Part 002 Using A Map Of Strings With A Go Template

You can use templates with a map of strings. This allows a lot of flexibility for supplying the data. JSON can be read into a map like this.

An example (ex2.go):

package main

import (
	"os"
	"text/template"
)

const templ = `
My name is: {{.Name}}.

`

func main() {
	person := make(map[string]string, 1)
	person["Name"] = "Philip J. Schlump"

	t := template.New("simple-template")
	t, err := t.Parse(templ)
	if err != nil {
		panic(err)
		os.Exit(1)
	}

	err = t.ExecuteTemplate(os.Stdout, "simple-template", person)
	if err != nil {
		panic(err)
		os.Exit(1)
	}
}


To run this you can

$ go run ex2.go


To compile it and run it

$ go build ex2.go
$ ./ex2
