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 this.

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 requested

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
