在kotlin REPL中粘贴模式/多行代码段？

给定函数的骨架：

fun reformat(
    str: String,
    normalizeCase: Boolean = true,
    upperCaseFirstLetter: Boolean = true,
    divideByCamelHumps: Boolean = false,
    wordSeparator: Char = ' ',
) {
  println("In reformat")
}

我将其粘贴到kotlin REPL中，它抱怨道——显然是因为没有意识到它被发送了一个多行代码片段：

>>> fun reformat(
error: parameter name expected
fun reformat(
             ^
error: expecting comma or ')'
fun reformat(
             ^
error: expecting ')'
fun reformat(
             ^

>>>     str: String,
error: expecting an element
    str: String,
       ^
error: expecting an element
    str: String,
               ^

etc ..

什么是scala REPL中的

：粘贴
？
看起来Kotlin REPL是从IDE使用的。如果您从Intellij IDEA中打开它，它就像一个符咒，允许您进行多行输入。我没有看到任何选项允许您在常规shell中执行相同的操作。因此，在您的情况下，您可以在一行中声明函数，也可以从文件中加载脚本。
我发现一个项目-显然由JetBrains kotlin开发人员自己积极改进，解决了这个问题和其他问题：。这是他们的帮助

[0] :h
:quit or q                           quit the shell
:load or l <path>                    load file and evaluate
:type or t <expr>                    display the type of an expression without evaluating it
:list or ls                          list defined symbols
:help or h [command]                 print this summary or command-specific help
:paste or p                          enter paste mode
:syntax {on | off}                   syntax highlighting
:prompt [pattern]                    customize prompt
:set                                 set configuration parameter
:conf                                list configuration parameters
:dependsOn <artifact coordinates>    Load dependency from the current set of repositories
:repository <repository coordinates> Add repository for the artifacts lookup
:classpath or cp                     Show current script compilation classpath


这正是我想要的。它确实可以工作（尽管有丑陋的JDK9警告）：

哇，那真是个糟糕的家伙。我是JetBrains的狂热爱好者（从2008年开始），但有时我只是不想为python（vs Pycharm）或scala（vs IJ）打开IDE的开销
