PAR::Filter(3) User Contributed Perl Documentation PAR::Filter(3)NAMEPAR::Filter - Input filter for PAR
SYNOPSIS
$code = 'use strict; print "Hello, World!\n";';
$ref = PAR::Filter->new('PodStrip', 'Bleach')->apply(\$code);
print $code; # pod-stripped and obfuscated code
print $$ref; # same thing
$ref = PAR::Filter->new('PodStrip', 'Bleach')->apply('file.pl');
print $$ref; # same thing, applied to file.pl
DESCRIPTION
Starting with PAR 0.76, "pp -f" takes a filter name, like "Bleach", and
invokes this module to transform the programs with PAR::Filter::Bleach.
Similarily, "pp -F Bleach" applies the Bleach filter to all included
modules.
It is possible to pass in multiple such filters, which are applied in
turn.
The output of each such filter is expected be semantically equivalent
to the input, although possibly obfuscated.
The default list of filters include:
· PAR::Filter::Bleach
The archetypical obfuscating filter.
· PAR::Filter::Obfuscate
Use B::Deobfuscate to strip away indents and comments, as well as
mangling variable names.
· PAR::Filter::PatchContent
Fix PAR-incompatible modules, applied to modules by default.
· PAR::Filter::PodStrip
Strip away POD sections, applied to modules by default.
· PAR::Filter::Bytecode
Use B::Bytecode to strip away indents and comments. This filter is
deprecated! For source hiding, have a look at PAR::Filter::Crypto
instead and make sure to read about its caveats.
