So we are slowly learning the things that should be on the first couple pages of the logging docs...

  1. simple example for one file programs, include an example of specifying output severity threshold. I'm with Antoine here on my expectations.

  2. example for multi-module, showing how a single logging destination causes logging to happen in all modules, at the same level (if that is the case, which I hope it is).

  3. Maybe a small discussion of log formatting should be next? So the user realizes he shouldn't do the message formatting himself?

  4. Then rotating logs for long-running programs.

And then the rest of the more feature-filled stuff. I agree logging needs to be full-featured, but many of the features are only necessary in complex environments, and simple stuff should be simple, if it can be, and those cases explained first. Hopefully a useful subset for simple cases can be described in 1-3 pages, and then the complex features after that. -------------- next part -------------- An HTML attachment was scrubbed...
