Holmes

How to use

Debug level

package main

import github.com/quantfall/holmes

func main(){
  h := holmes.New("debug", "example")
  h.Info("%s using function: %s", "Output", "Info")
  h.Error("%s using function: %s", "Output", "Error")
  h.Debug("%s using function: %s", "Output", "Debug")
  h.FatalError("%s using function: %s", "Output", "FatalError")
}

Output:

YYYY/MM/DD HH:MM:SS example INFO: Output using function: Info
YYYY/MM/DD HH:MM:SS example ERROR: Output using function: Error
YYYY/MM/DD HH:MM:SS example DEBUG: Output using function: Debug
YYYY/MM/DD HH:MM:SS example PANIC: Output using function: FatalError

Info level

package main

import github.com/quantfall/holmes

func main(){
  h := holmes.New("info", "example")
  h.Info("%s using function: %s", "Output", "Info")
  h.Error("%s using function: %s", "Output", "Error")
  h.Debug("%s using function: %s", "Output", "Debug")
  h.FatalError("%s using function: %s", "Output", "FatalError")
}

Output:

YYYY/MM/DD HH:MM:SS example INFO: Output using function: Info
YYYY/MM/DD HH:MM:SS example ERROR: Output using function: Error
YYYY/MM/DD HH:MM:SS example PANIC: Output using function: FatalError

h.Debug was ignored because the log level is info.

Error level

package main

import github.com/quantfall/holmes

func main(){
  h := holmes.New("error", "example")
  h.Info("%s using function: %s", "Output", "Info")
  h.Error("%s using function: %s", "Output", "Error")
  h.Debug("%s using function: %s", "Output", "Debug")
  h.FatalError("%s using function: %s", "Output", "FatalError")
}

Output:

YYYY/MM/DD HH:MM:SS example ERROR: Output using function: Error
YYYY/MM/DD HH:MM:SS example PANIC: Output using function: FatalError

h.Debug and h.Info were ignored because the log level is error.

When using the function FatalError the program will close with an error code.
