Touying 0.2.0 is done.

Implemented Features​

• Object-oriented programming: Singleton s, binding methods utils.methods(s) and (self: obj, ..) => {..} methods.
• Page arguments management: Instead of using #set page(..), you should use self.page-args to retrieve or set page parameters, thereby avoiding unnecessary creation of new pages.
• #pause for sequence content: You can use #pause at the outermost level of a slide, including inline and list.
• #pause for layout functions: You can use the composer parameter to add yourself layout function like utils.side-by-side, and simply use multiple pos parameters like #slide[..][..].
• #meanwhile for synchronous display: Provide a #meanwhile for resetting subslides counter.
• #pause and #meanwhile for math equation: Provide a #touying-equation("x + y pause + z") for math equation animations.
• Slides: Create simple slides using standard headings.
• Callback-style uncover, only and alternatives: Based on the concise syntax provided by Polylux, allow precise control of the timing for displaying content.
  • You should manually control the number of subslides using the repeat parameter.
• Transparent cover: Enable transparent cover using oop syntax like #let s = (s.methods.enable-transparent-cover)(self: s).
• Handout mode: enable handout mode by #let s = (s.methods.enable-handout-mode)(self: s).
• Fit-to-width and fit-to-height: Fit-to-width for title in header and fit-to-height for image.
  • utils.fit-to-width(grow: true, shrink: true, width, body)
  • utils.fit-to-height(width: none, prescale-width: none, grow: true, shrink: true, height, body)
• Slides counter: states.slide-counter.display() + " / " + states.last-slide-number and states.touying-progress(ratio => ..).
• Appendix: Freeze the last-slide-number to prevent the slide number from increasing further.
• Sections: Touying's built-in section support can be used to display the current section title and show progress.
  • section and subsection parameter in #slide to register a new section or subsection.
  • states.current-section-title to get the current section.
  • states.touying-outline or s.methods.touying-outline to display a outline of sections.
  • states.touying-final-sections(sections => ..) for custom outline display.
  • states.touying-progress-with-sections((current-sections: .., final-sections: .., current-slide-number: .., last-slide-number: ..) => ..) for powerful progress display.
• Navigation bar: Navigation bar like here by states.touying-progress-with-sections(..), in dewdrop theme.
• Pdfpc: pdfpc support and export .pdfpc file without external tool by typst query command simply.
