# typst-theorems
An implementation of numbered theorem environments in
[typst](https://github.com/typst/typst).
Available as [ctheorems](https://typst.app/universe/package/ctheorems) in the
official Typst Universe.
Import with
```typst
#import "@preview/ctheorems:1.1.3": *
#show: thmrules
```
Alternatively, copy and import the [theorems.typ](theorems.typ) file to use in
your own projects.
### Features
- Numbered theorem environments can be created and customized.
- Environments can share the same counter, via same `identifier`s.
- Environment counters can be _attached_ (just as subheadings are attached to headings) to other environments, headings, or keep a global count via `base`.
- The depth of a counter can be manually set, via `base_level`.
- Environments can be ``'d and `@reference`'d.
## Manual and Examples
Get acquainted with `typst-theorems` by checking out the minimal example below!
You can read the [manual](manual.pdf) for a full walkthrough of functionality offered by this module; flick through [manual_examples](manual_examples.pdf) and its [typ file](manual_examples.typ) to just see the examples.
The [differential_calculus.typ](differential_calculus.typ) ([render](differential_calculus.pdf)) project provides a practical use case. _(Hastily translated from my notes written in LaTeX)_
### Preamble
```typst
#import "theorems.typ": *
#show: thmrules.with(qed-symbol: $square$)
#set page(width: 16cm, height: auto, margin: 1.5cm)
#set text(font: "Libertinus Serif", lang: "en")
#set heading(numbering: "1.1.")
#let theorem = thmbox("theorem", "Theorem", fill: rgb("#eeffee"))
#let corollary = thmplain(
"corollary",
"Corollary",
base: "theorem",
titlefmt: strong
)
#let definition = thmbox("definition", "Definition", inset: (x: 1.2em, top: 1em))
#let example = thmplain("example", "Example").with(numbering: none)
#let proof = thmproof("proof", "Proof")
```
### Document
```typst
= Prime numbers
#definition[
A natural number is called a #highlight[_prime number_] if it is greater
than 1 and cannot be written as the product of two smaller natural numbers.
]
#example[
The numbers $2$, $3$, and $17$ are prime.
@cor_largest_prime shows that this list is not exhaustive!
]
#theorem("Euclid")[
There are infinitely many primes.
]
#proof[
Suppose to the contrary that $p_1, p_2, dots, p_n$ is a finite enumeration
of all primes. Set $P = p_1 p_2 dots p_n$. Since $P + 1$ is not in our list,
it cannot be prime. Thus, some prime factor $p_j$ divides $P + 1$. Since
$p_j$ also divides $P$, it must divide the difference $(P + 1) - P = 1$, a
contradiction.
]
#corollary[
There is no largest prime number.
]
#corollary[
There are infinitely many composite numbers.
]
#theorem[
There are arbitrarily long stretches of composite numbers.
]
#proof[
For any $n > 2$, consider $
n! + 2, quad n! + 3, quad ..., quad n! + n #qedhere
$
