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, atomic=None)

Bases: sage.typeset.character_art.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')
sage: unicode_art(sum(pi^i/factorial(i)*x^i, i, 0, oo))
 π⋅x
ℯ

sage.typeset.unicode_art.unicode_art(*obj, **kwds)

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. 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.

OUTPUT:

UnicodeArt instance.

EXAMPLES:

sage: unicode_art(integral(exp(sqrt(x))/(x+pi), x))
    ⌠
    ⎮   √x
    ⎮  ℯ
    ⎮ ───── dx
    ⎮ x + π
    ⌡
