Did you tried with parsifal? Anyway.. My parser was simpler than all that xml-strict foo. So it worked too with corrupted and partially downloaded rss files.

I end up using wget and using local files with rss2html to process them. Depending on a library for this is imho not suckless

Config file for what? Specifying a list of feeds should not be in a config file. Maybe in a wrapper script or so.

Iirc A suckless way should be exporting a tsv where the first word of each line is the unix timestamp, so using sort -n should be more unix friendly.

At the end a feed reading should just comvert from various crappy atom/rss formats to an unified tsv output. The rest can be done with grep, sort and awk. Even the html output

I would suggest exporting json too. That will make templating work on client side and no need to do any templating system. Static html is good for lynx... Another option i would suggest is to put that template design in config.h

Yeah. I know that, but thats only useful if you use twitter in read only mode.

Can you specify filter for words? Grep will work here?

The workflow i would like to have with feeds is:

Fetch list of new stuff
Mark them as:
 - uninteresting (stroke, possibly add new filtering rules)
 - read later (have a separate list of urls to read when i have time)
 - mark as read/unread.
 - favorite (flag as imprtant thing)
 - show/hide all news from a single feed

I understand that this workflow shouldnt be handled by sfeed, because thats a frontend issue. But having html output does not allows me to do anything of that.

With json it would be easy to write a frontend like that easily in javascript ( blame me, but its fast and its everywhere). There's also a minimalist json parser named js0n that can do that from commandline too.

But probably people in this list would expect an awk friendly format instead of json. (tsv can be easily converted to json)
