The RubyMine 2020.1 version is officially released. The main update highlights include:
navigation
The navigation function has been improved, and you can now seamlessly jump between Rails entities and database schemas, and between parent and child methods.
test
It is now possible to create new tests for any class, making test creation easier. RubyMine will copy the directory structure according to the path of the test object.
LightEdit mode
When you need to quickly edit files, you can use the new LightEdit mode. It runs much faster than standard mode because it can open files without loading projects.
terminal
You can now split terminal sessions vertically or horizontally to run them side by side. You can create, navigate, or close a split terminal session by calling the context menu from the terminal.
