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

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 IDE will work with its regular keyboard shortcuts.

Keyboard shortcut conflicts between the Vim emulation and the IDE can be resolved via "File | Settings | Vim Emulation", "File | Settings | Keymap" and key mapping commands in your ~/.ideavimrc file.

Supported:

• Motion keys
• Deletion/changing
• Insert mode commands
• Marks
• Registers
• Undo/redo
• Visual mode commands
• Some Ex commands
• Some :set options
• Full Vim regexps for search and search/replace
• Key mappings
• Macros
• Digraphs
• Command line and search history
• Window commands
• Vim web help

Not supported (yet):

• Jump lists
• Various less used commands

• Top features and bugs

• ~/.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 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.

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 the future releases.

See also unresolved undo issues.

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.

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>

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

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

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

2. Import the project from existing sources in IntelliJ IDEA 15+ (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 6+ JDK as the Gradle JVM, leave other parameters unchanged

3. Create a new plugin run configuration using "Run | Edit Configurations | New Gradle Configuration" and run it in order to launch IntelliJ with the compiled version of the IdeaVim plugin.

   • Select your project as the Gradle project

   • Enter "runIdea" as the task to run

4. Create and run a new configuration for running tests by right-clicking on the "test" folder in the project structure and selecting "Run All Tests".

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 file using "Settings | Plugins | Install plugin from disk"
