Hello Fellow Boosters,
I'd like to propose the design and development of a logging library
to be included in boost.
I've been thinking about what boost lacks, and this is one area of utility
that I think would benefit the boost community.
There are a great many examples of logging examples. Some designs I have
been thinking about are:
- based on iostreams coupled with the work being done with the format
by Samuel Krempp.
It would look like the following:
log << log_debug << log_format("%e %1") % "config file not found";
where there would be a log formatter that would have extra format
For example, the %e above could print the errno for a failed file
The log stream would support levels, and a default level. etc...
you would expect from a capable logger.
- Something similar to log4j. There is already a log4cpp, which is a port
of log4j to C++.
Some basic requirements:
- Some basic sink types (file, console, ring buffer...)
- Ability to log based on levels
- Ability to turn logging on/off dynamically
- Focus should be on good performance, and usability of the API. Make it
easy to setup and use logs.
- Useful, built in format specifiers.
- As fast a possible.
- Parameterizeable thread safety. Don't penalize programs that do not need
Is there any interest in such a library.
