OSS updates November 2023

In this post I'll give updates about open source I worked on during November 2023.

To see previous OSS updates, go here.

Sponsors

I'd like to thank all the sponsors and contributors that make this work possible! Without you, the below projects would not be as mature or wouldn't exist or be maintained at all.

Open the details section for more info.

Advent of Code

It is Advent of Code time of year again. You can solve puzzles in an online squint or cherry playground here.

Change the /squint/ part of the url to /cherry/ to switch ClojureScript dialect versions.

You can read more about the playground here.

Updates

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

• blog I've written two blog posts this month:
  • Writing a Cloudflare worker with squint and bun
  • Playing Advent of Code with Squint.
• squint: CLJS syntax to JS compiler
  Lots of stuff happened in November with squint! You could say that I've grown a little addicted to improving this project currently, driven by how users use it and also while developing the playground, a lot of potential improvements emerged..
  • Restore backward compatibility with code that is compiled with older versions of squint
  • Optimize various outputs for smaller size
  • Add js-in
  • Support into + xform
  • Support sort on strings
  • #386: allow expression in value position in map literal
  • Improvements with respect to laziness in mapcat and concat
  • Do not array mutate argument in reverse
  • Escape JSX attribute vector value (and more)
  • map + transduce support
  • Fix for in REPL mode
    • Throw when object is not iterable in for
  • Make next lazy when input is lazy
  • Fix playground shim (fixes issue in older versions of Safari)
  • Add js-mod and quot
  • #380: Don't emit space in between #jsx tags
  • Add re-find
  • Add condp macro
  • Use compare as default compare function in sort (which fixes numerical sorting)
  • Allow assoc! to be called on arbitrary classes (regression)
  • Improve get to call get method when present.
  • Allow keywords and collections to be used as functions in HOFs

  • nREPL server: print values through cljs.pprint (@PEZ)
  • Initial (incomplete!) nREPL server on Node.js: npx squint nrepl-server :port 1888
  • Update/refactor threejs example
  • #360: assoc-in! should not mutate objects in the middle if they already exist
  • Evaluate lazy-seq body just once
  • Avoid stackoverflow with min and max
  • #360: fix assoc-in! with immutable objects in the middle
  • Add mod, object?
  • Optimize get
  • Add threejs example

  • Fix munging of reserved symbols in function arguments
• scittle-hoplon: a custom scittle distribution with Hoplon. I helped developing the SCI configuration for Hoplon.
• gespensterfelder: a demo that Jack Rusher wrote using Three.js ported to squint.
• neil: A CLI to add common aliases and features to deps.edn-based projects Version 0.2.63 released which adds mvn search and some bugfixes
• CLI: Turn Clojure functions into CLIs!
  • Small bugfix around priority of :exec-args and default
• aoc-proxy: a Cloudflare worker that can be used to fetch Advent of Code puzzle input from the browser (see Advent of Code playground)

• clojure-mode: Clojure/Script mode for CodeMirror 6.
  • Ported the eval-region extension to squint so you can use it straight from JS. This is used in the squint playground when you press Cmd-Enter after an expression.
