Question

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?

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.
