IOLogging.jl

A simple, thin package providing basic loggers for logging to IO. As the logging functionality from Base might change in the future, so will this package.

This package is registered with METADATA.jl, so you can just do ]add IOLogging to install the package.

julia> using Logging, IOLogging

julia> logger = IOLogger()

julia> oldGlobal = global_logger(logger)

julia> @info "Hello World!"

# prints this (with a current timestamp):
# [Info::2018-09-12T10:50:12.884]  Main@REPL[4]:1 - Hello World!

We can also pass our own destinations for Logging:

# default is stdout for everything above Info
julia> logger = IOLogger(Dict(Logging.Info => stderr, Logging.Error => devnull))

The same as above applies to FileLogger() as well, but instead of giving destination IO, we specify a destination file.

# default is default.log for everything above Info
julia> logger = FileLogger(Dict(Logging.Info => "info.log", Logging.Error => "error.log"))

For more information about the individual loggers, make sure to read ?IOLogger and ?FileLogger.

• Add custom log message formatting
• Add more tests
• Make decision on logging error catching (IOLogging.jl#20)
