Quick fix to convert @typedef to type or interface

Search Terms

• typedef quickfix
• typedef jsdoc

Suggestion

I have lots of code in an old Closure Compiler-style project that looks like this:

/**
 * @typedef {{
 *   px: number,
 *   py: number,
 *   isZooming: boolean,
 *   isPanning: boolean,
 *   is2DPan: boolean,
 *   cancelNextDblclick: boolean,
 *   initializeMouseDown: (e: !Event, dygraph:!DygraphAny, context: !DygraphInteractionContext) => void
 * }} DygraphInteractionContext
 */

If I declare a variable with this type, I can see that TypeScript understands the @typedef:

type DygraphInteractionContext = {
    px: number;
    py: number;
    isZooming: boolean;
    isPanning: boolean;
    is2DPan: boolean;
    cancelNextDblclick: boolean;
    initializeMouseDown: (e: Event, dygraph: any, context: ...) => void;
}

I'd like to convert this to a type or interface. I can introduce a dummy variable, copy the TS-style type declaration and paste it in to do the conversion.

But it'd be easier if there were a quickfix!

Use Cases

Migrating a project that used JSDoc-based typing. A workaround is available, but a quickfix would be a big improvement.

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.

La issue non fornisce file del repository, test o punti di ingresso. Inizia esaminando l’architettura dei quick-fix di TypeScript e i codefixes esistenti relativi a JSDoc, quindi determina la conversione prevista per l’esempio @typedef mostrato. Il lavoro è completato quando un quickfix converte i typedefs JSDoc supportati in un type o un interface senza modificare l’output di runtime.
