Expose plugin to headless mode

See com.intellij.idea.Main#isHeadless(java.lang.String[]) for a start.

Do you happen to know where i can find documentation for this? 

What exactly do you plan to build?

basically an different PSI miner than the one introduced in the linked paper (  https://arxiv.org/pdf/2103.12778.pdf ). 
I want an plugin that runs in headless mode. Then the plugin can be called via cmd from another program and be given a string to a project. 

Within the project it shall parse something for me an do something based on the parsing.  (the parsing part i already got covered what i still need is the knowledge of how i can start the IDE in headless mode from the other program and how i can reach my plugin within the ide.) 

See com.intellij.idea.Main#isHeadless(java.lang.String[]) for a start.

This is a good start but i still don't know were to use this method. How to configure the plugin so this is accepted as entry point. 

You may implement ApplicationStarter extension point to create a custom command-line application for IntelliJ-based IDE.

Thx very much. 

can this also be started in debug version?

Nikolay Chashnikov I'm also using the appStarter extension point. How can I start IntelliJ using this while developing the plugin?

@... see https://github.com/JetBrains/gradle-intellij-plugin/#running-dsl, you can pass args via Gradle script

same is done by builtin Gradle task building Searchable Options, https://github.com/JetBrains/gradle-intellij-plugin/blob/cae39d2c24a384fe9615148ca7b8c767be98da9c/src/main/kotlin/org/jetbrains/intellij/tasks/BuildSearchableOptionsTask.kt#L9

Thanks for the pointer. For future reference:

open class RunIdeCli: RunIdeBase(false) {

    private val traverseUIArgs = listOf("apisearch")

    init {
        args = traverseUIArgs
    }

    override fun exec() {
        super.exec()
    }

    override fun setArgs(applicationArgs: List<String>?): JavaExec =
        super.setArgs(traverseUIArgs.union(applicationArgs?.toList() ?: emptyList()))

    override fun setArgs(applicationArgs: MutableIterable<*>?): JavaExec =
        super.setArgs(traverseUIArgs.union(applicationArgs?.toList() ?: emptyList()))
}
