First a word of advice about managing perl especially in a production
environment. It is best to either use (and limit yourself to) perl and
perl modules as packaged for your distro OR do a handcrafted perl +
modules install from CPAN (not difficult). Mixing distro and CPAN
modules can be painful (think two dependency management systems
colliding mid-air) and causes unnecessary problems.
Perl comes with a lot of quite good documentation and perldoc is your
gateway to it (assuming you have it installed). A lot of what you can
find on the web or buy on books (eg. "Programming Perl") can be found in
the perl documentation. - the challenge is finding it :)
prompt> perldoc perl
provides a list of perl manual sections
which can again be accessed using perldoc.
perlintro - "Perl introduction for beginners".
prompt> perldoc perlintro
to read it.
prompt> perldoc -f $function
will return the perl documentation on internal function $function
(extracted from "perldoc perlfunc")
eg. perldoc -f map
prompt> perldoc -q "$phrase"
will use $phrase to search the perl FAQs and return sections which match
eg. perldoc -q hash
Once you know what a perl module is
prompt> "perldoc $module"
will let you read what documentation has been written into the module.
eg. perldoc Storable
are good places for useful hints, discussions, tips and tricks.
I agree with Michael about perl's CGI module. I would also look at DBI
if you want to use a database and give mod_perl a glance if you are
using apache. Beyond that take care. As you might expect the perl web
toolkit cat has been skinned many different and often incompatible ways
(eg. HTML::Mason, Template::Toolkit and HTML::Template).
If you want to avoid an off the shelf CMS as Michael suggests and do
more yourself then I would still review some perl CMS like
http://catalyst.perl.org/ to identify perl module sets which provide
desired functionality and behave nicely when used together.
