Features

• Show and manage special floating window displaying automatically updated overview of current buffer text. Window takes up whole height of Neovim instance and is fixed to a left/right side. Map content is computed by taking all current lines, converting it to binary whitespace/non-whitespace mask, rescaling to appropriate dimensions, and converting back to strings consisting from special encoding symbols. All this is done very fast and asynchronously.

  See :h MiniMap.open(), :h MiniMap.refresh(), :h MiniMap.close(), :h MiniMap.toggle(), :h MiniMap.toggle_side().

  For a general overview and tips, see :h mini.map-usage.

• Show scrollbar next to map content. It represents current line and view (top and bottom visible lines). Can be the only thing shown, making map window a "pure scrollbar".

• Highlight map lines representing certain data in current buffer. This is done via extensible set of callables, called integrations. There are pre-built generators for common integrations:

  • Builtin search.
  • Builtin diagnostic.
  • Git line status. For more details see :h MiniMap.gen_integration.

• Focus on map window to quickly browse current (source) buffer. Moving inside map window updates cursor position in source window enabling fast and targeted buffer exploration. To focus back, hit <CR> to accept current explored position or <Esc> to go back to original position. See :h MiniMap.toggle_focus().

• Customizable:

  • Encoding symbols used to display binary information of different resolution (default is 3x2). There are pre-built generators for different basic character families and resolutions. See :h MiniMap.gen_encode_symbols.
  • Scrollbar symbols, separate for line and view. Can have any width (even zero, which virtually disables scrollbar).
  • Integrations producing map line highlights.
  • Window options: side (left/right), width, 'winblend', and more.

Installation

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):

• Using wbthomason/packer.nvim:

Branch	Code snippet
Main	use 'echasnovski/mini.nvim'
Stable	use { 'echasnovski/mini.nvim', branch = 'stable' }

• Using junegunn/vim-plug:

Branch	Code snippet
Main	Plug 'echasnovski/mini.nvim'
Stable	Plug 'echasnovski/mini.nvim', { 'branch': 'stable' }

Important: don't forget to call require('mini.map').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.
{
  -- Highlight integrations (none by default)
  integrations = nil,

  -- Symbols used to display data
  symbols = {
    -- Encode symbols. See `:h MiniMap.config` for specification and
    -- `:h MiniMap.gen_encode_symbols` for pre-built ones.
    -- Default: solid blocks with 3x2 resolution.
    encode = nil,

    -- Scrollbar parts for view and line. Use empty string to disable any.
    scroll_line = '█',
    scroll_view = '┃',
  },

  -- Window options
  window = {
    -- Whether window is focusable in normal way (with `wincmd` or mouse)
    focusable = false,

    -- Side to stick ('left' or 'right')
    side = 'right',

    -- Whether to show count of multiple integration highlights
    show_integration_count = true,

    -- Total width
    width = 10,

    -- Value of 'winblend' option
    winblend = 25,
  },
}
