Seelog is a powerful and easy-to-learn logging framework that provides functionality for flexible dispatching, filtering, and formatting log messages. It is natively written in the Go programming language.

• Xml configuring to be able to change logger parameters without recompilation
• Changing configurations on the fly without app restart
• Possibility to set different log configurations for different project files and functions
• Adjustable message formatting
• Simultaneous log output to multiple streams
• Choosing logger priority strategy to minimize performance hit
• Different output writers
  • Console writer
  • File writer
  • Buffered writer (Chunk writer)
  • Rolling log writer (Logging with rotation)
  • SMTP writer
  • Others... (See Wiki)
• (In progress) Log message wrappers (JSON, XML, etc.)
• Global variables and functions for easy usage in standalone apps
• Functions for flexible usage in libraries

package main

import log "github.com/cihub/seelog"

func main() {
    defer log.Flush()
    log.Info("Hello from Seelog!")
}
