Crapahalic is extremely experimental right now :) so dont even think about trying to do anything useful with it.

I started this page to present some common problems and workarounds experienced while developing/installing/using crapahalic, and so on, and so forth.

Problem #1: ImportError: No module named gnomecanvas

Solution:

gnome.canvas is deprecated, the new module is named gnomecanvas so that it doesn't depend on gnome. either replace all instances of "gnomecanvas" with "gnome.canvas" (ugly fix) or update your gnome-python2-canvas installation. (this entails upgrading to python2.4 on my system)

Problem #2: How do i get it to do anything??

Solution:

crapahalic parses the output of "halcmd show" in order to display the actual system configuration. ideally you could just do something like "sudo halcmd show | python halgui.py -" but this doesnt work yet. instead do "sudo halcmd show > poop.hal; python halgui.py poop.hal"

Problem #3: Crapahalic freezes when i load the output of sudo halcmd show mazak_rf.hal when passed via the command line.. Solution:

It works if you use "open" in the app.. needs to be investigated.
