在Groovy中使用反斜杠 [英] Using backslashes in Groovy

问题描述

我正在使用groovy编写一个脚本，该脚本替换UNC服务器名称和部分目录结构.我有以下内容:

I'm using groovy to write a script that replaces UNC server names and a part of the directory structure. I have the following:

def patternToFind = /\\\\([a-zA-Z0-9-]+)\\share\\([a-zA-Z]+)/
def patternToReplace = '\\\\\\\\SHARESERVER\\\\share\\\\OPS'

这行得通，但是所有这些都很难看.我在正则表达式中理解为什么使用 \\\\ 查找 \\ ，但是令我困惑的是为什么在替换中我必须使用四个 \ 等于一个 \ .

This works, but all those \'s are pretty ugly. I understand in the regex why \\\\ is used to find \\, but what is confusing me is why in the replacement I'm doing I have to use four \'s to equal one \.

如果有人有更好的方法可以做到这一点，我将不胜感激.目标是替换

If anyone has a nicer way to do this I would greatly appreciate it. The goal is to replace

\\<服务器> \ share \< env>

具有< server> 和< env>

谢谢！

我想我应该澄清一下.SHARESERVER和OPS实际上是变量.因此，真正的最终结果将是:

I guess I should clarify. SHARESERVER and OPS are actually variables. So truly the end result would be something like:

def serverName = //some passed in server
def env = //some passed in env

def patternToFind = /\\\\([a-zA-Z0-9-]+)\\NAS\\([a-zA-Z]+)/
def patternToReplace = '\\\\\\\\' + serverName + '\\\\share\\\\' + env

因此，我想到的唯一方法是构建一个字符串文字来替换我要查找的部分.

So the only way I think of doing it is building a string literal to replace the section I'm looking for with.

我将是第一个承认我对reg ex很烂的人，因此，如果您可以使用它们来捕获字符串中的值并将该值替换为另一个值，那么我将不知所措.

And I'll be the first to admit that I suck at reg ex, so if you can use them to capture a value in a string and replace just that value with another, I'm all ears.

推荐答案

不兼容

def patternToReplace = $/\\SHARESERVER\share\OPS/$
