parl - Binary PAR Loader
(Please see pp for convenient ways to make self-contained executables, scripts or PAR archives from perl programs.)
To make a 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 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 Hello.pm from ./foo.par:
% parl -A./foo.par -MHello
% parl -A./foo -MHello # the .par part is optional
Same thing, but search foo.par in the @INC;
% parl -Ifoo.par -MHello
% parl -Ifoo -MHello # ditto
Run test.pl or script/test.pl from 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 "Zlib", "IO", "Cwd", etc), use the -b flag:
% parl -b -O./foo foo.par
% ./foo test.pl # runs anywhere with core modules installed
If you also wish to embed core modules along, use the -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 pp for details.
This stand-alone command offers roughly the same feature as "perl -MPAR", except that it takes the pre-loaded .par files via "-Afoo.par" instead of "-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 PAR::Dist.
You can use it to run .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 .par archive contains either main.pl or script/main.pl, it is used instead:
% parl myapp.par run.pl # runs main.pl, with 'run.pl' as @ARGV
Finally, the "-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 "--par-options" flag, generated binaries can act as "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 par.pl.
