There’s a plugin I’d like to derive from
gvrender_core_svg.c, but I got stuck at
svg_begin_edge. My code needs the ID strings of the nodes connected by the edge. However, I don’t know how to acquire those from the
GVJ_t * passed into the function.
While I can get the endpoint
node_t * values with
aghead(obj->u.e), I don’t see a way to map those into an
obj_state_t * so I can grab their ID strings with
Am I missing something obvious, or is this difficult/impossible?
