TSServer: Find all reference for per overloaded function type

Search Terms

Find references, overload, function, overloaded function

Suggestion

Provide a mechanism to search references of a function with particular overloaded type

Use Cases

In current implementation find all references for overloaded function shows all references for every overload
Some times we need to find references of particular overload only (i.e. a overload is deprecated and we want to update all use cases)

Examples

/**
 * @deprecated
 **/
declare function fn():void; // overload 1
declare function fn(param:string):number; // overload  2

fn(); // use 1

const x = fn('a'); // use 2
const y = fn('b'); // use 3

Finding references for overload 1 should list use 1.
Finding references for overload 2 should list use 2 and use 3.

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Comienza investigando el comportamiento de TSServer con find-references para funciones sobrecargadas y cómo identifica una sobrecarga seleccionada. Define la finalización según los ejemplos: las referencias de la sobrecarga 1 incluyen únicamente use 1, mientras que la sobrecarga 2 incluye use 2 y use 3.
