Subject: Re: [Boost-users] Boost.Log: Set formatter for named_scope attr.

I have some doubts about your question: are you using the named_acope
attribute yet? If that is the case, just needs to include some other tags
like the next example

> boost::log::keywords::format = "%n (%f : %l)")

This line would print something like: "void main() (main.cpp : 25)"

If that is not the case, please, could you be more specific about how did
you set your logger? I have been struggling the past weeks with that and I
may help you. Best regards!
