par::filter::bytecode
PAR::Filter::Bytecode(3) User Contributed Perl Documentation PAR::Filter::Bytecode(3)NAME
PAR::Filter::Bytecode - Bytecode filter
SYNOPSIS
PAR::Filter::Bytecode->apply($code); # transforms $code
DESCRIPTION
This filter is deprecated. The B::Bytecode code has been removed from the newest development series of perl and will not be included in
perl 5.10 any more. Please have a look at Steve Hay's PAR::Filter::Crypto module if you want to hide your sources.
This filter uses B::Bytecode to turn the script into comment-free, architecture-specific Perl bytecode, and uses ByteLoader to load back on
execution.
For pp users, please add an extra -M option, like this:
pp -f Bytecode -M ByteLoader
Otherwise, the implicit dependency on ByteLoader will not be detected.
CAVEATS
This backend exhibits all bugs listed in B::Bytecode, and then some.
Bytecode support is considered to be extremely fragile on Perl versions earlier than 5.8.1, and is still far from robust (as of this
writing).
Bytecode is not supported by perl 5.9 and later.
