Keep resource name for function objects?

[martijnthe]

Hey JrS people!

I'm trying to implement a native binding much alike Node's require.resolve()
The tricky thing about the require.resolve function is that when using a relative path, i.e. require.resolve('./thing.js') the look up happens relative to the source file in which the require.resolve() call was written.

I noticed that for the JerryScript debugger support, jerry_parse_named_resource was added, which seemed promising at a glance. Unfortunately, the "resource name" is merely passed off to the debugger client and not kept around.

Any suggestions on how to solve this?

I guess I want an API like const jerry_char_t *jerry_get_current_resource_name(void); that would return the currently executing resource name (or NULL if no named resource is executing / it's not available).

For reference, V8 has a GetScriptName() method on the StackFrame class which is similar to what I'm looking for.

Easy to keep them, but it consumes memory. The question is how can we do this effectively.

Perhaps a new feature flag will be needed.

I think to be able to implement Node.js' __filename you'd also need to have this API.
