Please note that to use GoLand 2023.2 RC, you need to have an active subscription or start a 30-day trial.

The Release Candidate provides all of the new features and improvements already announced during our current EAP cycle and expected in the major 2023.2 release.

Our recent EAP blog posts have more details about these updates, but here are some of the highlights:

This RC build includes some new features as well. Let’s take a look!

Support for errors.Is and errors.As

We’ve implemented two inspections that will highlight the cases where errors.Is or errors.As should be used. There are also quick-fixes that will help you refactor the existing code to errors.Is or errors.As usages.

The first inspection highlights the direct comparisons of errors.

In Go 1.13 and later, errors can be wrapped using the fmt.Errorf function with the %w verb, and direct comparison of errors using the equality check may fail on wrapped errors.

The preferred way of checking for a specific error is to use the errors.Is function from the standard library. GoLand now has a quick-fix that suggests converting direct error comparisons to usages of errors.Is.

The second inspection highlights type assertions and type switches on errors, such as  err.(*MyErr) or switch err.(type), as they may also fail on wrapped errors.

The preferred way in Go 1.13 and later is to use errors.As. Our new quick-fix suggests converting type assertions and type switches on errors to usages of errors.As.

Support for min, max, and clear

GoLand 2023.2 RC provides basic support for min, max, and clear – the new functions introduced in Go 1.21.

That’s it for today! We’d love to hear what you think about the new features. Get in touch with us on Twitter, leave your comments below, report any issues in our tracker, or drop us a message in the Gophers Slack #goland channel. Thanks!
