Overview

Conflict resolver for text-based AST merging.

Uses content-based matching with destination-order preservation:

  1. Lines are matched by normalized content (whitespace-trimmed)
  2. Destination order is preserved (destination is source of truth for structure)
  3. Template-only lines are optionally inserted in template order relative to their matched anchors
  4. Freeze blocks are always preserved from destination

Examples:

resolver = ConflictResolver.new(template_analysis, dest_analysis)
result = MergeResult.new
resolver.resolve(result)

Constructor Details

#initialize(template_analysis, dest_analysis, preference: :destination, add_template_only_nodes: false, resolution_mode: :eager, unresolved_policy: nil) ⇒ ConflictResolver

Initialize the conflict resolver

Parameters:

  • template_analysis (FileAnalysis) —

    Analysis of template

  • dest_analysis (FileAnalysis) —

    Analysis of destination

  • preference (Symbol) (defaults to: :destination) —

    :destination or :template

  • add_template_only_nodes (Boolean) (defaults to: false) —

    Whether to add template-only lines
