Overview

Profile definition DSL with full validation

Provides a clean, validated way to define custom comparison profiles. Catches errors at definition time with clear, actionable messages.

Examples:

Define a custom profile

Canon::Comparison.define_profile(:my_custom) do
  text_content :normalize
  comments :ignore
  preprocessing :rendered
end

Constant Summary collapse

VALID_DIMENSIONS =

All valid dimensions for XML/HTML comparison These must match MatchOptions::Xml::MATCH_DIMENSIONS

%i[
  text_content
  structural_whitespace
  attribute_presence
  attribute_order
  attribute_values
  element_position
  comments
].freeze
DIMENSION_BEHAVIORS =

Behaviors valid for each dimension Maps dimension name to array of valid behavior symbols

{
  text_content: %i[strict normalize ignore],
  structural_whitespace: %i[strict normalize ignore],
  attribute_presence: %i[strict ignore],
  attribute_order: %i[strict ignore],
  attribute_values: %i[strict strip compact normalize ignore],
  element_position: %i[strict ignore],
  comments: %i[strict ignore],
}.freeze
