Since GLUT+GHCi is problematic at best, after some very frustating experiments I decided on a client-server architecture.
$ vacuum-opengl-server & vaacum-opengl server started - press ESC to exit. listening on port 55961 $ ghci Prelude> :m + System.Vacuum.OpenGL Prelude System.Vacuum.OpenGL> view [1..5] Prelude System.Vacuum.OpenGL> view $ zip "foobar" [1..6] Prelude System.Vacuum.OpenGL> :m + Data.Set Prelude System.Vacuum.OpenGL Data.Set> view $ fromList [1..10]
- we need the graphviz executable (called "dot") being in the path.
- we need the server running
- the image generated by graphviz may be bigger than the maximum texture size your video card supports (eg. 2048). In this case you will see a white rectangle. TODO: handle this better.
