InstantRename is a small Neovim plugin that automatically replaces the :s command with a global substitute command in command-line mode.

Using lazy.nvim:

 {
  'mei28/instant_rename.nvim',
  event = { 'ModeChanged', 'CmdlineChanged' }, -- for lazy loading
  config = function()
    require('instant_rename')
  end
}

• Simply type :s in command-line mode, and it will be automatically expanded to :%s///g.
