Hello! @ilya.chernikov I was wondering if there is a way to have the autocomplete working in a kotlin script with dependencies in IntelliJ/AndroidStudio
eg:

@file:Repository("<https://repo.maven.apache.org>")
@file:DependsOn("org.apache.commons:commons-text:1.6")

[ilya.chernikov]

Hi! It’s a bit complicated question. What in particular you want to autocomplete and in which scenario? E.g. are your scripts a part of a project sources?

[gianluz]

hmmm no the script is an easy script that need to be run standalone.. using kotlin-main-kts.jar and with some dependencies eg what i described in the message..
i can see that in IntelliJ there is a section in Preferences -> Languages & Frameworks -> Kotlin -> Kotlin Scripting
where i can find some default stuff like KotlinBuildScript or KotlinInitScript or plain Kotlin Script. and i cannot find a way to add kotlin-main-kts and see the script with autocompletion in the IDE..

[gianluz]

will be nice if from intelliJ i'm able to use the autocomplete for a script.main.kts with the relatives deps.. that's all 😄

[ilya.chernikov]

Ok, if it is a standalone file, then you need to configure main.kts scripts: open Intellij settings -> Build, Execution, Deployment -> Compiler -> Kotlin compiler. There are two scripting-related fields at the bottom of the setting page. Place the path to kotlin-main-kts.jar to the “Script templates classpath” field and org.jetbrains.kotlin.mainKts.MainKtsScript to the “Script template classes” field.
Then it should work.

[ilya.chernikov]

You should be able to see main-kts script enabled in the settings -> Languages and Frameworks -> Kotlin -> Kotlin scripting.

[gianluz]

ok let me try to play with this! i will let you know if it works! 🙂 thank you very much!! i really appreciate

[gianluz]

i've setup in
Script template classes: /full/path/to/kotlin-main-kts.jar
Script templates classpath org.jetbrains.kotlin.mainKts.MainKtsScript
but in Languages and Framework i still cannot see the main.kts script.. i've tried also to restart/invalidate cache.. same 😕 maybe i'm wrong

[ilya.chernikov]

Let me check it myself now…

[gianluz]

btw i'm using the last intelliJ if relevant 😄

[ilya.chernikov]

It works for me:

[gianluz]

yay! i was right as well! was just stuck somehow my intelliJ

[gianluz]

is working! this is amazing!!

[gianluz]

😄 thank you so much!!

[gianluz]

one more question.. and what if i want to add another jar to the script classpath? can i do something like:
/path/to/kotlin-main-kts.jar:/path/to/another.jar ?

[gianluz]

asking because from command line you can do -cp /path/to/kotlin-main-kts.jar:/path/to/another.jar

[ilya.chernikov]

Yes, you can do it. Path as in the regular classpath, and class names separated by comma

[gianluz]

Hello! is me again! @ilya.chernikov 😄 sorry to bother you!! i would like to know if there is a way to make a intellij plugin that adds automatically your custom Script Definitions.. i've extended MainKts and added some more stuff, but i would like to find an easy way (maybe by installing a plugin) to recognize the custom script

[ilya.chernikov]

Hi!
Yes, installing a plugin is a preferable method, the one I shown you is created more as a workaround. But we do not have any plugin for the main-kts, at least not yet.
If you’re willing to make one yourself, you need to implement the extension point kotlin.script.experimental.intellij.ScriptDefinitionsProvider, which should be obviously similar to the fields in the settings.

[gianluz]

I Need to investigate little bit more also because I never made a plugin, but with this infos I have a great start point! Thank you very much @ilya.chernikov very kind of you! Appreciate your help!

[gianluz]

i've implemented my plugin with this specs:
in plugin.xml

<extensions defaultExtensionNs="org.jetbrains.kotlin">
        <scriptDefinitionsProvider
            id="DangerFileScriptDefinitionProvider"
            implementation="com.gianluz.dangerkotlin.intellij.DangerFileScriptDefinitionProvider"/>
        <!-- Add your extensions here -->
    </extensions>

then my implementation here:

class DangerFileScriptDefinitionProvider : ScriptDefinitionsProvider {
    private companion object {
        private const val ID = "DangerFileScriptDefinition"
        private const val DANGERFILE_SCRIPT_DEFINITION = "com.danger.kotlin.kts.DangerFileScript"
    }

    override val id: String
        get() = ID

    override fun getDefinitionClasses(): Iterable<String> = listOf(
        DANGERFILE_SCRIPT_DEFINITION
    )

    override fun getDefinitionsClassPath(): Iterable<File> {
        return listOf(
            File("/usr/local/lib/danger/danger-kotlin.jar"),
            File("/usr/local/lib/danger/kotlin-main-kts.jar"),
            File("/usr/local/lib/danger/danger-kotlin-kts.jar")
        )
    }

    override fun useDiscovery() = true
}

but i get an error

Caused by: java.lang.NoClassDefFoundError: kotlin/script/experimental/intellij/ScriptDefinitionsProvider
...

am i missing something?? 🤔

[ilya.chernikov]

There is a missing dependency. Could you try to get the full stacktrace or root cause exception?

[gianluz]

Stacktrace

Stacktrace

[ilya.chernikov]

This is still incomplete, the reason for PluginException os trimmed. Maybe you can find the full one in the log.
I do not know much about this part. Maybe it is better to debug or to ask IntelliJ guys, how to diagnose it.

[ilya.chernikov]

BTW, live plugin has an implementation of this extension point https://github.com/dkandalov/live-plugin/blob/master/src/main/liveplugin/pluginrunner/kotlin/LivePluginKotlinScriptProvider.kt
Maybe you can use it as an example
