to place cursor on function header and get scope of its body.
• There are textobjects and motions to operate on scope. Support v:count and dot-repeat (in operator pending mode).

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.indentscope')
	Stable	add({ source = 'echasnovski/mini.indentscope', 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.indentscope', version = false },
	Stable	{ 'echasnovski/mini.indentscope', 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.indentscope'
	Stable	Plug 'echasnovski/mini.indentscope', { 'branch': 'stable' }

Important: don't forget to call require('mini.indentscope').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.
{
  -- Draw options
  draw = {
    -- Delay (in ms) between event and start of drawing scope indicator
    delay = 100,

    -- Animation rule for scope's first drawing. A function which, given
    -- next and total step numbers, returns wait time (in ms). See
    -- |MiniIndentscope.gen_animation| for builtin options. To disable
    -- animation, use `require('mini.indentscope').gen_animation.none()`.
    animation = --<function: implements constant 20ms between steps>,

    -- Symbol priority. Increase to display on top of more symbols.
    priority = 2,
  },

  -- Module mappings. Use `''` (empty string) to disable one.
  mappings = {
    -- Textobjects
    object_scope = 'ii',
    object_scope_with_border = 'ai',

    -- Motions (jump to respective border line; if not present - body line)
    goto_top = '[i',
    goto_bottom = ']i',
  },

  -- Options which control scope computation
  options = {
    -- Type of scope's border: which line(s) with smaller indent to
    -- categorize as border. Can be one of: 'both', 'top', 'bottom', 'none'.
    border = 'both',

    -- Whether to use cursor column when computing reference indent.
    -- Useful to see incremental scopes with horizontal cursor movements.
    indent_at_cursor = true,

    -- Whether to first check input line to be a border of adjacent scope.
    -- Use it if you want to place cursor on function header to get scope of
    -- its body.
    try_as_border = false,
  },

  -- Which character to use for drawing scope indicator
  symbol = '╎',
