Of my Python and Perl tutorial at http://xahlee.org/perl-python/index.html

the most popular page is

“Sorting in Python and Perl”
http://xahlee.org/perl-python/sort_list.html

For example, in last week, that page is fetched 550 times.
The second most popular page, trails quite a distance. Here's the top
3 pages and their number of times fetched:

550 http://xahlee.org/perl-python/sort_list.html
341 http://xahlee.org/perl-python/system_calls.html
222 http://xahlee.org/perl-python/index.html

Note that the first 2 pages are far more popular than the entry page
the table of contents.

Apparently, and also verified by my web log, that people have
difficulty in using sort, and they find my pages thru web search
engines.

3.7: How do I cross-reference my Perl programs?

The B::Xref module can be used to generate cross-reference reports for
Perl programs.

perl -MO=Xref[,OPTIONS] scriptname.plx

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.

3.1: How do I do (anything)?

Have you looked at CPAN (see perlfaq2)? The chances are that someone has
already written a module that can solve your problem. Have you read the
appropriate manpages? Here's a brief index:

Greetings.

I'm using Compress::Zlib for the first time. I'm working with strings
are are ZLib-compressed but not fully RFC1950 compliant. I'm getting
some errors and, although I have it working, I know there has to be
a better way.

I started pretty simple:

3.12: Where can I get perl-mode for emacs?

Since Emacs version 19 patchlevel 22 or so, there have been both a
perl-mode.el and support for the Perl debugger built in. These should
come with the standard Emacs 19 distribution.

In the Perl source directory, you'll find a directory called "emacs",
which contains a cperl-mode that color-codes keywords, provides
context-sensitive help, and other nifty things.

Note that the perl-mode of emacs will have fits with "main'foo" (single
quote), and mess up the indentation and highlighting. You are probably
using "main::foo" in new Perl code anyway, so this shouldn't be an
issue.

I don't know how to follow links in an array (@links) at the bottom of
this script. Can anyone help me?

Hi,

I have declared my %%Properties but I get the following when I execute:

Global symbol "%%Properties" requires explicit package name at test.pl
line 62.
Global symbol "%%Properties" requires explicit package name at test.pl
line 67.
Global symbol "%%Properties" requires explicit package name at test.pl
line 69.
Global symbol "%%Properties" requires explicit package name at test.pl
line 71.
Global symbol "%%Properties" requires explicit package name at test.pl
line 72.
Global symbol "%%Properties" requires explicit package name at test.pl
line 73.

I have noted the lines in the code below.

Do I have to make some declaration within the sub?

cheers,

//mike

3.4: How do I find which modules are installed on my system?

You can use the ExtUtils::Installed module to show all installed
distributions, although it can take awhile to do its magic. The standard
library which comes with Perl just shows up as "Perl" (although you can
get those with Module::CoreList).

use ExtUtils::Installed;

my $inst = ExtUtils::Installed->new();
my @modules = $inst->modules();

If you want a list of all of the Perl module filenames, you can use
File::Find::Rule.

use File::Find::Rule;

my @files = File::Find::Rule->file()->name( '*.pm' )->in( @INC );
