C++ Reading code from file

[kirennia]

Lo guys

I was just wondering if any of you know how to read code from a file. For example, setup a virtual class in order to create an object without knowing whats inside the methods, then read the methods from an external, non-compiled class which contains c++ code?

Would I have to instead create some sort of mediary reading class and just read a file as data or is there an easier way to just implement non-compiled c++ code through a .exe?

I believe you have to create it. Open TTD is (I think) a perfect example. where .grf files add extra objects to the core game. The whole game is written in C++ and they have to code a lot. But I really don t have any experiance with it. Would like to learn though!

I'm just curious about it; doing my thesis atm, I'm trying to figure out the most productive way of implementing a plugin system, without sacrificing performance. It just seems logical to me... perhaps it's not the most cheat-proof of systems but being able to ... I don't know. For example, you want to recreate driving physics for a game... allow people to plugin their own driving models for acceleration, braking and steering. Whilst you're going to get a lot of crap, gems do emerge from plugin systems...just look at The Elder Scrolls.

Thanks for the example, I'll look into what can be done with that system and see if there's any logical way of doing it without spending too much time; it's very much a silver lining rather then a focus atm.

You need to use Reflection to extract Class, Methods and Events, ofc you need an high level of abstraction (you don't know anything after all).
Links are for c# and vb but you should get the whole thingie:

If you're not going to compile the C++ then you certainly don't want to try interpreting it yourself. C++ interpreters do exist but I can't think of good uses for them.

On a second read i got it wrong in fact :s
