extendedDiagnostics is difficult to use if you have composite projects

Suggestion

extendedDiagnostic outputs per-project statistics, but it's difficult to map those statistics back to the sub-projects. It would be great to start each section with tsconfig path that the statistics relate to.

✅ Viability Checklist

My suggestion meets these guidelines:

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

⭐ Suggestion

Add tsconfig.json path for each diagnostic section.

💻 Use Cases

I want to use this for understanding high level performance of our different projects without having to open traces.

Beginne mit dem extendedDiagnostics-Einstiegspunkt und reproduziere die Ausgabe für ein Composite-Projekt mit mehreren Teilprojekten. Verfolge, wie jeder Statistikabschnitt pro Projekt ausgegeben wird; abgeschlossen ist die Aufgabe, wenn jeder Abschnitt den tsconfig-Pfad angibt, den er beschreibt, wobei das bestehende Diagnoseverhalten erhalten bleibt.
