JCPP

I know it wont attract lots of fan but I have to try :)
What if we incorporate such a project https://github.com/charb/jcpp within Qt ?
I come from Java world and tried to do some C++. Qt was the best stuff out there, better than Boost.
But I still find missing stuff, so I wrote that project to fill the gaps between Java world and C++.
What do you think ?
If you are a C++ purist, you would like to kill me, but if you try to think differently you might like what I did ...

Hi and welcome to devnet,

Do you mean your project to be an alternative to JNI ?

chacha

No, not really. JNI does the bridge between the JVM/Java code and C++. So in the same process where you use JNI you have a JVM running and your C/C++ code.
My project is developed using 100% C++ code and doesn't use any JNI code. The running process that will contain the code that I developed doesn't run any JVM and doesn't load any JDK class.
For every Java class that you have withing the JDK I developed its equivalent in C++ using pure C++ library, and added the same features that you can find in JAVA : introspection, serialization, threading, ... and with the same API that you can find in Java.
Hope it is clear

Hi, I can appreciate the obviously large amount of effort you put into this but what exactly is the purpose?

If I understand correctly it basically allows to write Java (or rather Java-like) code in C++. As such the potential target group would be people migrating from Java to C++, but this transition usually takes a month or two after which the person either starts to love C++ for all the low level control it gives (like pointers) or hates its guts and grumpily goes back to Java.

If you're just gonna write Java in C++... why not simply stay with Java?
I don't see any sustainable value in it. Sorta like what C++/CLI tried to do with C++ and .Net and that didn't go so well.

But don't get me wrong, I wish you well and might totally missed the point. It's late here ;)

Hi thank you for your reply.

The target is quite the opposite that you are describing. Developers and projects that are using C++ in huge project like myself. I come from a Java world and have a huge project to do in C++. I agree with you that the language allow very powerful low level control, but I dont need that 99% of the time.
With time I found that most of the Java open source projects are more readable than the rare ones in C++ (sorry for the fans and all people working to make it different).
Plus in my case, I had the very famous issue about serialization cross language. It is a way to solve it. Of course there are lots of projects that try to solve the problem, but I found with this way I wont limit the objects that I use in Java or in C++

If we have all our projects in Java, this project is useless.
If we have all our projects in C++, it might be useful for the following:

we need to interact with Java objects via RPC for example. It is the best way without any limitations
we need rich open sources or features like the ones we have in Java

Most of my experience was spent in company with huge legacy code developed in C++ that can't easily be redeveloped in Java.
