ctx-updater clj/s

(ctx-updater
  edges
  {:domino.graph/keys [db executed-events] :domino.core/keys [model] :as ctx})

Reducer that updates context with new values updated in ctx from handler of each edge. New values are only stored when they are different from old values.

In changed cases, the following keys are updated: ::changed-paths => queue of affected paths ::db => temporary relevant db within context ::change-history => sequential history of changes. List of tuples of path-value pairs

eval-traversed-edges clj/s

(eval-traversed-edges {:domino.graph/keys [changed-paths] :as ctx} graph)

(eval-traversed-edges {:domino.graph/keys [changes] :as ctx} graph origin)

Given an origin and graph, update context with edges.

When an node has been visited (as an input), it cannot be considered for an output
