Clojurians Log v2

How do you read from environment vars in babashka? Looked at https://book.babashka.org/ but didn’t find any examples.

Nevermind! It’s (System/getenv "HOME")

Noob question: Does bb graalvm compiled work for Windows?

I realized the CI build only has linux, linux-static and macos

And I remeber your talk on Clojure Berlin talking about running bb on windows 😛

Yes

See appveyor.yaml

thanks

I use appveyor for all Windows stuff

@borkdude any reason to use appveyor instead of windows Github Action image?

I don't know if there is anything missing from the GH image, just wondering if the same work could be done there

Found this: https://gist.github.com/sogaiu/e079cd770051685c46ab24b6658effcf

Appveyor is just a lot easier, I find

And I have already figured that out, GH probably works, but I'm not interested in GH actions per se

Thanks, I'll give a try on GH to follow the repo standard, I'll let you know if it works

@ericdallo, all rewrite-clj v1 scripts are written in babashka and run on linux, macOS and Windows via GitHub Actions. https://github.com/clj-commons/rewrite-clj/blob/f640a38d9267adb0a6a7e06453a13402aa61c9b1/.github/workflows/unit-test.yml#L64.

Cool, thanks @lee

@lee this is not about installing bb, it's about compiling a graalvm project on Windows, but thanks :)

yeah, but thanks anyway, it's good to know that 🙂

I am not objecting against people installing bb everywhere

Ah! Okey dokey! :simple_smile:

But now that you are here. Maybe this is already documented at clj-graal-docs? :)

Unless I am still misunderstanding (which is entirely possible), maybe this will help? I do graalvm native-image on GitHub Actions on macOS, linux and Windows for rewrite-clj. https://github.com/clj-commons/rewrite-clj/blob/18d772889dfbd7680fa255ec3eca916912d733cb/.github/workflows/native-image-test.yml

Yes, that is very helpful. This is indeed the gnarly bit I do on appveyor as well: https://github.com/clj-commons/rewrite-clj/blob/18d772889dfbd7680fa255ec3eca916912d733cb/.github/workflows/native-image-test.yml#L112-L116

Oh right that was a bit nasty to figure out.

Also I never did figure out what was needed to setup for GraalVM native-image JDK8 for GitHub Actions on Windows so I only do JDK11.

https://github.com/babashka/babashka/blob/23e12a11ee5c42b3c0ab3ffb39777409c9451dbe/appveyor.yml#L45

What would be the difficulty with jdk8 then?

oh, it's very helpful indeed

It has some https://www.graalvm.org/docs/getting-started/windows/ that I did not work to figure out how to setup on GitHub Actions: > For GraalVM based on JDK 8, you will need MSVC 2010 SP1 version. The recommended installation method is using Microsoft Windows SDK 7.1: > > 1. Download the SDK file GRMSDKX_EN_DVD.iso for from https://www.microsoft.com/en-gb/download. > 2. Mount the image by opening F:\Setup\SDKSetup.exe directly.

Oh crap yeah, that stuff. Let's just ignore it ;)

Exactly the conclusion I came to!

Going forward I only use 11 unless there's some weird bug which requires my to use 8

Yeah, I could probably drop GraalVM JDK8 testing entirely now for rewrite-clj v1. Even more attractive how that reflection fixups aren’t needed anymore for JDK11.

for graalvm yes, but not for normal JDK I'd say, since people may still use 8

Agreed for sure.

yeah, except that reflection config which now took its place

here a tweak there a tweak everywhere a tweak tweak

It's a more lovely tweak than the other one

yes, the tweaks are getting less tweakier

Oh that action for setupping graalvm is useful too, since it checks automatically the os running

https://github.com/DeLaGuardo/setup-graalvm? Yes, very handy!

@jayzawrotny found out that this CSS-producing lib works with babashka: https://github.com/cdaddr/gaka

It’s pretty amazing that it’s over 10 years old but still works.
