RubyMine 2020.3 EAP6: Improvements for the Editor, Navigation, and Code Assistance

RubyMine 2020.3 EAP6 is now available! Here are the main highlights of this build:

More intuitive Project tool window

We’ve added some new UX features to the Project tool window.

The Collapse All button is now coupled with the Expand All button so you can quickly expand all nested elements. Select it from the Project tool window or press ⌘+ (Ctrl + Numpad plus sign).

Expand all files in the Project tool window

To make sure you’re opening the appropriate file, you can now preview it. Select the file in the Project tool window and press Space.

Preview file content

If you want to work with several files open in the editor simultaneously, you can now do so with one simple shortcut. Select the file in the Project tool window and press Shift+Enter. The IDE will split the Editor window and open the file on the right-hand side.

Open a file in the right split

You can also use Shift+Enter to invoke this new split action from the Search Everywhere and Find Action popups.

Action to transpose characters

This tiny new feature comes in handy if you make a typo. It flips the current character with the one that follows it.

Transpose characters

You can add a keyboard shortcut for this action by going to Preferences / Settings | Keymap (or by looking up “Transpose” in Preferences).

Set a hotkey to the transpose action

Templates can generate multiple files

It is now possible to configure a custom template that creates several files at a time.

Go to Preferences / Settings | Editor | File and Code Templates, click + to create a new template, and then click the Create Child Template File icon next to the +.

You will see a new node appear under the parent file.

In the File name field, you can specify a pattern to generate a file name and a path using predefined variables that are listed in the Description section.

Use a template with multiple files

Now you can use your customized template. Let’s see how the files are generated:
