slackreports

This is a basic tool to send at most one message every X seconds on a Slack channel using a webhook, useful to reduce the volume of messages when only the latest message is important. Only the latest message set by the Update method will be sent. Use the Stop method release associated resources.

Example

package main

import (
	"log"
	"time"

	"github.com/clement-fischer/slackreports"
)

func main() {
	// Replace using your previously configured webhook
	slackHook := "https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX"

	r := slackreports.NewReporter(slackHook, 3*time.Second)
	defer r.Stop()

	ticker := time.NewTicker(1 * time.Second)
	defer ticker.Stop()

	done := make(chan bool)
	go func() {
		time.Sleep(10 * time.Second)
		done <- true
	}()

	for {
		if r.E != nil {
			log.Fatalf("error: slackUpdater error field is not nil: %v", r.E)
		}
		select {
		case <-done:
			return
		case ts := <-ticker.C:
			message := ts.String()
			if err := r.Update(message); err != nil {
				log.Println(err)
			}
		}
	}
