SQLite docs-like figure

Question

I find SQLite docs very visual and I'd like to create one figure with the same format.

Also, if it's possible, I'd like to place the "conditionals" that are fulfilled to take that path:

Answer 1

As suggested by Jasper Habicht, the rail package did indeed have everything that I needed.

I was able to achieve the following:

via:

\begin{figure}
    \begin{rail}
        ([waterlogged=false] () | [waterlogged=true] 'WATERLOGGED' ) \\
        material
    \end{rail}
    \caption{Modifier concatenation}
\end{figure}

The only bad thing is that I need to compile it with the rail program every time I change something.
