In Eclipse 3.3.2, I would like to replace a character (say ',') by a new line in a file. What should I write in the "Replace with" box in order to do so ?
EDIT : Many answers seems to be for Eclipse 3.4. Is there a solution for Eclipse 3.3.X ?
Check box 'Regular Expressions' and use '\R' in the 'Replace with' box
It's a new feature introduced with Eclipse 3.4, See What's New in 3.4
Check box 'Regular Expressions' and use '\n' in the 'Replace with' box
Like the others said, just use regular expression, but instead of just \r, put \r\n
I'm using Helios and it works, however I had some issues with replacement... I wanted to place a line break between any of these brackets "><" (to make each new XML tag go to a new line)... first I had to place a chacter between the 2 brackets, for instance /r, after this i checked the "regular expressions" box and replaced the /r with \R, which resulted in the correct linebreak. otherwise, the replace seemed to be greyed out.
I've just found an article about that problem. It seems to be a bug.
There's a workaround which is to copy a new line in clipboard and then paste it inside the "replace" box.
if the file search is performed with Regular Expressions checkbox checked, then replace all / replace selected will also allow regular expression and will transform \n to a newline in the file(s)
