Relationships

After parsing, Mantou builds a relationship index so expressions can walk the graph cheaply.

Accessors#

• node.parent — the explicit parent reference
• node.children — direct children
• node.ancestors — parent chain to the root
• node.descendants — everything beneath
• node.neighbors — nodes connected by an edge
• node.incoming / node.outgoing — edges

Deep styling#

style node {
background: node.selected ? chili
  : node.ancestors.any(selected) ? bamboo
  : node.descendants.any(status == "failed") ? danger
  : cream
border: node.parent.selected ? scallion : border
}

Select Root or Backend below — descendants tint via ancestors.any(selected), and any branch containing a failed node turns danger.
