Sections and Subsections

Structure​

Similar to Beamer, Touying also has the concept of sections and subsections.

Generally, level 1, level 2, and level 3 headings correspond to section, subsection, and title, respectively, as in the dewdrop theme.

#import "@preview/touying:0.4.0": *

#let s = themes.dewdrop.register()
#let (init, slides) = utils.methods(s)
#show: init

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

= Section

== Subsection

=== Title

Hello, Touying!

However, often we don't need subsections, and we can use level 1 and level 2 headings to correspond to section and title, as in the university theme.

#import "@preview/touying:0.4.0": *

#let s = themes.university.register()
#let (init, slides) = utils.methods(s)
#show: init

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

= Section

== Title

Hello, Touying!

In fact, we can control this behavior through the slide-level parameter of the slides function. slide-level represents the complexity of the nested structure, starting from 0. For example, #show: slides.with(slide-level: 2) is equivalent to the section, subsection, and title structure; while #show: slides.with(slide-level: 1) is equivalent to the section and title structure.

Numbering​

To add numbering to sections and subsections, we simply use:

#let s = (s.methods.numbering)(self: s, section: "1.", "1.1")

This sets the default numbering to 1.1, with the section corresponding to 1..

Table of Contents​

Displaying a table of contents in Touying is straightforward:

#import "@preview/touying:0.4.0": *

#let s = themes.simple.register()
#let (init, slides, alert, touying-outline) = utils.methods(s)
#show: init

#let (slide, empty-slide) = utils.slides(s)
#show: slides.with(slide-level: 2)

= Section

== Subsection

=== Title

==== Table of contents

#touying-outline()

Where the definition of touying-outline() is:

#let touying-outline(enum-args: (:), padding: 0pt) = { .. }

You can modify the parameters of the internal enum through enum-args.

If you have complex custom requirements for the table of contents, you can use:

#states.touying-final-sections(sections => ..)

As done in the dewdrop theme.
