• Summary: arraytypes.py is a bit byzantine
• Component: yt
• Milestone:
• Reporter: joishi
• Owner: mturk
• **Resolution: fixed
• Status: closed
• Created: 1197048248000000
• Description: why is numpy imported as na '''and''' obj? this is very confusing, especially for new users. in lagos, references to nT, na, and obj are scattered throughout. i assume this was to support some kind of easy switching between numpy and numarray, but it seems to me that the days of support for both are past. if we eliminate any trace of numarray, will nT still be necessary?

given Matt's comment in the header of arraytypes.py, perhaps this should be re-factored sooner rather than later?

• Newvalue: i did a quick grep for "obj\." in the yt src tree. doesn't look like there are too many places to replace it if we want to.

  [joishi@skronk src]$ ls

  lagos/EnzoRunType.py: self.outputs = obj.array(outputs) # Object array of EnzoHierarchies
  lagos/EnzoRunType.py: self.outputs = obj.array(self.outputs.tolist() + hierarchy)
  lagos/EnzoRunType.py: newOutputs = obj.array(self.outputs[:id].tolist() + self.outputs[id+1:].tolist())

• Newvalue: I have started fixing this in the unstable branch. (obj, for instance, should be completely eradicated.) I completely agree, arraytypes should largely be done away with, and any functions that actually do serve a purpose should be tossed into funcs.py.

The unstable branch will be moved over to the trunk early next week, since I have tagged release-0.2.1.
