1/ Writer
Using *--to=sample.lua* works when *--standalone* is not present and .
Otherwise I have this error: *Could not find data file 
templates/default.sample.lua*

Using *--writer=sample.lua* does not work. 
Error: "Unknown option --writer."

I now know why using "--to" did not work.

2/ Accessing variables in lua filter
I would like to have access to "variables" in lua filter.
Currently I have access to "metadata" when I use "*function Pandoc(doc) ... 
end*"
In the doc: https://pandoc.org/custom-writers.html#a-custom-html-writer, I 
saw this "*function Doc(body, meta, vars) ... end*" but it's never called 
in my tests.
I prefer not to use "*function Writer*" for now if possible.
Do you have any tips or working examples for that one?

Thanks
