I'm not sure what you're trying to do but I just started my own set
of macros today and two of the macros may interest you. One evaluates
python expressions, and the other executes python code.
So if you want to perform various math, and more, these are my results :
2+4 : 6
2*4 : 8
5^2 : 7
1^1 : 0
1|1 : 1
1|2|4 : 7
7&1 : 1
4&1 : 0
5**2 : 0
25 : 0
2*5**2 : 50
2*(5**25) : 596046447753906250L
2*(5**2) : 50
25**.5 : 5.0
import math
math.sqrt(25) : 5.0
address = '[EMAIL PROTECTED]'
user,domain = address.split('@')
user : 'tb'
domain : 'kaishaku.org'
You can probably do just about anything you want.
