<<boost::log::expressions::format_named_scope(_scope, 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!

Hi,
Being new to Boost.Log (and Boost in
general) I have spent the last few days trying to implement Boost.Log -
which
Is working fairly well by now.
However - I encountered one problem
that I've not been able to solve by now, although it seems to me quite
trivial:
I have successfully registered the "named_scope"
attribute and I am populating its value by a call to BOOST_LOG_FUNCTION.
This works well and I can see the function-name
in my log-output.
However - I also want the line-number
and the file-name, and discovered that there's a possibility to set the
output-format of the
"named_scope" attribute (which
already incorporates file-name and line-number info) like so:
#include <boost/log/expressions/formatters/named_scope.hpp>
sink->set_formatter(expr::stream
<< expr::format_named_scope("Scopes", "%n"));
As documented here:
http://www.boost.org/doc/libs/1_54_0/libs/log/doc/html/log/detailed/expressions.html#log.detailed.expressions.formatters.named_scope
I just don't seem to find any way to
get to my sink - which is configured in a settings-file and evaluated by
a call to the init_from_stream()
function.
Is there any way to query for all the
sinks - or get a sink by name? How is one supposed to set a sink formatter
for a sink which was generated by the library
and not the user?
Or is there a way to specify the output-format
for named attributes via a settings-file as well? As far as I can see it's
only possible to format the output of a log record as a
whole - but not single attributes.
Also: Is it correct, that the above
function will only set the format for the "Scopes" attribute
- which means I could call this function repeatedly for lets say the "TimeStamp"
attribute
as well?
Best regards,
David
