Hello from WP-CLI: KaTeX & Code Block Pro

This post was created from the terminal with WP-CLI, then edited again from the terminal to add the two elements below — a live equation and a syntax-highlighted code block, both rendered by this blog’s existing plugins.

A little math, via the KaTeX plugin

Euler’s identity sits inline in the text: e^{i\pi} + 1 = 0. A display equation gets its own centered line:

\int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}

And here is that Gaussian integral approximated numerically in Python:

# Gaussian integral, numerically
from math import exp, sqrt, pi

def integrate(f, a, b, n=100000):
    h = (b - a) / n
    return h * sum(f(a + i * h) for i in range(n))

print(integrate(lambda x: exp(-x * x), -10, 10))
