PAR::Packer exclude modules

Microcebus has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

I build standalone executables of my Perl scripts using the PAR::Packer. Everything works fine, but the size of the executable file becomes very large (~14MB). I know there is an exclude option -X but how can I know which of the modules I can exclude?

Is there a possibility to list all modules NOT needed for a certain script? Or maybe to list all modules within my PERL and all mudules needed by the script in question?

Thanks for your wisdom.

Take a look at The resulting files are huge! How can I reduce the size of the output file? from the PAR FAQ.	[reply]

You could make a packed .pl that relies on the target machine having a perl interpreter and core modules: `pp -P -o out.pl script.pl` [download] Then unzip it: `unzip -l out.pl \| sort -n` [download] I tried it on a 370 byte script, and the result was a packed .pl that was 272 bytes, smaller than the original. Cool!	[reply] [d/l] [select]

but how can I know which of the modules I can exclude You can't :) You could Try It To See but you'll be disappointed Is there a possibility to list all modules NOT needed for a certain script? Yes, subtract the list of modules required, from the list of installed modules or cpan modules Super Search	[reply]
