I have been digging around for quite some time now trying to find a working example to implement a SignatureHelpProvider in typescript for a custom programming language used internally within my company.
In my time so far I have a minimally working example that provides "Parameter Hints" (another name for what the SignatureHelpProvider result is) for methods like:
ADD(1, 2) - things work somewhat well for basic 1 level deep methods.
However, things are getting very complex and difficult to manage for things like:
ADD(1, ADD(1, SUBTRACT(100, 5))) etc
In doing some research, someone suggested that building an AST is the right approach for managing this type of project. However, I have not been able to find any complete examples online for implementing SignatureHelpProvider with a custom programming language.
Does anyone know of a good resource / example to use for implementing SignatureHelpProvider in a custom programming language?
Have reviewed the online docs extensively, and poured over VS Code's internal implementation, no dice so far.
