Long Text with Manim

Question

While rendering long pieces of text using the community edition of the Manim library, I have noticed that information renders outside of the visible window for a rather unsatisfactory effect. I suspect that the root of the problem is the failure of Latex to ensure that text remains within the pdf boundaries. Is there a method to automatically wrap text? I do not want to manually specify line breaks as the text will no longer appear justified.

Here is a minimal example:

from manim import *


class Edge_Wise(Scene):
    def construct(self):
        text=Tex("\\text{First we conceptualize an undirected graph  ${G}$  as a union of a finite number of line segments residing in  ${\\mathbb{{{C}}}}$ . By taking our earlier parametrization, we can create an almost trivial extension to  ${\\mathbb{{{R}}}}^{{{3}}}$ . In the following notation, we write a bicomplex number of a 2-tuple of complex numbers, the latter of which is multiplied by the constant  ${j}$ .  ${z}_{{0}}\\in{\\mathbb{{{C}}}}_{{>={0}}}$  is an arbitrary point in the upper half plane from which the contour integral begins. The function  ${\\tan{{\\left(\\frac{{{\\theta}-{\\pi}}}{{z}}\\right)}}}:{\\left[{0},{2}{\\pi}\\right)}\\to{\\left[-\\infty,\\infty\\right)}$  ensures that the vertices at  $\\infty$  for the Schwarz-Christoffel transform correspond to points along the branch cut at  ${\\mathbb{{{R}}}}_{{+}}$ .}")
        text.scale(0.6)
        self.play(FadeIn(text))
        self.wait(1)
        self.play(FadeOut(text))

Answer 1

The \text environment you used does not wrap. It is intended to format text as text within math mode, and you don't need it when you are outside $...$. The following example gives you justified text:

class SquareToCircle(Scene):
    def construct(self):
        text=Tex("\\justifying {First we conceptualize an undirected graph  ${G}$  as a union of a finite number of line segments residing in  ${\\mathbb{{{C}}}}$ . By taking our earlier parametrization, we can create an almost trivial extension to  ${\\mathbb{{{R}}}}^{{{3}}}$ . In the following notation, we write a bicomplex number of a 2-tuple of complex numbers, the latter of which is multiplied by the constant  ${j}$ .  ${z}_{{0}}\\in{\\mathbb{{{C}}}}_{{>={0}}}$  is an arbitrary point in the upper half plane from which the contour integral begins. The function  ${\\tan{{\\left(\\frac{{{\\theta}-{\\pi}}}{{z}}\\right)}}}:{\\left[{0},{2}{\\pi}\\right)}\\to{\\left[-\\infty,\\infty\\right)}$  ensures that the vertices at  $\\infty$  for the Schwarz-Christoffel transform correspond to points along the branch cut at  ${\\mathbb{{{R}}}}_{{+}}$ .}")
        text.scale(0.6)
        self.play(FadeIn(text))
        self.wait(1)
        self.play(FadeOut(text))

Result:
