Diego's PerlMonks page
I like Perl.
And one of the best sites to find Perl information,
code, and a very friendly community, is PerlMonks.org, where you can
find me as ZZamboni.
The PerlMonks modules
PerlMonks.org has many nice features, such as the chatbox
(where you can talk to other users), the Newest Nodes page (where
you can see which nodes you haven't read), it gives each user a
personal home page, etc.
Some time ago I wrote a quick script to grab the chatbox from
the web page and display the messages in the terminal. It quickly
evolved into a more sophisticated thing, becoming able to post
messages, check off personal messages, etc. It has benefited a lot
from the expertise of other Perl monks which have found it useful
and contributed code and ideas.
Later, I added a module to manage the Newest Nodes page, making
it possible to display it in a threaded form, mark messages as
read, etc. I also added a module for accessing user information,
such as your experience level.
So what started as simple module has grown into a family of
them, including PerlMonks::Chat, PerlMonks::NewestNodes and
PerlMonks::User. You can grab the whole thing here (also
in in zip format). See
below for the latest changes, or check the Change log. I'll add
documentation as I have time. You can check the included sample
programs (getchat.pl and pmpager.pl) to see how the modules are
used. The idea is for the PerlMonks modules to be used as a back
end for different user interfaces. See below for the list of
programs that use these modules.
You can also get the old
version (also in zip) of
the module, which includes only the PerlMonksChat class (doesn't
have the Newest Nodes or user information functionality, only
chatbox). I am no longer maintaining this version, and the new one
is backwards compatible, so you should no longer use the old
I have included a simple driver program in getchat.pl. It is very
crude, but it works. Simply type messages to send them (including
/msg), and type "/checkoff <number> ..." to check off
personal messages. You can also try the pmpager.pl program, which
can check your personal messages and either display them or email
them to you.
Of course, you are encouraged to use these modules in any way
you want, hack them, extend them, and send me back your changes or
suggestions. I'll use them if they are good, and give you proper
Programs that use PerlMonksChat.pm
These are the ones I know about. If you know some other, please send
me a link.
I have not tested most of these (except for the Perl/Tk Newest
Nodes and Chat clients, which I use regularly). If you have
problems with them, please contact their authors directly (unless
you are sure it's a problem with the PerlMonksChat.pm module).

- I have made several changes in the last month or so, but
haven't had time to announce them individually here. Check the
Change log for the
details. Major changes: PerlMonks::Chat can now expand
things of the form [id://node_id] to the node title, and
PerlMonks::NewestNodes now keeps persistent storage of the
state (read or unread) of the nodes.
- October 23 2000, 17:51
- Now PerlMonks::NewestNodes uses the new node query facility
available at perlmonks.org (I don't think it was announced
anywhere, but try
appending a comma-separated list of nodes after the last equal
sign) to properly do threading. So now if the parent of a node
in your Newest Nodes list is not in the list anymore, it
requests its information and inserts it into the thread, marking
it as already read. Also fixed a bug in the PerlMonks::login()
subroutine, thanks to Shendal.
- September 10, 12:45
- Wrote a new program called pmpager.pl, which gets your
personal messages and mails them or displays them to you. It
can optionally check them off if you want. This program is now
part of the 2.0 distribution, since it uses the
- September 8, 16:49
- The PerlMonks::NewestNodes module now can keep an internal
"read/unread" status for each node. I also added a
thread-visiting method and some other utility methods.
- September 7, 20:46
- In an effort to intelligently thread nodes whose parents
have already been marked as read, PerlMonks::NewestNodes now
creates "fake parents" for those nodes. Works to a certain
degree, but it's limited because it can only go up one
level. This is, if the "real parent" is child to another node,
the "fake parent" has no way of including this information,
which results in fragmented threads anyway. Also, there's no
way of knowing what the nodetype of the real parent is, so the
fake parent has to inherit its child's (except in the case of
- September 6, 18:31
- Changes to the PerlMonks::NewestNodes module: now each node
has a node_id field, and there are two new methods: clear_nn()
for marking the Newest Nodes as seen, and reset_nn() for
resetting the flag.
- September 5, 13:10
- The first version of the PerlMonksChat2.zip file was
missing a few files. If you got that file and the PerlMonks/
subdirectory is empty (or nonexistent), please download it
again. The PerlMonksChat2.tar.gz
file was not affected by this problem. Thanks to Shendal
for catching this.
- September 5, 1:06
- The first release of version 2.0 of
the PerlMonks modules is out. In this release, the
functionality has been split and reorganized among different
modules. Among other things, it provides now a threaded
interface to the Newest Nodes page. Check it out! Right now
it's in its very early stages, but it may be usable. Please
read the README and the ChangeLog in the package to get a
better idea of what has changed.
- September 2, 12:01
- The xp() subroutine in PerlMonksChat (and the /xp command in
getchat.pl) now gets the user that you are logged in as. Thanks
to vroom for adding that to the XML XP ticker!
- August 25, 2000, 11:51
- I worked around the problem with the HTML entities (below)
by using an ugly hack (converting [ to [ and < to [<],
which results in them being shown correctly, but as links), so
the new escape sequences can now be used. I hope this will be
fixed at the server end.
- August 25, 2000, 10:58
- Made send() convert \[, \], \< and \> to the
appropriate HTML entities before sending, so that it's easier
to type brackets (square and angle) in the chatbox.
Note: Please don't use these features yet. They don't
work properly in regular chatbox messages, only in personal
Also added two additional forms to the /co command: "/co all"
checks off all personal messages, and "/co last x" checks off
the last x messages (defaults to 1 if omitted).
- July 6,
- Made it escape some additional characters in the strings when
posting messages, because things like "+" and ";" were causing trouble.
- June 2, 2000, 16:42
- Added /xp command for displaying your XP, rank and voting
- June 2, 2000, 01:45
- Added /who command (alias /users) for listing other users
logged in. Also added proper support for "/me" in messages
(replacing it by the user name).
- June 1st, 2000, 14:30
- PerlMonksChat.pm now uses the new XML tickers implemented by
vroom. The external interface of the module hasn't changed, so
any programs built around it should not have any problems.
