在eclipse的复制/粘贴中保留格式

Question

There is some generated code that builds a map. The values placed in map are multiline strings.
Example:

theMap.put("SOMEKEY", "Line 1 of string.  
               Also line 2 of string.  
               Perhaps more"); 

When I try to copy/paste the code to eclipse I get red errors due to the format of the value in the map.
I googled and found and here that there is a configuration in Eclipse to preserve the formatting in String literals but it does not seem to work in this case.
Is there any other configuration option?

Answer 1

If you only need to keep space, use the \\n character like this:

theMap.put("SOMEKEY", "Line 1 of string.\nAlso line 2 of string.\nPerhaps more"); 

Or if you want it multiline :

theMap.put("SOMEKEY", "Line 1 of string."
               +"\nAlso line 2 of string."
               +"\nPerhaps more");

If you paste only the string value into empty string ( "" ), to be able to do this you need to have the following setting enabled: window>preferences>java>editor>typing and check the last option (escape text when pasting into a string literals)

Answer 2

theMap.put("SOMEKEY", "Line 1 of string.\nAlso line 2 of string.\nPerhaps more");

To split into multiple lines:

theMap.put("SOMEKEY", "Line 1 of string.\nAlso line 2 of string.\n" +
        "Perhaps more");

If you want to read multiple lines from a file:

String s, fullString;
while ((s = bufferedReader.readLine()) != null) {
    fullString += s + "\n";
}
bufferedReader.close();
theMap.put("SOMEKEY", fullString);
