Most people who are actively developing using Perl are familiar with
sites for searching CPAN (the Comprehensive Perl Archive Network)
such as search.cpan.org
These sites provide a simple search bar where users can search for keywords
or key phrases, and find a list of results. These sites also feature
pages for the various CPAN distributions, the various authors, and the
individual pages of documentation inside the modules.
Recently, Andy Lester started the
CPAN” mailing list and wrote a
Perlbuzz post titled “Rethinking the interface to CPAN”, where he gave
the case that the current resources may be inadequate for the process
of selecting a module on CPAN. For a long time, there was an intermittent
discussion and some brain-storming, but very little code (if any) has been
written. This has all changed with
So what is CPANHQ? As documented in
and only wiki page it has so far (which I wrote a few days ago),
“CPANHQ aims to be a community-driven, meta-data-enhanced alternative to
such sites as http://search.cpan.org/
Currently, the functionality is very basic, but we have great ambitions.”
I learned about CPANHQ by overhearing a conversation on Freenode’s #perl
channel. I joined the effort, and made several enhancements to the
code. The functionality is still very basic.
Some of the plans and ideas we have for CPANHQ, which may be translated into
code in the future are:
The code is and will remain open-source, which makes it easy for people to
We plan to have most of the current features of search.cpan.org and
kobesearch.cpan.org including pages for authors, distributions, and individual
modules and their documentation.
The site aims to be more integrated than the many separate CPAN-related
sites today: search.cpan.org, CPAN Forum, AnnoCPAN, CPAN Ratings, CPANTS,
CPAN Dependencies, etc. By putting everything under one roof, we can provide
a better user experience than the many sites with very loose integration.
We plan to enhance the site based on meta-data as provided by both the module
authors (in the META.yml file and the users of the site.
For example, we have already added support for the META.yml’s
keywords which allow authors to tag modules, and we plan to support
CPANHQ will be very community-driven. People would be able to open user
accounts there, which will allow them to contribute content to the site,
such as tags/labels, comments, wiki pages, chatter, etc.
The CPANHQ wiki page
contains more ideas and insights. Like I said, the current functionality is
incredibly basic, but we hope that with enough help, time and dedication,
we can create an attractive and engaging interface to CPAN, to make
finding a module on CPAN faster, easier and more fun.
