Note: When running on Microsoft Windows, the a.out below will be replaced by a.exe instead.
% pp hello.pl # Pack 'hello.pl' into executable 'a.out' % pp -o hello hello.pl # Pack 'hello.pl' into executable 'hello' # (or 'hello.exe' on Win32) % pp -o foo foo.pl bar.pl # Pack 'foo.pl' and 'bar.pl' into 'foo' % ./foo # Run 'foo.pl' inside 'foo' % mv foo bar; ./bar # Run 'bar.pl' inside 'foo' % mv bar baz; ./baz # Error: Can't open perl script "baz" % pp -p file # Creates a PAR file, 'a.par' % pp -o hello a.par # Pack 'a.par' to executable 'hello' % pp -S -o hello file # Combine the two steps above % pp -p -o out.par file # Creates 'out.par' from 'file' % pp -B -p -o out.par file # same as above, but bundles core modules # and removes any local paths from @INC % pp -P -o out.pl file # Creates 'out.pl' from 'file' % pp -B -p -o out.pl file # same as above, but bundles core modules # and removes any local paths from @INC # (-B is assumed when making executables) % pp -e "print 123" # Pack a one-liner into 'a.out' % pp -p -e "print 123" # Creates a PAR file 'a.par' % pp -P -e "print 123" # Creates a perl script 'a.pl' % pp -c hello # Check dependencies from "perl -c hello" % pp -x hello # Check dependencies from "perl hello" % pp -n -x hello # same as above, but skips static scanning % pp -I /foo hello # Extra include paths % pp -M Foo::Bar hello # Extra modules in the include path % pp -M abbrev.pl hello # Extra libraries in the include path % pp -X Foo::Bar hello # Exclude modules % pp -a data.txt hello # Additional data files % pp -r hello # Pack 'hello' into 'a.out', runs 'a.out' % pp -r hello a b c # Pack 'hello' into 'a.out', runs 'a.out' # with arguments 'a b c' % pp hello --log=c # Pack 'hello' into 'a.out', logs # messages into 'c' # Pack 'hello' into a console-less 'out.exe' with icon (Win32 only) % pp --gui --icon hello.ico -o out.exe hello % pp @file hello.pl # Pack 'hello.pl' but read _additional_ # options from file 'file'
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".
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
Since the command lines can become sufficiently long to reach the limits imposed by some shells, it is possible to have pp read some of its options from one or more text files. The basic usage is to just include an argument starting with an 'at' (@) sigil. This argument will be interpeted as a file to read options from. Mixing ordinary options and
@file options is possible. This is implemented using the Getopt::ArgvFile module, so read its documentation for advanced usage.
- -a, --addfile=FILE|DIR
Add an extra file into the package. If the file is a directory, recursively add all files inside that directory, with links turned into actual files.
By default, files are placed under
/inside the package with their original names. You may override this by appending the target filename after a
;, like this:
% pp -a "old_filename.txt;new_filename.txt" % pp -a "old_dirname;new_dirname"
You may specify
- -A, --addlist=FILE
Read a list of file/directory names from FILE, adding them into the package. Each line in FILE is taken as an argument to -a above.
You may specify
- -B, --bundle
Bundle core modules in the resulting package. This option is enabled by default, except when
Since PAR version 0.953, this also strips any local paths from the list of module search paths
@INCbefore running the contained script.
- -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.
- -c, --compile
perl -c inputfileto determine additonal run-time dependencies.
- -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.
- -e, --eval=STRING
Package a one-liner, much the same as
perl -e '...'
- -E, --evalfeature=STRING
Behaves just like
-e, except that it implicitly enables all optional features (in the main compilation unit) with Perl 5.10 and later. See feature.
- -x, --execute
perl inputfileto determine additonal run-time dependencies.
- -X, --exclude=MODULE
Exclude the given module from the dependency search path and from the package. If the given file is a zip or par or par executable, all the files in the given file (except MANIFEST, META.yml and script/*) will be excluded and the output file will "use" the given file at runtime.
- -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
If you are more serious about hiding your source code, you should have a look at Steve Hay's PAR::Filter::Crypto module. Make sure you understand the Filter::Crypto caveats!
- -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 (in .ico, .exe or .dll format) 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 joined by
=. You may specify
-Nmultiple times, or use
;to link several pairs.
For Win32 executables, these special
KEYnames are recognized:
Comments CompanyName FileDescription FileVersion InternalName LegalCopyright LegalTrademarks OriginalFilename ProductName ProductVersion
- -I, --lib=DIR
Add the given directory to the perl library file search path. May be specified multiple times.
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. May be specified multiple times.
- -L, --log=FILE
Log the output of packaging to a file rather than to stdout.
- -F, --modfilter=FILTER[=REGEX],
Filter included perl module(s) with a PAR::Filter subclass. You may specify multiple such filters. By default, the PodStrip filter is applied.
Since PAR 0.958, you can use an optional regular expression (REGEX above) to select the files in the archive which should be filtered. Example:
pp -o foo.exe -F Bleach=warnings\.pm$ foo.pl
This creates a binary executable foo.exe from foo.pl packaging all files as usual except for files ending in
warnings.pmwhich are filtered with PAR::Filter::Bleach.
- -M, --module=MODULE
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 MODULE has an extension that is not
.al, it will not be scanned for dependencies, and will be placed under
/lib/inside the PAR file. This use is deprecated -- consider using the -a option instead.
You may specify
- -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.
- -T, --tempcache
Set the program unique part of the cache directory name that is used if the program is run without -C. If not set, a hash of the executable is used.
- -v, --verbose[=NUMBER]
Increase verbosity of output; NUMBER is an integer from
3being the most verbose. Defaults to
1if specified without an argument. Alternatively, -vv sets verbose level to
2, and -vvv sets it to
- -V, --version
Display the version number and copyrights of this program.
- -z, --compress=NUMBER
Set zip compression level; NUMBER is an integer from
0= no compression,
9= max compression. Defaults to
6if -z is not used.
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
--dependent if you are willing to ship the shared library with the application, which can significantly reduce the executable size.
