Inline::Ruby 0.02

Inline::Ruby module can help you write Perl subroutines and classes in Ruby.

SYNOPSIS

print "9 + 16 = ", add(9, 16), "n";
print "9 - 16 = ", subtract(9, 16), "n";

use Inline Ruby;

__END__
__Ruby__

def add(a, b)
a + b
end

def subtract(a, b)
a - b
end

The Inline::Ruby module allows you to put Ruby source code directly "inline" in a Perl script or module. It sets up an in-process Ruby interpreter, runs your code, and then examines Rubys symbol table, looking for things to bind to Perl.
The process of interrogating the Ruby interpreter only occurs the first time you run your Ruby code. The namespace is cached, and subsequent calls use the cached version. Of course, your Ruby code must still be run every time your run the Perl script -- but Inline::Ruby already knows the results of running it.

Using the Inline::Ruby Module

Using Inline::Ruby will seem very similar to using any other Inline language, thanks to Inlines consistent look and feel.

This section will explain the different ways to use Inline::Ruby. For more details on Inline, see perldoc Inline.

Importing Functions

Using functions defined in Ruby is just like using Perl subs. You just supply the source code to Inline::Ruby, and then use them.

use Inline Ruby => <<END;
def doit
...
end
END

doit();

Importing Classes

If youre written a library in Ruby, its probably object-oriented. Binding Ruby classes to Perl is as easy as telling Ruby to import the class library.

use Inline Ruby;

my $obj = SomeClass->new;

__END__
__Ruby__

# Pretend SomeClass is defined in an external library
require SomeClass
