Small logger class

Question

I am looking for a small lightweight logging system in c++. I have found some existing frameworks but I don\'t need all of their features at this point in time. I primarily

Answer 1

I, as well as many others, also answered this question with some code.

This isn't really "ready" in all ways, but it could be easily modified:

https://gist.github.com/earonesty/977b14c93358fe9b9ee674baac5d42d7

Features:

• writing to the log doesn't block on i/o
• similar macros to other solutions (LOGE(blah << stream))
• prefers discarding log entries to slowing down
• lazy flushing
• header only, very small, stl classes only
• tested on osx/win/nix
• time format is configurable

Missing stuff:

• easy, flexible log formatting (predefining a macro would be fine)
• triggers have an interface but don't work yet
• microseconds aren't working yet

If anyone actually likes this solution in any way, lmk and I'll make a real repo out of it with tests, etc. It's pretty fast. Probably not as fast as speedlogger (a heavier feature complete library), but not sure.
