hi, thinks for this project, is it could render this
$$\begin{tikzpicture}[scale=1.0544]\small
\begin{axis}[axis line style=gray,
samples=120,
width=9.0cm,height=6.4cm,
xmin=-1.5, xmax=1.5,
ymin=0, ymax=1.8,
restrict y to domain=-0.2:2,
ytick={1},
xtick={-1,1},
axis equal,
axis x line=center,
axis y line=center,
xlabel=$x$,ylabel=$y$]
\addplot[red,domain=-2:1,semithick]{exp(x)};
\addplot[black]{x+1};
\addplot[] coordinates {(1,1.5)} node{$y=x+1$};
\addplot[red] coordinates {(-1,0.6)} node{$y=e^x$};
\path (axis cs:0,0) node [anchor=north west,yshift=-0.07cm] {0};
\end{axis}
\end{tikzpicture}$$

just like https://upmath.me/,

hello,
good work with developing a great plugin! I'm excited to try it out, however I am having trouble properly displaying the rendered formulas

I include the plugin in my react project just as you instructed here, however the formula does not render properly, for instance for the input

$$\sqrt{a}$$

I get this html

<span class="katex-display"><span class="katex"><span class="katex-mathml"><math>
<semantics>
	<mrow>
		<msqrt>
			<mrow>
				<mi>
					a
				</mi>
			</mrow>
		</msqrt>
	</mrow>
	<annotation encoding="application/x-tex">
		\sqrt{a}
	</annotation>
</semantics></math></span><span aria-hidden="true" class="katex-html"><span class="strut" style="height:0.8491550000000001em;"></span><span class="strut bottom" style="height:1.04em;vertical-align:-0.190845em;"></span><span class="base displaystyle textstyle uncramped"><span class="mord sqrt"><span class="sqrt-sign" style="top:-0.009155000000000024em;"><span class="style-wrap reset-textstyle textstyle uncramped">√</span></span><span class="vlist"><span style="top:0em;"><span class="fontsize-ensurer reset-size5 size5"><span style="font-size:1em;">​</span></span><span class="mord displaystyle textstyle cramped"><span class="mord mathit">a</span></span></span><span style="top:-0.769155em;"><span class="fontsize-ensurer reset-size5 size5"><span style="font-size:1em;">​</span></span><span class="reset-textstyle textstyle uncramped sqrt-line"></span></span><span class="baseline-fix"><span class="fontsize-ensurer reset-size5 size5"><span style="font-size:1em;">​</span></span>​</span></span></span></span></span></span></span>

And renders as

I am guessing stylesheet or client side javascript might be missing, I'm not entirely sure how to inclue all that using remarkable

Could you maybe share source of your blog or some more complete example?

Open curly brace (without a matching "closing" brace) will break the parse even when escaped.

I need something like this:

I'm getting the string from a json file like this:
$\\left\\{ \\begin{matrix}a + b + b = c \\\\ a + b = c\\end{matrix}\\right.$ won't parse

$\\left[ \\begin{matrix}a + b + b = c \\\\ a + b = c\\end{matrix}\\right.$ parses correctly

Changing the parser on lines 100 and 102 like this will make it work:

while (pos < max) {
      const char = state.src.charAt(pos);
      if (char === '{' && state.src.charAt(pos-1) !== '\\') {
        escapedDepth += 1;
      } else if (char === '}' && state.src.charAt(pos-1) !== '\\') {
        escapedDepth -= 1;
        if (escapedDepth < 0) { return false; }

I'm not very familiar with katex/math so i'm not sure if it would break something else, but i can make a PR with the change if that's ok!

$\colorbox{aqua}{$F=ma$}$ currently parses as two math chunks, $\colorbox{aqua}{$ and $}$, which is not correct.

Would you be willing to either add, or review a PR to add, proper brace handling so that this properly parses? For an example of how this can be done, see https://github.com/KaTeX/KaTeX/blob/master/contrib/auto-render/splitAtDelimiters.js

This bug is currently hampering the actual KaTeX documentation, which uses your plugin (!). See KaTeX/KaTeX#2280 (review)
