Ah, right. With `--standalone` pandoc is looking for a template that
matches the writer name. There isn't one of course. Just omit it.

Whoops, should have been `--write`. I'm cutting down on coffee, I guess
it shows. 😬

If you use `function Writer(doc, opts)`, then the variables are
available via `opts.variables`.

Do you mean an example of a classic custom writers? Pandoc has an
example built-in, it's available via

    pandoc --print-default-data-file=sample.lua

Classic writers are generally a bit easier (IMHO). I'd recommend new-
style writers if you either base the new writer on one that's already
included in pandoc, or if you want to make use of the `pandoc.layout`
module to get nicer looking output. Other than those cases, classic
writers are frequently the better choice.

Out of curiosity, what output format are planning to generate?

Cheers,
Albert
