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.
