Outvar and context errors when used in Middleman (Patch included)

[joallard]

Related to #23, I took another approach, instead to remove extra options. I patched it on the fly in config.rb:

class ::PandocRuby
  module OptionPatch
    OPT_REMOVE_LIST = [:outvar, :context]

    # opts passed in. Recursively calls itself in order to handle hash options.
    def prepare_options(opts = [])
      opts.inject('') do |string, (option, value)|
        string + if value
                   create_option(option, value)
                 elsif option.respond_to?(:each_pair)
                   option = filter_option_hash(option)
                   prepare_options(option)

                 else
                   create_option(option)
                 end
      end
    end

    def filter_option_hash(hash)
      hash.reject do |k,v|
        OPT_REMOVE_LIST.include?(k)
      end
    end
  end
end

PandocRuby.prepend PandocRuby::OptionPatch

Hi @joallard! Thanks for this. I'm looking into all of this to try to understand the scope of the issue.

To help with repro:

On a tight scope:

Whenever options includes "outvar" or "context", exception.

On a wide scope:

Given a Middleman app, a source/document.md file, and in config.rb: set :markdown_engine, :pandoc
When I visit /document.html
Then I get the exception

(Maybe an allow list would fit better, I'm not sure)
