Hi,
After looking forward to a Boost Logging library for a while, I have been
playing with this idea.
This library http://channel.sourceforge.net/ which I believe the author is
working towards
including in Boost could be used to help write the logging library? Why
because it works both
acrosss local and remote machines and supports a asyncronous subscribing
machenism.
Boost.Logging could use Boost.Channel (hopefully) to allow doing of
something like below
somewhere along the lines of...
Boost.Logging Log;
// Some of these channels could be a built-in to Boost logging.
// add one channel at a time
Log.AddChannel(new SysLogOnLocal());
Log.AddChannel(new SysLogOnRemoteChannel("remote ip"));
Log.AddChannel(new SysLogLocalAndRemoteChannel(""remote ip");
Log.AddChannel(stdout);
Log.AddChannel(stderr);
Log.AddChannel(GuiWindow);
// add lots all together
Log.AddChannel(new LocalInfoChannel(), new LocalAndRemoteInfoChannel(), new
ErrorChannel(), new WarningChannel());
// writes to the info channel
Log.Write(LocalInfoChannel, "Hello World");
// writes to the info channel
Log.Write(LocalAndRemoteInfoChannel, "Hello World");
// writes to all the channels that the logger is subscribed to (nasty)...
Log.Write("Hello World");
The possibility and the power of this thing could be, well a powerful
logging library....
I suggest you look into this library during this design phase...
Thanks
Shams
