for loop should use xrange #2

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

The following patch to the trunk does the following:
- use xrange instead of arange (faster iterator)
- write the starting value only if necessary
- python's end value is IDL's end value + 1 (not + incval)
- when the end value ends with '-1', such as in 'for i = 0, v-1', translate it 
into 'for i in xrange(v)'

In fact, the end value depends on the incval sign.
This new patch correctly translate loops with negative strides.
