seelog Documentation

Seelog is a logging framework for Go that supports:

• Flexible Configuration: XML-based configuration that can be changed on the fly without restarting the application. Since v2.6, configuration can also be done via code.
• Multiple Output Streams: Simultaneous logging to various writers including Console, File, Buffered (Chunk), Rolling (with rotation), and SMTP.
• Advanced Formatting: Adjustable message formatting and support for log message wrappers like JSON and XML.
• Performance Optimization: Multiple logger priority strategies (e.g., sync, async loop, async timer, and adaptive) to minimize performance impact.
• Granular Control: Ability to set different log configurations for specific project files and functions.

To install Seelog in your Go project, use the following command. Ensure you have the Go development environment installed first.

go get -u github.com/cihub/seelog

For standalone applications, you can use Seelog's global variables and functions. It is important to call log.Flush() (typically via defer) to ensure all buffered log messages are written to their destinations before the application exits.

package main

import log "github.com/cihub/seelog"

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