__FILE__ / __FUNCTION__ / __LINE__ support in metadata

[ghost]

Hey there and thanks for this library, agreed that boost::log is pretty heavy and I'm also looking for a lighter alternative.

I was wondering if you had any plans to support the standard defined preprocessor macros in the mlog::log_metadata struct, such as __FILE__, __FUNCTION__, __LINE__, etc. I find it much easier to look up in the source code where a problem is with these prepended to my log string, but they need to be captured at the macro level.

For now I'm just going to define my own macros and build the string there, but I think it would be a nice feature (and relatively cheap) to be able to control that behavior from the write_to_log virtual method.

cheers,
Rich

Today, I've found a bit time to work on it.
I've added FILE and LINE. FUNCTION is not supported everywhere. Unfortunately.

Cheers!

Thanks alot, really appreciated.

Concerning the function string, I use __PRETTY_FUNCTION__ with clang and __FUNCTION__ with vc++. Dunno about gcc, but I bet it supports one or the other. What compiler are you finding has missing support for one of these?

I believe this has gone in regression. With the current version of mlog, FILE and LINE are called in te templated write_message, which is called only in mlog.hpp.
