Ruby bindings for Strophe 'code.stanziq.com/strophe/', a C library for writing XMPP clients. If all you need is a simple XMPP bot that react to message and presence notifications, you might be better off with XMPPBot 'github.com/flamontagne/xmppbot/', which is an implementation I wrote on top of StropheRuby.
Note that this gem is quite experimental and is not ready for production.
Strophe 'code.stanziq.com/strophe/' is a robust and well written C library that allows the developer to implement XMPP clients.
I wanted to be able to use the power of this library with the ruby syntax. I didn't use SWIG to generate the bindings for 2 reasons :
I wanted to learn how to write a C extension for ruby
I didn't like how SWIG generate gazilions of lines of code
My other project, XMPPBot, is an implementation of Strophe Ruby that allows the ruby developer to write a XMPP bot in a few lines of code.
gem install strophe_ruby
Currently no Support for TLS encryption
Cannot terminate the loop with CTRL-C
Socket disconnects after being inactive for too long
Cannot output log data to a file
