Autocomplete shortcuts

[pervoj]

It would be nice to have a feature in VLS similar to the one in IntelliJ. Simple shortcuts that could be used to autocomplete a longer command.

For example, main for the main() method, sout for stdout.printf(), or sirl for stdin.read_line(). Or even vmain for the main() method of type void.

I'm fairly sure that's called a Snippet. Yeah having snippets would be a nice addition to the language server itself.

We already have many snippets in VLS for common statements/expressions:
