Go Log

This is Yet Another Logger for Go programs.

This is a logging package designed for local interactive shells running text based Go programs. To that end, this prints colorful log lines with customizable themes.

The color options for the log lines are NoColor (default), ANSIColor which limits the color codes to the standard 16 ANSI colors, and ExtendedColor which supports the 256-color palette of xterm and other modern terminal emulators. The theming engine supports defining colors using hex codes, supported by tomnomnom/xtermcolor.

This module is still a work in progress and will be extended and improved as I use it for other personal Go projects.

Usage

package main

import golog "git.kirsle.net/go/log"

var log golog.Logger

func init() {
    // Get a named logger and configure it. Note: you can call GetLogger any
    // number of times from any place in your codebase. It implements the
    // singleton pattern.
    log = golog.GetLogger("main")
    log.Configure(&golog.Config{
        Colors: golog.ExtendedColor,
        Theme: golog.DarkTheme,
    })
}

func main() {
    // The log functions work like `fmt.Printf`
    log.Debug("Running on %s", runtime.GOOS)
    log.Info("Hello, world!")
}
