RSSt is a commandline tool that dump articles in followed feeds into offline files when run. It aims to be the tool for RSS what OfflineIMAP has been for IMAP.

See rsst --help for all options, but generally it's this workflow:

1. Create a config file in XDG_CONFIG_HOME/rsst/config.toml:

[setting]
output_format = "html"
output_dir = "~/documents/rsst/"

[source]
example = "https://example.com/rss.xml"

If output_dir is not given, the default one is "~/rsst". Sources listed in source section are the followed feeds, where example is the alias (used as the subdirectory name) and "https://example.com/rss.xml" is the feed file address.

2. Simply run rsst every time you want to check if there are new articles. RSSt will keep track of the last newest articles in $XDG_DATA_HOME/rsst, and incrementally retrieving new articles next time. You can sort files based on created/modified time to see what's new.

3. Retrieved articles will be in the given output_dir or ~/rsst. You can read them or parse them with whatever the way you want (web browser, for example).

Install it with whatever ways you like, for example:

https://github.com/quinoa42/rsst.git
cd rsst
cargo build --release

Then compiled executable will be located at target/release/rsst.
