Updates

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

• babashka: native, fast starting Clojure interpreter for scripting.
  • Support self-contained binaries as uberjars!
  • Add java.security.KeyFactory, java.security.spec.PKCS8EncodedKeySpec, java.net.URISyntaxException
  • Fix babashka.process/exec wrt babashka.process/*defaults*
  • #1632: Partial fix for (.readPassword (System/console))

  • nREPL: implement ns-list op
  • SCI: optimize swap!, deref and reset! for normal atoms (rather than user-created IAtoms)
• sci.configs: A collection of ready to be used SCI configs.
  • A configuration for hoplon and javelin was added. You can play around with hoplon in a SCI-enabled environment here
• clj-kondo: static analyzer and linter for Clojure code that sparks joy.
  • #2207: New :condition-always-true linter, see docs)
  • #2013: Fix NPE and similar errors when linting an import with an illegal token

  • Handle multipe source :paths in a more robust fashion
  • #344: macros can't be used via aliases
  • Add squint.edn support, see docs
  • Add watch subcommand to watch :paths from squint.edn
  • Make generated let variable names in JS more deterministic, which helps hot reloading in React
  • Added a vite + react example project.
  • Resolve symbolic namespaces (:require [foo.bar]) from :paths
  • Add bit-and and bit-or
  • Include lib/squint.core.umd.js which defines a global squint.core object (easy to use in browsers, see docs)
  • Add subs, fn?, re-seq

• neil: A CLI to add common aliases and features to deps.edn-based projects Version 0.2.62 released

• clojure-mode
  • Porting this CLJS project such that it can run with squint also. You can now use this library directly from NPM as a JS library. See this page for a demo on how to use it directly from a CDN! This work is funded by Nextjournal.
• cherry: Experimental ClojureScript to ES6 module compiler
  • Released version 0.1.9
• grasp: Grep Clojure code using clojure.spec regexes
  • Fix self-requiring namespace (which clj-kondo now also catches via optional linter!)

  • Minor fixes in glob by @eval, thanks!
• deps.clj: A faithful port of the clojure CLI bash script to Clojure
  • Get home directory via environment variable rather than system property by @DerGuteMoritz, thanks!
• babashka.nrepl: The nREPL server from babashka as a library, so it can be used from other SCI-based CLIs
  • Fix classpath op
  • Implement ns-list op

These are (some of the) other projects I'm involved with but little to no activity happened in the past month.
