[ move all devel chit chat to PerlSamplePluginDev ]

This plugin nicely formats a Perl piece of code, together with its STDOUT and STDERR outputs.

• To avoid unproper usage it executes the Perl code in a Safe compartment.

His brother is the TWiki:Main.PrologSamplePlugin

TODO:

• Apply a timeout to the perl execution (spawn a delayed kill process)
• Limit the output size (disk quota?)
• Use a random generated file for the output/stderr

Usage example

 
%PERLSAMPLE{ 
print "hello world!"; 
}%  

1

print "hello world!";

1 

 1: hello world! 

Settings

• One line description, is shown in the TextFormattingRules topic:
  • Set SHORTDESCRIPTION = This plugin nicely formats a Perl piece of code, together with its STDOUT and STDERR outputs.

Installation

• Install the Safe Perl module (included since perl 5.005_04)
• Unzip the PerlSamplePlugin.zip file in your TWiki installation directory.
• double check that bin/perl_stdout.tmp and bin/perl_stderr.tmp are writable by the Apache user.

If the installation is correct you will see a nice table showing the code, its value and stdout/stderr near the example.
