extension/src/goInstallTools: strengthing minimum go version requirement This change addresses problems in tools installation surfaced by the recent changes in go and gopls. * Automated toolchain switch for Go forwards compatibility The automated Go toolchain switch change added in go1.21 changed the meaning of 'go version' output different. Previously, it was meant exactly the version of the toolchain on the system. After go1.21, this is a go version for chosen for the workspace, computed based on the local toolchain version and the required go version dictated by go.mod or go.work. The extension has a facility to detect the go version used to compile tools, and ask users to rebuild them if they were built with older go standard libraries. When a local toolchain is older (for example, `go1.21.0`) than the workspace's required go version (`go1.22.0`), the 'go version' reports `go1.22.0`. The extension will detect tools that need recompiling to support `go1.22.0` project. That works as expected. However, when recompiling those tools with `go install`, the workspace's go version requirement doesn't come into play at all, but only the local toolchain's go version and the target tool's minimum required go version will be used in the toolchain switch decision making. As of today, none of the tools set their minimum required go version to go1.22.x, so if the local toolchain is still go1.21.0, `go install` will use go1.21.0 for build. We need to explicitly specify the minimum required version using the `GOTOOLCHAIN` environment variable. In this example, go install with `GOTOOLCHAIN=go1.22.0+auto` will address the issue. In this CL, - extend `getGoVersion` to allow the local toolchain version by specifying the optional GOTOOLCHAIN parameter. - change `getGoForInstall` to produce the correct GoVersion object that carries the true version of the local toolchain. (computed with `getGoVersion(..., 'local')`). - change `installTools` to append the `GOTOOLCHAIN` env var if the go version to be used for install is older than the project's minimum required go version. * More frequent crashes/malfunctions upon version mismatch Gopls is supposed to prompt when it detects it needs to be recompiled to process the modules that require newer go versions. The extension has relied this as the second, and more reliable defense mechanism. Unfortunately, bugs in the recent gopls stopped gopls from reliably detecting this case or, even made the gopls crash before showing the notification. Similar crashes can occur in other tools (golang/vscode-go#3168) when the version is mismatched. Previously, `installTools` warned users only if the go version for install was very old (e.g. go1.15). In this CL, - tighten `installTools`'s installation tool version check further. So, if the project requires a newer version of go and the go configured for tools installation (maybe due to outdated 'go.toolsManagement.go' setting) is older and is a version that cannot handle automated version switch (<go1.21), it prompts users. * Other changes Testing involving two versions of go is complex. Changed the runTest helper for 'Installation Tests' test suite to accept extra parameters and stubs, so we can make the installation function under test believe the local go chosen for installation is an older version. This CL also adjusted the logging of gopls restart activities. When gopls installed (automatically, or from the activation), the extension may attempt to restart the gopls. That may help investigate spurious gopls restarts obeserved during https://github.com/golang/vscode-go/issues/3307. This CL stops clearing of the Go outputChannel before tool installation or goplay run. This channel is now a log output channel, so it's better not to clear.

The VS Code Go extension provides rich language support for the Go programming language.
Welcome! 👋🏻
Whether you are new to Go or an experienced Go developer, we hope this extension fits your needs and enhances your development experience.
Install Go 1.18 or newer if you haven't already.
Install the VS Code Go extension.
Open any Go file or go.mod file to automatically activate the extension. The Go status bar appears in the bottom right corner of the window and displays your Go version.
The extension depends on go
, gopls
(the Go language server), and optional tools depending on your settings. If gopls
is missing, the extension will try to install it. The :zap: sign next to the Go version indicates the language server is running, and you are ready to go.
You are ready to Go :-) 🎉🎉🎉
If you are new to Go, this article provides the overview on Go code organization and basic go
commands. Watch “Getting started with VS Code Go” for an explanation of how to build your first Go application using VS Code Go.
See the full feature breakdown for more details.
In addition to integrated editing features, the extension provides several commands for working with Go files. You can access any of these by opening the Command Palette (Ctrl+Shift+P
on Linux/Windows and Cmd+Shift+P
on Mac), and then typing in the command name. See the full list of commands provided by this extension.
⚠️ Note: the default syntax highlighting for Go files is provided by a TextMate rule embedded in VS Code, not by this extension.
For better syntax highlighting, we recommend enabling semantic highlighting by turning on Gopls' ui.semanticTokens
setting. "gopls": { "ui.semanticTokens": true }
The VS Code Go extension supports both GOPATH
and Go modules modes.
Go modules are used to manage dependencies in recent versions of Go. Modules replace the GOPATH
-based approach to specifying which source files are used in a given build, and they are the default build mode in go1.16+. We highly recommend Go development in module mode. If you are working on existing projects, please consider migrating to modules.
Unlike the traditional GOPATH
mode, module mode does not require the workspace to be located under GOPATH
nor to use a specific structure. A module is defined by a directory tree of Go source files with a go.mod
file in the tree's root directory.
Your project may involve one or more modules. If you are working with multiple modules or uncommon project layouts, you will need to configure your workspace by using Workspace Folders. See the Supported workspace layouts documentation for more information.
If you'd like to get early access to new features and bug fixes, you can use the nightly build of this extension. Learn how to install it in by reading the Go Nightly documentation.
VS Code Go extension relies on the Go Telemetry to learn insights about the performance and stability of the extension and the language server (gopls
). Go Telemetry data uploading is disabled by default and can be enabled with the following command:
go run golang.org/x/telemetry/cmd/gotelemetry@latest on
After telemetry is enabled, the language server will upload metrics and stack traces to telemetry.go.dev. You can inspect what data is collected and can be uploaded by running:
go run golang.org/x/telemetry/cmd/gotelemetry@latest view
If we get enough adoption, this data can significantly advance the pace of the Go extension development, and help us meet a higher standard of reliability. For example:
These are just a few ways that telemetry can improve gopls. The telemetry blog post series contains many more.
Go telemetry is designed to be transparent and privacy-preserving. Learn more at https://go.dev/doc/telemetry.
We welcome your contributions and thank you for working to improve the Go development experience in VS Code. If you would like to help work on the VS Code Go extension, see our contribution guide to learn how to build and run the VS Code Go extension locally and contribute to the project.
