Re: About using rperl

I'm not an expert on rperl, but I think the answer to your third question should be obvious.

> Then, why not just write an XS-module?

XS modules are not easy to write. Being able to write high performance code in "pure" Perl should be an advantage.

Yes I agree! It would be great to see an example of how to call a `sub` in the shared library from regular Perl code.	[reply] [d/l]

It would be great to see an example of how to call a sub in the shared library I haven't seen such example of code, but I attended a talk by Will Braswell a few months ago, and asked whether it is feasible, and Will answered that it is possible. So you could have your CPU intensive nested loops or other computations in a RPerl module, and the rest in a regular Perl program. This looks very interesting to me, because it seems easier to write a RPerl module than an XS module.	[reply]

Please excuse my ignorance, but wouldn't this imply having two runtime environments for Perl communicating via sub calls? Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply]

This could be considered an example ... its a call to Inline::CPP ... https://metacpan.org/source/WBRASWELL/RPerl-5.000000/lib/RPerl/DataType/GMPInteger_cpp.pm `$RPerl::Inline::ARGS{libs} = '-lgmpxx -lgmp';` [download]	[reply] [d/l]

Yes I agree! It would be great to see an example of how to call a sub in the shared library from regular Perl code. Regular perl? See Inline::C, Re^19: Using STDIN after exec() with ActiveState Perl...	[reply]
