Defined in:

Overview

Merges auto-detected template variables (from TemplateAnalyzer) with type/default/description metadata from @param comments (ParamParser).

Variables with @param get their declared type/default/description. Variables without @param are type-inferred from filters and control structures (e.g. money → number, for-loop → array, truthy if → checkbox). When inference is inconclusive, type falls back to “unknown”. Section variables (name == “section”) are excluded.

Usage:

merger = ParameterMerger.new(
  variables:  analyzer.external_variables,
  param_defs: param_parser.parse
)
merger.merge
# => [{ "name" => "title", "type" => "text", "default" => "My Card", "description" => "Card heading" },
#     { "name" => "color", "type" => "unknown", "default" => nil, "description" => nil }]
