Clojurians Log v2

@timok the clojure CLI now added support for codeberg domains, so you can publish it as org.codeberg.timokramer/charm.clj

I wonder if I should add jline to bb so people can make TUIs with it (and potentially run libs like this)

you can already do TUI stuff but mostly via shelling out to gum (or via bblgum lib) or a pod

the main thing withholding me from adding jline is that they are now at version 3.. how fast do these versions come out and how much churn will this add to bb

yeah, I thought about this as well since jline seems the only needed dep to make a tui on jvm. there is already a jline4 alpha release. would be cool of course to have it in babashka.

wait, one example of a pure bb TUI is this one: https://github.com/yannvanhalewyn/prstack/ for inspiration

oh wait, it also seems to be using gum now :)

let me try to make a PoC for bb with jline3 where you can run this lib... but hearing about jline4 already makes me worried

can't find any traces of jline4 though

https://github.com/jline/jline3/releases/tag/4.0.0-SNAPSHOT

but it's under the jline3 repo

yeah, it makes no sense that they always switch to a different repo, don't know why is that

any more info on this?

nah, i don't think it will happen soon

can you explain why you are using this version?

org.jline/jline-terminal-jni {:mvn/version "3.26.1"}

here is a good explanation to this: https://github.com/jline/jline3/pull/1374

jni is the prefered terminal interface

ok... and you tested it with graalvm native-image right?

any additional config needed?

yeah, in examples you can find the setup i used for it

This is awesome! I have always been upset with the state of TUI in clojure. I have so many use-cases for this. Really nice work

In a private converdation, @timok and I figured out how to make jline work with bb :)

borkdude man ... you are a scholar and a gentle-mensch 🖖 😄

I was searching for something like that for some time! Looking forward to use in https://eca.dev/ in the future, would be nice to add some screenshots of what's possible

noted

Any screenshots of functionality that you've implemented?

FYI io.github.yourname/charm.clj

yeah, not published yet...but it won't be io.github i guess

Hey @timok this is exactly what I and @adityaathalye were looking for the past week. Keep me in loop for any help needed for testing and ui.

or packaging

yeah, will be investigating some testing with probably charmbracelet/vhs @hmisraji07 very happy for collaboration.

sure @timok.

Let's connect this weekend

Continued: • Fix https://github.com/squint-cljs/squint/issues/792: prn js/undefined as nil • Fix https://github.com/squint-cljs/squint/issues/793: fix yield* IIFE (needs wrapping in parens) • https://github.com/squint-cljs/squint/pull/779: Added compare-and-swap!, swap-vals! and reset-vals! (https://github.com/tonsky) • https://github.com/squint-cljs/squint/pull/788: Fixed compilation of dotimes with _ binding (https://github.com/tonsky) • https://github.com/squint-cljs/squint/pull/790: Fixed shuffle not working on lazy sequences (https://github.com/tonsky) • Multiple :require-macros with :refer now accumulate instead of overwriting (https://github.com/willcohen) • Allow macro namespaces to load "node:fs", etc. to read config files for conditional compilation • Don't emit IIFE for top-level let so you can write let over defn to capture values. • Fix js-yield and js-yield* in expression position • Implement some? as macro • Fix https://github.com/squint-cljs/squint/issues/758: volatile!, vswap!, vreset! • pr-str, prn etc now print EDN (with the idea that you can paste it back into your program) • new #js/Map reader that reads a JavaScript Map from a Clojure map (maps are printed like this with pr-str too) • Support passing keyword to mapv • https://github.com/squint-cljs/squint/issues/759: doseq can't be used in expression context • Fix https://github.com/squint-cljs/squint/issues/753: optimize output of dotimes • alength as macro • Inline identical? calls • Clean up emissiong of paren wrapping • Add nat-int?, neg-int?, pos-int? (https://github.com/eNotchy) • Add rand • Fix rendering of null and undefined in #html • https://github.com/squint-cljs/squint/issues/747: #html escape fix • Optimize nested assoc calls, e.g. produced with -> • Avoid object spread when object isn't shared (`auto-transient`) • Optimize str even more • Remove debug output from compilation • Optimize =, and, and not= even more • not= on undefined and false should return true • Optimize code produced for assoc, assoc! and get when object argument can be inferred or is type hinted with ^object • Optimize str using macro that compiles into template strings + ?? '' for null/undefined • Fix https://github.com/squint-cljs/squint/issues/732: take-last should return nil or empty seq for negative numbers • https://github.com/squint-cljs/squint/issues/725: keys and vals should work on js/Map • Make map-indexed and keep-indexed lazy

goddamn that's a lot of fixes

Nice work!
