getBuiltinFuncs problem

**Describe the bug**
The name parameter of the template built-in function has a scope problem

view/html.go
func (s *HTMLEngine) getBuiltinFuncs(name string) template.FuncMap {
funcs := template.FuncMap{
"part": func(partName string, binding interface{}) (template.HTML, error) {
nameTemp := strings.ReplaceAll(name, s.extension, "")
fullPartName := fmt.Sprintf("%s-%s", nameTemp, partName)
result, err := s.executeTemplateBuf(fullPartName, binding)
if err != nil {
return "", nil
}
return template.HTML(result), err
},
"current": func() (string, error) {
return name, nil
},
"partial": func(partialName string, binding interface{}) (template.HTML, error) {
fullPartialName := fmt.Sprintf("%s-%s", partialName, name)
if s.Templates.Lookup(fullPartialName) != nil {
result, err := s.executeTemplateBuf(fullPartialName, binding)
return template.HTML(result), err
}
return "", nil
},
// partial related to current page,
// it would be easier for adding pages' style/script inline
// for example when using partial_r '.script' in layout.html
// templates/users/index.html would load templates/users/index.script.html
"partial_r": func(partialName string, binding interface{}) (template.HTML, error) {
ext := filepath.Ext(name)
root := name[:len(name)-len(ext)]
fullPartialName := fmt.Sprintf("%s%s%s", root, partialName, ext)
if s.Templates.Lookup(fullPartialName) != nil {
result, err := s.executeTemplateBuf(fullPartialName, binding)
return template.HTML(result), err
}
return "", nil
},
"render": func(fullPartialName string, binding interface{}) (template.HTML, error) {
result, err := s.executeTemplateBuf(fullPartialName, binding)
return template.HTML(result), err
},
}
