Klio logger for golang

This logger is meant to be used for building Klio commands. It writes logs decorated with control sequences interpreted by Klio. It doesn't filter or modify messages besides that.

Installation

go get github.com/g2a-com/klio-logger-go

Quick Start

If you don't want to use tags, or print to stderr use package-level functions:

package main

import (
	log "github.com/g2a-com/klio-logger-go"
)

func main() {
	log.Info("hello world")                  // Klio: [INFO] hello world
	log.Errorf("something went %s", "wrong") // Klio: [ERROR] something went wrong
}

In more complex cases, you may need to create custom logger:

package main

import (
	log "github.com/g2a-com/klio-logger-go"
)

func main() {
	l := log.StandardLogger()
	l = l.WithTags("foo", "bar")      // Klio prepends tags to log lines
	l = l.WithLevel(log.VerboseLevel) // WithLevel and WithTags return new logger instead of modyfing the original one

	l.Print("hello world")            // Klio: [VERBOSE][FOO][BAR] hello world
	l.Printf("hello %s", "world")     // Klio: [VERBOSE][FOO][BAR] hello world
}
