Make it clear that this is in UTF-8? Or just take a string napi_value instead?

Maybe it'd be easier to take a napi_value instead.

don’t we technically need to free() this?

Pointer star goes with the type.

We’re inconsistent about that in this file, and I think this can pass as “idiomatic for C code”

Switched script parameter to napi_value, made sure that the script ->IsString(), and added a test to make sure it throws if it isn't.

In the future we might want to have an equivalent for V8's Script or UnboundScript, but this LGTM and should suffice for now.

@gabrielschulhof sorry, missed reviewing this PR. @MSLaguana and I were looking at it for implementation in node-chakracore and we had a question- if someone was debugging their script and a script executed from this API was on the stack- what is the "filename" they expect to see? Dynamic code or something equivalent? Should there be a way of modules identifying themselves to the debugger? Or should these frames be considered "library code" and hidden from the debugger?

gabrielschulhof · 2017-09-15T09:53:46Z

@digitalinfinity maybe we should treat it like an eval. Chrome developer tools opens a new tab and calls it "VM<number>" where number is probably some internal counter or something like that. It paints the tab a different colour. In fact, I ran `node --inspect-brk test/addons-napi/test_general/testNapiRun.js` and when I stepped into `addon.testNapiRun()` it behaved exactly like `eval()`.
