Android Studio and other IntelliJ platform based IDEs.
Setup
------------
- IdeaVim can be installed via `Settings | Plugins`.
See the [detailed instructions](https://www.jetbrains.com/help/idea/managing-plugins.html#).
- Use `Tools | Vim Emulator` to enable or disable emulation.
- Use the `~/.ideavimrc` file as an analog of `~/.vimrc` ([learn more](#Files)). The XDG standard is supported, as well.
- Shortcut conflicts can be resolved by using:
- On Linux & Windows: `File | Settings | Editor | Vim Emulation` & `File | Settings | Keymap`,
- On macOS: `Preferences | Editor | Vim Emulation` & `Preferences | Keymap`,
- Regular Vim mappings in the `~/.ideavimrc` file.

</details>
You can read your `~/.vimrc` file from `~/.ideavimrc` with this command:
source ~/.vimrc
Please note that IdeaVim currently parses `~/.ideavimrc` & `~/.vimrc` files 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`.
Alternatively, you can set up initialization commands using [XDG](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html) standard.
Put your settings to `$XDG_CONFIG_HOME/ideavim/ideavimrc` file.
Emulated Vim Plugins
--------------------
See [doc/emulated-plugins.md](doc/emulated-plugins.md)
Changes to the IDE
------------------
### 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`
In addition to `:actionlist` command, IdeaVim provides `IdeaVim: track action Ids` option to
extract the ids of executed command. This option can be found in "Search everywhere" (double `shift`). **[To Be Released]**
<details>
<summary><strong>"Track aciton Ids" Details</strong> (click to see)</summary>
<img src="resources/readme/track_action_id.gif" alt="track actioin ids"/>
</details>
For the mappings you can use a special `<Action>` keyword. Use `<Action>(*action_id*)` to map keys to some action. Don't
forget the parentheses. This keyword works for insert mode as well. **[To Be Released]**
Examples:
```vim
" Map \r to the Reformat Code action
:map \r :action ReformatCode<CR>
" or
:map \r <Action>(ReformatCode) " [To Be Released]
" Map <leader>d to start debug
:map <leader>d :action Debug<CR>
" or
:map <leader>d <Action>(Debug) " [To Be Released]
" Map \b to toggle the breakpoint on the current line
:map \b :action ToggleLineBreakpoint<CR>
" or
:map \b <Action>(ToggleLineBreakpoint) " [To Be Released]
```
### 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.

IdeaVim tips and tricks
-------
- Use the power of IJ and Vim:
- `set ideajoin` to enable join via the IDE. See the [examples](https://jb.gg/f9zji9).
- Make sure `ideaput` is enabled for `clipboard` to enable native IJ insertion in Vim.
- Sync IJ bookmarks and Vim marks: `set ideamarks`
- Check out more [ex commands](doc/set-commands.md).
- Use your vim settings with IdeaVim. Put `source ~/.vimrc` in `~/.ideavimrc`.
> :warning: Please note that IdeaVim currently parses `~/.ideavimrc` & `~/.vimrc` files via simple pattern-matching.
See [VIM-669](https://youtrack.jetbrains.com/issue/VIM-669) for proper parsing
of VimL files.
- Control the status bar icon via the [`ideastatusicon` option](doc/set-commands.md).
- Not familiar with the default behaviour during a refactoring? See the [`idearefactormode` option](doc/set-commands.md).
Some facts about Vim
-------
Let’s relax and have some fun now! Here are a few things we've found interesting during development
and would like to share with you.
- There are no such commands as `dd`, `yy`, or `cc`. For example, `dd` is not a separate command for deleting the line,
but a `d` command with a `d` motion.
Wait, but there isn't a `d` motion in Vim! That’s right, and that’s why Vim has a dedicated set of commands
for which it checks whether the
[command equals to motion](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/normal.c#L6468)
and if so, it executes `_` motion instead.
`_` is an interesting motion that isn't even documented in vi, and it refers to the current line.
So, commands like `dd`, `yy`, and similar ones are simply translated to `d_`, `y_`, etc.
[Here](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/normal.c#L6502)
is the source of this knowledge.
- `x`, `D`, and `&` are not separate commands either. They are synonyms of `dl`, `d$`, and `:s\r`, respectively.
[Here](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/normal.c#L5365)
is the full list of synonyms.
- Have you ever used `U` after `dd`? [Don't even try](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/ops.c#L874).
- A lot of variables that refers to visual mode start with two uppercase letters, e.g. `VIsual_active`. [Some examples](https://github.com/vim/vim/blob/master/src/normal.c#L17).
- Other [strange things](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/ex_docmd.c#L1845) from vi:
* ":3" jumps to line 3
* ":3|..." prints line 3
* ":|" prints current line
- Vim script doesn't skip white space before comma. `F(a ,b)` => E475.
