How can one search and replace 2 lines (together) via eclipse?

 

I would like to search multiple files via eclipse for the following 2 lines: 

@Length(max = L_255)
private String description;

and replace them with these two: 

@Length(max = L_255, message="{validator.description.len}")
private String description;

Search are multi-line by default in Eclipse when you are using regex: 

(@Length(max = L_255))([rns]+private)

I would like to add "private String description;" 

(@Length(max = L_255))([rns]+privates+?Strings+descriptions*?;)

replaced by: 

1, message="{validator.description.len}")2

It works perfectly in a File Search triggered by a CTRL-H.

Eclipse多行搜索

As mentioned in Tika's answer, you can directly copy the two lines selected in the "Containing Text" field : those lines will be converted as a regexp for you by Eclipse.

Another tip on how to get the regex for a selected block. Open one of the files that contains the multiple lines (multiline) to search or replace. Click Ctrl+F and select "Regular expression". Close the Find/Replace window. Select the block you need and click again Ctrl+F to open the Find/Replace window. Now in the Find text box you have the regular expression that exactly matches your selection block.

(I discovered this, only after creating manually a regexp for very long block :)

CTRL+H does take two lines if you use regexp (and you don't have to write the regexp by yourself, eclipse does that for you).

  • Select your lines.
  • Click CTRL+H. The search dialog opens up. If "Regular expression" is already checked, eclipse will have converted the two lines you search for into regexp for you, click Search. If "Regular expression" if not already checked", check it and click Cancel (eclipse remembers your choise).
  • Select your lines again.
  • Click CTRL+H. The search dialog opens up. This time "Regular expression" is already selected. eclipse will have converted the two lines you search for into regexp for you, click Search.
