can you tell more? there is a clojure library: https://github.com/edma2/clojure-msgpack but I'm not sure how well it works and it won't be that fast when converting loads of data

It seems it requires java.io.DataInput which isn't in bb, but I could add that

depending on your use case, you could also use nbb + a node lib for this

but if you're interesting in having clojure-msgpack work in bb, let me know

the potential use case is to provide data for a csharp program that uses msgpack. Now I'm thinking json will do. It it some non critical code path

for fun, I will add the necessary classes for https://github.com/edma2/clojure-msgpack, to see if it works for you, if it doesn't you can fall back to JSON anyway

what OS are you using bb on?

lul nice. Linux but this script would be for windows

Could you test with this linux one? https://25888-201467090-gh.circle-artifacts.com/0/release/babashka-0.7.5-SNAPSHOT-linux-amd64-static.tar.gz And the https://github.com/edma2/clojure-msgpack library. Windows binary still building in CI.

(require '[msgpack.core :as msg])
(require 'msgpack.clojure-extensions)

(assert (msg/pack {:compact true :schema 0}))
; => #<byte[] [[email protected]>

(assert (:compact (msg/unpack (msg/pack {:compact true :schema 0}))))
; => {:schema 0, :compact true}

@U02CV2P4J6S Windows binary: https://ci.appveyor.com/api/buildjobs/j6gd482myt9b662r/artifacts/babashka-0.7.5-SNAPSHOT-windows-amd64.zip

sick

Let me know if this adds any value, I haven't merged this to master yet

I can say I use it for my thingy now. Beyond that I don't know what the tradeoffs are

no real disadvantages, just wondering if the messagepack lib is working correctly

at first glance it does. I guess I can try with testcheck or something. Isn't there something that makes arbitrary objects?

Just a smoke test on your project will do.

I'll merge

😄

you can always get the latest master build from https://github.com/babashka/babashka-dev-builds

ah that is sweet

jo borkdude now I'm trying on windows ends up java.io.DataInput is missing there still. Version 0.7.5. Sorry for the late followup. wait maybe I'm lying ok yea I can confirm 0.7.5 works

so it works - problem solved?

yes

I was just doing something with the wrong version 🙈

no problem :)

@U01LR7M2B7A has done some cool stuff with org-babel and babashka.

libpython-clj doesn't work with babashka.

you might have more luck with #nbb - there you can use any Node.js library which may have some good plotting libraries

or just shell out to Python

or build a Python pod around plotting. https://github.com/babashka/pods/blob/master/examples/pod-lispyclouds-sqlite/pod-lispyclouds-sqlite.py

Whenever I need to do this I shell out to a system utility, like pbcopy on osx for example.

You could shell out to a python script with pyperclip to get cross-OS clipboard compatability.

https://pypi.org/project/pyperclip/

I lazy load dependencies like this:

(defn can-do? [program] (= 0 (:exit (sh "command" "-v" program))))

(defn install-or-noop [program install-fn]
  (when-not (can-do? program)
    (println (<< "You don't have {{program}} installed. Installing now..."))
    (install-fn)
    (println (<< "{{program}} should be installed now. Thanks!"))))

@U11BV7MTK I could see if that java.awt clipboard thing works with bb, without adding too much binary size... What was the invocation again?

what do you mean?

i am asking because i might do some scripting in the future. No need quite yet. And no idea how many others would find it useful

Something like this, but those awt classes aren't in bb yet: https://gist.github.com/exupero/1462ec16d8874dee9ee710257eaf3d3c I think with bb you could just shell out to pbcopy on mac, e.g.

@(babashka.process/process ["pbcopy"] {:in "dude"})

and then dude is in your clipboard

yeah that would work on osx right now. I was wondering if there was a portable way

i can make my own local scripts, but if anyone on windows wanted to share they are out of luck conceptually

yeah, that's where the .awt thing comes in, or you could dispatch on OS name to do the most likely thing

not sure if Windows has something like pbcopy

Ah, there is: https://superuser.com/a/472601

There is a predicate in babashka.core named windows? which only returns true on Windows

(for now that's the only function there)

some linuxes also have xclip so to be fully portable you could check with fs/which which one is available on which OS

We could paste that portable function on the babashka wiki

and in wayland linux it would be wl-copy

btw, I tried getting awt clipboard stuff into bb but it's not playing so well with graalvm (and adds binary size), so I think dispatching on os + finding the appropriate binary would still be best

That's so nice that you checked. Thanks @U04V15CAJ

if you use osc52 enabled terminal like xterm, windows terminal, mintty, etc. you can use https://chromium.googlesource.com/apps/libapps/+/HEAD/hterm/etc/osc52.sh, should be straight forward to port it to pure bb.
