Build extended options data from variant rows.

Supports Option1 through Option10 and optional slot mappings.

Arguments

• rows - List of CSV row maps for a single product
• opts - Keyword options:
  • :option_mappings - List of mapping configs from ImportConfig

Returns

Map with:

• base_price - Minimum variant price
• options - List of option data for each option found
• option_slots - Slot definitions if mappings provided

Examples

# Without mappings (standard import)
OptionBuilder.build_extended(rows)
# => %{
#   base_price: Decimal.new("22.80"),
#   options: [
#     %{position: 1, name: "Size", values: [...], modifiers: %{...}},
#     %{position: 2, name: "Cup Color", values: [...]},
#     %{position: 3, name: "Liquid Color", values: [...]}
#   ],
#   option_slots: []
# }

# With mappings (slot-based import)
mappings = [
  %{"csv_name" => "Cup Color", "slot_key" => "cup_color", "source_key" => "color"},
  %{"csv_name" => "Liquid Color", "slot_key" => "liquid_color", "source_key" => "color"}
]
OptionBuilder.build_extended(rows, option_mappings: mappings)
# => %{
#   base_price: Decimal.new("22.80"),
#   options: [...],
#   option_slots: [
#     %{slot: "cup_color", source_key: "color", label: "Cup Color", values: [...]},
#     %{slot: "liquid_color", source_key: "color", label: "Liquid Color", values: [...]}
#   ]
# }

Build options data from variant rows (legacy format).

Returns a map with:

• base_price: minimum variant price (Decimal)
• option1_name: name of first option (e.g., "Size")
• option1_values: list of unique values for option1
• option1_modifiers: map of value => price delta from base
• option2_name: name of second option (e.g., "Color")
• option2_values: list of unique values for option2

Examples

OptionBuilder.build_from_variants(rows)
# => %{
#   base_price: Decimal.new("22.80"),
#   option1_name: "Size",
#   option1_values: ["4 inches (10 cm)", "5 inches (13 cm)", ...],
#   option1_modifiers: %{"4 inches (10 cm)" => "0", "5 inches (13 cm)" => "5.00", ...},
#   option2_name: "Color",
#   option2_values: ["Black", "White", ...]
# }
