Simplify template usage by removing array

I am trying to simplify the template which I use to make it use a flatter data structure:

from

data := AppApp"test data", string"app1", "app2", "app3"


To:

data := AppApp"test data", string"app1", "app2", "app3"


i.e. Remove the array of App, but when I try it I get an error.

App

Here is the working version: https://play.golang.org/p/2THGtDvlu01

I tried to change the template to

range . -
range $i,$a := .Commandif gt $i 0 && end.end
end


But I got an error of type mismatched, any idea how to fix it?

package main

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

func main()
// Define a template.
const tmpl = `
echo &1

range $i,$a := .Commandif gt $i 0 && end.end

echo 2
`

// Prepare some data
type App struct
Data string
Command string

data := App"test data", string"app1", "app2", "app3"

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

// Execute the template with data
err := t.Execute(os.Stdout, data)
if err != nil
log.Println("executing template:", err)





Playground example

Gives the output

echo &1

app1 && app2 && app3

echo 2

Program exited.


If you remove the App from your code, you also need to remove the range used in the template.

App

range
