Hi, I have uploaded the small logging object I proposed a few weeks ago with some changes following Andrey remarks.
And finally some implementation-regarded notes (though I understand this was just a draft, I couldn't hold myself, sorry :) ): 1. The logger is default-constructible from the user's code, but it seems that you intended to make it singleton.
fixed
2. logger::get_instance is not thread-safe - function-scope statics are used.
I think it's fixed now...
3. You should not define namespace bl = boost::logging; in the library code.
fixed
4. Element global operators should be in boost::logging namespace. They will be reachable via ADL.
ADL does not work with old compilers (msvc-6.0)
5. Each logging record involves std::stringstream (even not ostringstream) construction, formatted output copying, and destruction. I'm afraid, that would be a performance impact on the application.
fixed
6. I believe, some of the "Logging typedefs declarations" might have been hidden into the logger class and renamed. Some other names (like null_deleter) might have been hidden to an internal namespace.
Got to think about that. It also compiles with bjam v2 now on a 1.34.0. And it also compiles when added in multiple source files (hum). Here it is: (http://minilien.com/?2oscdAofQK) Just download it in boot_1_34_0 and unzip it. Next steps: Allow formatting per sink. Allow max level definition per sink. Allow severity/level definition. Regards, JD
