Unicode Art#

This module implements ascii art using unicode characters. It is a strict superset of ascii_art.

class sage.typeset.unicode_art.UnicodeArt(lines=[], breakpoints=[], baseline=None)[source]#

Bases: CharacterArt

An Ascii art object is an object with some specific representation for printing.

INPUT:

  • lines – the list of lines of the representation of the ascii art object

  • breakpoints – the list of points where the representation can be split

  • baseline – the reference line (from the bottom)

EXAMPLES:

sage: i = var('i')                                                              # needs sage.symbolic
sage: unicode_art(sum(pi^i/factorial(i)*x^i, i, 0, oo))                         # needs sage.symbolic
 π⋅x
ℯ

>>> from sage.all import *
>>> i = var('i')                                                              # needs sage.symbolic
>>> unicode_art(sum(pi**i/factorial(i)*x**i, i, Integer(0), oo))                         # needs sage.symbolic

ℯ
sage.typeset.unicode_art.unicode_art(*obj, **kwds)[source]#

Return an unicode art representation

INPUT:

  • *obj – any number of positional arguments, of arbitrary type. The objects whose ascii art representation we want.

  • sep – optional 'sep=...' keyword argument (or 'separator'). Anything that can be converted to unicode art (default: empty unicode art). The separator in-between a list of objects. Only used if more than one object given.

  • baseline – (default: 0) the baseline for the object

  • sep_baseline – (default: 0) the baseline for the separator

OUTPUT:

UnicodeArt instance.

EXAMPLES:

sage: result = unicode_art(integral(exp(sqrt(x))/(x+pi), x))                    # needs sage.symbolic
...

If specified, the sep_baseline overrides the baseline of an unicode art separator:

sage: sep_line = unicode_art('\n'.join(' ⎟ ' for _ in range(5)), baseline=5)
sage: unicode_art(*AlternatingSignMatrices(3),                                  # needs sage.combinat sage.modules
