HyadesCAUTION

LaTeX math as pure Unicode text. For terminals, code comments, emails, and everywhere rich formatting isn't a thing.

Every equation above is pure text -- you can select it and copy-paste it anywhere. The source is standard LaTeX.

What Is This?

Hyades takes standard LaTeX math like this:

$$
f(x) = \overbrace{\sum_{k=0}^{n} \frac{f^{(k)}(a)}{k!}
(x-a)^k}^{\mathit{Taylor polynomial}}
+ \underbrace{R_n(x)}_{\mathit{Remainder}}
$$

and renders it as multi-line Unicode text:

Taylor polynomial
╭───────────┴───────────╮
n      (k)
───    f   (a)         k
f(x) =  ╲     ───────── (x − a)  +   R (x)
╱⎽⎽      k!                   n
k = 0                       ╰───┬───╯
Remainder

or plain ASCII if you ask it to:

n      (k)
---    f   (a)         k
f(x) =  \     --------- (x - a)  + R (x)
/__      k!                 n
k = 0

It's a native CLI binary written in pure C. As such it is extremely fast and doesn't require any additional dependencies. Linux, MacOS, and Windows, and Web (WASM) are all supported out of the box.
