I'd like to know if the following is possible using Eclipse.
This is for use in a code generator.
Imagine I have a piece of Java code that stretches over many lines and
builds a String like this:
String mystr = "the " +
"cow " +
"said " +
"moo " +
"moo " +
"moo " +
"! ";
I want to write a refactoring routine where the user hilights a line that
will have a condition added. For example, I could highlight the last
"moo" and the refactoring routine would add an IF so that the code changes
to this:
String mystr = "the " +
"cow " +
"said " +
"moo " +
"moo ";
if ( someFlag == true )
{
mystr += "moo ";
}
mystr += "!";
Is there a way to programmatically parse through the String declaration,
see the last "moo", end the statement before it, surround the last "moo"
with a condition and append the trailing "!" as in the code above?

If the code
String mystr = "the " +
"cow " +
"said " +
"moo " +
"moo " +
(someFlag ? "moo " : "") +
"!";
would be ok, too (it should be equivalent), this could be easily done using
code templates:
(${condition} ? ${word_selection} : "")
Take care, Ilja
