Research direction
Reproduce the issue in a TypeScript file using the supplied object and multiline generic-function example, comparing it with the standalone function. Inspect the TypeScript TextMate grammar files for the rules handling generic arguments inside object members; done means the multiline version receives the same correct highlighting as the standalone function.
Written by the indexing model from the issue text.
Description
Type: Bug
When having a function with generic type params in an object and the generic type params wrap into multiple lines, the TS syntax highlighting is broken.
To reproduce, just paste the following code in a .ts file and see the broken output:
const myObj = {
test<
A extends Record<string, any>,
C extends Record<string, any>,
B extends Record<string, any>,
>(a: A, b: B, c: C): Record<string, any>[] {
if ('hello' in a) {
console.log('Test');
}
return [a, b, c];
},
};
For reference, I added the same function but outside of the object which shows the correct/broken highlight in comparison:
