Re: [Haskell-cafe] Re: tweak vacuum-* output

A little bit of topic, but why is the module Graphics.Ubigraph hidden in your package? I've been trying to use Ubigraph directly, and your module helped me a lot. (I just patched the cabal file to expose Graphics.Ubigraph as well) Is there a specific reason for it to be hidden? As far as I know, there is another wrapper for Ubigraph in Haskell, Hubigraph[1], but it's not on hackage. (licensing issues?) Your module contains all the basics, and should be enough in general.

Thanks! It looks better now!

PS: I actually knew about the oriented attribute, but I thought this might be something else. Anyway..

Thanks for the answer.

I see your point, that Ubigraph does some magic* to place vertices and edges. This makes me wonder, how they generate the binary tree demo: http://ubietylab.net/ubigraph/content/Demos/random_binary_tree.html Is there a way to disable this optimal graph layout determination process?

Best, Ozgur

Ozgur, I've just compared the way vacuum-ubigraph visualizes binary trees to the random_binary_tree demo and found that I had missed an important edge attribute called "oriented", it seems to produce the output you want.

I hope to upload the new package version soon, meanwhile you can do the following (assuming you use Linux):

cabal unpack vacuum-ubigraph patch -d vacuum-ubigraph-0.1.0.3/ -p 1 < vacuum-ubigraph-oriented.patch cd vacuum-ubigraph-0.1.0.3 cabal configure && cabal build && cabal install
