Manual Reference Pages - PAR.PL (1)
par.pl - Make and run Perl Archives
(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:
% par.pl -p # make a PAR dist under the current path
% par.pl -p Foo-0.01 # assume unpacked CPAN dist in Foo-0.01/
To manipulate a PAR distribution:
% par.pl -i Foo-0.01-i386-freebsd-5.8.0.par # install
% par.pl -i http://foo.com/Foo-0.01 # auto-appends archname + perlver
% par.pl -i cpan://AUTRIJUS/PAR-0.74 # uses CPAN author directory
% par.pl -u Foo-0.01-i386-freebsd-5.8.0.par # uninstall
% par.pl -s Foo-0.01-i386-freebsd-5.8.0.par # sign
% par.pl -v Foo-0.01-i386-freebsd-5.8.0.par # verify
To use Hello.pm from ./foo.par:
% par.pl -A./foo.par -MHello
% par.pl -A./foo -MHello # the .par part is optional
Same thing, but search foo.par in the @INC;
% par.pl -Ifoo.par -MHello
% par.pl -Ifoo -MHello # ditto
Run test.pl or script/test.pl from foo.par:
% par.pl foo.par test.pl # looks for main.pl by default,
# otherwise run test.pl
To make a self-containing script containing a PAR file :
% par.pl -O./foo.pl foo.par
% ./foo.pl test.pl # same as above
To embed the necessary non-core modules and shared objects for PARs
execution (like Zlib, IO, Cwd, etc), use the <B>-bB> flag:
% par.pl -b -O./foo.pl foo.par
% ./foo.pl test.pl # runs anywhere with core modules installed
If you also wish to embed core modules along, use the <B>-BB> flag
% par.pl -B -O./foo.pl foo.par
% ./foo.pl 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.
Binary PAR loader (parl)
If you have a C compiler, or a pre-built binary package of <B>PARB> is
available for your platform, a binary version of <B>par.plB> will also be
automatically installed as <B>parlB>. 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
% 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
Stand-alone executable format
The format for the stand-alone executable is simply concatenating the
The executable itself
Either in plain-text (par.pl) or native executable format (parl
Any number of embedded files
These are typically used for bootstrapping PARs various XS dependencies.
Each section contains:
The magic string FILE
Length of file name in pack(N) format plus 9
8 bytes of hex-encoded CRC32 of file content
A single slash (/)
The file name (without path)
File length in pack(N) format
The files content (not compressed)
One PAR file
This is just a zip file beginning with the magic string "PK\003\004".
The pre-computed cache name. A pack(Z40) string of the value of -T
(--tempcache) or the hash of the file, followed by \0CACHE. The hash
of the file is calculated with Digest::SHA, Digest::SHA1, or
Digest::MD5. If none of those modules is available, the mtime of
the file is used.
A pack(N) number of the total length of FILE and PAR sections,
followed by a 8-bytes magic string: "\012PAR.pm\012".
