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.
