This release introduces "zero config" gopls, which is a set of heuristics allowing gopls to Do The Right Thing when you open a Go file. We believe this addresses the two largest pain points we hear about from our users: difficulty configuring multi-module repositories, and working on multiple GOOS/GOARCH combinations. However, this is a large change to the way gopls models your workspace, and the dynamic loading/unloading of builds may be surprising in some cases. Your feedback on this new feature is greatly appreciated. See below for more details.

New Features

Simpler workspace configuration and improved build tag support

The headline feature of this release is a rewrite of gopls's logic for associating files with build configurations that enables gopls to give accurate answers when navigating almost any Go source file on your machine.

Most features of gopls rely on type information, which comes not from the file in isolation but depends on the relationship between the file and the other files in its package, and between the package and all its dependencies; this in turn depends on go.mod and go.work files. In effect, gopls needs to decide which go build command--which working directory, package arguments, GOOS, GOARCH, build tags, and so on--would cause each file to be processed by the compiler.

Previous versions of gopls only allowed one build per workspace folder, and users had to be careful to configure the right workspace root and build environment. As a result, users often encountered confusing error messages when they opened the wrong directory, or a file that was tagged for a different operating system or architecture--the dreaded "No packages found" error. This situation was improved by the introduction of go.work files, but still required configuration and a preexisting understanding of the code being edited.

With this release, gopls now allows multiple builds per workspace, and uses heuristics to automatically derive the set of active builds. Gopls will ensure that an active build contains every module with an open file in your workspace, adding new builds and GOOS/GOARCH combinations as needed to cover files that don't match the host operating system or architecture.

For example, suppose we had a repository with three modules: moda, modb, and modc, and a go.work file using modules moda and modb. If we open the files moda/a.go, modb/b.go, moda/a_windows.go, and modc/c.go, gopls will automatically create three builds:

In some cases this may cause gopls to do more work, since gopls is now tracking three builds instead of one. However, the scalability redesign we first announced in v0.12 allows us to avoid most of this work by efficient caching in a persistent store.

So, all gopls' navigation, query, analysis, and refactoring features should work equally well in both files. Notably, you'll see compiler diagnostics for the appropriate build in real time, making it much easier to make changes to cross-platform code.

Preview refactoring edits

Refactoring code actions now support resolving edits. This update enables features like code action previews within VS Code (triggered by Ctrl+Enter).

To take advantage of this new gopls feature, clients must register support via:

{
	"textDocument": {
		"codeAction": {
			"dataSupport": true,
			"resolveSupport": {
				"properties": ["edit"]
			}
		}
	}
}
