Closest I can get with a quick and dirty hack:
transform = Parslet::Transform.new do
rule(:factor => simple(:str), :plus => simple(:str2), :term =>
simple(:str3)) do
{ term: str, plus: str2, term2: str3 }
end
rule(:term => subtree(:x)) { x}
end
There's probably a better way; matching a subtree() like that is usually not
a good idea, because of the epic scope for it going catastrophically wrong.
