We need utility which runs as a daemon and uses a set of rules specifying information sources to be checked on a schedule. It is still in development and is based on the wikid.pl Perl script. It is currently just a single script containing snippets from daemonise.pl, wiki.pl, irc.pl, POP3.pl and server.pl. Eventually we plan to change those diverse functionalities from re-usable Perl code snippets to proper Perl modules which will be installed into the Perl environment from the Debian Post Install procedure.

Rules

The rules are defined as a list of items and can reside in a location available from any of the protocols it's set up to read from. Currently the rules must be bullet lists of 6 items as follows. Each set of these six items found in the rules resource will become an active task in the schedule. Our notifier rules are in Config:Notifier.

Rule Items

  • Schedule: pattern to be applied to localtime
  • Source: URL (file, http, mediawiki, pop3
  • Match: Regular expression to determine information to extract from source
  • Target: URL (file, mediawiki, mailto, irc)
  • Message: containing $n args
  • Comment: containing $n args (optional, used by some protocols like wiki or svn)

Example Uses

  • SVN changes sent to chat room
  • Changes to files appended to a log file
  • Changed files syncronised to wiki article
  • Changed articles written to files
  • Price of a product changing shows up in wiki changes
  • Checking search engine rankings of various keywords and phrases
