no #ktistec release this week. i have been working on bookmarked posts, pinned/featured posts, as well as some minor performance improvements, but i need to spend time fixing an issue with my libxml extensions that is preventing me from moving to the latest release of #crystallang. i've been putting it off but it's gotta get done, so...

@alexanderadam works!

macro ✂️(str, n)
  {{str}}.size > {{n}} ? {{str}}[0, {{n}} - 1] + "…" : {{str}}
end
 puts ✂️ "hello, world!", 3  # => "he…"

#crystallang

TIL

The … (the Unicode ellipsis character) works as both a Crystal Language macro and method name, as in:

macro …(str, n)
  Ktistec::Util.render_as_text_and_truncate({{str}}, {{n}})
end

Which can be used in a view template as:

= … preview, 120

I'm not saying you should. I'm saying you can.

There are two big features in release v3.1.3 of Ktistec: auto-approve followers and a new image viewer.

Auto-approve followers is conceptually simple ("the server automatically sends an Accept activity when it receives a Follow activity") but it required extensive changes to some of the oldest code in the codebase: the inboxes and outboxes controllers. I refactored inbox and outbox side-effect processing into independent services, which made it possible to support side-effects like auto-approve follow (and also auto-follow back), without having to go through the controllers.

A more significant change for me personally was replacing the lightGallery image gallery (an external dependency) with my own implementation. It's not as slick, and not as full of features—I wrote it in two days—but it is fully free software, and that's important to me.

Added

• Add admin page for managing OAuth access tokens.
• Add support for auto-approve followers. (fixes #26)
• Add support for auto-follow back.

Fixed

• Prevent triggering actor refresh when user is anonymous.

Changed

• Replace "lightgallery" dependency with custom image viewer.
• Set OAuth access token expiry to 30 days (previously expired after 24 hours).
• Refactor inbox and outbox processing into dedicated processor services.

The OAuth changes set the groundwork for better support of the Mastodon API and the Fediverse clients that depend on it. Stay tuned!

I'm working on federation issues.

👻 Release v3.1.2 of Ktistec improves support for Lemmy and community servers like it that distribute content by wrapping it in Announce activities (FEP-1b12: Group federation support). Ktistec also supports the audience property, although support for that was removed from Lemmy earlier this year.

🎃 This release also adds support for delivering to shared inboxes, which are widely supported by other ActivityPub servers. Despite being federated, the Fediverse is not highly distributed, and this optimization can reduce outbound delivery traffic by 10-20x.

Added

• Support for the Dislike activity.
• Support for the audience property on activities and objects.
• Support for delivery to shared inboxes.
• Support for full-width hash signs in hashtags (e.g. ＃日本語) commonly used in Japanese and other Asian languages.

Fixed

• Strip HTML from object summaries rather than escaping it.
• Properly unwrap Lemmy-style Announce activities.

Changed

• Destroy discarded drafts instead of deleting them.

Enjoy!

Vacations are wonderful. It is a privilege to be able to travel without worry. It's also wonderful to be home, and to have the time to work on projects I care about. With those thoughts in mind, I present release v3.1.1 of Ktistec, an ActivityPub server written in the Crystal programming language!

This release is a mixed bag of small features and improvements:

Added

• Auto-link URLs in posts. (fixes #24)
• Support searching by actor username. (fixes #102)
• Support hourly granularity in metrics charts.

Fixed

• Mark actor as down if refresh fails.
• Remove draft posts from the everything collection.
• Ignore charts with no points in the date range.
• Ensure HTTP::Client instances are closed.

I added support for multiple users at the beginning of the month. I'm very interested in feedback on how that's working out for anyone using it.

This release of Ktistec merges the main_3.x branch into the main branch.

Managing two branches, and two releases, was a lot of work. And sometimes changes were lost in the shuffle, like:

Added

• Add a small banner to highlight "offline" status.
• Support YAML MCP prompts and hot-reloading.

I have about a dozen more features and fixes that are ready for the next release, but to keep things simple, I'm doing the merge first, in its own commit.

Release v2.4.16 of Ktistec... because I forgot to include some critical code in v2.4.15... namely, the menu.

Changed

• Reorganize the admin menu.

If you're not planning on adding additional users, you don't need to update!
