Overview

Helper for processing loop markers in templates.

Handles collection} … {@end} blocks by:

  1. Extracting elements between markers

  2. Cloning for each collection item

  3. Filling with scoped data

Responsibility: Loop processing only Single Responsibility Principle: Does NOT parse or validate

Examples:

Process loop

helper = LoopHelper.new(context)
helper.process(start_marker, end_marker, document)

def process(start_marker, _end_marker, _document)
  # Resolve collection from current context
  resolver = @context.create_resolver
  collection = resolver.resolve(start_marker.collection)

  # Convert to array if needed
  Array(collection)

  # For now, we'll mark this as processed
  # Full implementation would clone elements between markers
  # and render each with scoped context
  #
  # This is a placeholder for the actual loop processing logic
  # which would need deep cloning and element insertion
