Feature request: Tag-specific RSS feeds

[mwfogleman]

I'd like to add my blog to several topic-specific planets, but they require curated RSS feeds (e.g. the Clojure planet requires only Clojure-related posts). Could Cryogen support this?

[lacarmen]

This should definitely be possible. I could add something like :filtered-rss ["clojure"] to the config file and generate curated RSS feeds based on that along with the main RSS feed that's currently being generated.

Great, thanks Carmen!

If you are looking on and waiting for this to be a feature, you can use Yahoo Pipes to filter the default, inclusive RSS feed.

Should be done with version 0.1.12 of cryogen-core now :)

You would have to add :rss-filters ["clojure"] to your config.edn and of course the filters you list have to match the tags that you're using in your posts. The generated xml files will be named after the tags.

Wow! I did not expect same-day turnover-- thanks Carmen! Keep up the good work! 👍

Carmen,

Not sure how I didn't notice until now, but using this feature on my install generates RSS feeds with only the titles and the links.

https://mwfogleman.github.io/Emacs.xml

I did do a hairy upgrade, so it's possible I messed things up.

[lacarmen]

So I was using (get posts-by-tags filter) to get the posts for each filter, but it turns out posts-by-tags only contained the :uri and :title keys since I originally made that variable for making tag pages.

I've added in the :content key and tested so the filtered rss feeds to get generated properly now. Just bump up cryogen-core to 0.1.19 :)

Great, thanks so much Carmen.

I took a peek at the bugfix commit- neat to see how this functionality (and presumably much of Cryogen) is implemented with core functions like select-keys, get, reduce, etc. :D
