Add nilsonlinux/rss-notifier plugin v1.0.0

[nilsonlinux]

Plugin

• Id: nilsonlinux/rss-notifier
• New plugin
• Update to an existing plugin (version bumped in plugin.toml)

What it does

RSS/Atom Notifier monitors RSS/Atom feeds in the background and notifies the user when new items are published.

Features:

• Widget on the bar showing unread count badge
• Panel with a scrollable list of feed items
• Native Noctalia notifications for new items
• Configurable refresh interval (1-1440 minutes)
• Customizable notification limit per cycle

External dependencies

None - The plugin is fully self-contained. It uses only Noctalia V5 native APIs for HTTP requests, XML/RSS parsing, system notifications, and state persistence.

Testing

• Tested on Niri
• Tested on Hyprland
• Tested on Sway
• Tested on another compositor:
• Noctalia version tested against: v5.0.0
• Plugin API level: 14

Test scenarios:

1. Added multiple feed URLs (BBC, TechCrunch, personal blogs)
2. Tested refresh intervals: 1, 5, 15, 30, 60 minutes
3. Validated RSS 2.0 and Atom feed parsing
4. Confirmed no duplicate notifications for already read items
5. Widget badge updates correctly on new items
6. Panel opens/closes with click and ESC key
7. Settings: add/remove URLs, toggle notifications, adjust limits

Checklist

• The directory name matches the part of id after the / in plugin.toml exactly.
• It ships plugin.toml, README.md, thumbnail.webp, and translations/en.json.
• README.md follows the
  README template, documents
  every entry id and dependency, and includes exact panel IPC commands and launcher prefixes where applicable.
• I created thumbnail.webp with the thumbnail generator.
• version follows semver and is bumped in this PR; plugin_api is the oldest API level this plugin requires.
• Every non-English translation in this PR uses a locale supported by Noctalia core, and I can read, write, and
  understand that language well enough to review and maintain it (no unreviewed machine/LLM translations).
• I did not edit catalog.toml; CI generates it.
• This PR touches exactly one plugin directory.

Code review attestation

Plugins run as trusted, unsandboxed Luau in the user's session. Confirm:

• The code is readable and not obfuscated, minified, or generated.
• It does not download and execute remote code.
• Every network call, filesystem write, and spawned process is something the description above accounts for.
• I have the right to publish this code under the license declared in plugin.toml.

1. blocking - rss-notifier/plugin.toml:10

The manifest declares no external dependencies, but rss-notifier/panel.luau:13 invokes xdg-open through noctalia.runAsync. The PR description also claims the plugin is self-contained. On systems without xdg-open, opening feed items fails.

Declare xdg-open in dependencies and document it under README requirements.

2. blocking - rss-notifier/README.md:41

The settings table documents feeds, refresh_interval, notify_new_items, and max_items_per_feed. None are manifest setting keys. The actual keys are feed_urls, refresh_minutes, notify_new, and max_notifications_per_cycle at rss-notifier/plugin.toml:12-43. The README also names the plugin "RSS Utils" while the manifest and thumbnail use "RSS/Atom Notifier".

Update the README to use the exact manifest name, setting keys, defaults, and behavior.

3. blocking - rss-notifier/translations/pt.json:2

The filename uses pt, while Noctalia's supported Portuguese locale code is pt-BR. Its dotted object keys also violate the repository's translation segment convention, unlike the nested structure in rss-notifier/translations/en.json:2.

Rename the locale to pt-BR.json and represent the translation keys as nested objects.
