[Boost-users] Reusing expressions::stream

11 Aug 2015

      Hello,

with boost log I have:

using namespace boost::log;

add_file_log
(
  "sample.log",
  keywords::format =
  (
    expressions::stream
    << expressions::format_date_timeboost::posix_time::ptime("TimeStamp", 
"%H:%M:%S")
    << " [Rank: "<< expressions::attr<int>("Rank") << "]"
    << ": " << expressions::message
  )
);

which works fine.

Now that may be a maximum stupid questions. But when I want to reuse the 
format expressions for other uses, e.g. another sink, how can I do that?

i.e. how to declare and use a variable that holds that expressions?

:-/

Thanks,
Florian
