pip install keynote-highlight

Motivation

Have you ever wanted to highlight your code for presentation with just one command from cli? Then this tool is for you!

Let's say, you want to make a presentation on Riemann sum and you want to add this code to your slides.

from typing import Callable, Iterator


def linspace(a: float, b: float, n=100) -> Iterator[tuple[float, float]]:
    """Linspace in pure python"""
    delta = abs((b - a) / n)
    x_i_min_1 = a
    x_i = a + delta
    yield x_i_min_1, x_i
    for _ in range(n):
        x_i_min_1 = x_i
        x_i += delta
        yield x_i_min_1, x_i
    yield x_i, b


def riemann_sum(f: Callable[[float], float], range_: tuple[float, float]) -> float:
    """
    Calculate Riemann sum
    
    :param f: function of a single argument
    :param range_: range of values this function is defined on
    :return: Riemann sum
    """
    res = 0
    for x_i_min_1, x_i in linspace(*range_):
        res += f((x_i+x_i_min_1)/2) * (x_i - x_i_min_1)
    return res

if __name__ == "__main__":
    print(riemann_sum(lambda x: x, (-4, 3)))

This is how it's going to look:

Features

• Select any language and styles to highlight code available in pygments;
• Change font size of your code;
• Load and save code straight to clipboard;
  • You can also your default cli code editor as a source of code instead of clipboard.
• For python you can change width of your code and apply black code formatter.
