Thanks. I think I understand what this code does. How do you want it
patched? Am I just writing my own alternative to sympy.latex? Are mainvar
and descending keyword arguments to sympy.latex or some other printing
function? I assume not everyone wants their polynomials in order of
descending p
I have an approach. It is fairly rough and not completely working:
In printing/latex.py
def latex(expr, inline=True, matstr=None, matdelim=None, \
mainvar=None, descending=False):
if inline:
if matstr is None:
matstr = 'smallmatrix'
if matdelim is None:
OK, I further hacked up compare_exponents and think I have a solution:
def compare_exponents(a, b):
print('')
print('a = %s' % a)
print('b = %s' % b)
print('mainvar = %s' % mainvar)
p1, p2, p3 =
OK, there is probably a cleaner way to implement this, but the following
seems to be working:
def _print_Add(self, expr):
args = list(expr.args)
if self._mainvar is not None:
mainvar = self._mainvar
def compare_exponents(a, b):
p1, p2, p3

The documentation suggests output li
On my machine (I am not running Windows, so I cannot be certain if it
will be the same for you), it makes a difference if I run isympy or
just import sympy in python or ipython. isympy gives unicode output.
Also run isympy --help. You can run isympy -p unicode (I don't know
how this is

I was thinking the same thing about making it work for all printers.
I will read the patch howto tomorrow and hopefully submit shortly after
that

Ok, excellent. If you need any help with git, just ask.

Try this:
In [18]: print u'\u03b1'
---> print(u'\u03b1')
α
Does it work? If it works, then your terminal seems to be working with
unicode, and we have a bug in sympy, that we should fix.

That fixed a problem I was having with isympy -p unicode not working
too.

Now this is odd…
I applied the patches (by hand; don’t know of a handy patch util for Windows)
and re-ran the test:

Sorry; Thunderbird glitched on me. Reposting, hopefully without
formatting oddnesses.

It might also be the font you are using. Make sure you are using a
Unicode font.

Yes, I don't want to install illegal windows to debug it, but I am now
downloading the 2.36GB windows7, that microsoft offers for free.
If you have some better idea how to provide me a testing environment,
let me know.
