Metropolis Theme

This theme is inspired by the Metropolis beamer theme created by Matthias Vogelgesang and transformed by Enivex.

The Metropolis theme is elegant and suitable for daily use. For the best results, it is recommended to install the Fira Sans and Fira Math fonts on your computer.

Initialization

You can initialize the Metropolis theme using the following code:

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

#let s = themes.metropolis.register(s, 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 s = (s.methods.enable-transparent-cover)(self: s)
#let (init, slide, slides, title-slide, new-section-slide, focus-slide, touying-outline, alert) = utils.methods(s)
#show: init

#show strong: alert

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."
• header: Content to be displayed in the header, with the default being states.current-section-title. You can also pass a function like self => self.info.title.
• 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.
• footer-progress: Whether to show the progress bar at the bottom of the slide, with the default being true.

The Metropolis theme also provides an #alert[..] function that you can use with the #show strong: alert syntax.

Color Themes

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 the color theme using #let s = (s.methods.colors)(self: s, ..).

Slide Function Family

Metropolis theme provides a series of custom slide functions:

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

The title-slide reads information from self.info for display. You can also pass 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,
  margin: (top: 3em, bottom: 1em, left: 0em, right: 0em),
  padding: 2em,
)[
  ...
]

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

#focus-slide[

]

Used to draw attention. The background color is self.colors.primary-dark.
