[dependabot]

Bumps golang.org/x/tools from 0.7.0 to 0.8.0.

Release notes

Sourced from golang.org/x/tools's releases.

gopls/v0.8.0

Go version support

Support for Go 1.18

Version 0.8.0 of gopls supports features added to Go 1.18, specifically:

• Support for multi-module workspaces using go.work files.
• Diagnostics for Fuzz tests.
• Improved support for generics.

To use these features, gopls must be installed using Go 1.18. See go.dev/dl for the latest status of Go 1.18 -- as of writing Go 1.18 is not yet released, but Go 1.18 RC1 may be used.

Dropped support for Go 1.12

Version 0.8.0 of gopls no longer supports building at Go 1.12. See golang/go#50827 for more details.

New Features

go.work integration

Gopls now supports multi-module workspaces using go.work files. To use this feature, create a go.work file that includes the modules you want to work on, and then open your editor to the directory containing go.work. For more information, see the go.work reference, or the gopls documentation for multi-module workspaces.

Diagnostics for Fuzz tests

When writing Fuzz tests, gopls provides diagnostics for invalid arguments to Fuzz.

Improved support for generics

Honor the language version configured in go.mod

gopls now provides diagnostics for language features based on the go directive in the applicable go.mod file for a package.

For some errors related to incompatible language versions, gopls offers a quick-fix to update the go.mod Go version. (note that if the go.mod file is open, it may need to be saved in order for language version changes to take effect)

Improved completion with type parameters

Gopls autocompletion is improved in several contexts when using generic types.

New code action to add missing method stubs

Gopls now provides a code action to implement missing methods.

Improved performance and accuracy for workspace symbol requests
