I wrote about how to write command-line tools in Kotlin Multiplatform instead of Bash
https://dev.to/jmfayard/how-to-write-a-command-line-tool-with-kotlin-multiplatform-45g2

while i’m a kotlin fan
i’m not sure i’d go this way for a cli
perhaps a native exec via graalvm if you really really want
but more probably go (🤮) or rust (❤️)

[nfrankel]

the maven daemon is a graalvmified java app

[jmfayard]

I'm not making any claims on Kotlin vs Go vs Rust.
All of them are better than Bash.
I would pick whatever is your favorite programming language, or otherwise makes sense in your context.

Now if your favorite language is Kotlin, I present how to build the CLI tool faster.

I'm not sure why you would want to use GraalVM since we have Kotlin native

[Mark Murphy]

FYI, I think there is a typo in your first code snippet. You have:

cd kolin-cli-starter

...which I suspect should be:

cd kotlin-cli-starter

(BTW, nice post!)

[jmfayard]

Thanks Mark!

I’m not sure why you would want to use GraalVM since we have Kotlin native

separation of concern and speed of development
with graalvm, i write my app first
and then i can decide it’s not performant enough and make it a native executable
i’m able to defer an important decision
with kotlin native, i’ve to think about what implementations are platform-specific
and design my code around that

[nfrankel]

btw, i agree with you about bash scripts needing to be short or maintained by somebody else 😂

[Matteo Mirk]

The need for proficiency in one’s most used and favourite language (being Kotlin here), which Jean-Michel advocates, so as to employ it for shell scripting, reminded me of this: https://www.teamten.com/lawrence/writings/java-for-everything.html

i love kotlin
and i also think that “I just choose the right language for the job” is just showing off
either you a deserve a huge pay check because you know that many programming languages so well
or you’ve got an inflated ego because you think you can learn a new one easily (TL;DR: syntax is mostly easy, the ecosystem... not so much)
what is adequate is to choose the right language among the ones you already know
that being said
yes, the author write about bad experiences of choosing to use another programming language
but you could find other bad experiences about choosing to use the same one 🙂
for static > dynamic, i 200% agree
