Dewdrop Theme

This theme takes inspiration from Zhibo Wang's BeamerTheme and has been modified by OrangeX4.

The Dewdrop theme features an elegantly designed navigation, including two modes: sidebar and mini-slides.

Initialization

You can initialize it using the following code:

#import "@preview/touying:0.4.1": *

#let s = themes.dewdrop.register(
  aspect-ratio: "16-9",
  footer: [Dewdrop],
  navigation: "mini-slides",
  // navigation: "sidebar",
  // navigation: none,
)
#let s = (s.methods.info)(
  self: s,
  title: [Title],
  subtitle: [Subtitle],
  author: [Authors],
  date: datetime.today(),
  institution: [Institution],
)
#let (init, slides, touying-outline, alert, speaker-note) = utils.methods(s)
#show: init

#show strong: alert

#let (slide, empty-slide, title-slide, new-section-slide, focus-slide) = utils.slides(s)
#show: slides

The register function takes the following parameters:

• aspect-ratio: The aspect ratio of the slides, either "16-9" or "4-3," defaulting to "16-9."
• navigation: The navigation bar style, which can be "sidebar", "mini-slides", or none, defaulting to "sidebar".
• sidebar: Sidebar navigation settings, defaulting to (width: 10em).
• mini-slides: Mini-slides settings, defaulting to (height: 2em, x: 2em, section: false, subsection: true).
  • height: The height of mini-slides, defaulting to 2em.
  • x: Padding on the x-axis for mini-slides, defaulting to 2em.
  • section: Whether to display slides after the section and before the subsection, defaulting to false.
  • subsection: Whether to split mini-slides based on subsections or compress them into one line, defaulting to true.
• footer: Content displayed in the footer, defaulting to [], or it can be passed as a function like self => self.info.author.
• footer-right: Content displayed on the right side of the footer, defaulting to states.slide-counter.display() + " / " + states.last-slide-number.
• primary: Primary color, defaulting to rgb("#0c4842").
• alpha: Transparency, defaulting to 70%.

The Dewdrop theme also provides an #alert[..] function, which you can use with #show strong: alert using the *alert text* syntax.

Color Theme

Dewdrop uses the following default color theme:

#let s = (s.methods.colors)(
  self: s,
  neutral-darkest: rgb("#000000"),
  neutral-dark: rgb("#202020"),
  neutral-light: rgb("#f3f3f3"),
  neutral-lightest: rgb("#ffffff"),
  primary: primary,
)

You can modify this color theme using #let s = (s.methods.colors)(self: s, ..).

Slide Function Family

The Dewdrop theme provides a variety of custom slide functions:

#title-slide(extra: none, ..args)

title-slide reads information from self.info for display, and you can also pass in an extra parameter to display additional information.

---

#slide(
  repeat: auto,
  setting: body => body,
  composer: utils.side-by-side,
  section: none,
  subsection: none,
  // Dewdrop theme
  footer: auto,
)[
  ...
]

A default slide with navigation and footer, where the footer is what you set.

---

#focus-slide[
  ...
]

Used to draw attention, with the background color set to self.colors.primary.

Special Functions

#d-outline(enum-args: (:), list-args: (:), cover: true)

Displays the current table of contents. The cover parameter specifies whether to hide sections in an inactive state.

---

#d-sidebar()

An internal function used to display the sidebar.

---

#d-mini-slides()

An internal function used to display mini-slides.

slides Function

The slides function has the following parameters:

• title-slide: Defaults to true.
• outline-slide: Defaults to true.
• slide-level: Defaults to 2.

You can set these using #show: slides.with(..).

PS: You can modify the outline title using #(s.outline-title = [Outline]).

And the function of automatically adding new-section-slide can be turned off by #(s.methods.touying-new-section-slide = none).

#import "@preview/touying:0.4.1": *

#let s = themes.dewdrop.register(aspect-ratio: "16-9", footer: [Dewdrop])
#let s = (s.methods.info)(
  self: s,
  title: [Title],
  subtitle: [Subtitle],
  author: [Authors],
  date: datetime.today(),
  institution: [Institution],
)
#let (init, slides, touying-outline, alert, speaker-note) = utils.methods(s)
#show: init

#show strong: alert

#let (slide, empty-slide, title-slide, new-section-slide, focus-slide) = utils.slides(s)
#show: slides

= Title

== First Slide

Hello, Touying!

#pause

Hello, Typst!

Example

#import "@preview/touying:0.4.1": *

#let s = themes.dewdrop.register(
  aspect-ratio: "16-9",
  footer: [Dewdrop],
  navigation: "mini-slides",
  // navigation: none,

#let s = (s.methods.info)(
  self: s,
  title: [Title],
  subtitle: [Subtitle],
  author: [Authors],
  date: datetime.today(),

#let (init, slides, touying-outline, alert, speaker-note) = utils.methods(s)
#show: init

#show strong: alert

#let (slide, empty-slide, title-slide, new-section-slide, focus-slide) = utils.slides(s)
#show: slides

= Section A

== Subsection A.1

#slide[
  A slide with equation:

  $ x_(n+1) = (x_n + a/x_n) / 2 $
]

== Subsection A.2

#slide[
  A slide without a title but with *important* infos
]

= Section B

== Subsection B.1

#slide[
  #lorem(80)
]

#focus-slide[
  Wake up!
]

== Subsection B.2

#slide[
  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.
