Generic constructor with more than one generic type can break syntax highlighting.

JavaScript and TypeScript Nightly version:

Last released - 4/4/2023, 02:09:37

Code

export class Foo {
    readonly bar = {
        map: new Map<
            Type1, Type2>([]) 
    };

    private function() {
        return 1;
    }
}

The code above breaks syntax highlighting, I have also tested in insiders vscode with nightly typescript.

It is fine, if both generics are on the same line as the main type:

If there is only 1 generic, it does slightly better, the highlighting of the generic is wrong, but the rest of the file is ok.

Or if the argument to the constructor is not a list, this it is also recoverable, although both the highlighting of the generic, and the closing angle bracket are wrong.

No se especifica ningún archivo fuente ni ninguna prueba. Empieza reproduciendo el ejemplo multilinea de TypeScript de un constructor genérico incluido en el issue, compáralo con las variantes que funcionan y sigue la gramática TypeScript TextMate responsable del resaltado de sintaxis. Se considera terminado cuando el código mostrado y el archivo que lo rodea conservan el resaltado correcto.
