Custom pretty printer pass option to buff-imp-<mycustomformat>.lua

Custom pretty printer pass option to buff-imp-<mycustomformat>.lua

[Lorenz]

I'm customizing a pretty printer and referencing the buff-imp-lua.lua
and buff-imp-lua.mkiv files.  

I'd like to add a conditional to the .lua file say buff-imp-custom.lua. 
What is a good way to pass an option from my .tex file to conditionally
format with the pretty printer?   I'd like to use the same
buff-imp-custom.lua and .mkiv pairs of files instead of creating
multiple files.

The .mkiv file defines e.g.:

    \definetyping
        [CUSTOM1]
        [\c!option=custom]

I'd like to add say CUSTOM2 but pass an option that would be visible to
the same buff-imp-custom.lua file.  Perhaps something like this?:

    \definetyping
        [CUSTOM2]
        [\c!option=custom,<option visible to same lua file as CUSTOM1?>]


Thanks

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.
