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

Important: don't forget to call require('mini.operators').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.

Default config

-- No need to copy this inside `setup()`. Will be used automatically.
{
  -- Each entry configures one operator.
  -- `prefix` defines keys mapped during `setup()`: in Normal mode
  -- to operate on textobject and line, in Visual - on selection.

  -- Evaluate text and replace with output
  evaluate = {
    prefix = 'g=',

    -- Function which does the evaluation
    func = nil,
  },

  -- Exchange text regions
  exchange = {
    prefix = 'gx',

    -- Whether to reindent new text to match previous indent
    reindent_linewise = true,
  },

  -- Multiply (duplicate) text
  multiply = {
    prefix = 'gm',

    -- Function which can modify text before multiplying
    func = nil,
  },

  -- Replace text with register
  replace = {
    prefix = 'gr',

    -- Whether to reindent new text to match previous indent
    reindent_linewise = true,
  },

  -- Sort text
  sort = {
    prefix = 'gs',

    -- Function which does the sort
    func = nil,
  }
}
