C++ interpreter

[PengYu.UT]

Hi,

Once C++ program use a lot of metaprogramming, the compilation of the
code takes a lot of time. I'm wondering if there is any C++ interpreter
available such that I don't have to wait for too long to run the binary
code.

Thanks,
Peng

I would guess that any interpreters cannot evaluate templates as
correctly as a real compiler. And metaprogramming is supposed to be about
speed of execution, so you would lose that, too.

Have you followed sane coding practices, so each recompile is as short as
possible?

Templates constitute a Turing complete sublanguage (macro-language)
within C++. In that sense, the template evaluation machanism is the
interpreter.

You may try
http://www.softintegration.com/
whether it will work with your code.

Also CINT interpreter exists
http://root.cern.ch/root/CintInterpreter.html
but it is not very string in dealing with metaprograms.

My feeling is that no interpreter will be significantly
faster than a compiler, just because most of the
work is spent in front-end and all this needs to
be made during interpretation.
