使用Scala IDE在Scala中使用线包装长久的函数定义 [英] Line wrapping long curried function definitions in Scala with Scala IDE

问题描述

这是一个简单的问题，但是我很好奇在Scala中绕线的函数的正确方式。例如，假设我有一个较长的行（如果不够长，你可以假装有更多的参数）：

This is a simple question, but I'm curious about the "right" way to line-wrap curried functions in Scala. For example, suppose I have the moderately long line (if it's not long enough, you can pretend there are more parameters):

  def executeFooBarCommand(ce: CommandExecutor)(implicit ec: ExecutionContext): Future[FooBar] = {
    //...
  }

我有两个关于包装长定义的问题：

I have two problems regarding wrapping the long definition:

首先，我不知道接受的最佳做法（或更长的）。

First, I'm not sure what the accepted best practice is for wrapping such lines (or even longer ones.

第二，最合理的包装线的方法似乎是在包装线的自动重新加入我在eclipse中格式化，我设置eclipse不会在java中加入包装线，并且在scala IDE格式化部分似乎没有相关设置，我可以找到，所以我不知道如何防止格式命令

Second, most reasonable ways of wrapping the line seem to result and in "auto-rejoin" of the wrapped lines when I format in eclipse. I set eclipse never to join wrapped lines in java, and there doesn't seem to be a relevant setting in the scala IDE formatting section that I can find, so I'm not sure how to prevent the format command from joining these wrapped lines.

推荐答案

Eclipse基于 scalariform ，到目前为止它没有这个选项。但是，它可以在相同的参数列表中分割参数，因此您可以尝试将其格式化为：

Eclipse is based on scalariform, and so far it doesn't have this option. However, it can split parameters in the same parameter list, so you could try formatting it as:


def executeFooBarCommand（
ce：CommandExecutor）（implicit ec：ExecutionContext）：Future [FooBar] = {
// ...
}
