What is the best way to retrieve an object within a Visual Studio Code extension?

When working on a new Visual Studio Code extension, how can I determine the current class that my cursor is in?

For instance:

export class MyClassA {

  parameter1: number = 5;

  myFunc() {
    return parameter1 * 2;
  }

}

export class MyClassB {
   anotherParamenter = null;
}

If I am editing within the myFunc method and trigger registerHoverProvider, I want to be able to identify that I'm inside the MyClassA class.

Is there a way to access the object or just the cursor position for this purpose?

Answer №1

The information presented in a code editor is heavily influenced by the programming language being used. To understand the syntax and meaning of the code written, a parser specific to that language is required.

Therefore, the initial step involves implementing a parser or utilizing parsing services offered by other software tools. Once this foundation is established, you can utilize it to identify the syntactic structure (such as myFunc in MyClassA within module foo) and use this to generate data for your hover provider.
