I was just thinking about this idea the other day, I’ll have to give it a shot soon!

[cedric]

Feedback welcome!

So cache, essentially is kotlin repl + a number of built-in functions/properties that mimic coreutils and bash?

[cedric]

@Ibragimov Yes, that’s the idea, although technically, it’s not a REPL that understands bash commands, it’s a core that reads lines and interprets them either as commands or Kotlin

[cedric]

After having tried so many ways on bash and zsh to implement a smart prompt which all failed in bizarre ways, it was a relief to implement my prompt in Kotlin. And that one works all the time 🙂

Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

You forgot to checkin the gradle jar file.

[cedric]

oops

[cedric]

Let me fix that

[cedric]

It was .gitignored, duh. Pull again, @suresh

[suresh]

👍

generating a native-image (graalvm) would nice

[cedric]

Good idea, I haven't quite thought about the packaging.

[cedric]

all classes need to be known at native image generation time so that the static analysis can process them.

This might be an issue if I want users of Kash to be able to add their own classpath before the shell launches

[cedric]

I was leaning toward a wrapper approach for now, like Kobalt/Gradle.

[suresh]

yeah that’s the limitation for AOT compilation.

jdk11 still has this warning message

[cedric]

I'm running jdk-11.0.3 and not seeing that message

[cedric]

How do you make it happen?

[suresh]

oops sorry jdk12

openjdk version "12" 2019-03-19

[cedric]

Bleeding edge uh

[cedric]

Is it working otherwise?

[suresh]

yes 👍

[ribesg]

Wow

[Joram Visser]

Is there a reason you named the fat jar kosh-fat (instead of for example kash-fat)? Or just a consistent typo (in build.gradle.kts, kash, kash-debug and run)?

[cedric]

I initially called the project kosh until I realized that kash would be a much better name, with the dollar sign and all. I forgot to rename in a few places...

[Joram Visser]

👍

[bdawg.io]

Is there shell compatibility for redirecting stderr? In bash you could do 2> /dev/null to suppress errors

[cedric]

Not yet, it's on the TODO list: https://github.com/cbeust/kash/blob/master/TODO.md

[cedric]

It's trivial to add

[cedric]

@bdawg.io I just added support for 2>, let me know how it works for you
