Notepad++ 正则表达式反向引用似乎不起作用 [英] Notepad++ regex backreference doesn't seem to work

问题描述

我需要在不以结尾的每一行末尾添加;:, {, } 或 ).

I need to add ; at the end of every line that does not end with :, {, } or ).

我在 Notepad++ 中使用这个:

I'm using this in Notepad++:

• 搜索:[^:\{\}\)]$
• 替换为:\1;

它找到的字符串没问题，但它用 ; 替换了在行尾找到的最后一个字符，而不是将其添加到其中.我尝试了 $1 而不是 \1 但它没有改变任何东西 - 找到的文本仍然被删除.

It finds the strings all right but it replaces the last character found before the end of line with ; instead of adding it to it. I tried $1 instead of \1 but it didn't change anything — the found text still gets deleted.

推荐答案

你的模式没有捕获组，因此 \1 是一个空字符串.改用 $0 来引用整个匹配项:

Your pattern has no capturing group, hence \1 is an empty string. Use $0 instead to refer to the whole match:

查找内容:[^:{})]$
替换为:$0;

然而，在某些边缘情况下它可能会失败([^:{})]$ 模式匹配除 :、{ 之外的任何字符code>、} 和 )，因此在行结束前至少需要 1 个字符)，也许，您最好在此处使用负向后视:

However, it might fail in some edge cases (the [^:{})]$ pattern matches any char other than :, {, } and ), so requires at least 1 char before a line end), perhaps, you should better use a negative lookbehind here:

查找内容:$(?<![:{})])
替换为:;

$(?<![:{})]) 模式匹配行尾(使用 $)，然后是 (?<![:{})]) 负向后视确保没有 :、{、} 或 >) 紧接在当前位置的左侧.

The $(?<![:{})]) pattern matches the end of line (with $) and then the (?<![:{})]) negative lookbehind makes sure that there is no :, {, } or ) immediately to the left of the current location.
