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]
myscript.pl
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 location.
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
