I agree. This behavior is different from both Perl substitutions and the String.replaceAll function in Java 1.4. |
code: RE loRE = new RE("^"); String loResult = loRE.subst("abc", "x"); returns loResult=="xbc" //replaces first character but I would expect it should return loResult=="xabc" //inserts before first character. I agree that it is probably not defined by RE specification, but it seems to me similar to another case: RE loRE = new RE("$"); String loResult = loRE.subst("abc", "x"); which returns (as I would expect) loResult=="abcx"
