也许你可以使用TextFX插件

在TextFX中，点击TextFX编辑→删除空行

我在查找/替换窗口中使用\r\n个正则表达式时运气不太好。

然而，这适用于notepad++ v4.1.2:

Use the "View | Show end of line" menu to enable display of end of line characters. (Carriage return line feeds should show up as a single shaded CRLF 'character'.) Select one of the CRLF 'characters' (put the cursor just in front of one, hold down the SHIFT key, and then pressing the RIGHT CURSOR key once). Copy the CRLF character to the clipboard. Make sure that you don't have the find or find/replace dialog open. Open the find/replace dialog. The 'Find what' field shows the contents of the clipboard: in this case the CRLF character - which shows up as 2 'box characters' (presumably it's an unprintable character?) Ensure that the 'Regular expression' option is OFF.

现在您应该能够根据需要进行计数、查找或替换。

这似乎是一个常见问题，提供的解决方案是:

Simple search (Ctrl+H) without regexp You can turn on View/Show End of Line or view/Show All, and select the now visible newline characters. Then when you start the command some characters matching the newline character will be pasted into the search field. Matches will be replaced by the replace string, unlike in regex mode. Note 1: If you select them with the mouse, start just before them and drag to the start of the next line. Dragging to the end of the line won't work. Note 2: You can't copy and paste them into the field yourself. Advanced search (Ctrl+R) without regexp Ctrl+M will insert something that matches newlines. They will be replaced by the replace string.

将一个由多行组成的文档改为一行，每行组成逗号分隔的列表中的一个条目:

按Ctrl +f打开搜索/替换。 点击“替换”页签。 用“\r\n”填充“Find what”条目。 用“，”或“，”(取决于偏好)填充“Replace with”条目。 取消选中“匹配整个单词”复选框(回避逻辑的重要部分)。 检查“扩展”单选按钮。 点击“全部替换”按钮。

这些步骤转向。

foo酒吧 酒吧巴兹 巴兹foo

成:

Foo bar,bar baz,baz Foo

或者:(取决于个人喜好)

Foo bar, bar baz, baz Foo

我在notepad++中打开文件，并在几个步骤中进行替换:

将所有“\r\n”替换为“\r\n” 替换所有”;“\r\n”和“\r\n” 将所有“\r\n”替换为“”

这将把所有的断点放在它们应该在的位置，并删除那些破坏文件的断点。

这对我很管用。

假设它有一个“正则表达式”搜索，寻找\r\n。我更喜欢\r?\n，因为一些文件不使用回车。

编辑:感谢你的反馈，无论谁投了反对票。我了解到……没有，因为你没有提供任何反馈。为什么这是错误的?
