Controlling the new Logger (@debug messages)

General Usage
2

You need to establish a new logger, since they are immutable:


julia-1.0> logger=Logging.SimpleLogger(stderr,Logging.Debug)
Base.CoreLogging.SimpleLogger(Base.TTY(RawFD(0x0000000f) open, 0 bytes waiting), Debug, Dict{Any,Int64}())

julia-1.0> function foo(x)
           if x<5
           @debug "small"
           else
           @info "big"
           end
           end
foo (generic function with 1 method)

julia-1.0> Logging.with_logger(logger) do
           foo(10)
           foo(3)
           end
┌ Info: big
└ @ Main REPL[37]:5
┌ Debug: small
└ @ Main REPL[37]:3

You can swap out the one generally in use with global_logger (save the normal one with current_logger).
