ulogger

ulogger

A custom logger that can be configured with different output colors. It can also stream logs to a remote URL. Take a look at the documentation. It can also deep log an element using spew.

Usage

import "github.com/Unaxiom/ulogger"

func main() {
    log := ulogger.New()
    log.SetLogLevel(ulogger.DebugLevel) // Possible values are ulogger.DebugLevel (debug - least), ulogger.InfoLevel (info), ulogger.WarningLevel (warning), ulogger.ErrorLevel (error), ulogger.FatalLevel (fatal - highest), in ascending order, with ulogger.InfoLevel being the default
    log.RemoteAvailable = true // Defines whether logs need to the be streamed to the remote URL
    log.ApplicationName = "Temp Debugger" // Sets the applicaton name
    log.OrganizationName = "New org" // Sets the organization name that this build is licensed to
    log.LineNumber = false // Bool value sets if line number, function name, and the file name need to be printed to the console. Default is true
    ulogger.RemoteURL = "https://example.com" // Sets the remote URL where the log message needs to be sent via a POST request. If this is not set, and if log.RemoteAvailability is true, then the default URL is ""
}

Possible log levels

# Debug level logs
log.Debug(args ...interface{})
log.Debugf(format string, args ...interface{})
log.Debugln(args ...interface{})

# Info level logs
log.Info(args ...interface{})
log.Infof(format string, args ...interface{})
log.Infoln(args ...interface{})

# Warning level logs
log.Warning(args ...interface{})
log.Warningf(format string, args ...interface{})
log.Warningln(args ...interface{})

# Error level logs
log.Error(args ...interface{})
log.Errorf(format string, args ...interface{})
log.Errorln(args ...interface{})

# Fatal level logs
log.Fatal(args ...interface{})
log.Fatalf(format string, args ...interface{})
log.Fatalln(args ...interface{})

Deep logging

log.DebugDump(args ...interface{})
log.InfoDump(args ...interface{})
log.WarningDump(args ...interface{})
log.ErrorDump(args ...interface{})
log.FatalDump(args ...interface{})

Modification of output colors

log.InfoColor
log.InfoTimeColor
log.InfoMessageTypeColor
log.DebugColor
log.DebugTimeColor
log.DebugMessageTypeColor
log.WarningColor
log.WarningTimeColor
log.WarningMessageTypeColor
log.ErrorColor
log.ErrorTimeColor
log.ErrorMessageTypeColor
log.FatalColor
log.FatalTimeColor
log.FatalMessageTypeColor

Each of these values could be assigned an color from the package github.com/fatih/color.

Disabling remote logging

Remote logging can be disabled by setting log.RemoteAvailable to false.

Print function name, line number, and the file name

This can be done by setting log.LineNumber = true. The default instance when creating a new logger has it set to true. If these values aren't required, they can be hidden by setting this value to false.

Send log messages to custom URL

If log.RemoteAvailable is set to true, then log messages are sent via a POST request to the URL. In case the URL needs to be changed, then it can be done so by updating ulogger.RemoteURL to the appropriate URL string. These messages would be sent via goroutines, so the execution will not be blocked.
