kotlinlang #scripting

I can't find information on this, I found different things on different places: Is there an official way to define Maven dependencies and to cashe compilation or is ktscript still the preferred way for running scripts? I found it super convenient to just append --idea and have an idea instance set up.

I want to use kotlin scripting as my devops related script and run it on Docker Container. Can we download the deps first so when executing

kts

it will not fetch jar file from maven repo?

@holgerbrandl I noticed that kscript only works if you put everything in DependsOn on a single line. Is that expected?

What do you mean exactly? I have this file at the root of an Android Studio project (which uses Kotlin and

.gradle.kts

), but the syntax highlighting is not there apart from keywords and strings as I said.

How would I create a simple kotlin script and edit it using IntelliJ? Do I really need to create a project?

Hello, World! I was looking at kts for the first time. It’s not clear whether it’s possible to write scripts that depend on some maven lib. I’ve seen the

@file:dependsOn

annotation in the KEEP, but is it implemented?

well limited sounds better than not possible at all @ilya.chernikov is there a issue for that i can track ?

Are options 1 and 2 completely off-base?

I'm trying to convert my JSR-223 usages into the new experimental scripting API, but every script I attempt to compile gives me two errors: - One instance of

No class roots are found in the JDK path: /usr/lib64/openjdk-8/jre

- Several instances of

Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option

How can I address these?

compilerOptions.append("-jvm-target", "1.8")

HA! After couple of hours of digging through kotlin code I've found the problem, will try to contribute fix next week 🙂

How can I turn on the syntax highlighting for top level kts scripts on Intellij? tried adding the stdlib to the module but didn't work

Nikky

apparently a kotlin script cannot implement abstract function the script definition.. or at least ide things its a conflicting overload

Nikky

01/21/2019, 10:33 AM

but despite the loads of complaints/wishes for improvement i have for scripting it is still better than any alternative, good job JB

one thing that came to mind earlier.. is it possible to cache the script compilation results ?

Hi guys, i'm trying to make my script be recognized by the intellij, I create the file on templates but still not working, someone can help me ?

Hi @ilya.chernikov, how I can tell the JvmScriptCompier the ClassLoader to load the script? all JvmGetScriptingClass properties is private

SrSouza

01/24/2019, 5:19 PM

@ilya.chernikov Hi, when a should use

ScriptEvaluationConfigurationKeys.constructorArgs

? My code loads the script and return to me a KClass, no a new object from the compiled script

val evalConfig = ScriptEvaluationConfiguration {
        constructorArgs(plugin)
        set(JvmScriptEvaluationConfiguration.actualClassLoader, bukkriptClassLoader)
    }

    val clazz = bukkriptCompiledScript.compiledScript.getClass(evalConfig).resultOrSeveral(plugin)

In this case a should not use

constructorArgs()

SrSouza

@ilya.chernikov you have plan to in the feature create a Parse object that you use on the compilation. In my project a need to parse two times, the first ALWAYS will Fail because he is used for get something from a annotation and put on a list to sort the scripts for compile correctly. You can see here: https://github.com/DevSrSouza/Bukkript/blob/recode/host/src/main/kotlin/br/com/devsrsouza/bukkript/host/Host.kt#L26 If the script API has a parse object or something, this could be faster

The files have highlighting and completion, but the default imports aren't being recognized by IntelliJ and are marked as red.

Nikky

01/27/2019, 7:16 PM

does anyone know of a way to make gradle spit out the location of the jdk that is being used ? that would be very helpful for passing it as system property to the scripting stuff

SrSouza

Hi @ilya.chernikov, I'am with a problem in refine annotations. My script have a annotation that all the parameters have default values, and in the script I put one parameter and get this exception. I guess that the parse not work with annotations with default parameters. My annotation class:

@Target(AnnotationTarget.FILE)
@Retention(AnnotationRetention.SOURCE)
@Repeatable
annotation class Script(
    val name: String = "",
    val version: String = "",
    val author: String = "",
    val authors: Array<String> = emptyArray(),
    val website: String = "",
    val depend: Array<String> = emptyArray(),
    val pluginDepend: Array<String> = emptyArray()
)

Hi all, I encounter some issues when I’m trying to integrate kotlin-scripting (v1.3.11) into my Apache Flink (v1.7.1) application. One of the runtime dependencies of kotlin-scripting is kotlin-compiler-1.3.11.jar, which conflicts with Flink due to log4j.

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.log4j.Level.toLevel(Ljava/lang/String;Lorg/apache/log4j/Level;)Lorg/apache/log4j/Level;
	at org.apache.log4j.helpers.OptionConverter.toLevel(OptionConverter.java:198)
	at org.apache.log4j.PropertyConfigurator.parseCategory(PropertyConfigurator.java:753)
	at org.apache.log4j.PropertyConfigurator.configureRootCategory(PropertyConfigurator.java:648)
	at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:514)
	at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:580)
	at org.apache.log4j.helpers.OptionConverter.selectAndConfigure(OptionConverter.java:526)
	at org.apache.log4j.LogManager.<clinit>(LogManager.java:127)
	at org.slf4j.impl.Log4jLoggerFactory.getLogger(Log4jLoggerFactory.java:81)
	at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:329)
	at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:349)
	at org.apache.flink.client.cli.CliFrontend.<clinit>(CliFrontend.java:99)

So I use kotlin-compiler-embeddable-1.3.11.jar as the runtime dependency instead. The exception above is gone, but the following error occurs when evaluating kotlin script:

Failure(reports=[ScriptDiagnostic(message=com/intellij/openapi/util/Disposer, severity=ERROR, location=null, exception=java.lang.NoClassDefFoundError: com/intellij/openapi/util/Disposer)])

Does anyone have idea how to solve this issue? Is it possible to make kotlin-compiler-embeddable-1.3.11.jar as the default runtime dependency of kotlin-scripting? Thanks!

i did the same.. replcing it with -embedable.. saves me a gradn total of 2 MB on the jar it seems

I figured out that I need to add

implicitReceivers

both in compilation configuration and evaluation configuration, but now I have

java.lang.IllegalArgumentException: Unknown key Key(baseClass)

i am guessing that custom annotations giving access to new symbols will also probably not be supported by IDEA ?

Personally, I was trying to generate kts files in that step (with kotlinpoet) and add them as

importScripts

. Doesnt seem to run my code tho 😞

that actually works.. it tested it.. just not the IDE integration part

i solved it by added all files into sourceroots via gradle

downside is that all things get compiled multiple times now.. once by gradle and once by kotlin scripting

efemoney

02/04/2019, 10:42 AM

Yep. IDE integration also works too if they are in source root.

Nikky

02/04/2019, 11:19 AM

the problem with that is that runnig a gradle task like a JavaExec will waste effort and might not accurately reflect which symbols are actually available when you just run the jar
