Use related error spans for "implement abstract class" errors

See original GitHub issue


TypeScript Version: 3.6.0-dev.20190810

Search Terms:

  • abstract class
  • related error spans
  • diagnostics

Problem For the TypeScript:

abstract class A {
	abstract b(): void;
	abstract c(): void;

class B extends A { }

The typescript server currently generates two errors on B, one for b not being implemented and one for c not being implemented.

Having two errors causes VS Code to show a fix all... quick fix even though the single implement abstract class quick fix will resolve both errors. See

Proposal Instead of generating two errors in this case, generate a single, generic diagnostic that states something like: B does not implement all abstract members of A and on that diagnostic return related spans that state specifically which members are not implemented (b and c).

Go for it! Start at the checker to consolidate the error messages, and then work within src/services/codefixes.

Thanks @FlyingPumba!
