Implement some of Scala Metals' code actions #3358

Open santiweight opened 1 year ago

santiweight commented 1 year ago

Pretty open ticket. Link to Metals' CodeActions section

Here is a code action that seems like low-hanging fruit!

We could have a similar action, where if an upper-case symbol is undefined, we generate a template for a datatype with that name.

Define datatype now implemented here:
