Simple Theme

This theme originates from Polylux, created by Andreas Kröpelin.

Considered a relatively straightforward theme, you can use it to create simple slides and freely incorporate features you like.

Initialization

You can initialize it using the following code:

#import "@preview/touying:0.4.2": *

#let s = themes.simple.register(aspect-ratio: "16-9", footer: [Simple slides])
#let s = (s.methods.enable-transparent-cover)(self: s)
#let (init, slides) = utils.methods(s)
#show: init

#let (slide, empty-slide, title-slide, centered-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."
• 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.
• background: Background color, defaulting to white.
• foreground: Text color, defaulting to black.
• primary: Theme color, defaulting to aqua.darken(50%).

Slide Function Family

The Simple theme provides a variety of custom slide functions:

#centered-slide(section: ..)[
  ...
]

A slide with content centered, and the section parameter can be used to create a new section.

---

#title-slide[
  ...
]

Similar to centered-slide, this is provided for consistency with Polylux syntax.

---

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

A default slide with headers and footers, where the header corresponds to the current section, and the footer is what you set.

---

#focus-slide(foreground: ..., background: ...)[
  ...
]

Used to draw attention, it optionally accepts a foreground color (defaulting to white) and a background color (defaulting to auto, i.e., self.colors.primary).

slides Function

The slides function has the following parameter:

• slide-level: Defaults to 1.

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

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

#import "@preview/touying:0.4.2": *

#let s = themes.simple.register(aspect-ratio: "16-9", footer: [Simple slides])
#let s = (s.methods.enable-transparent-cover)(self: s)
#let (init, slides) = utils.methods(s)
#show: init

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

= Title
