Use the same template with different param/variables in 1 page

I am using Go gin gonic for my web app. How do I use the same template file multiple times in 1 page with different variables passed to the template.

segment.tmpl

{{ define "segment" }}
    <div>{{ .Variable }}</div>
{{ end }}

layout.tmpl

<!DOCTYPE HTML>
<html>
<body>
    {{ template "segment . }} #with a variable 1
    {{ template "segment . }} #with different variable
    {{ template "segment . }} #another same template with another 
</body>
</html>

main.go

r.GET("/home/", func(c *gin.Context) {  
    tmpl := template.Must(template.ParseFiles("templates/layout.tmpl", "templates/product_add.tmpl", "templates/segment.tmpl")
    r.SetHTMLTemplate(tmpl)
    c.HTML(200, "layout", gin.H {
        "Variable1": "var1",
        "variable2": "var2",
    })
}

How do I use segment.tmpl multiple times in the page "home" and passing different kind of variables to the segment.tmpl? I have searched everywhere and have found nothing, the closest thing is template.Clone, but still couldn't find any examples of it.

Solution

You can pass any value as the "pipeline" to the template, it doesn't have to be the "dot", i.e. you could pass the result of a function call, or, in this case, the result of accessing a map's value.

{{ template "segment" .Variable1 }}

and then inside the template "segment" you can refer to the pipeline using the dot, i.e. {{ . }}.

segment.tmpl

{{ define "segment" }}
    <div>{{ . }}</div>
{{ end }}

layout.tmpl

<!DOCTYPE HTML>
<html>
<body>
    {{ template "segment .Variable1 }}
    {{ template "segment .Variable2 }}
    {{ template "segment .AnotherVariable }}
</body>
</html>
