PP(1) User Contributed Perl Documentation PP(1)NAMEpp - Perl Packager
SYNOPSISpp [ -BILMTSVXdeghilmoprsvz ] [ parfile | scriptfile ]...
EXAMPLES
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
% 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
# (-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'
DESCRIPTIONpp creates standalone executables from Perl programs, using the com-
pressed 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 tech-
niques), but makes up for it with better reliability, smaller exe-
cutable 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
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 lim-
its 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::Argv-
File 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 tar-
get filename after a ";", like this:
% pp-a "old_filename.txt;new_filename.txt"
% pp-a "old_dirname;new_dirname"
You may specify "-a" multiple times.
-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 "-A" multiple times.
-B, --bundle
Bundle core modules in the resulting package. This option is
enabled by default, except when "-p" or "-P" is specified.
-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
Run "perl -c inputfile" to determine additonal run-time dependen-
cies.
-d, --dependent
Reduce the executable size by not including a copy of perl inter-
preter. 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 '...'"
-x, --execute
Run "perl inputfile" to 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 spec-
ify 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 "-p" is speci-
fied.
-h, --help
Show basic usage information.
-i, --icon=FILE
Specify an icon file (in .ico, .exe or .dll format) for the exe-
cutable. This option is ignored on non-MSWin32 platforms or when
"-p" is specified.
-N, --info=KEY=VAL
Add additional information for the packed file, both in "META.yml"
and in the executable header (if applicable). The name/value pair
is joined by "=". You may specify "-N" multiple times, or use ";"
to link several pairs.
For Win32 executables, these special "KEY" names 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.
-l, --link=FILE|LIBRARY
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
ncurses" means the same thing as "-l libncurses.so" or "-l
/usr/local/lib/libncurses.so" in 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
Filter included perl module(s) with a PAR::Filter subclass. You
may specify multiple such filters.
-M, --module=MODULE
Add the specified module into the package, along with its dependen-
cies. Also accepts filenames relative to the @INC path; i.e. "-M
Module::ScanDeps" means the same thing as "-M Module/ScanDeps.pm".
If MODULE has an extension that is not ".pm"/".ix"/".al", it will
not be scanned for dependencies, and will be placed under "/"
instead of "/lib/" inside the PAR file. This use is deprecated --
consider using the -a option instead.
You may specify "-M" multiple times.
-m, --multiarch
Build a multi-architecture PAR file. Implies -p.
-n, --noscan
Skip the default static scanning altogether, using run-time depen-
dencies 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 Mod-
ule::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 1 to 3, 3
being the most verbose. Defaults to 1 if specified without an
argument. Alternatively, -vv sets verbose level to 2, and -vvv
sets it to 3.
-V, --version
Display the version number and copyrights of this program.
-z, --compress=NUMBER
Set zip compression level; NUMBER is an integer from 0 to 9, 0 = no
compression, 9 = max compression. Defaults to 6 if -z is not used.
ENVIRONMENT
PP_OPTS
Command-line options (switches). Switches in this variable are
taken as if they were on every pp command line.
NOTES
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 signifi-
cantly reduce the executable size.
