Hi,


I am working on a project translates OO programs to procedural
programs, such as translating C++ to C and the like. I hope this
effort can be spreaded out to other langs, so I am working on to
abstract the common issues of doing so. I know there is a pinoneer
attempt is C Front which produce C++ programs via a C compiler, I want
to have a look on that, but still cannot find it now, anyone can
suggest this to me?


My approach is just to rename the methods with the instance name so
that they can be placed in a single source file and then be compiled
later by the procedural lang compiler. For instance,


class A{
B b;
void method(){
b.run();
}
}


class B{
void run(){
...
}
}


If the main rountine is
void main(){
A a = new A();
a.method();
}


then the program would be translated to
void a_method(){
a_b_run();
}


void a_b_run(){
...
}
But I feel it is really not an adaptable way when dealing with
declaration inside iterations whose number of iteration is not sure,
means that we cannot change the names of the reference inside the
iteration.
for(...){
A a = new A();
}
  So far I am a little bit frustrated on this approach, anyone has
better idea? Pls share your thoughts, thank you!
