Regular expressions in Eclipse: some working examples

I found very useful the Regular Expressions support in the "Find and Replace" window of the Eclipse IDE.

Here some expressions I used. Mainly a reminder for me, of course; but I think they can be useful for others as well, as working examples.

Note that you can refer to groups within the regular expression in the "Search" field, with the symbol $ followed by an increasing number: $1 for the first group defined in the regular expression, $2 for the second and so on...

From: qDebug() << "Hello" << world.name() << "t_int32" << "!";
To: ERS_DEBUG(2, "Hello" << world.name() << "t_int32" << "!");

Search: (qDebug[(][)])(\s*[<]+\s*)(.*)([;])
Replace: ERS_DEBUG(2, $3);
