# Eqn vs LaTeX

Tue, Jan 17, 2017Take the `LaTeX`

code:

`-1 \cdot \frac{1}{n}}\cup \{-1, \frac{1}{n}\}`

Do you know what this means?

- difficult parse visually.
- uses lots of hard-to-type symbols.

Not only that, `TeX`

by itself takes up 338.8 MB!

# Eqn

`-1 cdot 1 over n union left { -1 , 1 over n right }`

How’s that for readability!

This is eqn: a math preprocessor on the layout engine groff. By the same metric, groff takes up 8 MB.

And it works I promise!

Even if the math is nonsensical, isn’t it pretty!

You might already have groff/eqn on your machine! If not, take a look here.

This repo is my template for a simple eqn/groff project. Here’s what the pdf looks like.

Lastly, there is documentation for a groff macro system, and an in-depth guide for eqn!
