Install

go get github.com/goombaio/dag

You can also update an already installed version:

go get -u github.com/goombaio/dag

Example of use

// Create the dag
dag1 := dag.NewDAG()

// Create the vertices. Value is nil to simplify.
vertex1 := dag.NewVertex(nil)
vertex2 := dag.NewVertex(nil)
vertex3 := dag.NewVertex(nil)
vertex4 := dag.NewVertex(nil)

// Add the vertices to the dag.
dag1.AddVertex(vertex1)
dag1.AddVertex(vertex2)
dag1.AddVertex(vertex3)
dag1.AddVertex(vertex4)

// Add the edges (Note that given vertices must exist before adding an
// edge between them).
dag1.AddEdge(vertex1, vertex2)
dag1.AddEdge(vertex2, vertex3)
dag1.AddEdge(vertex2, vertex4)
dag1.AddEdge(vertex4, vertex3)
