Overview

Handles attaching remarks (comments) to model elements after parsing.

NOTE: Post-processing remark attachment has inherent limitations for scope-based matching. Remarks with simple tags (like “WR1”) inside scopes (TYPE, ENTITY, etc.) cannot be perfectly matched without parsing context. This implementation prioritizes:

  1. Exact path matches (e.g., “schema.entity.WR1”)

  2. Proximity-based matching for simple tags

  3. NOT creating spurious schema-level items for ambiguous tags

Constant Summary collapse

CHILD_COLLECTION_ATTRIBUTES =

Child collection attributes to walk when traversing model elements. These are the named collections on model elements (e.g., entity.attributes, schema.entities, function.parameters). Extracted to a constant to avoid duplication between calculate_children_end_line and collect_children.
