Bad parsing

[kjellmf]

Having

digraph example {
    a -> b
    a -> c
    {rank=same; b;c}
}

will generate (dot2tex --preproc -tmath)

digraph example{
    a -> b ;
    subgraph c{
    b;
    c[fixedsize=true,width=0.75,label=" ",texlbl="$c$",height=0.5];

    graph [rank=same];
    }    a -> b ;
    a -> c ;
    a[fixedsize=true,width=0.75,label=" ",texlbl="$a$",height=0.5];
    c[fixedsize=true,width=0.75,label=" ",texlbl="$c$",height=0.5];
    b[fixedsize=true,width=0.75,label=" ",texlbl="$b$",height=0.5];

    graph [d2toutputformat=pgf];
}

Having

digraph example {
    a -> b;
    a -> c;
    {rank=same; b;c};
}

(the same but semicolons)

will produce "correct" (or at least expected)

digraph example{
    a -> b ;
    a -> c ;
    subgraph {
    b;
    c;

    graph [rank=same];
    }    a[fixedsize=true,width=0.75,label=" ",texlbl="$a$",height=0.5];
    c[fixedsize=true,width=0.75,label=" ",texlbl="$c$",height=0.5];
    b[fixedsize=true,width=0.75,label=" ",texlbl="$b$",height=0.5];

    graph [d2toutputformat=pgf];
}
