Overview

Helper class to inherit from to ease the definition of attribute parsers in a PersonParser object, mostly used in for configuration loading.

Examples:

Example of usage:

class ExampleParser < Eco::API::Common::People::BaseParser
  def process
    @parsers.define_attribute("example") do |parser|
      parser.def_parser  do |str, deps|
        i = value.to_i rescue 0
        i +=5 if deps.dig(:sum_5)
        i
      end.def_serializer do |value|
        value.to_s
      end
    end
  end
end
pparser = Eco::API::Common::People::PersonParser.new
ExampleParser.new(pparser)
pparser.parse("example","3") # out: 3
pparser.parse("example","3", deps: {sum_5: true}) # out: 8
pparser.serialise("example, 8) # out: "8"
