This looks amazing! I would love to have access to a tool like this for working on my current programming language project; is the tool available for download somewhere? I don't see anything about the editor in the Ohm repo[0].
Another cool thing would be to make an Ohm-to-Bison compiler; I'm not about to reimplement my whole language in Javascript, but I would love to prototype the grammar in the Ohm editor and then compile it down to Bison.
The grammar language looks unexciting, which is exactly what I want from a grammar language. Some kind of conversion is probably possible. But it looks like one of the really cool bits is being able to add actions to rules so easily, and that won't be as fluid in anything but Javascript.
