[Boost-users] [xpressive] literals in regex without escaping...

Hello *,

I need to parse some logger lines using boost xpressive. The line looks
like:

fname:line_no   [severity]  logging message

When building the xpressive regex if I need to match the severity (e.g.
[INFO]) I need to escape the square brackets... Is there some xpressive
construct (like as_xpr) which makes from all characters literals. So that I
can write smth like:

sregex re = *_ >> literals("[INFO]") >> *_

Many thanks,
Ovanes
