Templates

• Template golang package is used to help handle templates (i.e. html).

Template functions:

• Name: returns the name of the template
• Parse: Parse parses text as a template body for t.
• Lookup: returns the template with the given name that is associated with t.

Find many more functions in the official Golang package below Templates

package main

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

type Person struct {
        Name   string
}

const tmpl = `Hello {{.Name}}`

func main() {
    person := Person{
        Name:   "John Rambo",
    }

    t := template.New("Person template")

    t, err := t.Parse(tmpl)
    if err != nil {
            log.Fatal("Parse: ", err)
            return
    }

    err = t.Execute(os.Stdout, person)
    if err != nil {
            log.Fatal("Execute: ", err)
            return
    }
}

// outputs "Hello John Rambo"

Notice here that we declare a const variable of tmpl

• template.New allocates a new HTML template associated with the given one and with the same delimiters.
• The association, which is transitive, allows one template to invoke another with a `` action.
