Using CodeCogs editor to process Latex formula markup
This plugin block sends the Latex-style markup to the CodeCogs online equation editor. For example,
=for LatexFormula :headlevel(2) :caption<Simple formula>
\begin{align*}
\sum_{i=1}^{k+1} i^{3}
&= \biggl(\sum_{i=1}^{n} i^{3}\biggr) + i^3\\
&= \frac{k^{2}(k+1)^{2}}{4} + (k+1)^3 \\
&= \frac{k^{2}(k+1)^{2} + 4(k+1)^3}{4}\\
&= \frac{(k+1)^{2}(k^{2} + 4k + 4)}{4}\\
&= \frac{(k+1)^{2}(k+2)^{2}}{4}
\end{align*}
The RakuDoc v2 specification has a builtin block =formula and the recommended formula markup is Latex. This plugin overrides the formula template, effectively aliasing it to LatexFormula. So the following will work too:
=for formula :caption<Fabulous identity>
e^{i\pi}+1=0
