NAME

Cac::ObjectScript - Source Filter for embedding ObjectScript expressions in Perl

SYNOPSIS

            

              
              
use Cac::ObjectScript;
my $a = 1;
$a = <? :a +1:>:
<:K ^foobar(:a):>
no Cac::ObjectScript; # disable source filter
            
          

DESCRIPTION

This module allows you to embed ObjectScript expressions enclosed in "<?" ... ":>" or ObjectScript statements in "<:" ... ":>"

The expressions are not evaluated, they are compiled into ObjectScript functions for everlasting speed.

You can use bind variables using :var notation.

Generated routines are named CPERLxxxxxxxxxxxxxxxxxxxxxxxxx where each x stands for a hexadecimal digit.

This is currently the md5sum (except last 7 digits) over the version of this module and the expression.

Anyway this may change (do not rely on that :), but I gurarantee that I only generate routines named "CPERL*".

If you just want to evaluate a Cache-String (i.e: a non constant expression) use CacEval $string of the Cac package.

You could also the following instead:

            

              
              
my $eval = "K GeorgeBush"; # this is a political statement :)
<: @:eval:>
            
          

but it doesn't look so fine :) If you got this, you've probably understand that module.

If you insist to write order-loops, try something like this:

            

              
              
my $a="";
do {
     $a = <?$order(^rOBJ(:a)):>;
     print "$a\n";
   } while length $a;

BUGS

            

              
              
Design: This Module creates a routine for every <[:?] ...  :> expression.
        It should create a single routine for each Perl source file.
        (The current design "eats" routine-buffers)
        I'm going to change that but that's not too high on my priority list.
        (Finding a girlfriend is :)
