One possibility would be to match the exact file name. You can do so by
inspecting the `input_files` field of the global variable
`PANDOC_STATE`:

    local input_files = pandoc.List(PANDOC_STATE.input_files)
    if not input_files:includes('my-special-file.md') then
      return {}
    end

    -- rest of the script begins here.

Does that help?
