Code highlighter with preset, but customizable settings
Requires python 3.9
pip install keynote-highlight;- Copy code to clipboard;
- Run
keyhi; - Paste code to keynote;
- That's it!
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 work:
- 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.
