Golang : Auto-generate reply email with text/template package



Tags : golang auto-reply-email text-template artificial-intelligence

Problem :

You have customers that ask question via email that sometimes bordering repetitive questioning or simply refused to read the Frequently Asked Question section. What should you do?

Solution :

Instead of cracking your head to write reply email each time, why not create an email auto-generator? It can be done easily with the text/template package. For this example, I will keep it simple. No artificial intelligence stuff yet( I'm working on it ) and auto email out the reply yet(shouldn't be hard to implement)

Here you go!

 package main

 import (
  "fmt"
  "log"
  "os"
  "text/template"
 )

 func main() {
  // Define a email template.
  const email = `
 Hey {{.Name}},
 {{if .Attended}}
 Have you read FAQ section yet?{{else}}
 It is a shame that you choose not to understand my first email reply!{{end}}
 {{with .Gift}}Thank you for your equiry about {{.}} by the way.
 {{end}}
 Best wishes,
 Gossie
 `

  // Prepare some data to insert into the template.
  type Recipient struct {
 Name, Gift string
 Attended bool
  }
  var recipients = []Recipient{
 {"Aunt Fonda", "dragon bone pottery set", true},
 {"Scott", "ancient map to the castle in the sky", false},
 {"Jessie", "", false},
  }

  // Create a new template and parse the letter into it.
  t := template.Must(template.New("email").Parse(email))

  // Execute the template for each recipient.
  for _, r := range recipients {
 err := t.Execute(os.Stdout, r)
 fmt.Println("----------------")
 if err != nil {
 log.Println("executing template:", err)
 }
  }

 }

Output :

Hey Aunt Fonda,

Have you read FAQ section yet?

Thank you for your equiry about dragon bone pottery set by the way.

Best wishes,

Gossie
