There are multiple ways how to format the text content of your game. Notably Markdown with KaTeX.

Escaping

Generally, if you add text inside quotes " " (e.g. in Hint) you need to escape backslashes, but if you provide text inside a doc comment /-- -/ (e.g. in the Statement description) you do not!

This means for example you'd write /-- $\iff$ -/ but "$\\iff$".

Furthermore, inside Hint you need to escape all opening curly brackets as \{ since {h} is syntax for inserting a variable name h.

KaTeX

LaTeX syntax is provided trough the KaTeX library. KateX supports most but not all of latex and its packages. See supported.

Examples

Commutative diagrams

Here is an example of how to write a commutative diagram in KaTeX:


\begin{CD}
      A  @>{f}>> B @<{g}<< C    \\
  @V{h}VV    @V{i}VV   @V{j}VV \\
      D  @<{k}<< E @>{l}>> F    \\
  @A{m}AA    @A{n}AA   @V{p}VV \\
      G  @<{q}<< H @>{r}>> I
\end{CD}

$$
\begin{CD}
      A  @>{f}>> B @<{g}<< C    \\
  @V{h}VV    @V{i}VV   @V{j}VV \\
      D  @<{k}<< E @>{l}>> F    \\
  @A{m}AA    @A{n}AA   @V{p}VV \\
      G  @<{q}<< H @>{r}>> I
\end{CD}
$$

Again, note that inside a string like Hint/Introduction/Conclusion/etc. you need to escape \ and potentially {.

E.g. \begin as \\begin, \\ as \\\\ and inside a Hint, @>{f}>> as @>\{f}>>.

Truth Tables

KaTeX does not support the tabular environment. You can use the array environment instead.


\begin{array}{|c|c|}
  \hline
  P & ¬P \\
  \hline
  T & F  \\
  F & T  \\
  \hline
\end{array}

$$
\begin{array}{|c|c|}
  \hline
  P & ¬P \\
  \hline
  T & F  \\
  F & T  \\
  \hline
\end{array}
$$
