在go / golang中代表换行符的最便携/跨平台的方式是什么？ [英] What is the most portable/cross-platform way to represent a newline in go/golang?

问题描述

目前，为了表示go程序中的新行，我使用 \\\
。例如：

 包主
 
导入fmt
 
 
 func main（）{
 fmt.Printf（％d是％s \\\
，'U'，string（85））
} 
  

...将产生 85是U ，然后是换行符。

然而，这似乎并不是跨平台的。查看其他语言，PHP用全局常量（ PHP_EOL ）表示它。

>解决方案

我对此感到好奇，所以决定看看 fmt.Println 完成了什么工作。 http://golang.org/src/pkg/fmt/print.go

如果您滚动至底部，您将看到 if addnewline 其中 \\\
总是被使用。我几乎不会说这是否是最跨平台的方式，而go最初是与linux绑定的，但这就是std lib的原因。

我原本打算建议使用 fmt.Fprintln ，这可能仍然有效，就好像当前的功能不合适，错误可能会被提交，然后代码只需要用最新的Go工具链进行编译。

Currently, to represent a newline in go programs, I use \n. For example:

package main

import "fmt"


func main() {
    fmt.Printf("%d is %s \n", 'U', string(85))
}

... will yield 85 is U followed by a newline.

However, this doesn't seem all that cross-platform. Looking at other languages, PHP represents this with a global constant ( PHP_EOL ). Is \n the right way to represent newlines in a cross-platform specific manner in go / golang?

解决方案

I got curious about this so decided to see what exactly is done by fmt.Println. http://golang.org/src/pkg/fmt/print.go

If you scroll to the very bottom, you'll see an if addnewline where \n is always used. I can't hardly speak for if this is the most "cross-platform" way of doing it, and go was originally tied to linux in the early days, but that's where it is for the std lib.

I was originally going to suggest just using fmt.Fprintln and this might still be valid as if the current functionality isn't appropriate, a bug could be filed and then the code would simply need to be compiled with the latest Go toolchain.
