RSS Feed (`starpunk/feeds/rss.py`) + +**Enhanced streaming RSS generation** with full Media RSS specification support: + +- Wrap size variants in `` elements +- Add `` for large/medium/small variants with attributes: + - `url`: Variant image URL + - `type`: MIME type + - `medium`: "image" + - `isDefault`: "true" for largest available variant + - `width`: Image width in pixels + - `height`: Image height in pixels + - `fileSize`: File size in bytes +- Add `` for thumb variant with dimensions +- Add `` for captions +- Implement isDefault fallback logic: large → medium → small +- Maintain backwards compatibility for media without variants (legacy fallback) + +**Example output** (with variants): +```xml + + + + + +Caption text +``` + +#### 2. JSON Feed (`starpunk/feeds/json_feed.py`) + +**Enhanced `_starpunk` extension** with media variant information: + +- Add `about` URL (configurable via `STARPUNK_ABOUT_URL` config) + - Default: `https://github.com/yourusername/starpunk` +- Add `media_variants` array when variants exist +- Each variant entry includes: + - `url`: Variant image URL + - `width`: Image width + - `height`: Image height + - `size_in_bytes`: File size + - `mime_type`: MIME type + +**Example output**: +```json +{ + "_starpunk": { + "permalink_path": "/note/test", + "word_count": 42, + "about": "https://github.com/yourusername/starpunk", + "media_variants": [ + { + "caption": "Test caption", + "variants": { + "thumb": { + "url": "https://example.com/media/2025/12/uuid_thumb.jpg", + "width": 150, + "height": 150, + "size_in_bytes": 3000 + }, + "small": { ... }, + "medium": { ... }, + "original": { ... } + } + } + ] + } +} +``` + +#### 3. ATOM Feed (`starpunk/feeds/atom.py`) + +**Enhanced enclosure links** with caption support: + +- Add `title` attribute to enclosure links for captions +- Keep simple (no variants in ATOM per design decision) + +**Example output**: +```xml + +``` + +#### 4. Test Updates (`tests/test_feeds_rss.py`) + +**Updated streaming media test** to match v1.4.0 behavior: + +- Changed `item.find("media:content")` to `item.find(".//media:content")` +- Now searches descendants (inside `media:group`) instead of direct children +- Updated docstring to reflect v1.4.0 variant support + +--- + +## Testing + +### Test Results + +All 44 feed tests pass: +``` +tests/test_feeds_rss.py .............
