Getting Started
Before you begin, make sure you have the Typst environment installed. If not, you can use the Web App or install the Tinymist LSP plugins for VS Code.
To use Touying, you just need to include the following in your document:
#import "@preview/touying:0.4.2": *
#let s = themes.simple.register()
#let (init, slides) = utils.methods(s)
#show: init
#let (slide, empty-slide) = utils.slides(s)
#show: slides
= Title
== First Slide
Hello, Touying!
#pause
Hello, Typst!
It's that simple! You've created your first Touying slides. Congratulations! π
Tip: You can use Typst syntax like #import "config.typ": * or #include "content.typ" to implement Touying's multi-file architecture.
Warning: The comma in #let (slide, empty-slide) = utils.slides(s) is necessary for the unpacking syntax.
More Complex Examplesβ
In fact, Touying provides various styles for slide writing. You can also use the #slide[..] syntax to access more powerful features provided by Touying.
Touying offers many built-in themes to easily create beautiful slides. For example, in this case:
#let s = themes.university.register(aspect-ratio: "16-9")
you can use the university theme. For more detailed tutorials on themes, you can refer to the following sections.
#import "@preview/touying:0.4.2": *
#import "@preview/cetz:0.2.2"
#import "@preview/fletcher:0.4.4" as fletcher: node, edge
#import "@preview/ctheorems:1.1.2": *
// cetz and fletcher bindings for touying
#let cetz-canvas = touying-reducer.with(reduce: cetz.canvas, cover: cetz.draw.hide.with(bounds: true))
#let fletcher-diagram = touying-reducer.with(reduce: fletcher.diagram, cover: fletcher.hide)
// Register university theme
// You can replace it with other themes and it can still work normally
#let s = themes.university.register(aspect-ratio: "16-9")
// Set the numbering of section and subsection
#let s = (s.methods.numbering)(self: s, section: "1.", "1.1")
// Set the speaker notes configuration
// #let s = (s.methods.show-notes-on-second-screen)(self: s, right)
// Global information configuration
#let s = (s.methods.info)(
self: s,
title: [Title],
subtitle: [Subtitle],

date: datetime.today(),
institution: [Institution],
)
// Pdfpc configuration
// typst query --root . ./example.typ --field value --one "<pdfpc-file>" > ./example.pdfpc
#let s = (s.methods.append-preamble)(self: s, pdfpc.config(

#let definition = thmbox("definition", "Definition", inset: (x: 1.2em, top: 1em))
#let example = thmplain("example", "Example").with(numbering: none)
#let proof = thmproof("proof", "Proof")
// Extract methods
#let (init, slides, touying-outline, alert, speaker-note) = utils.methods(s)

= Animation
== Simple Animation
We can use `#pause` to #pause display something later.
#pause
Just like this.
#meanwhile
Meanwhile, #pause we can also use `#meanwhile` to #pause display other content synchronously.
#speaker-note[
+ This is a speaker note.
+ You won't see it unless you use `#let s = (s.math.show-notes-on-second-screen)(self: s, right)`
]
== Complex Animation - Mark-Style
At subslide #utils.touying-wrapper((self: none) => str(self.subslide)), we can
use #uncover("2-")[`#uncover` function] for reserving space,
use #only("2-")[`#only` function] for not reserving space,
#alternatives[call `#only` multiple times \u{2717}][use `#alternatives` function #sym.checkmark] for choosing one of the alternatives.
== Complex Animation - Callback-Style
#slide(repeat: 3, self => [
#let (uncover, only, alternatives) = utils.methods(self)
At subslide #self.subslide, we can
use #uncover("2-")[`#uncover` function] for reserving space,
use #only("2-")[`#only` function] for not reserving space,
#alternatives[call `#only` multiple times \u{2717}][use `#alternatives` function #sym.checkmark] for choosing one of the alternatives.
])
== Math Equation Animation
Touying equation with `pause`:
#touying-equation(`
f(x) &= pause x^2 + 2x + 1 \
&= pause (x + 1)^2 \
`)
#meanwhile
Here, #pause we have the expression of $f(x)$.
#pause
By factorizing, we can obtain this result.
== CeTZ Animation
CeTZ Animation in Touying:
#cetz-canvas({
import cetz.draw: *
rect((0,0), (5,5))
(pause,)
rect((0,0), (1,1))
rect((1,1), (2,2))
rect((2,2), (3,3))
(pause,)
line((0,0), (2.5, 2.5), name: "line")
})
== Fletcher Animation
Fletcher Animation in Touying:
#fletcher-diagram(
node-stroke: .1em,
node-fill: gradient.radial(blue.lighten(80%), blue, center: (30%, 20%), radius: 80%),
spacing: 4em,
edge((-1,0), "r", "-|>", `open(path)`, label-pos: 0, label-side: center),
node((0,0), `reading`, radius: 2em),
edge((0,0), (0,0), `read()`, "--|>", bend: 130deg),
pause,
edge(`read()`, "-|>"),
node((1,0), `eof`, radius: 2em),
pause,
edge(`close()`, "-|>"),
node((2,0), `closed`, radius: 2em, extrude: (-2.5, 0)),
edge((0,0), (2,0), `close()`, "-|>", bend: -40deg),
)
= Theorems
== 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.
] <cor_largest_prime>
#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
$

Touying offers many built-in themes to easily create beautiful slides. For example, in this case:
#let s = themes.university.register(aspect-ratio: "16-9")
you can use the university theme. For more detailed tutorials on themes, you can refer to the following sections.
