Enums and interfaces do not have definitions in quick info/tooltips

[LAITONEN]

The issue might be related to this one, but mine is not about version 3.0, and is not solely about imports.

Suggestion

Hovering over enums and interfaces, should show their definition, i.e. I have this enum (or an interface):

enum enumName {
    ONE = 1;
    TWO = 2;
    THREE = 3;
}

If I hover over this enum, wherever I use it (whether it is imported to another file or used locally where it is declared), I would like to see what this enum is all about (essentially what are the properties).

This is what I see right now when I hover over enums or interfaces:

As a workaround, I currently need to add this type of JSDoc comments right above the enum declaration.

/** Props:
*    @param ONE 1;
*    @param TWO 2;
*    @param THREE 3;
*/

Which yields to:

Use Cases

This feature would save time & effort.
The shortcoming of the current approach is that either need to add ${2+numberOfEnumProperties} lines of comments or go to the file, where enum is declared, locate the enum there and then familiarize myself with its properties.

Checklist

I am not that experienced to be able to answer the questions below.

• 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. new expression-level syntax)

Also, if I have interface, which extends another interface:

interface One {
    one: number;
}

interface Two extends One {
    two: string;
}

And I use interface Two somewhere and hover over it, I will get the same dull description as I got on the second screenshot in the initial post with interfaceName, so not only there is no description of a specified properties, but it does not even show which interfaces it extends.

I agree. hovering over a type name to get a pop-up with the same text is rather useless. we can do better.
