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!

@[email protected] tell me that when Fedify is validating an HTTP Signature you load the key identified by the `keyID`, get its `owner`, and then load the owner ActivityPub object. 🙏🏼

Crystal is good for humans and LLMs.

Crystal is a compiled language inspired by Ruby. I kept my eye on it for quite a while. And I made myself productive in it in one day.

The amount of code you have to review and refactor has grown by factors.
So recently I've been looking for something easy to review, idiomatic and portable.

A ~10 years ago I had some experience with Ruby. I liked the language but the market decided what we had to use, so Ruby became locked in RoR ecosytem. It got me thinking - Wouldn't it be an advantage? Being a one-framefork-language means that it is idiomatic in every way possible.

So I made an exeriment. I gave coding agent a task to rewrite one of my services in Crystal. I only provided the tests and documenation. If Ruby is so idiomatic, whouln't Crystal be the same?

It was a success. I've got 50% less code than original, the logic is easy to trace, and during session the agent made less mistakes. I took less time to review and fix. Considering that It's  new for me and the language is not so popular I think It's a huge success.

I'll see how it goes from now on.
