Ability to call CompiledFunction from Callable about tengo HOT 5 CLOSED

This is one of the things that I wanted to implement earlier, but, invoking compiled functions from native Go code is a bit challenging. Maybe not in the near term, but, I will definitely revisit this feature in the future version. I know that's not what you wanted, but, you can always write map/reduce functions in Tengo and use them via modules, if that works.

Thanks, I'll give it a try. Perhaps I'll fork it and give it a go. I'll need to do that since "machine" is private to a Compiled.
Can I create a second machine, and run the function on that? how would I copy symbol table?

I'd say writing map/reduce functions in a module is better, but, if you want to experiment with running compiler/VM directly, my recommendation is to look at script.Script and script.Compiled code to see how they manage symbol table and global variables. More specifically this and this could be good starting points.

@kcsampson this functionality is now available in the tengo2 branch. The Callable interface and CallableFunc signatures have changed, so you might need to update your code to support that, but you will be able to call back to tengo code from go code provided you make the call from the same goroutine the VM is running on.

I'd like to know when this feature will be merged @mccolljr
