Edge attributes not processed by to_dot()

[mathtd]

The following code builds a graph with two vertices and two edges but when using to_dot() the attributes of the edges do not show up in the output file.

using Graphs

nnodes = 2
nedges = 2

vlist = Array(ExVertex, nnodes)
for i = 1:nnodes
    vlist[i] = ExVertex(i,"$i")
    vlist[i].attributes["height"] = i
end

elist = Array(ExEdge{typeof(vlist[1])}, nedges)

elist[1] = ExEdge(1, vlist[1], vlist[2])
elist[1].attributes["color"] = "blue"

elist[2] = ExEdge(2, vlist[2], vlist[1])
elist[2].attributes["color"] = "red"

g = graph(vlist, elist, is_directed = true)

to_dot(g,"temp.txt")

The content of temp.txt is

digraph graphname {
1   ["height"="1"]
2   ["height"="2"]
1 -> 2
2 -> 1
}

The vertices have their attributes but note the edges. Is that a bug or is there something wrong with my code?

Many thanks for any help!

Nevermind. I saw that pull request #206 fixes this.
