Answer 2

JavaScript is not a compiled language and it is not, by any stretch of the imagination, compatible with C++, so #include doesn't stand a chance of importing JavaScript code. In fact, the notion of a header file doesn't even exist in JavaScript.

There are several JavaScript engines that can be integrated into a compiled language, including:

1. The Mozilla project's SpiderMonkey.
2. Google Chrome's V8.
3. A whole bunch of others.

Answer 3

A detailed tutorial for embedding JS in C++ via Mozilla's SpiderMonkey engine can be found here Basically you need to include jsapi.h, create/configure/cleanup the JS engine as the tutorial describes (populating the char* script with your string literal JS source code and passing the resulting character array to JS_EvaluateScript), and then link against the SpiderMonkey library when you build the executable for your system. Note that this tutorial goes on to explain how to call C functions from JS and how to call specific JS functions from C, which is also interesting and possibly more appropriate for the OP's situation.

Answer 4

You might want to port your JS to C++; this should be a fairly simple task, as the two languages are moderately alike.

Simply porting the functionality is likely to be far simpler than actually trying to use a JS parsing library, and likely less error prone.
