prettify complex type display (for generic-heavy types)

Suggestion

give indentations + line-changes on type representation. User config for this might be an option.

Examples

suppose I have some generic-heavy function someFunc that returns

const a = someFunc();
// typeof a = RootGeneric<GenericA, GenericB<number, SubGenericB_A<number> ...
//  full type not shown 😭 

A better output can be:

// typeof a = 
RootGeneric<
    GenericA, 
    GenericB<
        number, 
        SubGenericB_A<number> ...

more things:

• editors can implement "expand(+)" buttons ?
  (collapsed-tree-view)

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.

Aucun fichier, test ou point d’entrée n’est nommé. Commencez par les exemples de types fortement génériques de l’issue et déterminez la portée prévue pour l’indentation, les changements de lignes, la configuration utilisateur et l’expansion de l’éditeur. Le travail est considéré comme terminé lorsqu’un design convenu et un plan d’implémentation pour le comportement d’affichage des types sont définis.
