Package YAGL, or, Yet Another Golang Logger, extends the golang built-in log package with level control, and multiple output io.Writer support.

YAGL is NOT a drop-in replacement for the Golang built-in log package as log.Logger isn't exported as an interface (but a struct), and many symbols and behaviours might differ.

The Go tool chain has made everything so simple. To install the latest version, just do:

$ go get github.com/tabjy/yagl

Importing YAGL is same as importing other packages:

import "github.com/tabjy/yagl"

Then the packages is imported as yagl.

logger := yagl.StdLogger()
logger.Info("Great! YAGL is working perfectly!")

This would output something like

[INFO] 2017-12-20 02:57:18 Great! YAGL is working perfectly!

A well-explained example is also available.

The codes come together with inline documentation. If you like, a more human-friendly formatted documentation can be generated using following services.

6 logging level are provided:

• Trace: lowest logging level, ideal for printing variable values during development.
• Debug: anything that's too verbose to be included in "info" level.
• Info: detailed regular logger operation, basically equivalent to built-in log.Logger.Print.
• Warn: warning messages, which the application must be able to solve.
• Error: error messages, this indicates the corresponding subroutine would return with a error soon.
• Panic: something unexpected and unaccepted by design, the corresponding subroutine would throw a panic by calling this method.
• Fatal: highest logger level, catastrophic failure, the entire process would exit with error code 1 by calling this method.

• color code different logging levels.
• different output for different logging levels.
