for the "puts each statement on one line based on the semicolons" part,
it's enough to pass the program through a simple sed script, *provided*
that each line not ending in a semicolon is not a complete line:

    sed -n  '/;\s*$/!{H}; /;\s*$/{H;g;s/\n//g;s/;\s*$//;p;s/.//g;h}'

(i guess this can be simplified.)
