gopls, the Go language server
gopls (pronounced "Go please") is the official Go language server developed
by the Go team. It provides IDE features to any LSP-compatible editor.
You should not need to interact with gopls directly--it will be automatically
integrated into your editor. The specific features and settings vary slightly
by editor, so we recommend that you proceed to the
documentation for your editor below.
Editors
To get started with gopls, install an LSP plugin in your editor of choice.
If you use gopls with an editor that is not on this list, please send us a CL
updating this documentation.
Installation
For the most part, you should not need to install or update gopls. Your
editor should handle that step for you.
If you do want to get the latest stable version of gopls, run the following
command:
go install golang.org/x/tools/gopls@latest
Learn more in the advanced installation instructions.
Learn more about gopls releases in the release policy.
Setting up your workspace
gopls supports both Go module, multi-module and GOPATH modes. See the
workspace documentation for information on supported
workspace layouts.
Configuration
You can configure gopls to change your editor experience or view additional
debugging information. Configuration options will be made available by your
editor, so see your editor's instructions for specific details. A
full list of gopls settings can be found in the settings documentation.
Environment variables
gopls inherits your editor's environment, so be aware of any environment
variables you configure. Some editors, such as VS Code, allow users to
selectively override the values of some environment variables.
Support Policy
Gopls is maintained by engineers on the Go tools team, who actively monitor the Go and VS Code Go issue trackers.
Supported Go versions
gopls follows the
Go Release Policy,
meaning that it officially supports the last 2 major Go releases. Per
issue #39146, we attempt to maintain best-effort
support for the last 4 major Go releases, but this support extends only to not
breaking the build and avoiding easily fixable regressions.
In the context of this discussion, gopls "supports" a Go version if it supports
being built with that Go version as well as integrating with the go command
of that Go version.
The following table shows the final gopls version that supports a given Go version. Go releases more recent than any in the table can be used with any version of gopls.
| Go Version | Final gopls version with support (without warnings) |
|---|---|
| Go 1.12 | gopls@v0.7.5 |
| Go 1.15 | gopls@v0.9.5 |
Our extended support is enforced via continuous integration with older Go versions. This legacy Go CI may not block releases: test failures may be skipped rather than fixed. Furthermore, if a regression in an older Go version causes irreconcilable CI failures, we may drop support for that Go version in CI if it is 3 or 4 Go versions old.
Supported build systems
gopls currently only supports the go command, so if you are using
a different build system, gopls will not work well. Bazel is not officially
supported, but may be made to work with an appropriately configured
go/packages driver. See
bazelbuild/rules_go#512
for more information.
You can follow these instructions
to configure your gopls to work with Bazel.
Troubleshooting
If you are having issues with gopls, please follow the steps described in the
troubleshooting guide.
