Updates

Last week I delivered my babashka talk at Strange loop talk and much of my attention went to the preparation of that (slides here). Hopefully the talk will be online soon. Keep an eye on the Strange Loop Youtube channel.

EDIT: the talk is now available here.

I did manage to get some coding done as well, despite testing positive for COVID when I arrived back home...

Here are updates about the projects/libraries I've worked on last month.

• clj-kondo: static analyzer and linter for Clojure code that sparks joy. Published a new version (2023.09.07) with these changes:

  • #1624: Use Oracle GraalVM 21 (@lispyclouds)
  • Use PGO to speed up loops (now 2-3x faster for (time (loop [val 0 cnt 10000000] (if (pos? cnt) (recur (inc val) (dec cnt)) val)))!)

  • Bun compatibility
  • Lots of bug fixes
  • REPL improvements
  • Adopt CLJS truth semantics: 0 and "" are no longer considered falsey

  • Small release with the option to add your own header on top of format-opts, thanks to @Sohalt
• http-client: babashka's http-client
  • A number of small bugfixes and additions
• A number of experiments around squint:
  • bun-squint-loader: a demo of how to implement a loader for bun which lets you directly load .cljs files which are then compiled using
  • squint cloudflare worker
• rewrite-edn: Utility lib on top of rewrite-clj with common operations to update EDN while preserving whitespace and comments
  • Fixed a round-tripping issue by bumping rewrite-clj

  • Add experimental :static-methods override to control how a static method is invoked. This allowed a fix in babashka for Thread/sleep on non-longs and for Class/forName which works arond a bug in Oracle GraalVM 21.
• sci.configs: A collection of ready to be used SCI configs.
  • @holyjak made a configuration for Fulcro which can be seen live in action here
