4 months ago You can try this workaround:
def BuildLongCodeBlock(*source_files):
code_files = [Code(f, insert_line_no=False).code for f in source_files]
code_lines = VGroup(*code_files).arrange(direction=DOWN, aligned_edge=LEFT, buff=0.5).scale(0.3)
window = SurroundingRectangle(
code_lines,
color=WHITE,
fill_color=WHITE,
corner_radius=0.2,
buff=0.3,
stroke_width=1,
stroke_color=WHITE,
)
return VGroup(window, code_lines)

2 months ago I have similar problems today
In the first time, I want to render a long TeX like the code. After making some changes(maybe removed \array{end}), the problem disappeared.
Then I changed tex_template.py, I met the same problems. I'm sure manim works well before changing it. Then I found I lost a line in _3b1b_preamble(\DisableLigatures{encoding = *, family = * }, which can not do the replacement in ctex), after adding it, manim works well again.

- Is this a new question or a comment about the proposed solution?
- Why are you referring to 3B1B's preamble when using ManimCE?
tex_templates.py, which includes 3B1B's preambleuwezi

2 months ago If it is a new problem you will need to provide the exact code you used - nobody will be able to reproduce and diagnose your problem from the error messages alone.
Better yet, come over to Discord for discussions. https://docs.manim.community/en/stable/faq/general.html?highlight=discord#where-can-i-find-more-resources-for-learning-manim
Long code blocks cause an error in _gen_chars
When using large blocks of code, I experienced an issue where i could not get a string to be accepted, after a bit of experimenting, it seems that after a certain point, indexing breaks.
Expected behavior
indexing should not break
How to reproduce the issue

I am unable to get details on latex, but this is a fresh install of manim community, so it should be whatever version / packages are included in the chocolaty package.
Line breaks and charracters seem to effect the indexing issue differently, but in the example code provided, removing the final
cwill let the script run.
