“XMPP: The Definitive Guide” Code Examples

2009-07-13T00:00:00+02:00

Although the primary focus of XMPP: The Definitive Guide is explaning the XMPP protocol and all its extensions through text and illustrations, we also included a few Python code examples to help people get started with implementing their own ideas. In fact, we devoted a whole chapter to building an XMPP application, starting out with a simple bot implementation, but gradually extending the application into a full server component. For people who want to try this out for themselves, we’re releasing the source code of all code examples, including a simple echo bot, and different variants of the CheshiR microblogging platform XMPP interface.

All examples are built using the lightweight SleekXMPP Python XMPP library. In fact, SleekXMPP is so lightweight that we included a version in the source bundle, making it even easier to get started implementing your own bots and components.

Do bear in mind that these examples only serve illustrative purposes for the book, so don’t expect very robust code. Although making this code fail-safe is not really our primary goal (since that would involve a lot of code that would only distract the reader), we do welcome bug reports or fixes.

The code examples are available as a source package, or directly from the Git repository (mirrored on GitHub). We will soon put a link to the package on the book’s webpage.

AtoMail 0.7 released

2007-07-29T00:00:00+02:00

There have been some small bug fixes since the previous announcement of AtoMail, so it’s time for another snapshot.

Since the script only is receiving minor tweaks and bugfixes lately, it is probably advisable to keep track of the Git development version from now on.

SVNFeed: Monitoring Subversion repositories with RSS

2006-12-04T00:00:00+01:00

If it wasn’t clear by now, I’m pretty addicted to RSS. Some people disagree, and see RSS as evil because of the extra traffic that active polling of the feeds introduces. To me, it’s the easiest way of publishing news, anyone can set up a feed on about any host, and because of the polling nature it allows for easier scripting than other solutions. Besides, with web-based solutions like Google Reader, the extra traffic can be shared across many users anyway.

The only frustration I am left with is that not every webpage or software package that interests me has an RSS feed. I wrote AtoMail to have an RSS feed of projects (or webpages) that have mailinglists instead of RSS feeds. In addition to this script, I just released a script called SVNFeed, which I use to monitor Subversion activity of projects that don’t have an RSS-enabled Subversion Web interface. By monitoring the tags dir of a project, I can even get a more coarse grained granularity of updates, mostly up to the release.

Both scripts might be consolidated in the future, possibly together with even more RSS generation scripts I have lying around ;–)

AtoMail 0.4 released

2006-11-15T00:00:00+01:00

Shortly after the initial version and a few subsequent bugfix versions, AtoMail 0.4 is now available. This release allows you to retrieve mail from various different sources: stdin, local mailboxes (in different formats), POP3 (+SSL), IMAP4(+SSL), and NNTP usenet newsgroups.

AtoMail 0.1 released

2006-11-08T00:00:00+01:00

AtoMail is a Python script that converts mail into an RSS feed. This is for example useful for tracking announcement mailinglists in your favorite RSS reader, if no classic RSS feed is available.

This script is aimed at people who do not want to make use of services such as mail2rss.org (e.g. in order to have more control, for more reliability, privacy, …), or do not have the resources to set up a service such as mail2rss.
