[BlueskyBridge] Image carousel is unsupported

[linoth]

Is your feature request related to a problem? Please describe.
On 6/8, Bluesky rolled out the ability for users to attach up to 10 images to a single post. Because any number of images greater than 4 uses this new carousel format, rss-bridge does not seem to recognize or attach these to feed entries, or show any indication that images are present on the original site.

Describe the solution you'd like
Attaching the images would be ideal, but even some sort of indicator that images are present on the post but not displayed would help.

thank you for reporting this. I did add this in my fork but forgot to push it to here.
its noted that it theoretically supports up to a hard limit of 20 images and that video embeds in a carousel is TBD.

I'll keep an eye out for any developments on the api implementation of the video embeds, but for now it should be fine regardless of the number of images.

Hello, the current version of BlueskyBridge from c4d220f breaks previously existing bluesky RSS feeds by replacing URL parameter data_source by context.

edit:
As I'm running RSS-Bridge on my own server, I've added a rewrite rule in my root .htaccess to permanently redirect to the new correct parameter. (Not sure yet if it works perfectly. My RSS reader should automatically update existing feeds.)

#SECTION BEGIN redirect BlueskyBridge URLs to new parameters
RewriteEngine On

# Case 1: params before AND after data_source=getAuthorFeed
RewriteCond %{QUERY_STRING} bridge=BlueskyBridge
RewriteCond %{QUERY_STRING} ^(.+)&data_source=getAuthorFeed&(.+)$
RewriteRule ^(.*)$ /?context=Posts+from+a+user&%1&%2 [R=301,L,QSD,NE]

# Case 2: params only after data_source=getAuthorFeed
RewriteCond %{QUERY_STRING} bridge=BlueskyBridge
RewriteCond %{QUERY_STRING} ^data_source=getAuthorFeed&(.+)$
RewriteRule ^(.*)$ /?context=Posts+from+a+user&%1 [R=301,L,QSD,NE]

# Case 3: params only before data_source=getAuthorFeed
RewriteCond %{QUERY_STRING} bridge=BlueskyBridge
RewriteCond %{QUERY_STRING} ^(.+)&data_source=getAuthorFeed$
RewriteRule ^(.*)$ /?context=Posts+from+a+user&%1 [R=301,L,QSD,NE]

# Case 4: no other params
RewriteCond %{QUERY_STRING} bridge=BlueskyBridge
RewriteCond %{QUERY_STRING} ^data_source=getAuthorFeed$
RewriteRule ^(.*)$ /?context=Posts+from+a+user [R=301,L,QSD,NE]

#SECTION END redirect BlueskyBridge URLs to new parameters

you are right, please update your RSS feeds or use your redirect solution as a workaround.
The idea for this is to remove and minimise the parameters used and use contexts for different types of bluesky feeds. At the moment there is only one ("Posts from a user") but I am considering adding a "Posts from User List, Starter Pack or Feed Generator" context in the future.

@mruac I've just got my first bsky post with more than 4 images attached since using your feature. It's working great, thanks.

The rewrite is working as expected and should make my feed reader update the 100+ bsky feed I'm subscribed to. (My feed reader offers no possibility to update a feed URL, but it should do it automatically from a permanent redirect after a 72 hours delay.)

Maybe the rewrite rules will be useful for others than can use it?

[mruac]

That could be an option for the core RSS-Bridge libraries, to handle cases when a bridge removes or updates a parameter. Not for me though.
