A script to read usemod wiki's RSS feed and email all (not previously notified) recent changes to an email address. It keeps track of any changes it has already reported, so only reports 'new' recent changes, and sends no email at all if nothing has changed since last time it was run.
It's designed to be run from cron, at whatever interval you'd like to be kept informed of changes to your wiki.
It takes one optional argument - if present, this is the path to the configuration file to use; if absent, mail_usemod_changes will attempt to read the default configuration file (/usr/local/etc/mail_usemod_changes.conf).
The following is an example of an email it produces (with the To, From lines cut):
Subject: My Wiki Recent Changes
Home continue front page simplification 29 November 2003 12:21:38 -- Mk http://www.mywiki.notcom/wiki/wiki.pl?Home
AboutThisWiki front page tidyup 29 November 2003 12:20:20 ** Mk http://www.mywiki.notcom/wiki/wiki.pl?AboutThisWiki
Each page gets a paragraph, with the following format:
page name [ Description of change, if entered ] Time of change (**/--) Username URL to page
The significance of the revision is indicated by the **/-- indicator: ** for major revisions, -- for minor ones.
The URL is designed to be clickable from mail clients that automatically create symlinks to 'http://...' and trivially cut and pastable into a browser from those that do not. Mail clients that insist on angle brackets around URLs before making them clickable suck (since by so doing they make said URLs non-trivially cut and pastable) and are, therefore, not of interest.
/usr/local/etc/mail_usemod_changes.conf - the configuration file that will be used if one is not specified on the command line.
The configuration file consists of a number of key value pairs, one pair per line, with the keys and values separated by an equals sign '=' and any amount of whitespace. The following keys are required:
fetch_rss should be set to a command that will retrieve the RSS feed from the Wiki you are interested in and print it on standard output. For example:
fetch_rss = wget --quiet -O - http://wiki.somewhere.foo/wiki.pl?action=rss
This will fetch the default RSS feed from the somewhere.foo wiki. Much of the time, this will be exactly what you want.
You may find, however, that the default RSS feed is not to your taste; you may wish to be told about minor changes, or even every single revision (not just the most recent). In this case, use an ordinary browser to set UseModWiki's preferences and to obtain the cookie set by UseModWiki, and pass that to wget, as in the example below:
fetch_rss = wget --quiet --cookies=off --header=``Cookie: mywiki=rev&1&id&5001&randkey&123123123'' -O - http://wiki.somewhere.foo/wiki.pl?action=rss
