I think the upcoming hopefully proposable Boost.Channel library can play a role in designing a flexible logging library, see: http://channel.sourceforge.net/ Also see my post here: http://article.gmane.org/gmane.comp.lib.boost.devel/156805 Thanks Shams -- "JD" <jean.daniel.michaud@gmail.com> wrote in message news:euu6g3$o4$1@sea.gmane.org...
Since I'm interested in having such a library in Boost, I'd be happy to participate.
It's what you did and you did well! Thank you!
- Nonetheless, I see a very interesting contribution from Michael Lacher. I'm not sure the mailing list is the right place to discuss them, but I don't see any discussion page on the wiki.
Concerning req id 3: Michael, I don't really get this statement. I think it's really to the library user (programmer) to decide which log shall be present or not. He's in charge of filtering the logs following the compilation configuration (debug or release). I don't think the library shall manage this by itself. Or maybe I did not get your point at all!
General Thoughts, third bullet: You say: "Logging: print log messages useful for the program user. They are needed to understand unexpected conditions during usage like: "file xyz not found", "directory baz is not readable".
I can't disagree more with this. IMO, logging is not at all a way to give information to the program user. In my mind, a logging library is intended only for debugging, journaling, auditing and performance measuring. Not a way to display error message or waiting message to the user. In my mind, these are totally different things. Please someone, give his POV on this, I think this is a major disagreement.
- Besides, Caleb Epstein propose the definition of channel as: Multiple named channels each with configurable "threshold" (e.g. error, warning, debug, etc)
Caleb, would you mind add a definition of channel on the wiki (http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Boost.Logging) and maybe add some requirements on this?
