JetBrains adds Go features, including sharing, fixes and inspections

The hardworking team at JetBrains has released GoLand 2020.2, with a slew of new features and fixes for code developers.

JetBrains‘ Ekaterina Zharova said the new version spans Go module features, improved problem presentation, code inspection and editing functionality, references and navigation support, “as well as the ability to configure wrapping for call arguments, function parameters, and composite literal elements”.

“On top of that, we’ve added experimental support for generics (also known as type parameters), the ability to share code to the Go Playground from the editor, updates for version control, including WSL 2 support for Git on Windows, and more,” she writes in the JetBrains blog post.

A “long-awaited” ability to add carets per selected line has also been rolled out to help developers type more quickly.

There’s also a tutorial inside the IDE on the Welcome screen of the new version, notes Zharova.

Some detail on the changes

The Go modules now support GOMODCACHE environment variable – out with Go 1.15, and the IDE provides a closing brace immediately when the opening brace is typed. There is also support for commenting in go.mod files.

A number of warnings, errors and typos are displayed in the current file, while the Problems tool window offers descriptions of current-file warnings and errors and enables immediate fixes via Alt+Enter. And there’s a check for malformed struct tags.

“A new code inspection handles possible problems with string(int) conversions and lets you fix them easily,” Zharova says.

With the new version of GoLand, coders can now use the Put arguments on separate lines and Put arguments on one line intention actions to split or join call arguments, function parameters, and composite literal elements. Preview intention actions and quick-fixes in Intentions Preview.

They can also take control of variadic arguments with Introduce Variable refactoring, which packs them into a new slice variable.

“Inline Variable, conversely, unpacks a slice into variadic arguments.”

In addition, projects can now be saved as custom templates, and code can be shared directly to Go Playground directly from the editor.
