[SLUG] can ruby run perl/python libraries?
I'm thinking of learning Ruby - is there an easy way of running Perl and Python code/libraries from Ruby? I've googled and browsed manuals in Dymocks Library ^H^H^H Bookshop, can't seem to find an answer. Reason I ask is that I want to learn Ruby for Ruby on Rails, but there's so much good stuff in the existing Perl and Python libraries/cpan. (Yes I know about Python/Django, but Rails seems to have better doco/manuals at the moment). -- Sonia Hamilton.

I've googled and browsed manuals in Dymocks Library ^H^H^H Bookshop, can't seem to find an answer. on a quick google, this is the closest thing I could find for perl: http://www.yoshidam.net/perl_en.txt again - I've never used it and haven't read through it - but I guess it's a start for you :) Reason I ask is that I want to learn Ruby for Ruby on Rails, but there's so much good stuff in the existing Perl and Python libraries/cpan. true - though if you're using Rails I'd recommend you check if a library already exists in Rails first (a given, really). (Yes I know about Python/Django, but Rails seems to have better doco/manuals at the moment). Absolutely - and it's a dream to work with for web-app development. Besides-which, if you're using Rails, you at least know that most fo the Ruby community is behind Rails. Compare with the current joke that there are more web-development frameworks than keywords in Python ;) Cheers, Taryn -- Let there be lights! http://fiatlux.webcentre.co.nz/ -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

It's just considered normal because CPAN has ridiculously large number of just about _every_ type of module :) Adam K -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

This cropped up on the ruby talk list with regards perl in late September - http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/217173. Looking at the thread I'm not sure if there was a consensus - certainly no magical wrapping utility was mentioned when I last checked. You can run perl from C. And you can run/use C from ruby so if you're desperate you can bolt something together that way, maybe after a couple of beers. Some of the more common things in perl are replicated, sort of, in ruby. There is a CGI module and also dbi/dbd for instance, but the latter is nothing like as complete as perl. You might want to check out rubyforge.org, as well as the Pragmatic Programmer's Guide book which takes you through some of the more common modules which come with ruby. Reason I ask is that I want to learn Ruby for Ruby on Rails, but there's so much good stuff in the existing Perl and Python libraries/cpan. Definitely recommend you try rails out, and get used to its brand of MVC - you may not need whatever it is because rails comes with a lot of stuff but it takes time to exploit all of it (including some of its conventions). I usually install ruby from source (esp. on debian systems), and then set up rake and gems from source as well. Then use the gem utility to install rails and database stuff. Ruby gems will also handle multiple versions of rails. (Yes I know about Python/Django, but Rails seems to have better doco/manuals at the moment). -- Sonia Hamilton.

Looking at the thread I'm not sure if there was a consensus - certainly no magical wrapping utility was mentioned when I last checked. The only thing I can suggest at the moment is something that goes the other direction, one of the Inline:: modules (there was a bit of a fad relating to makeing Perl inline-embed anything a while back). http://search.cpan.org/~neilw/Inline-Ruby-0.02/lib/Inline/Ruby.pod The Inline::Ruby module would _seem_ to let you embed ruby code directly in your Perl. That _might_ be enough to get you going, but I doubt it, since I suspect what you really want is something like I want to call CPAN modules natively from Ruby That you don't get, although as was mentioned quite a number of the better and more venerable CPAN modules are gradually being cloned over to gems. To get something fairly robust I think you will need to wait for the Parrot/Perl6 stack, which _will_ allow native cross-language calls between Perl5/Perl6/Python/Ruby et al. But until that is more usable, there's no good answers I'm aware of.

Reason I ask is that I want to learn Ruby for Ruby on Rails, but there's so much good stuff in the existing Perl and Python libraries/cpan. Deviating from the stream of suggestions and pointers sent by others - I'd like to suggest you to reconsider that strategy - if you want to learn a new language then you better immerse yourself in its tools and way of thinking. It suspect that by looking for Ruby to wrap Perl/Python you are setting yourself a trap where you'll end up using Ruby/Rails as a thin shell in front of the real code. That's how you end up with people writing Shell Scripts the way they write C programs (e.g. not realizing they can treat the source code as data, as I've just seen on another linux mailing list) or, as happened to me when I tried to lean C++ after years of programming C - using C++ and ostreams/istreams and overloaded operators as glorified C instead of actually taking advantage of the new way of thinking the language encourages. I don't know Ruby and hardly know Python but I think the above is applicable for any new language and computing environment you want to get really comfortable with.
