Pipelining

tinyfeed is designed to work with basic pipelining. In its default behavior, tinyfeed expects a list of whitespace-separated feed URLs as arguments and will output HTML directly to stdout. It can take its input from stdin and use redirection for its output. tinyfeed also provides flags to use files directly. This provides a variety of options to manage I/O.

Given the following feeds.txt file:

# Software Engineering
https://lovergne.dev/rss.xml

# Cyber Security
https://words.filippo.io/rss/
https://feeds.feedburner.com/TroyHunt

# Frontend
https://tonsky.me/atom.xml
https://andy-bell.co.uk/feed.xml
https://www.htmhell.dev/feed.xml

Then the following commands are equivalent:

tinyfeed https://lovergne.dev/rss.xml \
    https://words.filippo.io/rss/ \
    https://feeds.feedburner.com/TroyHunt \
    https://tonsky.me/atom.xml \
    https://andy-bell.co.uk/feed.xml > index.html

cat feeds.txt | tinyfeed > index.html 

cat feeds.txt | tinyfeed -o index.html 

tinyfeed -i feeds.txt > index.html 

tinyfeed -i feeds.txt -o index.html

Which command you prefer will depend on your workflow but be aware that when using a redirection directly, like in the example, your HTML page will be blank while tinyfeed is processing and it will also stay blank if there is an error. To avoid that, use a temporary file or the --output flag:

# This fix the blank page issue
cat feeds | tinyfeed > /tmp/tinyfeed && mv /tmp/tinyfeed /path/to/index.html
# OR
cat feeds | tinyfeed -o /path/to/index.html
