[PyX-devel] Comparing lengths

[David J. C. B. <be...@ve...>]

PyX Developers,

I've recently started using PyX to prepare a few presentation quality
graphics and I really like the quality of output it produces.

I've been trying to add some "layout-management" type classes so that I
can combine multiple images into larger layouts (such as grids/tables).=20
In so doing, I ran into the problem that instances of the unit.length()
class do not numerically compare, but simply have the default
"compare-by-id" behavior implemented by Python.  I don't like this at
all.  :)

I patched my own installation of PyX to ammend this, and am offering the
change here.  Can this go back into the distribution?

(in unit.length...)

    def __cmp__(self, other):
        l1 =3D tom(self)
        l2 =3D tom(other)
        if l1 <> l2: return cmp(l1,l2)
        return cmp(id(self), id(other))
