Can we get the c++ equivalent of logback/slf4j? Avoiding string concat most of the time is the better option.

I haven't thought it out in detail, but the general idea is attached. It's just a proof of concept, so there are some obvious problems, but I don't see a flaw in the design. Since it's also just a single call, the in-place cost is small and is moved to the bodies of the templates, which can be just in one place, one per each combination of arguments (and the common instances of the template can be externed, so it really will be just one copy). The template code is relatively small, so I don't expect noticeable impact on compile time. Also, funnily enough, the generated code in the place of the call is one instruction shorter, because unlike printf() it does not need the terminating NULL for the vararg :). I expect it would be even possible to achieve such single in-place call even for the LOG( "P is " << p << " and b is " << b ) case, or even do this for string+string operation, which would turn it into the even better-looking LOG( "P is " + p + " and b is " b ) or LOG( "P is %1 and b is %2", p, b ), whichever would suit one's fancy (as in, both would be possible at the same time). It would require getting a bit more creative with argument and return types for the operator overloads, but that'd be hidden behind the scenes. -- Lubos Lunak l.lu...@suse.cz _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
