# mdshare

Type markdown on the left, see it rendered on the right. The document is
compressed and stored in the URL itself, so sharing the page is just copying
the link: there is no server and nothing is uploaded.

## Math

Inline math like $e^{i\pi} + 1 = 0$ works, and so do display equations:

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

$$
\begin{pmatrix} a & b \\ c & d \end{pmatrix}
\begin{pmatrix} x \\ y \end{pmatrix}
=
\begin{pmatrix} ax + by \\ cx + dy \end{pmatrix}
$$

## Code

```python
import numpy as np

def gaussian(x, sigma=1.0):
    """The integrand from the equation above."""
    return np.exp(-x**2 / sigma**2)

x = np.linspace(-4, 4, 1000)
print(np.trapezoid(gaussian(x), x))  # ~ sqrt(pi)
```

```javascript
// The URL encoding used by this page
const payload = deflate(new TextEncoder().encode(text))
location.hash = base64url(payload)
```
