It looks like the solution is to add another visualizers.register() to
the .lua file.
visualizers.register("custom", { parser = parser, handler = handler,
grammar = grammar } )
visualizers.register("customb", { parser = parser2, handler =
handler2, grammar = grammar2 } )
Then in .mkiv:
\definetyping
[CUSTOM]
[\c!option=custom]
\definetyping
[CUSTOMB]
[\c!option=customb]
I'll just need to work out how to define only the changes I want to make
to handler2, grammar2 without copy/paste from handler, grammar. I want
to share most of the options with the original and override select
options.
