pwc-feeds VS reader

I like this pattern so much, I wrote an article about it; if you want to see what it looks like in real life, check this out.

It can also be used to build bookmarking / read later functionality similar to that of Tiny Tiny RSS; extracting content from arbitrary pages would be pretty helpful here.

To find out more, check out the GitHub repo and the docs, or give the tutorial a try.

Looking now through the Python API docs, I found the Quoting characters for use in search thing, which may come in handy for something I'm doing for my feed reader library (deduplicating articles). Not sure if I'll vendor it or add sqlite-utils as a new dependency, but it's good to know someone already solved this problem (I have a prototype, but I haven't really tested it).

I'm happy to announce version 2.0 of reader, a Python RSS / Atom / JSON feed reader library.

I'm also working on the 2.0 version of my feed reader library. The backwards compatibility break allows me to clean up a bunch of unnecessary code and fix some bad design decisions; I've deleted 250 lines of code until now, and it's very satisfying.

The exact same problems None has when it's not a valid value. None is different from the variable type, that's why you have Optional[VarType], which is an alias for Union[VarType, None]; you can model this in exactly the same way: Union[VarType, MissingType]; here's an example.

reader is a Python feed reader library – it offers all the high-level things you'd want when making a feed reader app/website, except the actual web app.
