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, Rider, Cursive, and Android Studio.

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 via "Preferences | Editor | Vim Emulation",
"Preferences | Keymap" on macOS. They can also be resolved by key-mapping
commands in your ~/.ideavimrc file.

* [Top features and bugs](https://youtrack.jetbrains.com/issues/VIM?q=%23Unresolved+sort+by%3A+votes)


Files
-----

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

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

    source ~/.vimrc

Note, that IdeaVim currently parses ~/.ideavimrc file via simple pattern matching.
See [VIM-669](https://youtrack.jetbrains.com/issue/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
    * `set surround`
    * Emulates [vim-surround](https://github.com/tpope/vim-surround)
    * Commands: `ys`, `cs`, `ds`, `S`

* multiple-cursors
    * `set multiple-cursors`
    * Emulates [vim-multiple-cursors](https://github.com/terryma/vim-multiple-cursors)
    * Commands: `<A-n>`, `<A-x>`, `<A-p>`, `g<A-n>`

* commentary
    * `set commentary`
    * Emulates [commentary.vim](https://github.com/tpope/vim-commentary)
    * Commands: `gcc`, `gc + motion`, `v_gc`


Changes to the IDE
------------------

### Undo/Redo

The IdeaVim plugin uses the undo/redo functionality of the IntelliJ Platform,
so the behavior 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](https://youtrack.jetbrains.com/issues/VIM?q=%23Unresolved+Help+topic%3A+u).

### Escape

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

See also [unresolved escape issues](https://youtrack.jetbrains.com/issues/VIM?q=%23Unresolved+Help+topic%3A+i_Esc).

### 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 or keymap pattern (E.g. `:actionlist extract`, `:actionlist <C-D`)
* `:action {name}`
    * Execute an action named `NAME`

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

    :map \r :action ReformatCode<CR>
