scala - Launch Scala REPL programmatically?

Question

I would like to launch a Scala Swing application from the command line, then after the application is started, drop into the Scala REPL to use as a control interface.

Ideally I would also like to pre-bind some variable names. Even better would be using a Java2D terminal emulator for the REPL, but I couldn't find anything appropriate.

Does the Scala REPL have a public API?

您可能会问同样的事情，就像这个问题一样，是吗？您还可以做其他事情。有一种方法可以只用代码调用 REPL，然后得到回复，这取决于你想要什么，这可能更合适。如果这就是你想要的，请澄清它，我会研究它。

至于Java2D终端，我认为使用Console's和就足够了setIn，但我可能弄错了。您可能想看看在环境中嵌入 REPL 的其他一些工作是如何做的。我认为至少有三个，但快速搜索只有Kojo，它是基于 Netbeans 的。setOutsetErr
