Is there any good wrapper available for level based logging in golang? If not, how should I go about implementing one myself?
What I want is pretty simple. I want a few functions e.g.
log.Error()
log.Info()
etc that display their outputs to stdout as well as save these in a log file (based on the level given to the program as commandline argument). How do I implement this wrapper?
Take a look at http://cgl.tideland.biz and there at the package "applog". It's working that way.
PS: The whole CGL is currently reworked and will soon be released with new features, but under a different name. ;)
I think seelog fits your requirements, and it seems to be pretty popular as it pops up often in log discussions. I never used it seriously, so I can't comment beyond that.
