As prompted [this issue](https://github.com/golang/go/issues/38963) it is unclear how to setup build tags in gopls in vscode. vscode has a configuration section specific for go build tags but it is not honored by gopls which instead requires GOFLAGS environment variable to be set with the -tags flag.

# VSCode
|
|
|
|
Use the [VSCode-Go] plugin, with the following configuration:
|
|
|
|
```json5
|
|
"go.useLanguageServer": true,
|
|
"[go]": {
|
|
"editor.formatOnSave": true,
|
|
"editor.codeActionsOnSave": {
|
|
"source.organizeImports": true,
|
|
},
|
|
// Optional: Disable snippets, as they conflict with completion ranking.
|
|
"editor.snippetSuggestions": "none",
|
|
},
|
|
"[go.mod]": {
|
|
"editor.formatOnSave": true,
|
|
"editor.codeActionsOnSave": {
|
|
"source.organizeImports": true,
|
|
},
|
|
},
|
|
"gopls": {
|
|
// Add parameter placeholders when completing a function.
|
|
"usePlaceholders": true,
|
|
|
|
// If true, enable additional analyses with staticcheck.
|
|
// Warning: This will significantly increase memory usage.
|
|
"staticcheck": false,
|
|
}
|
|
```
|
|
|
|
VSCode will complain about the `"gopls"` settings, but they will still work. Once we have a consistent set of settings, we will make the changes in the VSCode plugin necessary to remove the errors.
|
|
|
|
If you encounter problems with import organization, please try setting a higher code action timeout (any value greater than 750ms), for example:
|
|
|
|
```json5
|
|
"[go]": {
|
|
"editor.codeActionsOnSaveTimeout": 3000
|
|
}
|
|
```
|
|
|
|
To enable more detailed debug information, add the following to your VSCode settings:
|
|
|
|
```json5
|
|
"go.languageServerFlags": [
|
|
"-rpc.trace", // for more detailed debug logging
|
|
"serve",
|
|
"--debug=localhost:6060", // to investigate memory usage, see profiles
|
|
],
|
|
```
|
|
|
|
See the section on [command line](command-line.md) arguments for more information about what these do, along with other things like `--logfile=auto` that you might want to use.
|
|
|
|
You can disable features through the `"go.languageServerExperimentalFeatures"` section of the config. An example of a feature you may want to disable is `"documentLink"`, which opens [`pkg.go.dev`](https://pkg.go.dev) links when you click on import statements in your file.
|
|
|
|
### Build tags
|
|
|
|
build tags will not be picked from `go.buildTags` configuration section, instead they should be specified as part of the`GOFLAGS` environment variable:
|
|
|
|
```json5
|
|
"go.toolsEnvVars": {
|
|
"GOFLAGS": "-tags=<yourtag>"
|
|
}
|
|
```
|

# VSCode Remote Development with gopls
|
|
|
|
You can also make use of `gopls` with the [VSCode Remote Development](https://code.visualstudio.com/docs/remote/remote-overview) extensions to enable full-featured Go development on a lightweight client machine, while connected to a more powerful server machine.
|
|
|
|
First, install the Remote Development extension of your choice, such as the [Remote - SSH](https://code.visualstudio.com/docs/remote/ssh) extension. Once you open a remote session in a new window, open the Extensions pane (Ctrl+Shift+X) and you will see several different sections listed. In the "Local - Installed" section, navigate to the Go extension and click "Install in SSH: hostname".
|
|
|
|
Once you have reloaded VSCode, you will be prompted to install `gopls` and other Go-related tools. After one more reload, you should be ready to develop remotely with VSCode and the Go extension.
