Using Vim Editor Emulation in RubyMine (IdeaVim)
Before you start
Make sure that:
- You are working with RubyMine version 8.0.0 or higher. If you still do not have RubyMine, download it from this page. To install RubyMine, follow the instructions, depending on your platform.
- You have at least one Ruby interpreter properly installed on your computer. You can download an interpreter from this page.
Downloading and installing IdeaVim plugin
You see the list of plugins currently installed on you computer. However, the IdeaVim plugin is not among them. Click the button Browse JetBrains plugins. RubyMine shows the contents of the huge JetBrains repository... you can type the word "vim" in the search field to narrow down the list:
After installing the plugin, it actually becomes available after RubyMine restart.
What happens to RubyMine's UI after restart?
After RubyMine restart, this check command is selected. You can disable Vim by clearing this check command.
Both Vim and RubyMine are keyboard-centric. With IdeaVim plugin, it is quite possible that RubyMine's keymap runs into a conflict with the Vim keymap. That's why RubyMine allows you choosing which keyboard shortcut you prefer for a certain action. This is how it's done.
Open Settings/Preferences dialog, and click Vim Emulation:
In the Shortcut column, select the shortcut you want to configure. Next, in the Handler column, click the corresponding cell, and see the drop-down list of three possible options (Undefined, IDE, Vim):
If you leave the handler undefined, then, on pressing the shortcut, say, Ctrl+B, RubyMine shows the banner.
OK, now that you have Vim enabled, you see that the cursor has changed its shape - now it is a block, which means that you are in the Normal mode :
If you want to enter the Insert mode, press
i, and the cursor will turn into a line:
In this mode you can type new or change the existing code. Same way, you can enter the various Vim modes: for example, press
r for the Replace mode.
By the way, as soon as you enter Vim emulation, it is also reported in the Status bar.
To return to the Normal mode, press Escape.
