* Filters, Formatters and attributes: An attribute is a different think than a filter. Filters contains attributes as part of its expressions.
attr< logging::severity_level>("Severity") should return the attribute value when called.
The following expression
attr< logging::severity_level>("Severity")>= logging::info
should return a filter. Can this make be possible and unanbigous?
See our conversation with Steven on this topic. In short, it needs researching on my side. On the spot I can see the problem with attr returning the attribute value upon being called, if more than one type is specified.
Does this mean that you will take care of the separation between attributes/filters and formatters?
This means, I will try to, but I can't promise that I'll succeed.
How many rotation files are maintained?
You can specify maximum total size of the files or minimum free space on the drive.
Can this number be configured?
See here:

I dont see how to configure the number of rotation files? Could you show me how?
As I said, you can't give the actual number of files, but you can limit their size. If you construct the backend like this: boost::shared_ptr< sinks::text_file_backend > backend( new sinks::text_file_backend( keywords::file_name = "file_%5N.log", keywords::rotation_size = 5 * 1024 * 1024 )); backend->set_file_collector( sinks::file::make_collector( keywords::target = "./logs", keywords::max_size = 100 * 1024 * 1024, )); You won't have more than 20 files in the ./logs directory.
