Comment #2 on issue 1389 by [email protected]: pretty should have an
option to disable line wrapping
http://code.google.com/p/sympy/issues/detail?id=1389
From pretty.py's documentation now:
"""Prints expr in pretty form.
pprint is just a shortcut for this function.
Parameters
==========
expr : expression
the expression to print
wrap_line : bool, optional
line wrapping enabled/disabled, defaults to True
num_columns : bool, optional
number of columns before line breaking (default to None which reads
the terminal width), useful when using SymPy without terminal.
use_unicode : bool or None, optional
use unicode characters, such as the Greek letter pi instead of
the string pi.
full_prec : bool or string, optional
use full precision. Default to "auto"
order : bool or string, optional
set to 'none' for long expressions if slow; default is None
"""
So to fix the code to not have line wrapping:
x = sympy.Symbol('x')
print "<pre>"+ sympy.pretty(sympy.solve(x**5+x-1, x),
wrap_line=False)+"</pre>"
I think this issue can be closed, since pretty's options are now documented
(albeit the documentation is shown in pretty_print's documentation, but
pretty's documentation says "see pretty_print's documentation for options")
and there is an option to disable line wrapping.
