I'll be talking about Quarto at PyData in September.

Focus will be on how Quarto can be used to get your Notebooks Analysis to the world easily, and under different forms.

Don't hesitate to share anything you would like me to tackle, and if it relates I am happy to !

And maybe see you there !

Happy to announce ✨quarto-revealjs-editable✨

This fully supersedes the imagemover extension, as I back then didn't realize the potential. You can now also move, resize, change font size and alignment for text in your slides

Always happy to help !

A complex use case with Quarto - a good story for a blog post and probably for a talk at conferences.

Your journey with this is insightful - and will be for many.

Thanks for sharing back with us on Discussion board!

I’ve been working on an update to the #quarto R package for weeks. I hope it improves your #rstats workflow with Quarto.

Lots of new helpers and tooling beyond the usual CLI wrappers. I believe some functions will be really useful!

Looking forward to your feedback!

You've heard about brand.yml support in #Quarto, but you do not really know much about what this new brand theming stuff is? And why again a new theming system?

Then this is the opportunity for you to learn more by listening to @grrrck.xyz in this @rfortherestofus.com podcast!

Functional Programming Tools A complete and consistent functional programming toolkit for R.

Bleeding edge update for the #tidyverse purrr package with even more seamless #rstats parallel maps.

Introducing our shiniest new adverb: `in_parallel()`. Just wrap your function to take advantage of blazing fast parallel processing via mirai.

Pretty cool!
Did you need to manually fix the syntax for the .qmd document?
Or does Claude Code already know well how to write Quarto Presentation slides?

Cette semaine, j'ai eu l'occasion de présenter une nouvelle fonctionnalité de #quarto lors des Rencontres R à Mons, en Belgique :

Update for #quarto users producing PDF with LaTeX

Since Quarto 1.8.10, the default PDF engine is now LuaLaTeX instead of XeLaTeX.

This follows the recommendation in LaTeX NEWS issue 40, Nov. 2024, from the “LATEX Tagged PDF” project.

Please, try it out. We don't expect much impact, though.

Nice trick ! Can you open an issue in the repo so that we can add this rule and fix in quarto ?
You can ping me there.

This would need to be using SCSS with the right variable for the block header background.

Hey #Quarto users !

Next v1.7 release is coming soon !

Part of the updates are about Pandoc 3.6.3 bundling with updated LaTeX templates.

Latest pre-release 1.7.19 have this change: github.com/quarto-dev/q...

If you are a #quarto extension developer, please try this out!

Docs update soon.

Changelog

I want to highlight that v0.1.1 of {ellmer} has been on CRAN for a few weeks now. This version includes a ton of improvements when using an LLM hosted on Azure, AWS, Databricks, or Snowflake from #rstats -- which is pretty common in enterprise settings. 🧵

- Possibly shipping this with another type of extension.
We don't have yet a Brand Extension type but we are thinking about it. This would be the right way to distribute this, as with other extensions like filters or shortcode.

There is no built in way for this. I mean `_brand.yml` needs to be locally present. Though several tools can help
- pre-render script for a project making sure local version is sync with an online one.
- extension for project template that would ship the file as starter pack for any new project

So if your extension is just styling you may be able to use _brand.yml file only and "distribute" this file. Though depending on what you customize a theme through .scss is interesting.
Using a Format extension for Reveals allows to customize configuration of the default format and ship resources.

It depends what you do exactly in your extension. `_brand.yml` file is a way to set some styling using YAML schema that will be understood by some quarto format, and also some other tools (like for now shiny for python).
On quarto only view, it is similar to a single theme file with SCSS syntax.
