Features

  • Commenting in Normal mode respects v:count and is dot-repeatable.
  • Comment structure is inferred from 'commentstring': either from current buffer or from locally active tree-sitter language (only on Neovim>=0.9). It can be customized via options.custom_commentstring.
  • Handles both tab and space indenting (but not when they are mixed).
  • Allows custom hooks before and after successful commenting.
  • Configurable options for some nuanced behavior.

Notes:

  • To use tree-sitter aware commenting, global value of 'commentstring' should be '' (empty string). This is the default value in Neovim>=0.9, so make sure to not set it manually.

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 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.comment', version = false },
Stable { 'echasnovski/mini.comment', version = '*' },
With wbthomason/packer.nvim
Github repo Branch Code snippet
'mini.nvim' library Main use 'echasnovski/mini.nvim'
Stable use { 'echasnovski/mini.nvim', branch = 'stable' }
Standalone plugin Main use 'echasnovski/mini.comment'
Stable use { 'echasnovski/mini.comment', branch = 'stable' }
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.comment'
Stable Plug 'echasnovski/mini.comment', { 'branch': 'stable' }

Important: don't forget to call require('mini.comment').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.
{
  -- Options which control module behavior
  options = {
    -- Function to compute custom 'commentstring' (optional)
    custom_commentstring = nil,

    -- Whether to ignore blank lines
    ignore_blank_line = false,

    -- Whether to recognize as comment only lines without indent
    start_of_line = false,

    -- Whether to ensure single space pad for comment parts
    pad_comment_parts = true,
  },

  -- Module mappings. Use `''` (empty string) to disable one.
  mappings = {
    -- Toggle comment (like `gcip` - comment inner paragraph) for both
    -- Normal and Visual modes
    comment = 'gc',

    -- Toggle comment on current line
    comment_line = 'gcc',

    -- Define 'comment' textobject (like `dgc` - delete whole comment block)
    textobject = 'gc',
  },

  -- Hook functions to be executed at certain stage of commenting
  hooks = {
    -- Before successful commenting. Does nothing by default.
    pre = function() end,
    -- After successful commenting. Does nothing by default.
    post = function() end,
  },
}
