Render templates

[khanzadimahdi]

Hi, recently I have seen your Golang tutorial. that's great.

I recommend rendering templates like the below:

func parseTemplate() (map[string]*template.Template, error) {
    templates := map[string]*template.Template{}

    layouts, err := filepath.Glob(fmt.Sprintf("%s/*%s", pathToTemplates, layoutSuffix))
    if err != nil {
        return templates, err
    }

    pages, err := filepath.Glob(fmt.Sprintf("%s/*%s", pathToTemplates, pageSuffix))
    if err != nil {
        return templates, err
    }

    for _, page := range pages {
        name := filepath.Base(page)

        filenames := make([]string, 0, len(layouts)+1)

        filenames = append(filenames, page)
        filenames = append(filenames, layouts...)

        t, err := template.New(name).ParseFiles(filenames...)
        if err != nil {
            return templates, err
        }

        templates[name] = t
    }

    return templates, nil
}

as you see, we don't need to double render templates! we find our page and render it with all layouts at once.

in the tutorial, we render the given page and then we render it with layouts!!!! I think we don't need the second step.
