“We have a plan, not a promise!”

Who am I?

• Current lead programmer of the Quarto project
• Recovering academic
• Joined Posit three years ago

What is Quarto?

A reboot of RMarkdown, built from the ground up to support both Knitr and Jupyter ecosystems equally well.

What can you do with Quarto?

demo - create a simple .qmd document with code, and render it to:

• a webpage
• a revealjs resentation
• a dashboard
• a PDF document

Then do the same from the .ipynb file.

Quarto, where we are

• Great tooling: we’ll autocomplete your YAML, and let you know if you make mistakes.

Quarto 1.4 {.30-70-dark}

• Inline Code Syntax
• Dashboards
• Shiny for Python
• Crossrefs
• Typst

Inline Code Syntax {.30-70-light}

• Quarto now offers a unified syntax for inline code in both Python and R

• The value of 1 + 2 is 3 (written {python} 1 + 2)

• Note this is slightly different from the usual inline r syntax.

• The legacy syntax remains supported in knitr.

• Very simple, but you’ll see this syntax everywhere.

Dashboards {.30-70-dark}

• source, demo

Shiny for Python

• source, demo

• These can be published to https://shinyapps.io just like Shiny for R documents

Shiny for Python

• source, demo

• These can be published to https://quarto.pub, GitHub Pages, or anywhere you host static web pages!

Crossrefs {.30-70-dark}

Anything goes

Contents of Figures and Tables and Listings can be anything you want: images, text, videos, interactive content, etc. (Demo)

Custom crossreference types

You can define Videos, Diagrams, Supplemental Tables, etc. (Demo)

Typst {.30-70-light}

• Typst is a new language for defining high-quality documents. Think “what if LaTeX but not from the 80’s”

• Just use format: typst (Demo)

Thanks!
