IntelliJ-like super-completion

[channingwalton]

Is your feature request related to a problem? Please describe.

When completing its hard to see what the parameters are for constructors or fields. Metals could provide support like Intellij's super completion.

Describe the solution you'd like

For example, given case class Foo(a: String, b: Int), a code action on Foo(<cursor>) gives Foo(a = ???, b = ???)

Describe alternatives you've considered

Only vim specific hacks but no idea how.

Thanks for reporting, this should actually work already, but might not be super obvious. If you write a parameter name the last option should be Autofill with default values option.

It's not yet available for Scala 3

Dang! This was my bad I told him to create it. I had no idea this existed. Nice!

It's kind of hard to notice since we didn't want it popping as the first thing. There was a worry that this might lead to more errors, since we try to fill in a value if there is only one of that type in scope.

This also sort of requires you to know what the param is. It'd be cool to not have to know and instead trigger a code action with nothing in the params yet and get this as an option. Maybe we can leave this open for the code action option?

That should fine, sure!
