BNF

[Jedore]

Does marked support BNF, EBNF ?

Are you asking about code highlighting?

Marked doesn't do any highlighting but you can add a highlighter in the options

[Jedore]

Yeah, I use highlight.js, but met a problem.
And I use https://cdnjs.cloudflare.com/ajax/libs/marked/0.5.2/marked.min.js in my Django template file

let renderer = new marked.Renderer();
marked.setOptions({
    renderer: renderer,
    breaks: true,
    smartLists: true,
});
let html =  marked(text);

When I use BNF like

```bnf
name ::= identifier
```

Marked converts above markdown string to html with class attributes like

<pre><code class="language-bnf">name ::= identifier</code></pre>

but without hljs it seems to be invalid.
If set langPrefix to '', I got

<pre><code class="bnf hljs nginx"><span class="hljs-attribute">name</span> ::= identifier</code></pre>

why ?
Then I try set langPrefix to default value with null markdown string

```bnf
```

and I got

<pre><code class="bnf hljs"></code></pre>

So I don't understand ... Thanks @UziTech

but without hljs it seems to be invalid.

What seems to be invalid, the HTML that is output by marked?

Whatever hljs does with the HTML is not controlled by marked. This might be a question for highlight.js instead.

[Jedore]

uh... You're right, I thought hljs is controlled by Marked.
Thanks.
