What did you do?

Snippet functions provided by gopls
variables.Print!and do it locally,
fmt.Printf("variable: %v\n", variable) will be displayed.

However, in containers created with devcontainer,
that functionality is not available.

Both vscode-go extension（.devcontainer.json） and gopls are installed（dockerFile）

Why is this?

Hi, is gopls otherwise working (i.e. normal completion works?).

Are you setting "experimentalPostfixCompletions"?

@findleyr Thanks for your reply

That was correct, I added that to devcontainer.json and it worked with containers.

But why do I need to explicitly add the following to devcontainer.json when gopls is installed in the container?

   "gopls": {
      "experimentalPostfixCompletions": true.
   }

Looking at the local setting.json, I see no problem even though there is no mention of "experimentalPostfixCompletions": true.

What is the difference?

The local version of gopls and the version of gopls installed in the container are the same.

@git-shochann Can you capture the gopls trace? For vscode, see https://github.com/golang/vscode-go/wiki/troubleshooting#collect-gopls-information We need the trace from the gopls start to the point it exchanges configuration messages. You can redact confidential file names, etc, but leave the initialization and configuration related messages untouched if possible.

experimentalPostfixCompletions settings should be true by default. In vscode-go, it corresponds to "gopls": { "ui.completion.experimentalPostfixCompletions": true }. But maybe configuration is not propagated correctly in devcontainer.

Sorry. My mistake. It was turned off in .code-workspace file.
