fatpack - Command line frontend for App::FatPacker
$ fatpack pack myscript.pl > myscript.packed.pl
A shortcut to do all the work of tracing, collecting packlists, extracting
modules in fatlib, then concatenating into a packed script - in one shot. If
you need more detailed controls for additional modules, use the following
commands separately (see "RECIPES").
$ fatpack trace [--to=trace-file|--to-stderr] [--use=MODULE]
Compiles myscript.pl (as in "perl -c") and writes out a trace file
containing every module require()
d during the compilation.
The trace file is called 'fatpacker.trace' by default; the --to option overrides
If you pass --to-stderr fatpack writes the trace to STDERR instead.
You cannot pass both --to and --to-stderr.
If the --use option specifies a module (or modules, if used multiple times)
those modules will be additionally included in the trace output.
$ fatpack packlists-for Module1 Module2 Module3
Searches your perl's @INC for .packlist files containing the .pm files for the
modules requested and emits a list of unique packlist files to STDOUT.
These packlists will, in a pure cpan-installation environment, be all non-core
distributions required for those modules.
Unfortunately most vendors strip the .packlist files so if you installed modules
via e.g. apt-get you may be missing those modules; installing your
dependencies into a local::lib first is the preferred workaround.
$ fatpack tree fatlib packlist1 packlist2 packlist3
Takes a list of packlist files and copies their contents into a tree at the
This tree should be sufficient to 'use lib' to make available all modules
provided by the distributions whose packlists were specified.
$ fatpack file
Recurses into the 'lib' and 'fatlib' directories and bundles all .pm files found
into a BEGIN block which adds a virtual @INC entry to load these files from
the bundled code rather than disk.
Current basic recipe for packing:
$ fatpack trace myscript.pl
$ fatpack packlists-for `cat fatpacker.trace` >packlists
$ fatpack tree `cat packlists`
$ fatpack file myscript.pl >myscript.packed.pl
