    You can switch between the HTML and MathML versions by locating this style snippet

    .katex .katex-html {
        display:none;
    }
    .katex .katex-mathml {
        display:inline-block;
    }

    in your browser’s dev tools and swapping the displays.

    @quintesse
    The parse errors are supposed to be there?
    Ah I guess you're just testing what exactly is supported and what not, right?
    Lucas Werkmeister
    @lucaswerkmeister
    yeah I just copied the equations from Wikipedia
    I’m actually surprised how many of them work
    Tako Schotanus
    @quintesse
    Do yu get the weird visual behaviour where the lower part of an equals sign is a slight gray color instead of black?
    Gavin King
    @gavinking
    yeah, ok, they look pretty decent
    Lucas Werkmeister
    @lucaswerkmeister
    @quintesse no
    Tako Schotanus
    @quintesse
    weird, here all equals sign are one part gray one part black, all the rest looks okay
    Gavin King
    @gavinking
    ok, very good, and what is that implemented in?
    Lucas Werkmeister
    @lucaswerkmeister
    JS
    Gavin King
    @gavinking
    @quintesse i don’t get that
    client-side js?
    Lucas Werkmeister
    @lucaswerkmeister
    yes
    but server-side also works according to KaTeX README
    Gavin King
    @gavinking
    well we want client-side i guess
    Tako Schotanus
    @quintesse
    blob
    Gavin King
    @gavinking
    so that should be really easy to integrate with ceylon doc
    Lucas Werkmeister
    @lucaswerkmeister
    @quintesse very odd, this uses web fonts (KaTeX_Main-Regular, KaTeX_Math-Italic, KaTeX_Size1-Regular here), should look the same for everyone
    Gavin King
    @gavinking
    @lucaswerkmeister send us a patch :)
    Lucas Werkmeister
    @lucaswerkmeister
    @gavinking don’t count on it, Bachelor’s Thesis has higher priority and still much to do :/
    Gavin King
    @gavinking
    heh
    Lucas Werkmeister
    @lucaswerkmeister
    oh, looks like KaTeX is actively developed too
    cases environment didn’t work above
    but apparently it was implemented recently
    Khan/KaTeX#278
    Khan/KaTeX@758bdba
    Gitter just doesn’t have it yet, I assume
    so that’s nice
    Gavin King
    @gavinking
    i don’ know latex at all

    KaTeX parse error: Expected 'EOF', got '\LaTeX' at position 6: \LaTeX̲: \LaTeX
    Tako Schotanus
    @quintesse
    are those parse errors supposed to be there?
    Lucas Werkmeister
    @lucaswerkmeister
    no, that’s why I’m experimenting in here, where no one’s supposed to see them!
    Tako Schotanus
    @quintesse
    :-p
    Well Big Brother is watching you!
    Lucas Werkmeister
    @lucaswerkmeister
    wtf, there’s a KaTeX\KaTeX, but no \LaTeX Khan/KaTeX#224
    buncha egoists ;)
