In your VSCode settings (JSON) add the following line;
Or if you are viewing your preferences/settings as the UI version, search for
useCodeSnippetsOnFunctionSuggest and set it to true. This will
- Add parentheses to the tailing end of function names.
- Complete function suggestions with parameter signatures, including the variable types.
There is also the setting of
go.useCodeSnippetsOnFunctionSuggestWithoutType which does the same, but omits the variable types.
You need the Visual Studio Code (Microsoft maintained) Go extension installed which can be found here.
