Code blocks exported from `src_foo` blocks know their language

[pdcawley]

Given some org source like this:

Executing src_bash{sudo rm -rf /} is generally considered a foolish thing to do.

the current version of ox-hugo exports the following:

Executing `sudo rm -rf /` is generally considered a foolish thing to do.

it would be immensely useful to me if the resulting markdown looked something like:

Executing <code class='inline inline-bash'>sudo rm -rf /</code> is generally considered a foolish thing to do.

which allows me to distinguish in my stylesheets between actual code and generic code-ish stuff.

Essentially I want to be able to write, say:

code.inline::before {
    color: initial;
    content: "｢";
}
code.inline::after {
    color: initial;
    content: "｣";
}

in my stylesheets and have only src_foo{...} blocks wrapped in corner brackets.

There's code to do pretty much exactly this in ox-html.el in the org source.

I do that for my blog with this small workaround below, because Hugo doesn't yet support inline code block rendering natively.

It's a 2-part implementation, and so I haven't baked it into ox-hugo.

Making inline-src-block export to a custom shortcode

https://github.com/kaushalmodi/.emacs.d/blob/7cb6c4286f5ec2a4cd0852f7d49a8ff1c28f98ae/setup-files/setup-hugo.el#L36-L51

The inline_src shortcode

{{- transform.Highlight .Inner (.Get 0) (.Get 1 | default "")
    | replaceRE `^<div class="highlight"><pre [^>]+>((.|\n)+)</pre></div>$`
                `<span class="inline-src chroma">${1}</span>`
    | replaceRE `<span class="line">((.|\n)+)</span>[ \n]*</code>`
                `${1}</code>`
    | safeHTML -}}

I had opened this issue on Hugo (https://github.com/gohugoio/hugo/issues/9442), we also almost had a solution that would allow the built-in highlight shortcode to do the inline code rendering, but that's stuck in limbo for a while.

ox-html calls a function that renders the code highlighting that the user uses in their emacs session and hardcodes those colors in CSS around the inline src blocks. So I didn't go that route. I wanted the syntax highlighting scheme to be consistent with the Chroma syntax highlighter used by Hugo.

Right. I'm not really looking to highlight inline code, just have something that can be styled with CSS independently of ~code~ fragments.

@pdcawley This is now implemented! You can find an example in https://github.com/kaushalmodi/ox-hugo/pull/578#issuecomment-1132902554.

@pdcawley Or you can see this update ox-hugo test: https://ox-hugo.scripter.co/test/posts/inline-code-blocks/#using-custom-css-for-inline-src-blocks

Aside.. looks like we triggered a bug in Hugo.. the smart quotes rendering done by GoldMark happens inside the HTML code elements too!
