PAR::Dist - Create and manipulate PAR distributions
This document describes version 0.05 of PAR::Dist, released August 14, 2003.
As a shell command:
% perl -MPAR::Dist -eblib_to_par
In programs:
use PAR::Dist; my $dist = blib_to_par(); # make a PAR file using ./blib/ install_par($dist); # install it into the system uninstall_par($dist); # uninstall it from the system sign_par($dist); # sign it using Module::Signature verify_par($dist); # verify it using Module::Signature install_par("http://foo.com/DBI-1.37-MSWin32-5.8.0.par"); # works too install_par("http://foo.com/DBI-1.37"); # auto-appends archname + perlver install_par("cpan://AUTRIJUS/PAR-0.73"); # uses CPAN author directory
This module creates and manipulates PAR distributions. They are architecture-specific PAR files, containing everything under blib/ of CPAN distributions after their make or Build stage, a META.yml describing metadata of the original CPAN distribution, and a MANIFEST detailing all files within it. Digitally signed PAR distributions will also contain a SIGNATURE file.
make
Build
The naming convention for such distributions is:
$NAME-$VERSION-$ARCH-$PERL_VERSION.par
For example, PAR-Dist-0.01-i386-freebsd-5.8.0.par corresponds to the 0.01 release of PAR-Dist on CPAN, built for perl 5.8.0 running on i386-freebsd.
PAR-Dist-0.01-i386-freebsd-5.8.0.par
PAR-Dist
i386-freebsd
Five functions are exported by default. They can take either a hash of named arguments, a single argument (taken as $path by blib_to_par and $dist by other functions), or no arguments (in which case the first PAR file in the current directory is used).
$path
blib_to_par
$dist
Therefore, under a directory containing only a single test.par, all invocations below are equivalent:
% perl -MPAR::Dist -e"install_par( dist => 'test.par' )" % perl -MPAR::Dist -e"install_par( 'test.par' )" % perl -MPAR::Dist -einstall_par;
If $dist resembles a URL, LWP::Simple::mirror is called to mirror it locally under $ENV{PAR_TEMP} (or $TEMP/par/ if unspecified), and the function will act on the fetched local file instead. If the URL begins with cpan://AUTHOR/, it will be expanded automatically to the author's CPAN directory (e.g. http://www.cpan.org/modules/by-authors/id/A/AU/AUTHOR/).
LWP::Simple::mirror
$ENV{PAR_TEMP}
$TEMP/par/
cpan://AUTHOR/
http://www.cpan.org/modules/by-authors/id/A/AU/AUTHOR/
If $dist does not have a file extension beginning with a letter or underscore, a dash and $suffix ($ARCH-$PERL_VERSION.par by default) will be appended to it.
$suffix
Builds a PAR distribution from the blib/ subdirectory under $path, or under the current directory if unspecified. If blib/ does not exist, it automatically runs Build, make, Build.PL or Makefile.PL to create it.
Returns the filename or the generated PAR distribution.
Installs a PAR distribution into the system, using ExtUtils::Install::install_default.
ExtUtils::Install::install_default
Uninstalls all previously installed contents of a PAR distribution, using ExtUtils::Install::uninstall.
ExtUtils::Install::uninstall
Digitally sign a PAR distribution using gpg or Crypt::OpenPGP, via Module::Signature.
gpg
Verify the digital signature of a PAR distribution using gpg or Crypt::OpenPGP, via Module::Signature.
Returns a boolean value indicating whether verification passed; $! is set to the return code of Module::Signature::verify.
$!
Module::Signature::verify
