Vim emulation plug-in for IDEs based on the IntelliJ platform.

IdeaVim

Build

Tests

IdeaVim is a Vim emulation plugin for IDEs based on the IntelliJ platform. IdeaVim can be used with IntelliJ IDEA, PyCharm, CLion, PhpStorm, WebStorm, RubyMine, AppCode, DataGrip, GoLand, Cursive, and Android Studio.

• Plugin homepage
• Changelog
• Bug tracker
• Continuous integration builds
• @IdeaVim in Twitter

Installation

Use the IDE's plugin manager to install the latest version of the plugin. Start the IDE normally and enable the Vim emulation using "Tools | Vim Emulator" menu item. At this point you must use Vim keystrokes in all editors.

If you wish to disable the plugin, select the "Tools | Vim Emulator" menu so it is unchecked. At this point your IDE will work with its regular keyboard shortcuts.

Keyboard shortcut conflicts between the Vim emulation and the IDE can be resolved via "File | Settings | Editor | Vim Emulation", "File | Settings | Keymap" on Linux & Windows, and by "Preferences | Editor | Vim Emulation", "Preferences | Keymap" on macOS. They can also be resolved by key mapping commands in your ~/.ideavimrc file.

It is important to distinguish EAP from traditional pre-release software. Please note that the quality of EAP versions may at times be way below even usual beta standards.

Files

• ~/.ideavimrc
  • Your IdeaVim-specific Vim initialization commands

You can read your ~/.vimrc file from ~/.ideavimrc using this command:

source ~/.vimrc

Note, that IdeaVim currently parses ~/.ideavimrc file via simple pattern matching, see VIM-669 for proper parsing of VimL files.

Also note that if you have overridden the user.home JVM option, this will affect where IdeaVim looks for your .ideavimrc file. For example, if you have -Duser.home=/my/alternate/home then IdeaVim will source /my/alternate/home/.ideavimrc instead of ~/.ideavimrc.

Emulated Vim Plugins

IdeaVim extensions emulate some plugins of the original Vim. In order to use IdeaVim extensions, you have to enable them via this command in your ~/.ideavimrc:

set <extension-name>

Available extensions:

• surround
  • Emulates vim-surround
  • Commands: ys, cs, ds, S
• multiple-cursors
  • Emulates vim-multiple-cursors
  • Commands: <A-n>, <A-x>, <A-p>, g<A-n>

Changes to the IDE

Undo/Redo

The IdeaVim plugin uses the undo/redo functionality of the IntelliJ platform, so the behaviour of the u and <C-R> commands may differ from the original Vim. Vim compatibility of undo/redo may be improved in future releases.

See also unresolved undo issues.

Escape

Using <Esc> in dialog windows remains problematic. For most dialog windows the Vim emulator is put into the insert mode with <Esc> not working. You should use <C-c> or <C-[> instead. In some dialog windows the normal mode is on by default. The usage of the Vim emulator in dialog windows is an area for improvements.

See also unresolved escape issues.

Executing IDE Actions

IdeaVim adds two commands for listing and executing arbitrary IDE actions as Ex commands or via :map command mappings:

• :actionlist [pattern]
  • Find IDE actions by name pattern
• :action {name}
  • Execute an action named NAME

For example, here \r is mapped to the Reformat Code action:

:map \r :action ReformatCode<CR>

Contributing

Where to Start

In order to contribute to IdeaVim you should have some understanding of Java.

See also these docs on the IntelliJ API:

• IntelliJ architectural overview
• IntelliJ plugin development resources

You can start by picking relatively simple tasks that are tagged with #patch_welcome in the issue tracker.

Development Environment

1. Fork IdeaVim on GitHub and clone the repository on your local machine.

2. Import the project from existing sources in IntelliJ IDEA 2018.1 or newer (Community or Ultimate) using "File | New | Project from Existing Sources..." or "Import Project" from the start window.

   • In the project wizard select "Import project from external model | Gradle"

   • Select your Java 8+ JDK as the Gradle JVM, leave other parameters unchanged

3. Run your IdeaVim plugin within IntelliJ via a Gradle task

   • Select "View | Tool Windows | Gradle" tool window

   • Launch "ideavim | intellij | runIde" from the tool window

4. Run IdeaVim tests via a Gradle task

   • Select "View | Tool Windows | Gradle" tool window

   • Launch "ideavim | verification | test" from the tool window

5. Build the plugin distribution by running ./gradlew clean buildPlugin in the terminal in your project root.

   • The resulting distribution file is build/distributions/IdeaVim-VERSION.zip

   • You can install this file using "Settings | Plugins | Install plugin from disk"
