Use Vim Editor in RubyMine (IdeaVim)

Last modified: 09 August 2022

warning

The following is only valid when the IdeaVim plugin is installed and enabled.

The IdeaVim plugin emulates Vim in the RubyMine editor, including normal, insert, and visual modes, Command-line and Ex modes, Vim regexp and configuration, and other features.

Install the IdeaVim plugin

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), select Plugins.

  2. Find the IdeaVim plugin in the Marketplace and click Install.

  3. Restart RubyMine.

After you restart the RubyMine, Vim is enabled and the editor starts operating in the Vim mode. To disable it, deselect Tools | Vim in the main menu.

Configure shortcuts

  1. Both Vim and RubyMine are keyboard-centric. Your keymap in RubyMine may conflict with Vim's key combinations. To resolve this, select the shortcuts you prefer for different actions.

    In the Settings/Preferences dialog (Ctrl+Alt+S), select Editor | Vim Emulation.

  2. Find the shortcut and corresponding IDE action, and select how you want to handle it when you are using Vim:

    Vim Emulation settings

    • Undefined: show a popup notification that suggests to either redefine the IDE shortcut or configure the handler in Vim emulation settings.

      Shortcut notification

    • IDE: perform the IDE action associated with this shortcut.

    • Vim: handle it as a Vim shortcut.

Editing modes

With Vim, the cursor is a block when you are in the Normal mode:

Vim emulation Normal mode

To change to the Insert mode, press i, and the cursor will become a line:

Vim emulation Insert mode

In this mode you can type new code or change existing code. You can also enter other Vim modes: for example, press r for the Replace mode.

To return to the Normal mode, press Escape.

Vim configuration

Vim is configured using a vimrc file. Similarly, the VimIdea plugin uses an ideavimrc file with the same syntax. Create the configuration file in one of the following locations depending on the operating system:

%HOMEPATH%\_ideavimrc

note

The location where RubyMine looks for ideavimrc depends on the user.home JVM option, which is set to the user's home directory by default. For more information, see JVM options.

If you already have a vimrc file with your configuration, you can do one of the following:

  • Include the configuration from vimrc with the source command in your ideavimrc file:

    source ~/.vimrc

    This way you can also include other commands in your ideavimrc file, which will be applied only to your Vim in RubyMine and will not affect actual Vim configuration.

  • If you don't want to use your Vim configuration, you can rename .vimrc to .ideavimrc.

  • Create ideavimrc as a symlink to vimrc if you don't want to modify your Vim in RubyMine compared to actual Vim configuration:

    mklink _ideavimrc _vimrc
