代码视频渲染器（CodeVideoRenderer）

示例

安装

pip install CodeVideoRenderer  

方法一

from CodeVideoRenderer import CodeVideo

CodeVideo(
    video_name="demo",
    code_string='print("Hello World")',
    language="python"
).render()

方法二

from CodeVideoRenderer import CodeVideo

code_to_render = '''from manim import *

class PiCalculation(Scene):
    def construct(self):
        # create circle and diameter
        radius = 2
        circle = Circle(radius=radius, color=BLUE)
        diameter_line = Line(circle.get_left(), circle.get_right(), color=YELLOW)

        # label radius and diameter
        radius_text = MathTex("r").next_to(circle.get_top(), UP)
        diameter_text = MathTex("d").next_to(diameter_line.get_top(), UP)

        self.play(Create(circle))
        self.play(Create(diameter_line))
        self.play(Write(radius_text), Write(diameter_text))
        self.wait(1)

        # show formula: pi = C / d
        formula = MathTex(r"\\pi = \\frac{C}{d}").to_edge(UP)
        self.play(Write(formula))
        self.wait(1)

        # red dot moves along circle to illustrate circumference
        dot = Dot(circle.get_right(), color=RED)
        self.add(dot)
        self.play(MoveAlongPath(dot, circle), run_time=4, rate_func=linear)

        # show final formula
        circumference_text = MathTex(r"C \\approx 2 \\pi r").next_to(circle, DOWN)
        self.play(Write(circumference_text))
        self.wait(2)

video = CodeVideo(
    video_name="pi_calculation_code",
    code_string=code_to_render,
    language="python",
    line_spacing=0.8
)

video.render()

注意事项

使用manim进行动画渲染，使用前请确保manim能够正常运行
短代码演示请使用方法一，长代码演示使用方法二
