Selecting children/siblings/ancestors/descendants of a specific node

[rob-gordon]

Does anyone know if it is possible to use cytoscape selectors to select nodes which are children, siblings, ancestors, or descendants of a particular node?

Example 1

A selector which selects all nodes which are one edge away from a given node

An example selector, #a:sibling { background-color: yellow; }

Example 2

A selector which selects all the descendants of a node in a directed acyclic graph

An example selector, #d:descendants { background-color: yellow; }

I realize these could be expensive to compute and probably ambiguous in some contexts (I'm not a graph theory expert), but does anyone know if there has been an attempt to support selectors like these that I could try it out? Alternatively, is this functionality that could be added via a plugin?

Thanks for any advice or thoughts.

Topology is too expensive to be pragmatic for selectors. Cytoscape has a number of functions related to traversal that you can use: https://js.cytoscape.org/#collection/traversing

That's what I figured. If it were easy and inexpensive it would probably already be in Cy. Okay, I'll find another way to accomplish styling these using the traversal functions. Thanks for your help!
