=head1 NAME
parl - Binary PAR Loader
=head1 SYNOPSIS
(Please see L<pp> for convenient ways to make self-contained
executables, scripts or PAR archives from perl programs.)
To make a I<PAR distribution> from a CPAN module distribution:
% parl -p # make a PAR dist under the current path
% parl -p Foo-0.01 # assume unpacked CPAN dist in Foo-0.01/
To manipulate a I<PAR distribution>:
% parl -i Foo-0.01-i386-freebsd-5.8.0.par # install
% parl -i http://foo.com/Foo-0.01 # auto-appends archname + perlver
% parl -i cpan://AUTRIJUS/PAR-0.74 # uses CPAN author directory
% parl -u Foo-0.01-i386-freebsd-5.8.0.par # uninstall
% parl -s Foo-0.01-i386-freebsd-5.8.0.par # sign
% parl -v Foo-0.01-i386-freebsd-5.8.0.par # verify
To use F<Hello.pm> from F<./foo.par>:
% parl -A./foo.par -MHello
% parl -A./foo -MHello # the .par part is optional
Same thing, but search F<foo.par> in the F<@INC>;
% parl -Ifoo.par -MHello
% parl -Ifoo -MHello # ditto
Run F<test.pl> or F<script/test.pl> from F<foo.par>:
% parl foo.par test.pl # looks for 'main.pl' by default,
# otherwise run 'test.pl'
To make a self-containing executable containing a PAR file :
% parl -O./foo foo.par
% ./foo test.pl # same as above
To embed the necessary non-core modules and shared objects for PAR's
execution (like C<Zlib>, C<IO>, C<Cwd>, etc), use the B<-b> flag:
% parl -b -O./foo foo.par
% ./foo test.pl # runs anywhere with core modules installed
If you also wish to embed I<core> modules along, use the B<-B> flag
instead:
% parl -B -O./foo foo.par
% ./foo test.pl # runs anywhere with the perl interpreter
This is particularly useful when making stand-alone binary
executables; see L<pp> for details.
=head1 DESCRIPTION
This stand-alone command offers roughly the same feature as C<perl
-MPAR>, except that it takes the pre-loaded F<.par> files via
C<-Afoo.par> instead of C<-MPAR=foo.par>.
Additionally, it lets you convert a CPAN distribution to a PAR
distribution, as well as manipulate such distributions. For more
information about PAR distributions, see L<PAR::Dist>.
You can use it to run F<.par> files:
# runs script/run.pl in archive, uses its lib/* as libraries
% parl myapp.par run.pl # runs run.pl or script/run.pl in myapp.par
% parl otherapp.pl # also runs normal perl scripts
However, if the F<.par> archive contains either F<main.pl> or
F<script/main.pl>, it is used instead:
% parl myapp.par run.pl # runs main.pl, with 'run.pl' as @ARGV
Finally, the C<-O> option makes a stand-alone binary executable from a
PAR file:
% parl -B -Omyapp myapp.par
% ./myapp # run it anywhere without perl binaries
With the C<--par-options> flag, generated binaries can act as C<parl>
to pack new binaries:
% ./myapp --par-options -Omyap2 myapp.par # identical to ./myapp
% ./myapp --par-options -Omyap3 myap3.par # now with different PAR
For an explanation of stand-alone executable format, please see L<par.pl>.
