NAME

PAR::Dist - Create and manipulate PAR distributions

SYNOPSIS

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://example.com/DBI-latest.par");   # this also works

DESCRIPTION

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.

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.

FUNCTIONS

Five functions are exported by default. They can take either a hash of named arguments, a single $dist argument, or no arguments (in which case the first PAR file in the current directory is used).

Therefore, under a directory containing only a single test.par, all invocations below are equivalent:

    % perl -MDist::PAR -e"install_par( dist => 'test.par' )"
    % perl -MDist::PAR -e"install_par( 'test.par' )"
    % perl -MDist::PAR -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.

blib_to_par

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.

install_par

Installs a PAR distribution into the system, using ExtUtils::Install::install_default.

uninstall_par

Uninstalls all previously installed contents of a PAR distribution, using ExtUtils::Install::uninstall.

sign_par

Digitally sign a PAR distribution using gpg or Crypt::OpenPGP, via Module::Signature.

verify_par

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.
