stdin does not allow further switches

[ilanpillemer]

./mme -extract -model=DEVAL_12 > temp2.kts; ./mm temp2.kts -graph works ./mme -extract -model=DEVAL_12 | ./mm - -graph does not work.

where mm is the DSL.

note running ./mme -extract -model=DEVAL_12 | ./mm - does half work, but not very useful as I need the switch.

I've tested test_script.kts - -graph with

#!/usr/bin/env kscript

println("arugment test")

for (arg in args) {
    println("arg: $arg")
}

to make sure that arguments are correctly forward to the script, which seems the case. So if stream processing fails if the option is provided, I'd suspect rather some issue with your script logic.

Could you simplify/share temp2.kts to help me reproducing the problem?

The issue is happening somehow in the preamble bash file. The kts file is piped into a preamble bash file.

It looks like kscript treats "-" as one of kscript options, not as the script. Below code in Kscript.kt seems to be the culprit.

val userArgs = args.dropWhile { it.startsWith("-") }.drop(1)

Changing it to something like below would fix the issue.

val userArgs = args.dropWhile { it.startsWith("-") && it != "-" }.drop(1)

I will give that a try this week and see if it works. And if it does put together a pull request
