Log

---

Log is a flexible logger for Golang applications. Inspired by xfxdev/xlog.

NOTICE Neither Fatal(f) nor Panic(f) functions exit the running code.

Installation

go get github.com/nszilard/log

Features

• Level logging

Support 7 different log levels, with an additional one having no level set. This makes it super easy to migrate from the built-in "log" package.

const (
	PanicLevel Level = iota
	FatalLevel
	ErrorLevel
	WarnLevel
	NoLevel
	InfoLevel
	TraceLevel
	DebugLevel
)

• Custom Log Layout

The layout can be modified according to the following table (you can use any combination):

Key	Maps to	Example
%y	Year
%M	Month
%d	Day
%h	Hours
%m	Minutes
%s	Seconds
%l	Log message
%L	Log level
%F	File path	/a/b/c/d.go
%f	File name	d.go
%i	Line in file
%D	%y/%M/%d
%T	%h:%m:%s

NOTICE: If you doesn't call 'SetLayout', it will use %D %T %L (%f:%i) ▶ %l by default.

• Thread safety

Log is protected by a mutex, so you can output logs in multiple goroutines.
