Add the below in your settings to use Go modules.
Note: You will be prompted to install the latest stable version of
goplsas and when the Go tools team tag a new version as stable.
Extra settings to fine tune
gopls are available. Please see the gopls documentation for more information and recommended settings.
In addition to the Go language server, VS Code extension may use additional Go tools to provide features like code navigation, code completion, build, lint etc. Some tools may not have a good support for Go modules yet. Please report an issue if you encounter problems.
If you don't want to use the language server for any reason, then please know that not all the Go tools that this extension depends on supports Go modules. https://golang.org/issues/24661 is the issue used by the Go tools team to track the update of Go modules support in various Go tools.
Yes, you can and this is the path forward for module support in VS Code. Please be aware that the language server itself is in alpha mode with active development in progress. See the section right above this question for details.
Code navigation and code completion definitely works better when using
gopls. So, please give that a try.
If you are not using the language server, then this is mostly due to the limitation of the tools that power these features which are
gocode respectively. The Go tools team at Google are working on a language server which will be the long term solution for all language features.
Please try out the language server as described in the first section of this page.
If you don't want to use the language server then,
gogetdocin your settings, then log an issue in the gogetdoc repo
If you are not using the language server, this extension uses goreturns tool by default to format your files and auto import missing packages. Since this tool doesn't support modules, the auto import feature on file save no longer works.
Add the setting
"go.formatTool": "goimports" and then use
Go: Install/Update Tools to install/update
goimports as it has recently added support for modules.
