The Mastodon-compatible API is at a stable stopping point, so I have removed the gating with_mastodon_api build flag and made it generally available.

I use the API daily via a couple different client apps. What works, works. There are known limitations, most of them rooted in architectural differences between Mastodon and Ktistec. For example, Mastodon and Ktistec manage media differently. In Ktistec, there is no simple way to upload and manage media apart from creating a post. That difference will take some work to bridge.

Here's the full changelog for this release:

Added

• Mastodon-compatible API endpoints:
  • /api/v1/accounts
  • /api/v1/accounts/lookup
  • /api/v1/accounts/:id
  • /api/v1/accounts/:id/statuses
  • /api/v1/accounts/:id/following
  • /api/v1/accounts/:id/followers
  • /api/v1/accounts/relationships
  • /api/v1/follow_requests
  • /api/v1/polls/:id/votes
  • /api/v1/preferences

Fixed

• Correctly resolve keyId from Signature header for inbox verification.

Changed

• Support both offset and cursor-based pagination in JSON collections.
• Switch following/followers pages to cursor-based pagination.

Credit goes to this thread for inspiring me to review my signature verification. There is now one more correct implementation. 😉

The next release will focus on cleaning up the internals. Ktistec is just under 100,000 lines of code, 307 source files, and 195 spec files (7030 tests). With one maintainer, the only way to stay sane is by ruthlessly refactoring and paying down the debt!

Time flies! It's already 5 years since the release of Crystal 1.0.
We're going to celebrate that! Meet the Core Team and community members looking back at that milestone, what happened since then, and what's coming next.

Release v3.3.4 of Ktistec is available.

This release adds Mastodon-compatible client support for publishing posts. Just like the previous release, however, all Mastodon API support is behind a build flag (-Dwith_mastodon_api). It's still experimental, so opt in only if you're happy to work with rough edges.

Beyond that, I focused on cleanup and refactoring throughout the codebase. Here's the full changelog:

Added

• Cursor-based pagination on actor timeline and everything pages.
• Mastodon-compatible API: /api/v1/statuses endpoint for status posting.
• Mastodon-compatible API: /api/v1/timelines/public endpoint.

Fixed

• Autosave focus handling. Fixes problems introduced in v3.3.3.
• Prevent blur from creating a draft post when publishing a post.

Changed

• Integrate X-Ray Mode colors into the theming system.
• Improve CI: add npm audit, test, and caching.
• Use npm ci in Dockerfile for reproducible builds.
• Remove very old compiler bug work-around.

🏋️ Mastodon API support is coming along—more in the next release!

#ktistec #crystallang #activitypub #fediverse

is it the expectation that atomic should be used for all class level variables now?

#crystallang

I have started work on a Mastodon-compatible API layer intended to support the many Mastodon front-ends available. It is incomplete and requires an explicit build flag to enable, but what's there (the main timeline) already works with the official Mastodon app, Tusky, and Phanpy.

Here's the full changelog:

Fixed

• Editor focus now stays in the editor after the first draft is saved. (fixes #139)
• Filter settings instructions. (fixes #135)

Changed

• Improved consistency of mini button colors.

As always, check out the full diff for the complete details.
