在同一行中写入值

Question

I’ve the following code which works to generate the names One after another:

{{- range .File.apps}}

{{ .Name}}

{{- end}}

This prints

app1

app2

app3 

The problem is that I need to get it In the same line and not one after other

app1 app2 app3

When I try like following it remove the firsts entry and put only the last value. i.e. i'll get only app3

{{- range .File.apps}} {{ .Name}} {{- end}}

How can I do that?

Answer 1

The - character prevents new lines so adding a - before the closing }} should do the trick.

package main

import "fmt"
import "os"
import "text/template"

const temp = `
{{- range .Apps -}}
{{- .Name -}}
{{- end -}}
`

type file struct {
    Apps []app
}

type app struct {
    Name string
}

func main() {
    data := file{
        Apps: []app{
            app{"foo"}, 
            app{"bar"},
        },
    }
    t := template.Must(template.New("foo").Parse(temp))

    err := t.Execute(os.Stdout, data)
    if err != nil {
        fmt.Println(err.Error())
    }
}
