How to conditionally set go template variables?
I want the output of the following code
https://play.golang.org/p/6e14hS2u1r
{
sweaters := Inventory{"", 17}
tmpl, err := template.New("test").
Parse(`{{$material := "something"}}{{if .Material}} {{$material :=
.Material}} {{end}}` +
"{{.Count}} items are made of {{$material}}.\n")
check(err)
err = tmpl.Execute(os.Stdout, sweaters)
check(err)
}
{
sweaters := Inventory{"wool", 17}
tmpl, err := template.New("test").
Parse(`{{$material := "something"}}{{if .Material}} {{$material :=
.Material}} {{end}}` +
"{{.Count}} items are made of {{$material}}.\n")
check(err)
err = tmpl.Execute(os.Stdout, sweaters)
check(err)
}
to be
17 items are made of something.
17 items are made of wool.
Using the exact same template. Is that possible?
Thanks
