is there a way to add a bar for the topic, right now only search for tech news but if i
want videogames or cience, is it possible?
/btwis there a way to add a bar for the topic, right now only search for tech news but if i
want videogames or cience, is it possible?
Yes, totally possible. The Hacker News API has fixed categories (topstories, askstories,
etc.) but it's always tech-focused. To get other topics like videogames or science you'd
need to switch news sources.
The cleanest approach would be a source/category bar (similar to the tab bar already in the
app) where each entry points to a different RSS feed or API:
[ HN Tech ] [ Games ] [ Science ] [ Programming ] [ World ]
Good free sources that need no API key:
┌─────────────┬──────────────────────┬──────────┐
│ Category │ Source │ Type │
├─────────────┼──────────────────────┼──────────┤
│ Tech │ Hacker News API │ JSON API │
├─────────────┼──────────────────────┼──────────┤
│ Games │ Reddit r/gaming │ RSS feed │
├─────────────┼──────────────────────┼──────────┤
│ Science │ Reddit r/science │ RSS feed │
├─────────────┼──────────────────────┼──────────┤
│ Programming │ Reddit r/programming │ RSS feed │
├─────────────┼──────────────────────┼──────────┤
│ General │ BBC News │ RSS feed │
├─────────────┼──────────────────────┼──────────┤
│ Science │ NASA │ RSS feed │
└─────────────┴──────────────────────┴──────────┘
Reddit RSS feeds are simply https://www.reddit.com/r/gaming.rss — they return XML with
title, URL, score, and author, very similar to what the app already displays.
The main work to implement it:
1. Add an rss or quick-xml crate to parse XML feeds
2. Define a Source enum with a URL per category
3. Add a horizontal source bar (like the current tab bar) at the top, navigated with ←/→ or
number keys
4. When you switch source, fetch and parse that feed instead of the HN API
5. The Story struct stays the same — just map RSS fields into it
The UI and content display code wouldn't need to change at all since everything downstream
just works with Vec<Story>.
