hi, quick question: I do have compiled a kotlin project to a jar file. now I want to pass parameters, I do so java -jar bg.jar --angle 2. However java -jar bg.jar --angle '-2' does not work.

[stephanmg]

Exception in thread "main" java.lang.IllegalStateException: Missing value for CLI argument --angle

[stephanmg]

probably not related to Kotlin, I apologize, but maybe somebody can hint how to do this? I seem right now I can't wrap my head around this triviality.

[stephanmg]

thanks!

[Cicero]

sorry for the quick gun jump here but it seems the parameter is not being recognized, maybe it’s not a string value?

[stephanmg]

yeah you are right, it's not a string value. so I need negative numbers, should I make this angle parameter a string param? then parse teh double

[stephanmg]

@Cicero oh well that's my own code, never mind. lol. 🙂 found the problem

[stephanmg]

for some reason I had weird custom command line argument parsing in my code

[stephanmg]

there are option parsers for kotlin, right? so I don't have to do this.

[stephanmg]

guess that was pretty old code

[stephanmg]

well i mean in the standard library

[Cicero]

😅 I’m happy to help?

[stephanmg]

What I meant was: Is there a standard way to handle commadn line arguments in Kotlin.

[stephanmg]

like a standard argument parsing library

[Cicero]

Do I understand it’s something “like this”: Reading a name from the command line | Try Kotlin (kotlinlang.org)

[Cicero]

Or this one Kotlin command-line compiler—Kotlin (kotlinlang.org)

[stephanmg]

yeah i thought about using https://github.com/Kotlin/kotlinx-cli

[stephanmg]

but I didn't want to include any non-standard dependencies into the project actually

[stephanmg]

standard librry dependencies

[Cicero]

I know what you mean but this library tells me something like you would need to use it

[Cicero]

When you find this kind of thing inside of the Kotlin repo, then it’s kind of unavoidable

[stephanmg]

then there is https://www.kotlinresources.com/library/kotlin-argparser/

[stephanmg]

I'm just baffeld what to use.

[stephanmg]

for now I'm using a little code to manage CLI arguments myself

[stephanmg]

so no additional library needed

[Cicero]

Cool, but I would go with Kotlin repo solution always, even then argparser looks fancier.

[stephanmg]

What is Kotlin repo solution?

[Cicero]

https://github.com/Kotlin/kotlinx-cli -> Kotlin source
https://www.kotlinresources.com/library/kotlin-argparser/ -> xenomachina

[stephanmg]

thanks

i see
