Phase 2 complete (plus a lil extra)

Phase 2

Function overloads

This was an interesting task to take on. I had to first figure out how to match a function’s signiture to its call. I couldn’t simply check if a signiture existed or not, I had to check which variation it satisfied. This involved reworking the way I stored signitures, and allowed a single object to hold them all for a certain function name. This way, it was a lot cleaner and put together.

STDLIB

After working through the project, I realized that I needed a way to define the primitive blocks used in Scratch. I didn’t think adding them in as a Typescript object was elegant, and it definently wasn’t extendable. Instead, I opted to expand the language syntax to allow generics, and therefore enable modular and clean code in the form of a katnip-defined STDLib.

Katnip LSP

This section is less in depth, because the setup wasn’t as hard. I look up some docs, and most of it was drag and drop. There exists a single file for defining the regex expressions with which to color the words on the page, and then I connected my error reporter to the lsp’s standard error reporter to further enhance the experience. Every 300ms or so, it updates, and tells the user where the errors are, just like any other language supported in text editors.
