highlight.js generates no HTML class name when "wrap: false" and "hljs: false" #111
Description
This issue is the behavior of lib/highlight.js.
In case of wrap: false:
If hljs: true, an HTML class name hljs appears in the output.
If hljs: false, no HTML class name appears in the output.
It is a lack of consistency.
I think an HTML class name highlight should appear as well as when wrap: true.
And also, the output for hljs: false lacks a PRE element and a CODE element.
That is, no HTML element appears around the output.
It is a lack of consistency, too.
Expected behavior
The output of util.highlight('alert("foobar")', {wrap: false}) is:
<pre><code class="highlight">alert("foobar")</code></pre>Actual behavior
alert("foobar")How to reproduce?
$ node
> const util = require('.')
undefined
> util.highlight('alert("foobar")', {wrap: false})
'alert("foobar")'
> util.highlight('alert("foobar")', {wrap: false, hljs: true})
'<pre><code class="hljs undefined">alert("foobar")</code></pre>'
>
