perl( function

perl(

SOURCE

)

The perl( function executes a perl program and returns the result (stdout).

Parameters

This function has one parameter:

source – Perl program (source code). Note: It is very convenient to use “pipe” delimiters for the source code parameter, for example |||code|||. This eliminates needing to worry about the delimiters appearing in the source code itself.

Description

This function executes Perl source code and returns the result. Here is a simple example.

perl({print "Hello World"."\n"."«timepattern(now(),"hh:mm:ss am/pm")»"}) ☞ Hello World
                                                                            4:47:26 PM

Panorama formulas can be embedded in the Perl source code using special tags. To embed a Panorama formula use

$«formula»$

The formulas are calculated in advance, then embedded into the source code as constants. For example, the formula $«2*3»$ will be embedded into the program as 6. The formula $«upper("hello world")»$ will be embedded as 'HELLO WORLD'.

In the case of text formulas any special characters will be encoded as necessary for a proper Perl constant. For example the formula $«{"}»$ will be embedded as '\x23'.

To embed a Panorama formula with no quotes or translation use

^«formula»^
