Test Case 1:
1. paste
----------%<----------
	int foo() {
		return "".length();
	}
----------%<----------
2. place caret after '(' on the return line
3. press 'Enter'
4. Ctrl+I
==> indent gets destroyed


Test Case 2:
1. paste
----------%<----------
public class Test {
	private void helper2(boolean[] booleans) {
		if (booleans[0]) {

		}
	}
}
----------%<----------
2. place caret before ')' on the if line
3. press 'Enter'
4. Ctrl+I
==> indent gets destroyed

Besides adding a new test, I have modified 'testAnonymousIndentation2' in JavaHeuristicScannerTest.java.

Deepak, please make the first review.

Comment 4 Deepak Azad 2011-02-07 07:44:09 EST

Rajesh, is there a reason for this check "if ((line != -1) && (line != fLine))" ? 

The tests pass with the following code, and I cannot think of a case where this would fail.
-----------------------------------------------------------------------
if (matchParen) {
	if (skipScope(Symbols.TokenLPAREN, Symbols.TokenRPAREN)) {
		fIndent= fPrefs.prefContinuationIndent;
		return fPosition;
	} else {
-----------------------------------------------------------------------

Being over cautious and trying to be sure that it is a continuation scenario. But the following 2 lines (785/786) in the execution path already ensure this which is why none of the potential failure cases never occur - 

"if (isFirstTokenOnLine)
		matchParen= true;"

Thx. New patch removes the check.
