Logring is a Go package that records recently logged messages.
func Count() int
Count reports the total number of messages logged.
func Recent() []string
Recent returns the most recently logged messages.
func Writer(ringSize int) io.Writer
Writer returns an io.Writer suitable as an argument to log.SetOutput. It
saves the the most recent log entries, while also writing to Stderr. The
ringSize argument sets the maximum number of messages to keep.
package main
import (
"fmt"
"log"
"paulgorman.org/logring"
)
func main() {
log.SetOutput(logring.Writer(5))
for i := 0; i < 10; i++ {
log.Println("Logring test number", i)
}
for _, v := range logring.Recent() {
fmt.Println("Reprinting logring message:", v)
}
fmt.Println("Total errors logged:", logring.Count())
}
