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:0.5.5": *
#import themes.metropolis: *

#import "@preview/numbly:0.1.0": numbly

#show: metropolis-theme.with(
  aspect-ratio: "16-9",
  footer: self => self.info.institution,
  config-info(
    title: [Title],
    subtitle: [Subtitle],
    author: [Authors],
    date: datetime.today(),
    institution: [Institution],
    logo: emoji.city,
  ),
)

#set heading(numbering: numbly("{1}.", default: "1.1"))

#title-slide()

The metropolis-theme in the theme accepts the following parameters:

• aspect-ratio: The aspect ratio of the slides, which can be "16-9" or "4-3", with a default of "16-9".
• align: The alignment of the content within the slides, with a default of horizon (horizontal alignment).
• header: The content displayed in the header of the slides, with a default that displays the current heading adjusted to fit the width (utils.display-current-heading(setting: utils.fit-to-width.with(grow: false, 100%))). Alternatively, you can provide a function like self => self.info.title to customize the header content.
• header-right: The content displayed on the right side of the header, with a default that shows the logo specified in self.info.logo.
• footer: The content displayed in the footer of the slides, with a default of an empty array []. You can customize it with a function, for example, to display the author's information: self => self.info.author.
• footer-right: The content displayed on the right side of the footer, with a default that shows the slide number and the total number of slides (context utils.slide-counter.display() + " / " + utils.last-slide-number).
• footer-progress: A boolean value indicating whether to display a progress bar at the bottom of the slides, with a default of true.
