All the pan/zoom libraries I tried suuuuuuucked, so I ended up rolling my own from scratch. The pinch zoom isn't quite where I want it, but it's a start. If anyone wants to contribute some code for improving that, please let me know.

• Support zoom, pan, and rotate
  • Mouse scroll to zoom
  • Click/grab to pan
  • Rotate via on-screen buttons
  • Double-click to quick zoom in/out by 2x
• Gesture support
  • Pinch zoom in/out
  • Swipe up to zoom in
  • Swipe down to zoom out
  • Swipe left or right to close the zoom modal
  • Other gestures may be added once I figure out a clean way to differentiate them from conflicting mouse events

That said, I do like waving things (and people) away.

To that end, I've added some gesture recognition in a few places, mostly modals. Any modal can now be dismissed with a left or right swipe in an area not bound by other event handlers.

• e.g. You can't swipe in the text field to dismiss an edit/report/ban/remove modal; you have to swipe outside of that.
• Left/right swipe was chosen as to not interfere with scrolling so it could be used consistently across all modal types.

The only other place, currently, with gesture support is the image zoom modal (described above).

I may add some additional swipe actions where it's intuitive to do so. For now, I'm content with modals being easier to dismiss on mobile without having to reach up to the close button in the top corner.

Actions include:

• Go to profile
• Message in Lemmy / Matrix
• Block User
• Search for alts / simiarly-named accounts
• Ban user from instance (admins only)
• View user on their home instance
• Copy Lemmyverse link for user

• Images can be pasted in the post's URL field as well as in the markdown editor.
• Images can optionally be pre-processed to webP along with a user-selectable quality level. Especially useful if your instance limits the size of uploads
• Can delete post images (only before you save the post; unfortunately there's no way to retrieve the delete token after that even though it is stored in the DB. Yet another API limitation :sigh:)
  • This is addressed in 0.19.4, but I don't have support for that yet.
• Images pasted/uploaded into the markdown editor are tracked in a bar along the bottom of the editor. Individual images can be deleted as needed along with the corresponding markdown code for them.

This setting behaves differently for mods and admins:

• Mods: Filter will be applied to all posts/comments except in communities of which you are a moderator.
• Admins: Filter will be applied to all posts/coments except those made to communities local to your instance or those made to remote communities of which you are a moderator.

Comments made by new users will be hidden, and that includes any replies (essentially behaves the same way as blocked users)

This information has also been added to the instance items at /instances

Please note that the "Activities behind" counter is only an estimate. The value for newest_activity_id is not provided by the API (because that would be useful, so why would the Lemmy devs include it?), so it has to be estimated. The estimation is done by looking at the last_successful_id of all the linked instances and grabbing the highest number and subtracting the last_successful_id for the selected instance. Not all of those activities would necessarily be coming to your instance (votes/posts/comments to communities yours isn't subscribed to, etc), so it is merely an estimation. Just because it shows you are behind by X number doesn't necessarily mean it's behind by that many.

When loading a video via click-to-play, I'm conditionally setting the "autoplay" flag where the embed API supports it, but it doesn't always seem to be honored. This is an attempt to not have to press "play" twice for a video. So far, the only video frontend that seems to honor it is YouTube. Invidious/Piped, so far, do not, and neither does PeerTube.

Ok, so autoplay works if muted (no idea how YouTube's player gets around this; probably some chicanery). I think that's worse because you still have to click twice on the videos, and the "unmute" button is harder to reach than "play". So I think I'm going to just settle on having to click play twice.

This seems to be be a Chrome/Chromium thing (and explains why YT gets to bypass this). In Firefox, the autoplay flag is respected without having to mute the video.

If media embeds are enabed in the feed, only YouTube frontend will show direct embeds. Piped/Invidious will always be click to play regardless of embed setting due to above mentioned rate limiting / performance.

• On posts with links, it currently has buttons to search for the article at Archive Today, Ghost Archive, and 12ft.io
• On Youtube-like posts, can select alternalte links for YouTube, Invidious, or Piped
  • Invidious/Piped will open with your preferred instance (defined in settings)
  • Useful if someone posts a video to an Invidious instance that performs poorly for you and you would prefer to view it on your preferred Invidious/Piped instance or canonically on YouTube.

• Main, Community, and User feed pages: Quick Actions has replaced all discrete menus
• Search Page, Modlog, instances page, and Community Browser: All of the filtering options are in a quick action menu

These will be combined with the built-in list and the admin-extended list and be available for use as your preferred YT frontend and for detection of Piped/Invidious links in posts.

Be aware that those custom instances will only render as embeds for you; they will be thumbnails for anyone else who hasn't added them to Tesseract. If you feel that instance should be added to Tesseract's built-in list, please submit a Github issue with the details.

Tesseract is pre-populated with the official list of public instances for each, but it can get out of date easily.

Note: As of 6/20/2024, I've noticed a lot of Invidious/Piped instances are now requiring login, and embeds through them no longer work. I believe if you have an account with one, log in, and enable 3rd party cookies for that domain, the embeds should work. I have not tried that, but it does work with Spotify. This isn't a Tesseract bug, unfortunately, or I'd fix it.

• Or, more specifically, removed 0.18.x JS client and the extensions I wrote to make that compatible with 0.19.x. Now uses the 0.19.3 JS client.
• Removed the image upload proxy which was needed in 0.18x due to CORS restrictions.

• Added safety check so that the auth token is only ever sent to the profile's associated instance and cannot accidentally send to non-home instance (e.g. when browsing communities on a remote instance).
• Fixed a few chicken/egg situations where the profile store needed to be accessed before it was initialized
• If your auth token is invalid, such as after changing your password on another device, you will get a toast message you can click to take you to the login screen.
• If a profile exists for a username/instance combo, logging in will update the auth token for that existing profile rather than creating a new one.
• User avatars are now fetched when logging in.

• Embeds now have a short timeout when leaving the viewport before they're removed from the DOM and turn back into thumbnails. Fixes annoyance when resizing the window while a video is playing and the video temporarily leaves the viewport and is destroyed. Timeout is 2 seconds and will reset/disarm if the post returns to the viewport before it expires.

• Uses new upload handler for banner/icon
• Can pre-process the banner/icon to webP before uploading
• Shows a live preview of how the community card will look

• Slightly darkened background color in light mode cards (bg-white->bg-slate-100) for better contrast. Did similarly for some button colors
• Added "OpenDyslexic" as a UI font option
• Can now close modals with Escape key, close button, or by swiping left/right
• Added button to reveal password fields
• Some modals can be closed by clicking out of them.
  • I need to disable this or make it more consistent. Some workflows utilize nested modals, so I do need to be able to keep them open when interacting with a child modal.
• Added "share" link for searches.
  • Will generate a URL with the current search params and copy to your clipboard.
