RubyMine 2020.2 EAP4: Improved Completion, Support for Git Installed in WSL2, and More

RubyMine 2020.2 EAP4 is now available! Here are the main highlights in this build:

Improved completion for standard library methods

We’ve improved completion for many of the common standard library methods (such as Array#sort_by, Hash#each, and many others). RubyMine will now suggest more accurate methods in completion.

For example, the completion will now recognize the key and value types of a hash and suggest methods based on them:

New intention action to sort hashes by their keys

We’ve added a new intention action that sorts items in a hash alphabetically by key:

Sort hash by key intention action

This intention action also works for hashes with different key types too. In this case, the keys are grouped by their type and then sorted. However, it’s not available for hashes that contain a hash deconstruction, as this would change the semantics of the code.

Support for Ruby 2.7 beginless ranges

RubyMine now correctly recognizes beginless ranges (introduced in Ruby 2.7). It will also show a warning if a beginless range is used in Ruby 2.6 or below.

Support for Git installed in WSL2

WSL is becoming an important part of the development process on Windows and we are working on supporting all the necessary workflows in our IDEs.

The upcoming RubyMine 2020.2 now supports Git installed in WSL2 for working with projects located in Linux or Windows file systems.

The IDE can switch between Git executables depending on the project location. When a project is opened from WSL (via \wsl$ path), the IDE will not only automatically switch to Git from WSL but it will also provide you with the ability to use all the Git-related features in the IDE.

Please note that the upcoming RubyMine 2020.2 allows you to use Git only from WSL2, which is available in the May update of Windows 10, version 2004. The IDE will not support WSL1 because, unfortunately, Git from WSL1 does not return output reliably when called from Windows, and this could lead to incorrect results from Git commands – see IDEA-242469 and the corresponding WSL request.
