Metropolis Theme

This theme draws inspiration from Matthias Vogelgesang's Metropolis beamer theme and has been modified by Enivex.

The Metropolis theme is elegant and suitable for everyday use. It is recommended to have Fira Sans and Fira Math fonts installed on your computer for the best results.

Initialization

You can initialize it using the following code:

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

#let s = themes.metropolis.register(aspect-ratio: "16-9", footer: self => self.info.institution)
#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."
• header: Content displayed in the header, defaulting to states.current-section-title, or it can be passed as a function like self => self.info.title.
• 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.
• footer-progress: Whether to show the progress bar at the bottom of the slide, defaulting to true.

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

Color Theme

Metropolis uses the following default color theme:

#let s = (s.methods.colors)(
  self: s,
  neutral-lightest: rgb("#fafafa"),
  primary-dark: rgb("#23373b"),
  secondary-light: rgb("#eb811b"),
  secondary-lighter: rgb("#d6c6b7"),
)

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

Slide Function Family

The Metropolis 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,
  // metropolis theme
  title: auto,
  footer: auto,
  align: horizon,
)[
  ...
]

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

---

#focus-slide[
  ...
]

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

---

#new-section-slide(short-title: auto, title)

Creates a new section with the given title.

slides Function

The slides function has the following parameters:

• title-slide: Defaults to true.
• outline-slide: Defaults to true.
• slide-level: Defaults to 1.

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 = (s.methods.enable-transparent-cover)(self: s)
