Package seelog implements logging functionality with flexible dispatching, filtering, and formatting. To create a logger, use one of the following constructors: Example: The "defer" line is important because if you are using asynchronous logger behavior, without this line you may end up losing some messages when you close your application because they are processed in another non-blocking goroutine. To avoid that you explicitly defer flushing all messages before closing. Logger created using one of the LoggerFrom* funcs can be used directly by calling one of the main log funcs. Example: Having loggers as variables is convenient if you are writing your own package with internal logging or if you have several loggers with different options. But for most standalone apps it is more convenient to use package level funcs and vars. There is a package level var 'Current' made for it. You can replace it with another logger using 'ReplaceLogger' and then use package level funcs: Last lines do the same as In this example the 'Current' logger was replaced using a 'ReplaceLogger' call and became equal to 'logger' variable created from config. This way you are able to use package level funcs instead of passing the logger variable. Main seelog point is to configure logger via config files and not the code. So you can only specify formats and log rules by changing the configuration. The configuration is read by LoggerFrom* funcs. These funcs read xml configuration from different sources and try to create a logger using it. All the configuration features are covered in detail in the official wiki: https://github.com/cihub/seelog/wiki. There are many sections covering different aspects of seelog, but the most important for understanding configs are: After you understand these concepts, check the 'Reference' section on the main wiki page to get the up-to-date list of dispatchers, receivers, formats, and logger types. Here is an example config with all these features: This config represents a logger with adaptive timeout between log messages (check logger types reference) which logs to console, all.log, and errors.log depending on the log level. Its output formats also depend on log level. This logger will only use log level 'debug' and higher (minlevel is set) for all files with names that don't start with 'test'. For files starting with 'test' this logger prohibits all levels below 'error'. To learn seelog features faster you should check the examples package: https://github.com/cihub/seelog-examples It contains many example configs and usecases.
