Support syntax highlighting in code blocks

[frankiejarrett]

AFAIK the only way to achieve a code block in readme.txt is to use the <pre> tag.

It would be nice to add support for a lang attribute so that syntax highlighting can be added when converting to markdown.

TXT

<pre lang="php">
function foo() {
    $bar = 'baz';
}
</pre>

Markdown

function foo() {
    $bar = 'baz';
}

Hmm, you can already use backticks:

`
code...
`

[frankiejarrett]

Oh wow. To my surprise this already works! 😄

By doing: <pre lang="php">

[frankiejarrett]

@kucrut That's what I thought too, but single backticks used to create code blocks were breaking the page when used in the FAQ tab on my WordPress.org plugin. Using them for inline code seems to work fine.

[frankiejarrett]

I'm going to reopen this because I do think there is some slight room for improvement.

It would be cleaner if <pre lang="php"> converted to ```php in markdown.

So <pre lang="php"> is part of the WP readme.txt “standard”? I don't see it mentioned on https://wordpress.org/plugins/about/readme.txt

Is it a hidden feature?

[frankiejarrett]

@westonruter Not sure if it's part of the "standard", but it does seem to work.

That's great. I was wondering how we could implement that.

@fjarrett let me know how #68 works for you.
