pp creates standalone executables from Perl programs, using the compressed packager provided by PAR, and dependency detection heuristics offered by Module::ScanDeps. Source files are compressed verbatim without compilation.
You may think of pp as "perlcc that works without hassle". :-)
A GUI interface is also available as the tkpp command.
It does not provide the compilation-step acceleration provided by perlcc (however, see -f below for byte-compiled, source-hiding techniques), but makes up for it with better reliability, smaller executable size, and full retrieval of original source code.
When a single input program is specified, the resulting executable will behave identically as that program. However, when multiple programs are packaged, the produced executable will run the one that has the same basename as
$0(i.e. the filename used to invoke it). If nothing matches, it dies with the error
Can't open perl script "$0".
On Microsoft Windows platforms, a.exe is used instead of a.out as the default executable name.
Options are available in a short form and a long form. For example, the three lines below are all equivalent:
% pp -o output.exe input.pl % pp --output output.exe input.pl % pp --output=output.exe input.pl
- -M, --add=MODULE|FILE
Add the specified module into the package, along with its dependencies. Also accepts filenames relative to the
-M Module::ScanDepsmeans the same thing as
If FILE does not have a
.alextension, it will not be scanned for dependencies, and will be placed under
/lib/inside the PAR file.
- -B, --bundle
Bundle core modules in the resulting package. This option is enabled by default, except when
- -C, --clean
Clean up temporary files extracted from the application at runtime. By default, these files are cached in the temporary directory; this allows the program to start up faster next time.
- -d, --dependent
Reduce the executable size by not including a copy of perl interpreter. Executables built this way will need a separate perl5x.dll or libperl.so to function correctly. This option is only available if perl is built as a shared library.
- -c, --compile
perl -c inputfileto determine additonal run-time dependencies.
- -e, --eval=STRING
Package a one-liner, much the same as
perl -e '...'
- -x, --execute
perl inputfileto determine additonal run-time dependencies.
- -X, --exclude=MODULE
Exclude the given module from the dependency search patch and from the package.
- -f, --filter=FILTER
Filter source script(s) with a PAR::Filter subclass. You may specify multiple such filters.
If you wish to hide the source code from casual prying, this will do:
% pp -f Bleach source.pl
Users with Perl 5.8.1 and above may also try out the experimental byte-compiling filter, which will strip away all comments and indents:
% pp -f Bytecode source.pl
- -g, --gui
Build an executable that does not have a console window. This option is ignored on non-MSWin32 platforms or when
- -h, --help
Show basic usage information.
- -i, --icon=FILE
Specify an icon file for the executable. This option is ignored on non-MSWin32 platforms or when
- -N, --info=KEY=VAL
Add additional information for the packed file, both in
META.ymland in the executable header (if applicable). The name/value pair is separated by
=. You may specify
For Win32 executables, these special
KEYnames are recognized:
Comments CompanyName FileDescription FileVersion InternalName LegalCopyright LegalTrademarks OriginalFilename ProductName ProductVersion
This feature is currently unimplemented.
- -I, --lib=DIR
Add the given directory to the perl library file search path.
Add the given shared library (a.k.a. shared object or DLL) into the packed file. Also accepts names under library paths; i.e.
-l ncursesmeans the same thing as
-l /usr/local/lib/libncurses.soin most Unixes.
- -L, --log=FILE
Log the output of packaging to a file rather than to stdout.
- -F, --modfilter=FILTER
Filter included perl module(s) with a PAR::Filter subclass. You may specify multiple such filters.
- -m, --multiarch
Build a multi-architecture PAR file. Implies -p.
- -n, --noscan
Skip the default static scanning altogether, using run-time dependencies from -c or -x exclusively.
- -o, --output=FILE
File name for the final packaged executable.
- -p, --par
Create PAR archives only; do not package to a standalone binary.
- -P, --perlscript
Create stand-alone perl script; do not package to a standalone binary.
- -r, --run
Run the resulting packaged script after packaging it.
- -S, --save
Do not delete generated PAR file after packaging.
- -s, --sign
Cryptographically sign the generated PAR or binary file using Module::Signature.
- -v, --verbose[=NUMBER]
Increase verbosity of output; NUMBER is an integer from
5being the most verbose. Defaults to
1if specified without an argument.
- -V, --version
Display the version number and copyrights of this program.
Command-line options (switches). Switches in this variable are taken as if they were on every pp command line.
Here are some recipes showing how to utilize pp to bundle source.pl with all its dependencies, on target machines with different expected settings:
- Stand-alone setup
% pp -o packed.exe source.pl # makes packed.exe # Now, deploy 'packed.exe' to target machine... $ packed.exe # run it
- Perl interpreter only, without core modules:
% pp -B -P -o packed.pl source.pl # makes packed.exe # Now, deploy 'packed.exe' to target machine... $ perl packed.pl # run it
- Perl with core module installed:
% pp -P -o packed.pl source.pl # makes packed.exe # Now, deploy 'packed.pl' to target machine... $ perl packed.pl # run it
- Perl with PAR.pm and its dependencies installed:
% pp -p source.pl # makes source.par % echo "use PAR 'source.par';" > packed.pl; % cat source.pl >> packed.pl; # makes packed.pl # Now, deploy 'source.par' and 'packed.pl' to target machine... $ perl packed.pl # run it
Note that even if your perl was built with a shared library, the 'Stand-alone setup' above will not need a separate perl5x.dll or libperl.so to function correctly. Use
--dependentif you are willing to ship the shared library with the application, which can significantly reduce the executable size.
Simon Cozens, Tom Christiansen and Edward Peschko for writing perlcc; this program try to mimic its interface as close as possible, and copied liberally from their code.
Jan Dubois for writing the exetype.pl utility, which has been partially adapted into the
Mattia Barbon for providing the
myldrbinary loader code.
