Add question type checked by JavaScript functions

[seragunn]

Sample usage

<script src="/js/permutations.js"></script>
<script>
    function checkCycles(ans) {
        return (input) => {
            const ans_perm = new Permutation(ans);
            const in_perm = new Permutation().parseCycles(input);
            return in_perm.equals(ans_perm);
        }
    } 
    function checkShuffle(ans) {
        return (input) => {
            const ans_perm = new Permutation(ans);
            const in_perm = new Permutation().parseList(input);
            return in_perm.equals(ans_perm);
        }
    } 
</script>

using QuizQuestions

scriptq("checkCycles([2, 12, 3, 5, 4, 9, 8, 7, 6, 10, 1, 11])")

scriptq("checkShuffle([[1,8,12],[2,3,6,7,9],[4,10,11]])")

I was wondering how one injects a javascript snippet into the resulting HTML. You have this in your example:

"""

// in JavaScript
function threshold(t) {
    return (input) => {
        return input >= threshold;
    }
}

"""

Would there be an easy quarto equivalent?

If not, would some "question" form be useful with a show method that writes out the javascript code for mime-type text/html be useful?

I'm thinking something like:

struct Script{T} <: ???
txt::T
end

script(txt) = Script(txt)
function Base.show(io::IO, ::MIME"text/html", s::Script) 
println(io, "<script>")
println(io, s.txt) # ? escaped?
println(io, "</script>")
end

Maybe this isn't needed, but it might be helpful?

In Quarto you can put the script tags right into the file. I wouldn't try to have Julia try to programmatically output JavaScript that seems messy. The goal here is we have some external JavaScript code (for my current project, that's JavaScript code to represent permutations as cycles, lists, do multiplication, etc.). Plus that way you get syntax highlighting and debugging.

[seragunn]

Yes, so other than Quarto which lets you write <script> tags right into the markdown, you might need some kind of show method to output those tags.

However, I don't know who would be planning on using that. I'm only planning on using this for Quarto and I'm not sure how many other people use this package (or if they're using it outside of Quarto).

This looks great. I'll merge tomorrow and tag a new version unless you say hold off a bit. Thanks!
