Bilog

bilog被设计为可以在需要性能，简单日志的场景下可以替换std log，它关注性能与轻量的实现。

Install

go get github.com/zbh255/bilog

Quick-Start

下面的所有示例代码都可在本repo的example文件夹中找到

Print-Time

func main() {
	logger := bilog.NewLogger(os.Stdout, bilog.PANIC)
	logger.Debug("hello world")
	logger.Trace("hello world!")
	logger.Flush()
}

OutPut

[DEBUG] 2022-01-24 12:53:29 hello world
[TRACE] 2022-01-24 12:53:29 hello world!

Print-Caller

func main() {
	logger := bilog.NewLogger(os.Stdout,bilog.PANIC,bilog.WithDefault(),bilog.WithCaller(0))
	logger.Trace("hello world!")
	logger.Debug("hello world!")
	logger.Flush()
}

OutPut

[TRACE] 2022-05-07 23:57:27 /Users/harder/Desktop/Git-Repo/github.com/zbh255/bilog/example/basic/caller/main.go:10 hello world!
[DEBUG] 2022-05-07 23:57:27 /Users/harder/Desktop/Git-Repo/github.com/zbh255/bilog/example/basic/caller/main.go:11 hello world!

No-Buffer

bilog默认使用双重缓冲区来缓冲需要打印的bytes，您可以像上面的例子那样使用Flush强制刷新Buffer，也可以禁用缓冲，如下所示。

func main() {
	logger := bilog.NewLogger(os.Stdout,bilog.PANIC,bilog.WithDefault(),
		bilog.WithLowBuffer(0),bilog.WithTopBuffer(0))
	logger.Trace("hello world!")
	logger.Info("hello world!")
}

OutPut

[TRACE] 2022-05-08 00:35:34  hello world!
[INFO] 2022-05-08 00:35:34  hello world!

事实上，您可以禁用缓冲也可以自行调节缓冲区的大小，使用跟如上示例一样的Api
