scribe

scribe lets you write more readable math by defining an ASCII-based notation.
The notation aims to be intuitive and resemble its rendered form visually.
Large parts of it are derived from asciimath.

All you need to do is to import the following.

#import "@preview/scribe:0.2.0": *
#show: scribe

With scribe you can write 
$Ff * (f @ g)(x) \\ {0} -= +-1 .. (mod n)$

instead of
$cal(F) dot.op (f compose g)(x) without {0} equiv plus.minus 1 quad (mod n)$

It is possible to only use a subset of the features.

#import "@preview/scribe:0.2.0": *
#show: scribe.with("operations", "logicals")

$ a * b = 0 vv a +- b = 3 $

If you need to keep the namespace clean, you can import only the features you use.

#import "@preview/scribe:0.2.0": scribe, operations, logicals
#import operations: *
#import logicals: *

#show: scribe.with("operations", "logicals")

$ a * b = 0 vv a +- b = 3 $
