#Config validation

Hi! Thanks for working on this. I think we should try and find the reference from the parent as seen here: https://git.drupalcode.org/project/drupal/-/merge_requests/13004/diffs#c...

That makes it actually dynamic, right now you just do the same, but then split in two which i think doesnt add much value.

Hello @bbrala,

Please check the code below and verify as I update those sections to use string_parts instead of string + regex:

core.entity_view_mode.*.*:
  type: config_entity
  label: 'Entity view mode settings'
  mapping:
    id:
      type: string_parts
      label: 'ID'
      # View mode IDs are in the form: entity_type.view_mode
      part_types:
        - type: string
          label: 'Entity type'
          pattern: '^[a-z0-9_]+$'
        - type: string
          label: 'View mode'
          pattern: '^[a-z0-9_]+$'

core.entity_form_mode.*.*:
  type: config_entity
  label: 'Entity form mode settings'
  constraints:
    FullyValidatable: ~
  mapping:
    id:
      type: string_parts
      label: 'ID'
      # Form mode IDs are in the form: entity_type.form_mode
      part_types:
        - type: string
          label: 'Entity type'
          pattern: '^[a-z0-9_]+$'
        - type: string
          label: 'Form mode'
          pattern: '^[a-z0-9_]+$'

core.entity_view_display.*.*.*:
  type: config_entity
  label: 'Entity display'
  mapping:
    id:
      type: string_parts
      label: 'ID'
      # Display IDs are in the form: entity_type.bundle.view_mode
      part_types:
        - type: string
          label: 'Entity type'
          pattern: '^[a-z0-9_]+$'
        - type: string
          label: 'Bundle'
          pattern: '^[a-z0-9_]+$'
        - type: string
          label: 'View mode'
          pattern: '^[a-z0-9_]+$'

core.entity_form_display.*.*.*:
  type: config_entity
  label: 'Entity form display'
  mapping:
    id:
      type: string_parts
      label: 'ID'
      # Form display IDs are in the form: entity_type.bundle.form_mode
      part_types:
        - type: string
          label: 'Entity type'
          pattern: '^[a-z0-9_]+$'
        - type: string
          label: 'Bundle'
          pattern: '^[a-z0-9_]+$'
        - type: string
          label: 'Form mode'
          pattern: '^[a-z0-9_]+$'

Let me know your thoughts.

Thanks!
