Hey everyone. I'm trying to figure out how to call a C++ function from javascript. Everywhere I look, I'm just getting web-based answers and that won't help me. I'm working on a program that runs javascript while a machine is running, and I need this script to call a C++ function along the way, but can't figure out how. Any help? Even the most basic answer such as how to get a "Hello world" C++ funtion to run will be sufficient. Thanks!

where does the JavaScript run? in a browser or (like node.js) in the console?
if the JS runs in a browser, you can’t call a C++ function directly. you have to take a roundtrip and call a server script that runs the function for you. -
It runs in the console. Once a machine starts running, it executes a xxx.js file which processes the information. There is no indication on the computer that anything is happening at all. I just need this .js to call on some C++ functions.Comment

then it depends on the File System API that your JS host provides.
but even then, you can only call an app/script that runs the C++ for you. there is no way for JS to directly call another language’s function.Comment

How do I go about calling a script to execute the C++?Comment
-
that depends on the API that is available to JS.Comment
-
I am not aware of the API. I will have to do some digging.Comment
-
you may look at node.js, that’s also a console based JS implementation, so you might get some ideas.Comment

There is a funtion in the .js file that causes an arm to move and creates a database recording whther or not it runs in to something. Once the function completes, the robot software requires C++ to create a database and report that records pass/fail results if there were objects that it ran in to. I just need the javascript to call on the C++ scripting at the end of its routine to create the database and report. I don't know what all there is as far as API, other than I use a simple .js to execute commands for the robot and I need it to somehow activate a C++ script.Comment

asked the other way round, what application is running the JS?Comment
-
It's a machining program called Technomatix.Comment
-
then you would need to read the Technomatix documentation to find any info about an API that lets you communicate with other applications.Comment

I just returned from a meeting on the project, and it turns out that my boss has some code from the company that he held from me. He likes to make me work I guess. Thanks for the input!Comment
