in thread About using rperl

What?

Inline::CPP writes xs modules for you , so you can call cpp functions from external cpp libraries without learning much xs

It comes with "tutorial"

RPerl converts Perl 5 source code into C++ source code

RPerl then converts the c++ code it created from perl 5 source code, into xs module, using Inline::CPP

There is no tutorial for explaining the RPerl way of wrapping an external library , ...GMPInteger_cpp.pm is as close to an example as you will find

...GMPInteger_cpp.pm is RPerl specific way of using Inline::CPP to call cpp functions from external cpp libraries ...

    If rperl is just a layer on top of Inline::CPP, then what is the advantage over patching B::Deparse to convert Perl Snippets to CPP?

    For instance code like the following 

    sub func :cpp int {
  my int ($a,$b) = @_;
  return $a+$b
}

    [download]

    is (after predefining :cpp and int) legal perl5 syntax and B::Deparse gets all necessary details.

    sub func {
    (my int ($a, $b)) = @_;
    return $a + $b;
}
use attributes ('main', sub {
    (my int ($a, $b)) = @_;
    return $a + $b;
}
, 'cpp', 'int');

    [download]

    So whats the extra value of rperl?

      You tell me?

      Is it not clear? I mean you must have at this point read everything there is to read about RPerl, the faq , docs , benchmarks / examples , jokes / original discussions about creating rperl...
