is that not a typo there at your REPL prompt cljc.java-time as opposed to cljs.java-time?

one sec, I’m going to put my head through the wall if that’s the case . Standby

:man-facepalming:

Ok - there is both a cljs.java-time lib and a cljc.java-time lib. I was reading docs for one and using the other.

Thanks sir!

This is in the category of "useless advice" but having experienced much in the way of painful datetime libraries, I have come to really enjoy tick, it works the way I would expect it to with very minimal issues

and I think it is both CLJ and CLJS compatible

Well - that’s good advice actually. As I’m new to clojure, I have no preference and was just looking for a way to deal with iso8601 dates that works in babashka. So Thanks, I’ll check that out!

@U03QBKTVA0N Are you using tick in babashka by chance?

Regrettably not, and I am uncertain of its functionality therein

I am sure that when the BB wizards come back online they will have good answers for you--better than mine certainly

Ok no problem, thanks (I think it may be incompatible). However, I also use straight clojure - so this was a good tip anyhow. Thanks again 🙂

just to add some color vis-a-vis some prior investigation into tick compatibility with bb: <https://github.com/babashka/babashka/issues/554> - tl;dr tick has some blockers to compatibility with bb; cljc.java-time is compatible (it's actually one of the libraries that gets tested with each build)

You can also use Java interop directly. java.time is supposed to work: if something is missing, please report it

Thanks guys. After exploring many routes, I went with interop. For anyone that comes after, here’s what I did:

;; Read "zoned" ISO8601 timestamp and return a string in human readable local time
(import [java.time.format DateTimeFormatter]
        [java.time ZonedDateTime ZoneId])
(defn lt1 [ts]
  (let [format-string "eeee, MMMM d - h:mm:ss a"
        format (DateTimeFormatter/ofPattern format-string)
        ISO-8601 (DateTimeFormatter/ofPattern "yyyyMMdd'T'HHmmssXXXXX")]
  (-> (ZonedDateTime/parse ts ISO-8601) (.withZoneSameInstant (ZoneId/systemDefault)) (.format format))))

(println (lt1 "20221023T051551Z"))

I’m new to clojure and this was my first use of interop, worked very well.

@U0250GGJGAE That's a pretty good first interop!

Yes, all the time :)

I’ll post some tips and tricks when I’m back home but the book should give you all you need. The clojure function and shell function are available by default

Cool, I’m reading through it now.

I'm pretty happy about this one: https://github.com/clj-kondo/clj-kondo.lsp/blob/master/bb.edn

and this one: https://github.com/nextjournal/clerk/blob/main/bb.edn

so, for complex clojure invocations, you can just write (clojure "-T:build deploy") or whatever

Excellent, thank you for the complex examples

recently I've been putting more code in regular .clj files in a bb directory that I then hook up to tasks

because bb.edn doesn't have linting (yet) and coding in regular .clj files is more comfortable

That’s clever

and we also have bb -x now so you can pass arguments directly to a function
