Re: How to identify which script is being worked in

I'm presume the context is from within a C++ method with a signature like |(JSContext* cx, unsigned argc, JS::Value* vp)| that you are triggering from JS. In that case you should be able follow a chain similar to CallArgs::calleev() -> JS_GetFunctionScript ->  JS_GetScriptFilename.

(Depending on your use case, you may want to consider targetting version 78. It will become the ESR version and security patches will continue to be generated for it, as well more embedders will target that version).

Previously, we would store some information in the context private data so as to identify the correct script. However, this is now proving unsuitable given that we can only have one context.
