NAME
Perl::Strip - reduce file size by stripping whitespace, comments, pod
etc.
SYNOPSIS
use Perl::Strip;
DESCRIPTION
This module transforms perl sources into a more compact format. It does
this by removing most whitespace, comments, pod, and by some other
means.
The resulting code looks obfuscated, but perl (and the deparser) don't
have any problems with that. Depending on the source file you can expect
about 30-60% "compression".
The main target for this module is low-diskspace environments, such as
App::Staticperl, boot floppy/CDs/flash environments and so on.
See also the commandline utility perlstrip.
METHODS
The "Perl::Strip" class is a subclsass of PPI::Transform, and as such
inherits all of it's methods, even the ones not documented here.
my $transform = new Perl::Strip key => value...
Creates a new Perl::Strip transform object. It supports the
following parameters:
optimise_size => $bool
By default, this module optimises *compressability*, not raw
size. This switch changes that (and makes it slower).
keep_nl => $bool
By default, whitespace will either be stripped or replaced by a
space. If this option is enabled, then newlines will not be
removed. This has the advantage of keeping line number
information intact (e.g. for backtraces), but of course doesn't
compress as well.
cache => $path
Since this module can take a very long time (minutes for the
larger files in the perl distribution), it can utilise a cache
directory. The directory will be created if it doesn't exist,
and can be deleted at any time.
$perl = $transform->strip ($perl)
Strips the perl source in $perl and returns the stripped source.
