Topic: How to display html in Jupyter with Julia?

Davi Sales Barreira (Apr 09 2021 at 19:05):

How do I display "html" in Jupyter Notebook with Julia? I've tried searching for a package, but didn't find any specific.

Mason Protter (Apr 09 2021 at 19:10):

You can just use the html string macro!

Thanks, Mason. Any other way using a function? I'm writing a package, so I guess using a macro is not the best way. I'm trying to write a wrapper to plot visualizations with D3.js. Do you think that using the "html" macro would be adequate?

Mason Protter (Apr 09 2021 at 19:21):

I'm not sure I understand the connection between not wanting to use a macro and developing a package

Mason Protter (Apr 09 2021 at 19:22):

But to answer your question, yes there is a HTML function that the html string macro will use during parse time.

julia> HTML("hi") == html"hi"
true

Mason Protter (Apr 09 2021 at 19:25):

But in case there's a confusion here, there is no reason not to use macros in package development. In many cases, a macro (when applicable) can be more efficient than a function, like with the regex string macros, because they allow the regex to be compiled at macroexpansion instead of at runtime

Davi Sales Barreira (Apr 09 2021 at 19:38):

Thanks Mason! It was a thing I read somewhere. Although I probably misinterpreted.

Mason Protter (Apr 09 2021 at 19:52):

Probably the advice you heard was that many users first learning about metaprogramming overuse it, and that beginners should not be encouraged to create their own macros

Mason Protter (Apr 09 2021 at 19:53):

I think that while it's true that many new metaprogrammers will overdo it, I think that's a good thing! Doing something a lot (even when it's not necessary) is the fastest way to learn how to do something well.

@Davi Sales Barreira If your string needs to be informed by the Julia processing context, you might also want to look at HypertextLiteral.jl

@Clark C. Evans that's an awesome package! Thanks for pointing out.
