Calling a command line script from PB program

[ac667788]

Hi All,
I would like to call a command line ruby script from within a PB program, but I am unsure of how to do it. Would you use the console functions or program functions? What would be the best way of passing data back?
Thanks

The easy way would be to use runprogram() with the commandline ruby interpreter. However passing data back and forth eitehr had to be over a shared memory area or a database ( both ways have their tricky side about synchronization ).

The better way would be to use the ruby.dll (which you also can ship with your program - unaltered or with source ofc since its GPLed ) - the dll can be called from purebasic and basically gives you the functionality to call your own ruby scripts from file / memory from inside pb. Personally i havent done this yet with ruby ( i tried the similar with php - which worked ). Personally i now use Dracscript as scripting language as its written in PB and pretty easy to extend.

In case you havent seen that one yet check out: http://www.purebasic.fr/english/viewtopic.php?t=20312

Whats it for btw ? Writing your own webserver ? =)

Thalius,
Thanks for the good insight, I will go ahead a check out ruby.dll and let you know how it goes.

I am trying to make a personalized stock analysis system and I want to take advantage of a ruby script that can download stock data from Yahoo Finance.

Thalius,
... take advantage of a ruby script that can download stock data from Yahoo Finance.

hmmm - depending what format that data is ( some use RSS which is pretty common ) and if or not https then this would be pretty easy also to write in a simple set of PB Procedures ( faster too ) - and if its about pluggability then you could just epxort this as a dll ( much smaller and more compact than distributing the whole ruby incl your script etc =)
