Simple Theme

This theme is derived from Polylux, created by Andreas Kröpelin.

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

Initialization

You can initialize the Simple theme using the following code:

#import "@preview/touying:0.2.1": *

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

The register function takes parameters such as:

• aspect-ratio: The aspect ratio of the slides, either "16-9" or "4-3," with the default being "16-9."
• footer: Content to be displayed in the footer, with the default being []. You can also pass a function like self => self.info.author.
• footer-right: Content to be displayed on the right side of the footer, with the default being states.slide-counter.display() + " / " + states.last-slide-number.
• background: Background color, with the default being white.
• foreground: Text color, with the default being black.
• primary: Theme color, with the default being aqua.darken(50%).

Slide Function Family

The Simple theme provides a series of custom slide functions:

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

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

---

#title-slide[
  ...
]

Similar to centered-slide, this is just 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,
)[
  ...
]

This is the default ordinary slide function with a header and footer. The header is set to the current section, and the footer is as per your settings.

---

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

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