Groovy写入文件（换行符） [英] Groovy write to file (newline)

问题描述

我创建了一个简单的将文本写入文件的小函数，但是我遇到了一些问题，使得它将每条信息写入一个新行。有人可以解释为什么它把所有的东西放在同一条线上？

以下是我的函数：

$ public $ writeToFile（def directory def fileName，def extension，def infoList）{
File file = new File（$ directory / $ fileName $ extension）

infoList.each {
file< < （$ {it} \\\
）
}
}

我正在测试它的简单的代码是这样的：
$ b $ pre $ def $目录='C：/'
def folderName ='testFolder'
def c
$ b $ def txtFileInfo = []

String a =今天是新的一天
String b = 明天是未来
String d =昨天是过去

txtFileInfo<<
txtFileInfo<< b
txtFileInfo<< d

c = createFolder（directory，folderName）//这个简单的创建一个文件夹来删除
$ b中的txt文件writeToFile（c，garbage，.txt， txtFileInfo）

上面在该文件夹中创建了一个文本文件，文本文件的内容如下所示：

 今天是新的一天明天是未来昨天是过去的
  

正如您所看到的那样，文本全部聚拢在一起，而不是按每个文本的新行分隔。我认为这与我如何将它添加到我的列表中有关系？

解决方案

它看起来像我，重新在窗口中工作，在这种情况下，不是简单的 \\\
，而是 \r\\\


您可以通过 System.getProperty（line.separator）获取正确的换行符例如。

I created a small function that simply writes text to a file, but I am having issues making it write each piece of information to a new line. Can someone explain why it puts everything on the same line?

Here is my function:

public void writeToFile(def directory, def fileName, def extension, def infoList) {
    File file = new File("$directory/$fileName$extension")

    infoList.each {
        file << ("${it}\n")
    }
}

The simple code I'm testing it with is something like this:

def directory = 'C:/'
def folderName = 'testFolder'
def c

def txtFileInfo = []

String a = "Today is a new day"
String b = "Tomorrow is the future"
String d = "Yesterday is the past"

txtFileInfo << a
txtFileInfo << b
txtFileInfo << d

c = createFolder(directory, folderName) //this simply creates a folder to drop the txt file in

writeToFile(c, "garbage", ".txt", txtFileInfo)

The above creates a text file in that folder and the contents of the text file look like this:

Today is a new dayTomorrow is the futureYesterday is the past

As you can see, the text is all bunched together instead of separated on a new line per text. I assume it has something to do with how I am adding it into my list?

解决方案

It looks to me, like you're working in windows in which case a new line character in not simply \n but rather \r\n

You can always get the correct new line character through System.getProperty("line.separator") for example.
