Planned Features

Find references

This feature will likely be implemented in this order:

• top level symbols like macros, modules, packages, and interfaces
• scope members
• struct members

Semantic Token Highlighting

This will provide additional coloring for variable names, distinguisihing between wires, registers, and parameters.

For classes/functions it will distinguish betweeen instance variables, function args and locals.

Inlay Hints

Ports - Show the type of ports in instances

Params - Show the resolved value of parameters

Signals - Show the resolved type of wires and registers, and show the value when a waveform is connected

Macros/Functions - Show the positional argument names

Wildcard Ports - Show which signals are passed through

Wildcard Imports - Show which symbols are used from the import

Formatter

This one is pretty self explanatory, but it will live in the slang repo and also be shipped as a standalone binary. In order to make formatting nice for the language server, basic formatting functions already exist in this repo. This includes things like squashing white spaces to condense hovers/completion types, and left aligning blocks of text for hovers and completion docs.
