rss-watch.pl

Perl script to monitor RSS feeds and execute scripts.

config

The config file is stored in ~/.config/rss-watch/config. Example configuration file:

[feed FeedName]
url = https://rss.example.com/
script = /home/user/script_to_exec.sh '$title' '$link' '$guid<isPermaLink>'

This will query the url specified by the url key for an RSS feed and execute the given script with the arguments title and link from the feed. Attributes can be selected by enclosing the attribue key in <> characters. For example, to select the isPermaLink attribute of the guid key, the selector would be $guid<isPermaLink>. Multiple script keys can be specified on new lines, which will all be executed. The key lastElemName can be defined to select the name of the field that will be used for last item detection. By default, this is pubDate. The key lastElemType can be used to change the type of value in lastElemName. By default this is timestring which means it is a time string value, which will be parsed into a number. The other possible value is timeint which is the same as timestring but it is already in a number, so no parsing happens.

Only new entries will be acted on. The file ~/.local/share/rss-watch/latest/FeedName will store the last guid value from the feed.

Use cron, or other tools to run this script periodically.
