How to find path of Perl modules used in a code

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

use TeamSite::CGI_lite;
use ecm::utils;
use ecm::css_utils;
use ecm::IValidOEncode;

If Perl modules are used as above in Perl code, where and how do I find path for these modules ?

I checked environment variables, but did not see anything there. I am posting list of environment variables here.

Try inspecting @INC from within Perl. See @INC and %INC in perlvar. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply]

Is "TeamSite" in your D:\iw-home\ dir as your path (`d:\iw-home\TeamSite\iw-perl\bin` suggests? If so, somewhere there you'll probably find the (possibly modified?) copy of Teamsite::CGI-Lite.pm that you're using. I don't see any reference to `ecm` in your path (or the other items you dumped), which makes me guess that choroba's suggestion above will show you where to find the other three modules you listed. If I've misconstrued your question or the logic needed to answer it, I offer my apologies to all those electrons which were inconvenienced by the creation of this post. Quis custodiet ipsos custodes.

If Perl modules are used as above in Perl code, where and how do I find path for these modules ? The perl search path is (mostly) not in the environment, it is built into perl. The only search path alternative in the environment is the variable PERL5LIB, whose content will be prepended to the search path list, which is in the perl special variable @INC. If my PERL5LIB contains `/home/shmem/perl/lib` then: `qwurx [shmem] ~ > perl -le 'print $INC[0]' /home/shmem/comp/perl/lib` [download] To get the path of a loaded module, convert all double colons to slashes and append ".pm" (e.g. `TeamSite::CGI_lite` becomes `TeamSite/CGI_lite.pm`), and lookup that key in the hash %INC. Examples (see perlrun for the command line switch `-M`): `qwurx [shmem] ~ > perl -MIO::Select -le 'print $INC{q(IO/Select.pm)}' /usr/lib/perl/5.14/IO/Select.pm qwurx [shmem] ~ > perl -My -le 'my $m = q(y.pm);print $INC{$m}' /home/shmem/comp/perl/lib/y.pm` [download] Note that the above examples are for Linux/UNIX/cygwin. Use double quotes in `cmd.exe` on Windows. update: added @INC code example, y.pm example perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply] [d/l] [select]

Use the perl debugger. Do perl -d <script>. Once in the debugger switch to the module: Defaria:perl -de 0 Loading DB routines from perl5db.pl version 1.33 Editor support available. Enter h or `h h' for help, or `man perldebug' for more help. main::(-e:1): 0 DB<1> use CGI; DB<2> f CGI Choosing /usr/share/perl/5.14/CGI/Util.pm matching `CGI': 1 package CGI::Util; 2 3: use strict; 4: use vars qw($VERSION @EXPORT_OK @ISA @A2E @E2A); 5: require Exporter; 6: @ISA = qw(Exporter); 7: @EXPORT_OK = qw(rearrange rearrange_header make_attributes unesc +ape escape 8 expires ebcdic2ascii ascii2ebcdic); 9 10: $VERSION = '3.51'; DB<3> [download] You'll notice the line starting with "Choosing". That tells you the path to the module that perl actually loaded.	[reply] [d/l]
