Bug Report for Cursor IDE - YAML syntax support problem#3046

# YAML Outline View Fails to Display Anchor and Reference Structure ## Description Cursor IDE's outline view fails to correctly display the structure of YAML files that contain anchors and references. This affects the navigation and understanding of complex YAML configurations. ## Steps to Reproduce 1. Create a YAML file with anchor and reference syntax, for example: ```yaml common: &common version: 1.0 environment: production service1: <<: *common name: service1 service2: <<: *common name: service2 ``` 2. Open the file in Cursor IDE 3. Open the outline view (usually on the left side) ## Expected Behavior The outline view should show the complete structure including: - common (with its properties) - service1 (with inherited properties from common) - service2 (with inherited properties from common) ## Actual Behavior The outline view: - Either shows incomplete structure - Or fails to properly display the inherited properties from anchors - Or shows incorrect nesting levels - Or completely misses some sections that use references ## Impact This issue significantly impacts the development experience when working with complex YAML configurations that use anchors and references for code reuse, making it difficult to: - Navigate through the file structure - Understand the complete configuration hierarchy - Verify the correct inheritance of properties ## Environment - OS: macOS - Cursor IDE Version: Latest (0.49.4 (Universal)) ## Additional Notes This is particularly problematic for configuration files that heavily rely on YAML's anchor and reference features for DRY (Don't Repeat Yourself) principles, such as: - Kubernetes configurations - Docker Compose files - CI/CD pipeline configurations - Infrastructure as Code templates
