I have the following static regex:

I want the "*_" part to also match newline characters. I didn't see any flag to turn this on or off. Is this on by default?

It always matches exactly one character, including newlines. If you want to match one character that is not a newline ('\n'), use ~_n. To match any one character that is not a logical new line ('\r', '\n', "\r\n", others), use ~_ln. HTH, -- Eric Niebler BoostPro Computing http://www.boostpro.com
