I don't (yet) know if this matters, but the second function is about three
times faster than 'computeWidth'. It would be even five times as fast
without the 'split' command that accounts for the # Bug fix: 2012/06/05.
The 'expandtabs' function of Python automatically takes care of the
variable tab distances.
def computeWidth(s, tab_width):
# from leoGlobals.py
w = 0
for ch in s:
if ch == '\t':
w += (abs(tab_width) - (w % abs(tab_width)))
else:
w += 1
return w
def computeWidth2(s, tab_width):
return len(s.split("\n")[0].expandtabs(abs(tab_width)))
