I use the Martini framework,I have some markdown file and I want render it as HTML in tmpl/html template.
The markdown file like this:
title: A Test Demo
##ABC
And the template file like this:
<title>{{name}}</title>
</head>
<h2>{{abc}}</h2>
<blockquote>
<p>{{xyz}}</p>
</blockquote>
</body>
I use the blackfriday parse the markdown and return []byte type,next step I wanna render the markdown file to this template and make each block to the right place,so how can I do this right way? Or use any way to do this better?
One way to achieve this is to use the Funcs method to add a custom function to the template function map. See the Functions section of the template package docs for more info.
Given a template file page.html, some writer w (probably an http.ResponseWriter), and some struct p with a field Body containing data to be put into a template field, you can do something like:
Define a function:
func markDowner(args ...interface{}) template.HTML {
s := blackfriday.MarkdownCommon([]byte(fmt.Sprintf("%s", args...)))
return template.HTML(s)
Add it to the template function map:
tmpl := template.Must(template.New("page.html").Funcs(template.FuncMap{"markDown": markDowner}).ParseFiles("page.html"))
Execute the template:
err := tmpl.ExecuteTemplate(w, "page.html", p)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
Then, in your template file, you can put something like:
{{.Body | markDown}}
And it will pass the Body through your markDowner function.
