How to pass arguments to kotlin script?

Question

I have a windows batch

@echo off

setlocal
  call kotlinc-jvm -cp "%~dp0\lib\commons-cli-1.3.1.jar" -script "%~dp0\RmMvnRepo.kts" %*
endlocal

If I pass "-h" option to the batch, kotlinc-jvm own's help will display. But I want my RmMvnRepo.kts to receive the option. How to do that?

EDIT: No need to answer this question anymore. I've found a bug in kotlinc related to this.

You might post that link as an answer to your own question. That way you can accept it and this question will no longer show up as "unanswered", etc. Thanks for the link! — mfulton26

Think of your code wrapped in main function. Then you can access arguments through args array.

Call the script with arguments
kotlinc -script ...kts "option1" "option2"

Access the arguments through args variable
println(args.size) // will output 2

Update: Try quotes to pass -h parameter

kotlinc -script ...kts "%*"

There are some typos here. And the length of an array is called size.

Via discuss.kotlinlang.org/t/… and github.com/JetBrains/kotlin/blob/master/compiler/testData/… this the correct answer to the question "How to accept kotlin script arguments" )

As @mfulton suggested, this issue describes the problem, so I will close this question.

From a comment on that ticket:

This will be possible in 1.1.3 using the "--" delimiter for the compiler arguments and the rest (free arguments):

And the comment's example usage of --:

kotlinc -script foo.kts -- -arg value
