Bug 27005 [typing] Smart string wrapping
Using1119, I noticed something quite annoying. Consider the following code: String s = ""; If you copy some code like: class A { // comment } And then you paste it between the double-quotes, you will end up with: String s = "public class A { // comment" + "}"; The problem is that this code is not equivalent. I should have a line break at the end of the first line. Otherwise the code contained in my string s doesn't even compile. So the feature is nice, but cannot be used till a line break is added at the end of each part of the string concatenation. So in the above example, I would expect: String s = "public class A { // comment\n" + "}"; or String s = "public class A { // comment\r\n" + "}"; or String s = "public class A { // comment\r" + "}"; The line break could be chosen according to the line breaks in the current file or the platform line delimiter.
