Question: could the child/overlay/aboutPage get the default content from the master with something like {{parent}} or {{master}}?
E.g.
const (
layout = `<title>{{block "metaTitle" .}}golang.org{{end}}</title><body>{{block "content"}}{{end}}</body>`
aboutPage = `{{define "metaTitle"}}Read all about Go - {{parent}}{{end}} {{define "content"}}About page content{{end}}`
)| const ( | |
| layout = `<title>{{block "metaTitle" .}}Welcome to golang.org{{end}}</title><body>{{block "content"}}{{end}}</body>` | |
| aboutPage = `{{define "metaTitle"}}Read all about Go on golang.org{{end}} {{define "content"}}About page content{{end}}` | |
| ) | |
| layoutTmpl, err := template.New("layout").Parse(layout) | |
| if err != nil { | |
| log.Fatal(err) | |
| } | |
| aboutPageTmpl, err := layoutTmpl.Overlay(aboutPage) | |
| if err != nil { | |
| log.Fatal(err) | |
| } | |
| if err := layoutTmpl.Execute(os.Stdout, nil); err != nil { | |
| log.Fatal(err) | |
| } | |
| if err := aboutPageTmpl.Execute(os.Stdout, nil); err != nil { | |
| log.Fatal(err) | |
| } | |
| // Output: | |
| // <title>Welcome to golang.org</title><body></body> | |
| // <title>Read all about Go on golang.org</title><body>About page content</body> |
