Doing a search on the site revealed finding all modules used from a script HTH. Walking the road to enlightenment... I found a penguin and a camel on the way..... Fancy a yourname@perl.me.uk? Just ask!!!	[reply]

Thanks. I tried a similar search, unfortunately not with the word "finding". Gah!	[reply]

i don't know of a specific module, but the modules you use in a script are listet in %INC. try `perl -MData::Dumper -e'print Dumper \%INC'`	[reply] [d/l]

Can I get this to run before the script exits? I'm trying to debug a script, and don't know where it's failing, which is why I need the module.	[reply]

Sure, add something like: `use Data::Dumper; END { print Dumper \%INC }` [download] at the top of the program file. /J\	[reply] [d/l]

you can print out %INC at anny time you want to ;) modules that are importet by `use` are done in compile time, so they are in %INC right from the start. if you actualy use `require`, those modules should appear after you "required" them.	[reply] [d/l] [select]

The perl debugger is your friend (though not a very pretty one ;-) Check out perldebtut.(`perldoc perldebtut`) -Jim	[reply] [d/l]

This may get you more than you want, but does provide a lot of information. You can play with the -select an -ignore settings of Devel::Cover ... `mkdir /tmp/myscript_cover perl -MDevel::Cover=-db,/tmp/myscript_cover,-select,. /tmp/myscript.pl` [download] I ran this against: the following, and was able to see the used modules in the Devel::Cover output. `use strict; use File::Path; mkpath '/tmp/asdasd'; use Image::Magick; my $IMG_BLANK = Image::Magick->new();` [download]	[reply] [d/l] [select]
