Overview ¶
Package log provides basic logging mechanism.
You can log into physical file, but log rotation is not implemented, see https://12factor.net/logs => Ideally write to /dev/stderr|stdout|null and use something like https://github.com/logrotate/logrotate or https://github.com/agnivade/funnel for log post processing (funnel supports multiple targets, storing into files with rotation and compression) so let's not reinvent the wheel here.. TODO: - Enrich logger with methods of std logger for use in third party libs that needs it - If you get really bored some day: -- implement rolling files with https://github.com/natefinch/lumberjack -- allow writing into multiple files with io.MultiWriter
