NAMEparl - Binary PAR Loader
SYNOPSIS(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 //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.
DESCRIPTIONThis 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.
