[Haskell-cafe] Re: tweak vacuum-* output
The new version (0.2.0.1) is on Hackage.
vacuum-ubigraph now depends on Hubigraph, basic customization is now
possible, e.g.:
import System.Vacuum.Ubigraph
import Graphics.Ubigraph
myNodeStyle n = map (setColor #ff) $ defaultNodeStyle n
where
setColor color (VColor _) = VColor color
setColor _ s = s
myview = customView (defaultOptions { nodeStyle = myNodeStyle })
defaultServer
main = myview $ cycle [1..5]
Any feedback appreciated.

Thanks! It looks better now! PS: I actually knew about the oriented attribute, but I thought this might be something else. Anyway..

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.
