Setup

• IdeaVim can be installed via Settings | Plugins. See the detailed instructions.

• Use Tools | Vim Emulator in the menu to enable or disable emulation.

• Use the ~/.ideavimrc file as an analog of ~/.vimrc (learn more). The XDG standard is supported, as well.

• Shortcut conflicts can be resolved by using:

  • On Linux & Windows: File | Settings | Editor | Vim & File | Settings | Keymap,
  • On macOS: Preferences | Editor | Vim & Preferences | Keymap,
  • Regular Vim mappings in the ~/.ideavimrc file.

Suggested options (click to see)

Here is also a list of the suggested options from defaults.vim

" Show a few lines of context around the cursor. Note that this makes the
" text scroll if you mouse-click near the start or end of the window.
set scrolloff=5

" Do incremental searching.
set incsearch

" Don't use Ex mode, use Q for formatting.
map Q gq

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

source ~/.vimrc

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 standard. Put your settings to $XDG_CONFIG_HOME/ideavim/ideavimrc file.

Executing IDE Actions

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

Executing actions:

• :action {action_id}
  • Execute an action by {action_id}. Works from Ex command line.
  • Please don't use :action in mappings. Use <Action> instead.
• <Action>({action_id})
  • For the mappings you can use a special <Action> keyword. Don't forget the parentheses.
  • E.g. map gh <Action>(ShowErrorDescription) <- execute hover on gh.
  • ⚠️ Mappings to <Action> don't work with noremap. If you know the case when it's needed, please let us know.

Finding action ids:

• IJ provides IdeaVim: track action Ids command to show the id of the executed actions. This command can be found in "Search everywhere" (double shift).

  "Track action Ids" Details (click to see)

  

• :actionlist [pattern]

  • Find IDE actions by id or keymap pattern (E.g. :actionlist extract, :actionlist <C-D)

Examples:

" Map \r to the Reformat Code action
:map \r <Action>(ReformatCode)

" Map <leader>d to start debug
:map <leader>d <Action>(Debug)

" Map \b to toggle the breakpoint on the current line
:map \b <Action>(ToggleLineBreakpoint)

Some popular actions:

QuickJavaDoc - Quick Documentation (not only for java, all languages)
ShowErrorDescription - Show description of the error under the caret (cursor hovering)
QuickImplementations - Quick Definition

Vim Script

IdeaVim can execute custom scripts that are written with Vim Script. At the moment we support all language features, but not all of the built-in functions and options are supported.

Additionally, you may be interested in the Vim Script Discussion or Vim Script Roadmap.

IDE specific options

You can evaluate the has('ide') function call and get 1 if it was called with IdeaVim or 0 if the function was called from Vim/NeoVim.
The option &ide contains the name and edition of your IDE, for example, "IntelliJ IDEA Ultimate Edition".
To see its value for the current IDE you are using, execute the :echo &ide command.
To write an IDE-specific configuration, use Vim's regexp match operators =~? (case-insensitive) / =~# (case-sensitive)

Example config:

" options and mappings that are supported by both Vim and IdeaVim
set nu
set relativenumber

if has('ide')
  " mappings and options that exist only in IdeaVim
  map <leader>f <Action>(GotoFile)
  map <leader>g <Action>(FindInPath)
  map <leader>b <Action>(Switcher)

  if &ide =~? 'intellij idea'
    if &ide =~? 'community'
      " some mappings and options for IntelliJ IDEA Community Edition
    elseif &ide =~? 'ultimate'
      " some mappings and options for IntelliJ IDEA Ultimate Edition
    endif
  elseif &ide =~? 'pycharm'
    " PyCharm specific mappings and options
  endif
else
  " some mappings for Vim/Neovim
  nnoremap <leader>f <cmd>Telescope find_files<cr>
endif

IdeaVim tips and tricks

• Use the power of IJ and Vim:

  • set ideajoin to enable join via the IDE. See the examples.
  • 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.

• Use your vim settings with IdeaVim. Put source ~/.vimrc in ~/.ideavimrc.

• Control the status bar icon via the ideastatusicon option.

• Not familiar with the default behaviour during a refactoring? See the idearefactormode option.

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 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 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 is the full list of synonyms.

• Have you ever used U after dd? Don't even try.

• A lot of variables that refers to visual mode start with two uppercase letters, e.g. VIsual_active. Some examples.

• Other strange things 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.
