Style julia> prompt

[fredrikekre]

Wouldn't it be nice to style the prompt in julia-repl? highglight.js marks the prompt as hljs-meta which is a tag that is used for misc other things too, for example.

However, top level meta, which for the julia-repl grammar is just the prompt, can be selected by

code.language-julia-repl > span.hljs-meta {
    // ...
}

(from highlightjs/highlight.js#3261 (comment)).

I suggest it should be colored with green just like the REPL.

Sounds good, but are we sure that we never get any other spans with hljs-meta?

[fredrikekre]

Yes, that is the only tag under the julia-repl grammar, everything else will be under plain julia: https://github.com/highlightjs/highlight.js/blob/1cb086b9509aa6af65e09a8936c5d93c9fe8178b/src/languages/julia-repl.js#L29-L38

Ah, yes, I see now. It puts a <span class="language-julia"> around the whole sub-language portion, so that CSS should be completely safe.
