[英]Delete all lines (not) matching a regex using Notepad++
How to delete all lines matching or not matching a regex in Notepad++? 如何在Notepad ++中删除所有匹配或不匹配正则表达式的行?
In Vim, I'd do the following to delete all matching lines: 在Vim中,我会执行以下操作来删除所有匹配的行:
:g/regex/d
And to delete all non matching lines: 并删除所有不匹配的行:
:!g/regex/d
I'm looking for these commands' equivalent in Notepad++. 我在Notepad ++中寻找这些命令。
As also explained in " Notepad++ - delete all lines with certain text ", I usually go for the approach of blanking the matching lines and deleting the blank lines afterwards. 正如在“ Notepad ++ - 删除具有特定文本的所有行 ”中所解释的那样,我通常会采用消隐匹配行并删除空行的方法。 Is there a simpler way? 有更简单的方法吗?
As per this answer , versions of Notepad++ >= 6.0 support matching line breaks in regex, thus allowing to delete whole lines directly without creating blank lines first. 根据这个答案 ,Notepad ++> = 6.0的版本支持正则表达式中的匹配换行符,因此允许直接删除整行而不首先创建空行。 The following pattern should remove all lines containing "foobar" when replaced with an empty string: 当替换为空字符串时,以下模式应删除包含“foobar”的所有行:
^.*foobar.*\r\n
Now, as discussed in " Regular expression to match a line that doesn't contain a word? ", negating regular expressions isn't exactly straightforward. 现在,正如“ 正则表达式匹配不包含单词的行? ”中所讨论的那样,否定正则表达式并不是很简单。 Deleting lines in Notepad++ which do not contain "foobar" would require the following pattern: 删除Notepad ++中不包含“foobar”的行将需要以下模式:
^((?!foobar).)*\r\n
Because that's a quite complicated command to type just for removing lines which don't contain a word (or possibly more complex expression), I wonder if there is an easier solution. 因为这是一个非常复杂的命令,只是为了删除不包含单词的行(或者可能是更复杂的表达式),我想知道是否有更简单的解决方案。
在“ Find
对话框的“ Mark
选项卡上,您可以为与之匹配的行添加书签...然后在菜单上Search > Bookmark > Remove Unmarked Lines
或Remove Bookmarked lines
