Clojurists Together Project Update, 01-02/2024, Tommi Reiman

Clojurists Together Project Update, 03-04/2024, Tommi Reiman

Finally! Reitit 0.7.0 is out. It has been over a year in the making, spanning multiple libraries: reitit, malli, schema-tools, [spec-tools](https://github.com/metosin/spec-tools and ring-swagger-ui. Big thanks to everyone involved. There is a lot of draft work that has been queued and can now be worked on. New releases should come more frequently in the future.

Reitit 0.7.0 (all 8 alphas flattened)

0.7.0 (2024-04-30)

The OpenAPI3 release, Year in the making - the changes span over multiple repositories!

Clojurists Together Project Update, 05-06/2024, Tommi Reiman

Started my 3 month sabbatical in June with a road-trip with the kids, a welcome reset! Now back to home, learning and doing. Refreshed my knowledge of latest TypeScript, Zod and XState with an goal to pull some of the good things to Clojure (into Malli + a fully Xstate-compatible FSM-library). Also working on a template-project with monorepo + malli + reitit, using Java21 and Virtual Threads.

My planned Open Source Time got postponed due to small family crisis, so no big releases.

Had some time to help people, do PR reviews and small updates to viesti, to be released later this year or early next.

Reserved OS time for December, to (╯°□°)╯︵ LIBS out!

Reflected on my year of working with Open Source. Having authored tens of Clojure Open Source Libraries makes you look things from another angle. Instead of just adding more (fun) features, I dedicated time to go through all old issues and open PRs from 2024 for the active and stable libraries where there is no clear lead developer or it's me.

Closed a lot of support tickets, answered questions and reviewed and merged PRs. Thanks to all contributors and sorry to not doing this earlier!

Some releases:

Malli 0.17.0

  • Don't output :definitions nil in swagger. #1134
  • BREAKING: :gen/fmap property requires its schema to create a generator.
    • previous behavior defaulted to a nil-returning generator, even if the schema doesn't accept nil
    • use :gen/return nil property to restore this behavior
  • Support decoding map keys into keywords for [:map schemas in json-transformer #1135
  • :not humanizer #1138
  • FIX: :seqable generates nil when :min is greater than 0 #1121
  • FIX: malli.registry/{mode,type} not respected in Babashka #1124
  • FIX: :float accepts doubles but never generates them #1132
  • FIX: :float missing humanizer #1122
  • Updated dependencies:
fipp/fipp '0.6.26' to '0.6.27'

Ring-http-response 0.9.5

  • Fix pre-expr syntax #34
  • updated dependencies:
[ring/ring-core "1.13.0"] is available but we use "1.12.2"

Going Forward to 2025

Yes, it's already 1.1! I did not apply for Clojurists Together funding as I didn't have the time I wished for to work on Open Source. Not going anywhere, but need to figure out a way to continue the work in a sustaineable way. Cheers.
