alfn (Aggregated Latest Filtered News) is a great little tool to create your own RSS feed about only the stuff you´re really interested in! Just configure it with the feeds to watch and what to watch for, and just sit back and wait for the updates. Oh, and it supports hotreloading configuration changes!
The easiest way to install the binary is via go get:
go get github.com/bep/alfnThen run it with the -h flag to see the options available:
alfn -h
alfn looks, by default, for configuration named either config.toml, config.yaml or config.json in either $HOME/.alfn or /etc/alfn/. The config file to use can also be set in the --config flag.
Below is an imaginary liverpool-feed.toml -- a feed about the Premier League football club Liverpool:
