What's the best way to embed Ruby as a scripting language in C++? Using ruby.h? SWIG? Something else? What I need is to expose some C++ objects to Ruby and have the Ruby interpreter evaluate scripts that access these objects. I don't care about extending Ruby or accessing it in C++.
I've found this article on embedding Ruby in C++, and while it's very useful, it's kinda old and I was wondering if there are any other resources on the subject (or open source implementations of similar engines).
swig is probablly the way to go..... but ruby doesnt embed too well......
if you want a language that embeds nicely into C++, try lua
Rice is looking very promising.
Ruby provides a very helpful README.EXT file. It has lots of information about how to extend Ruby, and convert between C & Ruby types.
There is also this excerpt from the pick axe book which pretty much covers the same thing.
In my case, when I added Ruby scripting to my application I decided against using swig, because my needs were very simple, and I didn't want to add yet another build dependency.
You might wish to check out tinyrb.
I've been working on Rarity (https://github.com/Plaristote/Rarity), which does two things:
- Generates Ruby bindings from a YML description of your C++ API
- Allows interaction with Ruby script in the most C++ fashion there is
I've solved a good deal of question (exception handling, garbage collection)... I haven't seen anywhere else the code generation that Rarity uses to make your bindings come to life. I also haven't seen any other lib that allows such an easy conversion between C++ and Ruby types.
I think Rarity's worth the shot ! And I'd be glad to have some feedback as well :) !
