How can I run Kotlin-Script (.kts) files from within Kotlin/Java?
提问by Jire
I noticed that IntelliJ can parse .ktsfiles as Kotlin and the code editor picks them up as free-floating Kotlin files. You are also able to run the script in IntelliJ as you would a Kotlin file with a main method. The script executes from top to bottom.
我注意到 IntelliJ 可以将.kts文件解析为 Kotlin，而代码编辑器会将它们作为自由浮动的 Kotlin 文件来挑选。您还可以在 IntelliJ 中运行脚本，就像使用 main 方法运行 Kotlin 文件一样。脚本从上到下执行。
This form is PERFECT for the project I'm working on, if only I knew an easy way to use them from within Java or Kotlin.
这种形式非常适合我正在从事的项目，如果我知道一种在 Java 或 Kotlin 中使用它们的简单方法就好了。
What's the idiomatic way to "run" these scripts from Java or Kotlin?
从 Java 或 Kotlin“运行”这些脚本的惯用方法是什么？

Note that script files support in Kotlin is still pretty much experimental. This is an undocumented feature which we're still in the process of designing. What's working today may change, break or disappear tomorrow.
请注意，Kotlin 中的脚本文件支持仍处于实验阶段。这是一个未记录的功能，我们仍在设计过程中。今天起作用的东西明天可能会改变、中断或消失。
That said, currently there are two ways to invoke a script. You can use the command line compiler:
也就是说，目前有两种方法可以调用脚本。您可以使用命令行编译器：
kotlinc -script foo.kts <args>
Or you can invoke the script directly from IntelliJ IDEA, by right-clicking in the editor or in the project view on a .kts file and selecting "Run ...":
或者，您可以直接从 IntelliJ IDEA 调用脚本，方法是在编辑器或项目视图中右键单击 .kts 文件并选择“运行...”：

I've published a simple library that let's you run scripts from regular Kotlin programs.
我发布了一个简单的库，让您可以从常规 Kotlin 程序运行脚本。

Example
例子
The example class
data class ClassFromScript(val x: String)The
.ktsfileimport de.swirtz.ktsrunner.objectloader.ClassFromScript ClassFromScript("I was created in kts")The code to load the class
val scriptReader = Files.newBufferedReader(Paths.get("path/classDeclaration.kts")) val loadedObj: ClassFromScript = KtsObjectLoader().load<ClassFromScript>(scriptReader) println(loadedObj.x) // >> I was created in kts
示例类
data class ClassFromScript(val x: String)该
.kts文件import de.swirtz.ktsrunner.objectloader.ClassFromScript ClassFromScript("I was created in kts")加载类的代码
val scriptReader = Files.newBufferedReader(Paths.get("path/classDeclaration.kts")) val loadedObj: ClassFromScript = KtsObjectLoader().load<ClassFromScript>(scriptReader) println(loadedObj.x) // >> I was created in kts
As shown, the KtsObjectLoaderclass can be used for executing a .ktsscript and return its result. The example shows a script that creates an instance of the ClassFromScripttype that is loaded via KtsObjectLoaderand then processed in the regular program.
如图所示，KtsObjectLoader该类可用于执行.kts脚本并返回其结果。该示例显示了一个脚本，该脚本创建了ClassFromScript通过加载KtsObjectLoader并在常规程序中处理的类型的实例。
