== mod_last_redis ==

Simple ejabberd module implementing xmpp's last activity extension XEP-0012
using a redis data store.

It is using the redo library from Jacob Vorreuter that can be found on github.

Tested with ejabberd 2.1.10.


=== Specifications ===

XEP-0012 specification can be found at http://xmpp.org/extensions/xep-0012.html


=== Limitations ===

As for mod_last_odbc, some web screen do not shows last activity properly
when using mod_last_redis. See https://support.process-one.net/browse/EJAB-6.

    On ubuntu::
   
      # aptitude install redis-server

      $ git clone https://github.com/sylane/mod_last_redis.git
      $ cd mod_last_redis
      $ EJABBERD_ROOT=$WHERE_EJABBERD_IS ./build()
  
 5. Copy mod_last_redis.beam to ejabberd ebin directory::
 
      $ cp ebin/mod_last_redis.beam $WHERE_EJABBERD_IS/ebin
