a very simple Go's struct template parser
- Install
$ go get github.com/Bhinneka/got- Parse Template to
stdio
you can create a custom function inside your template:
funcMaps := template.FuncMap{
"toUpper": func(v string) string {
return strings.ToUpper(v)
},
}example:
// Person struct
type Person struct {
ID string
Name string
}
func main() {
data := Person{
ID: "1",
Name: "Wuriyanto",
}
tmpl := `
Hello
Your ID : {{ .ID }}
Your Name : {{ toUpper .Name }}
`
funcMaps := template.FuncMap{
"toUpper": func(v string) string {
return strings.ToUpper(v)
},
}
err := got.Parse(tmpl, data, os.Stdout, funcMaps, got.ParseTemplateText)
if err != nil {
fmt.Println(err)
}
//output :
//Hello
//Your ID : 1
//Your Name : WURIYANTO
}- Parse template file
my_template.tmpl
<html>
<head>
<title>Example</title>
</head>
<body>
<h1>{{ .OrderID }}</h1>
<ul>
{{- range $item := .Items}}
<li>{{ $item }}</li>
{{- end }}
</ul>
</body>
</html>Order.go struct
// Order struct
type Order struct {
OrderID string
Items []string
}Parse this go struct to my_template.tmpl file
func main() {
myOrders := Order{
OrderID: "00881119977",
Items: []string{"Coffee mix", "Tea", "Mendoan", "Gorengan", "Onde-onde"},
}
var target strings.Builder
err := got.Parse("my_template.tmpl", myOrders, &target, nil, got.ParseTemplateFile)
if err != nil {
fmt.Println(err)
}
fmt.Println(target.String())
//output:
// <html>
// <head>
// <title>Example</title>
// </head>
// <body>
// <h1>00881119977</h1>
// <ul>
// <li>Coffee mix</li>
// <li>Tea</li>
// <li>Mendoan</li>
// <li>Gorengan</li>
// <li>Onde-onde</li>
// </ul>
