Multiline search replace with regexp in Eclipse
提问by codegood
Eclipse regexp search works pretty well, so for example in search box I have this:
Eclipse regexp 搜索效果很好，例如在搜索框中我有这个：
(?s)(myMethod.*?;)\}\);
Now I want to copy multiline text in the IDE and in replace box, for example I want to paste \1PASTE_MULTILINE_TEXT_HERE. However Eclipse does not allow me to directly copy-paste multiline text without manually inserting newline characters.
现在我想在 IDE 和替换框中复制多行文本，例如我想粘贴\1PASTE_MULTILINE_TEXT_HERE. 但是 Eclipse 不允许我在不手动插入换行符的情况下直接复制粘贴多行文本。
In Vim (Gvim, Macvim) it works perfectly well, keeping all the spaces; how can I do the same thing in Eclipse?
在 Vim (Gvim, Macvim) 中它运行得很好，保留了所有的空间；我怎样才能在 Eclipse 中做同样的事情？

For searching multiple lines in Eclipse, you must use the 's' parameter in search expression:
要在 Eclipse 中搜索多行，您必须在搜索表达式中使用 's' 参数：
(?s)someExpressionToMatchInAnyLine
For replacing with multiple lines exp you must use \R i.e:
要用多行 exp 替换，您必须使用 \R 即：
line1\Rline2\Rline3
This will replace the matched exp with:
line1
line2
line3
这将替换匹配的 exp：
line1
line2
line3

Generally, the approach I've taken to doing this sort of thing is to type out what I want to use as a replacement, select that, open up the Find/Replace dialog, and copy the contents of the Find text box. I proceed from there and paste what I copied into the Replace text box. There is still a little work to be done (removing backslashes from in front of regex special characters that don't apply in the Replace box), but it gives me a hand up.
通常，我用来做这种事情的方法是输入我想用作替换的内容，选择它，打开查找/替换对话框，然后复制查找文本框的内容。我从那里开始并将复制的内容粘贴到“替换”文本框中。还有一些工作要做（从在替换框中不适用的正则表达式特殊字符前面删除反斜杠），但它给了我一个帮助。
