Release notes

Generics: support for the go:linkname directive

The go:linkname compiler directive is now supported. The Missing function body false-positive error has been fixed.

Go support: fuzz testing

If you click the green triangle icon in the gutter next to your fuzz test, you will see different options for running the test. If the test fails, the failing seed corpus entry will be written to a file and placed in your package directory in the testdata folder.

The path to this file will also appear in the console as a clickable link. If you click the link, the file will be opened in the IDE, and you will see a green triangle icon at the top of the file. Clicking on this icon will run go test with the failing seed corpus entry.

Go support: loong64 in the Arch list

Go 1.19 is introducing a new loong64 architecture.

Go support: support of Append, Appendln, and Appendf

Go 1.19 introduces three new functions to the fmt package: Append, Appendln, and Appendf.

GoLand identifies formatting verbs inside strings in Appendf functions.

Performance optimization: stop scanning ~/go/pkg/mod/cache

When you work in GoLand, the IDE scans GOMODCACHE (~/go/pkg/mod) to suggest dependencies. GOMODCACHE includes a cache subdirectory that contains some metadata and other information that is not needed for GoLand to work correctly.

We decided to stop scanning the cache subdirectory. This folder can be fairly large, and we hope that excluding it from the scan will improve performance.

Build constraints: support for the unix build constraint

GoLand now supports the new unix build tag that matches any Unix or Unix-like system.

Quick documentation: new documentation-related features

The following quick documentation features were implemented:

• Tooltips for Go keywords.

  

• Documentation for channel types.

  

• Report methods on both value and pointer receivers.

  

• Improved quick documentation for iota.

  

• Additional information when you initialize maps, arrays, slices, and structs.

  

• Documentation for type assertions.

  

• Documentation for blank identifiers.

  

• Documentation about empty interfaces.

  

• Documentation about type aliasing and type definition.

  

Generics: improvements

The following inspections were introduced:

• Report unused type parameters.

  

• Quick-fix to delete a type parameter with an empty parameter list.

  

• Report union of interfaces with methods. For more information about this limitation, see the issue #45346 in the golang repository on github.com.

  

• Completion for a type parameter when typing a method’s receiver.

  

• Report usage of a type parameter as a constraint.

  

• Irregular usage of iota.

  

• Constants with the name iota collide with the builtin constant

  

User interface: the Merge All Project Windows action
