NAME - Make and run Perl Archives 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: % -p # make a PAR dist under the current path % -p Foo-0.01 # assume unpacked CPAN dist in Foo-0.01/ To manipulate a PAR distribution: % -i Foo-0.01-i386-freebsd-5.8.0.par # install % -i # auto-appends archname + perlver % -i cpan://AUTRIJUS/PAR-0.74 # uses CPAN author directory % -u Foo-0.01-i386-freebsd-5.8.0.par # uninstall % -s Foo-0.01-i386-freebsd-5.8.0.par # sign % -v Foo-0.01-i386-freebsd-5.8.0.par # verify To use from ./foo.par: % -A./foo.par -MHello % -A./foo -MHello # the .par part is optional Same thing, but search foo.par in the @INC; % -Ifoo.par -MHello % -Ifoo -MHello # ditto Run or script/ from foo.par: % foo.par # looks for '' by default, # otherwise run '' To make a self-containing script containing a PAR file : % -O./ foo.par % ./ # 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: % -b -O./ foo.par % ./ # runs anywhere with core modules installed If you also wish to embed core modules along, use the -B flag instead: % -B -O./ foo.par % ./ # runs anywhere with the perl interpreter This is particularly useful when making stand-alone binary executables; see pp for details. DESCRIPTION
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 PAR is available for your platform, a binary version of will also be automatically installed as parl. You can use it to run .par files: # runs script/ in archive, uses its lib/* as libraries % parl myapp.par # runs or script/ in myapp.par % parl # also runs normal perl scripts However, if the .par archive contains either or script/, it is used instead: % parl myapp.par # runs, with '' 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 Stand-alone executable format The format for the stand-alone executable is simply concatenating the following elements: o The executable itself Either in plain-text ( or native executable format (parl or parl.exe). o Any number of embedded files These are typically used for bootstrapping PAR's 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 file's content (not compressed) o One PAR file This is just a zip file beginning with the magic string ""PK0304"". o Ending section The pre-computed cache name. A pack('Z40') string of the value of -T (--tempcache) or the hash of the file, followed by "CACHE". 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: ""12PAR.pm12"". SEE ALSO
