Recently tried to start using Quarto in RStudio with my Windows 11 Surface Pro, and ran into what I now understand to be a known issue with Quarto not being able to render with an ARM system. I heard that Positron was working with these systems, so I tried to download the Windows 11 arm64 installer but keep getting the same error message:

"This program does not support the version of Windows your computer is running."

I've rechecked the system details multiple time. Windows 11 Home, 64-bit ARM processor, Snapdragon(R) X 12-core X1E80100. Is anyone aware of a workaround for this? I tried the "edit the installer to .exe at the end" fix posted on github with no change.

If you just want to open a raw .qmd or .md file on your phone, iOS shows plain text. I made a small viewer that renders the Markdown so you can read the prose, code, and math on mobile.

Md Preview:

• Renders Markdown incl. .qmd and .rmd (plus .md / .markdown / .mdx)

• Code blocks with syntax highlighting

• LaTeX math rendering and Mermaid diagrams

• Opens from Files / Share Sheet; on-device, nothing uploaded

On the App Store: https://apps.apple.com/app/id6760341080

Info: https://markdown.cybergame.ai/

To be clear it doesn't render/execute Quarto — it just renders the Markdown source of a .qmd so you can read it on a phone. Useful, or do you only ever read the rendered HTML/PDF?

I've been using quarto for a while, and have started having a strange problem that I can't figure out how to fix. For some reason, links - in preview only - keep redirecting me back to whatever page I'm on. If I use the static files in _site it works fine, and it works fine on my deployed site. However, here are the log messages in preview:

Browse at http://localhost:6256/
Listening on http://127.0.0.1:6256/
Opening in existing browser session.
GET: /
GET: /about.html
GET: /
GET: /resources.html
GET: /
GET: /
GET: /resources.html
GET: /

I clicked on my "about" link, and it shows that but then immediately does a second "GET" for the home page and that's all I see in the browser. It does this when I click on links in the header, but I can type out the URL (manually enter the "about.html") and it works fine. If I click on links further down the page, not in the header, it works fine. If I manually enter about.html to go to the about page, and then click on the "resources" link in the header, it redirects me back to the about page (or whatever page I'm currently on).

I can temporarily fix this: If I delete all of _site and then start preview, it's fine. But if I shut that down and restart again, without deleting _site, things are back to not working.

I've tried removing all extensions, removing .quarto, ... nothing seems to help. Any ideas?

Hello, I don't what doesn't work. I want to continue my script after I was using panel-tabset but when I add audio or links (figure2) in this panel-tabset, the text doesnt want to go out the panels (figure3).

Do you know the solution to get the rest of the script outside the panels after i using audio function or linking function in this panel ?

I built a small Lua filter that bridges GitHub alert syntax (> [!NOTE], > [!WARNING], etc.) to native Quarto callouts.

GitHub alert syntax doesn't seem to work in Quarto out of the box. The native solution uses a different syntax (::: {.callout-note}), which breaks portability with GitHub and other platforms.

The filter normalizes the syntax at the AST level before Quarto's callout processor runs (at: pre-ast stage), so you keep writing > [!NOTE] and Quarto renders native styled callout boxes automatically.

Features:

• Auto-detects Quarto — no configuration needed
• Custom alert types — any uppercase word, not just the five GitHub types
• No silent failures — unrecognised markers pass through as plain blockquotes

Install:

quarto add plbarrio/alerts-normalize

Declare in _quarto.yml:

yaml

filters:
  - at: pre-ast
    path: plbarrio/alerts-normalize

Bonjour, j'ai codé un petite page html pour un projet et je veux également le render en tant que pdf, cependant dans mon code se trouve une section dans laquelle des nombres aléatoires apparaissent. Lorsque je clique sur Render j'ai donc ma page html et à l'interieur de cette page apparait une icone pour télécharger en pdf, parfait me diriez vous, cependant lorsque je clique sur le téléchargement, un nouveau tirage de nombre aléatoires apparaissent, les numéros apparaissant dans le pdf ne sont donc pas les même que dans la page html, si vous pouvez m'aidez ça serait top.

De plus lorsque je télécharge le pdf, le texte occupe seulement la moitié de la page (voir image) et le code dépasse du bloc, savez vous comment résoudre cela ?

Je suis un débutant sur quarto, en espérant que vous pourrez m'aider

I've developed an LSP, autoformatter, and linter for Quarto, which also supports RMarkdown as well as standard Pandoc Markdown. It's a work-in-progress but maturing steadily. The autoformatter is becoming more and more stable, whereas the LSP and especially linter are in nascent stages.

A primary feature is its ability to run external formatters and linters (like air, ruff, black, etc) for code chunks in the Quarto/Pandoc/RMarkdown documents, which enables full formatting of entire documents.

Please check it out at https://github.com/jolars/panache and let me know what you think!

I am searching for a book template that renders the chapters with authors and affiliations for each chapter and then stitches everything together as a single book. Any ideas where I can find that or something similar?

My base template does not render the authors (pnly for the front page of the whole book) and I can't use indepdendent chapters as i heavily reley on cross-references between the chapters.

I'm having an issue when generating a PDF with the elsevier-pdf format in Quarto. Parts of my document are missing.

I double-checked the .qmd in VSCode, and all the content is there. Running quarto pandoc outputs everything correctly, so the problem only happens during PDF rendering. I even compared two screenshots — one from my VSCode showing the correct source and one from the generated PDF missing those parts.

Has anyone else experienced this issue or found a fix for this Elsevier template bug?

I would like to work on my iPad sometimes, but the .qmd extension frustrates many iOS Markdown editors. Does anyone know of one that will allow opening and saving in .qmd? And that will support LaTeX math and HTML figure blocks?

thanks

Shortly, if you are writing several code chunks that output a figure with some markdown text in between chunks, and it happens that the text appears at the top of all figures and then all figures in a row, here is the issue:

```{python}
#| label: This is the issue - DELETE THIS - Quarto will default the name
#| fig-cap: "Average Forces..."

I am currently writing a book with many chapters and want to create some summary stats on the chapters (think of a chapter with keyword counts and an illustration of the cross-references).

How can I do this using Quarto? Can I add some hidden meta-data to the chapters that can be collected and used in one of the chapters. Automatically identifying the cross-references would be nice, but I can also do this manually.

I am fluent in R. So when I have the data from within each chapter, the rest is doable.

Does anyone has suggestions on how to approach this?

Via thehtml-math-method key (in the YAML of your .qmd file), you can specify the HTML rendering option for your LaTeX code, and that's important because it makes a big difference in the digital accessibility of the resultant HTML file.

Today I tested each of the six rendering options listed on Quarto's website, and I've determined the webtex option is the best option because it is the only option that neatly inserts the intact string of raw LaTeX code into the alt-text (and title) of the rendered HTML code's <img> element for each string of LaTeX code from your .qmd file, while also producing a beautiful rendered <img> element that looks just as good as that of any of the other rendering options. (As a bonus: anyone who has access to the HTML file can select and copy any rendered LaTeX image while viewing the rendered HTML file, and then paste that LaTeX image as plain text if they want to inspect the entire intact string of LaTeX code for that image.)

The other rendering options either don't include the intact string of LaTeX code into the HTML code at all, or they bury it deep within a mountain of nested and unfriendly HTML tags. I took some screenshots of the HTML output from my tests today, but I can't paste them here without hosting the images on some website and I'm too lazy to do that right now, though I'd be happy to do it if it would help. I tested this in Chrome and Microsoft Edge (identical results)—will test in Safari soon.

In summary, all you need to do is include this into your YAML:

format:
  html:
    html-math-method: webtex

Hi everyone,

I’m building a Quarto Book website with lecture contents, and I’d like to also include a RevealJS presentation of the same material.

Ideally, I’d like either:

• to embed the presentation directly in the website, or
• to provide a link from the book to the RevealJS slides.

Is it possible to integrate both content types in the same Quarto project?

If so, what’s the recommended approach (e.g., same _quarto.yml, separate output folders, iframe embedding, etc.)?

Any suggestions, examples, or best practices would be very welcome!

Thanks in advance.

Hi guys it will be great if you could help me solve the issue iam facing when rendering quarto file. It says: Problem with running R found at C:\PROGRA~1\R\R-45~1.1\bin\Rscript.exe to check environment configurations. Please check your installation of R. When I tried installing quarto. It is ging the error: ERROR: lazy loading failed for package 'quarto' * removing 'C:/Users/xxxx/AppData/Local/R/win-library/4.5/quarto' * restoring previous 'C:/Users/xxx/AppData/Local/R/win-library/4.5/quarto' Warning in install.packages : installation of package ‘quarto’ had non-zero exit status

The downloaded source packages are in ‘C:\Users\xxx\AppData\Local\Temp\Rtmp65CGLZ\downloaded_packages’ I tried reinstalling r, rstudio and quarto file. It would be great if anyone cab help me in this.

I’m very new at Quarto and am exploring it as an alternative to Beamer/LaTeX for creating slides for a university engineering course. The ADA requirements for accessibility are kicking in next April and all university digital content must be 100% accessible. Since LaTeX is difficult if not impossible to generate compliant PDFs, I’m looking for an alternative. Quarto has been really nice so far but I don’t want to spend too much time in it if it can’t easily make my slides accessible.

Does anyone here know if Quarto can do this easily? Any examples or tutorials that you know about for accessibility?

However, I have some appendices that are no longer in paragraph form. They're lists of instructions, images/tables, and other forms where the indentation and line spacing spacing are causing it to look really strange. What's my best way to alter those settings for each appendix files .qmd? My goal is to remove the leading indentation on a new line and to go down to 1.0 spacing for selected appendices. Thanks for any guidance.

Hi all,

I am trying to write up a book for a class I am teaching in the fall. I have a Table of Contents of the left side that shows up in full when I am at the main page. However, when I visit some of the pages in the book, the Table of Contents no longer shows all of the content.

I am uploading the images so you can see what I am talking about. Is there something I am missing in the _quarto.yml file?

Thanks.

I'm working with Python in .qmd files in VSCode. While it autocompletes code, what would be really great is if I could autocomplete variable names when working with data frames (the way that RStudio autocompletes variable names in R, which is really quick and intuitive). I have noticed that variable name autocomplete works in the Python shell, which also has a number of nifty features, e.g. dataframe inspector. But the autocomplete for variable names does not work in the .qmd document itself. Is there a way to get this to work? (P.S. I tried switching to RStudio, but this also failed to autocomplete variable names when working with Python)

Hello, could anybody please help... I am trying to use quarto in R so I can easily share graphs that are often being updated with the rest of my team on rpubs. It was all going okay until I deleted a .qmd file that I didn't need. This .qmd file was the first one I created when I set up my quarto project, but because it had brackets in the file name it couldn't be used, so I created a new .qmd that I was using with no issues. A few weeks later I deleted the old, unusable .qmd file and then when rendering my project started getting the error message below. I then restored the deleted .qmd file but I am still getting the error message. I have been looking up how to fix it on github etc, but none of the solutions seem to be working. I was considering just starting a new quarto project and copying over the text, but quarto doesn't really seem to allow for easy copy and pasting so this would be a tedious process. Does anyone have any suggestions? Thanks in advance!!

I registered for this course and am finding it very helpful. Figured I’d share with others who are looking to learn quarto. Please remove if not allowed.

I’ve been following Yan Holtz for years - this is his course.

I’m working on a large data analysis report in Quarto that I share with my supervisor. The document has become long and slow to render and open in a browser, so I’m considering splitting it up.

My current idea is to turn it into a Quarto Book, where each section of the report becomes its own .qmd file (e.g., import.qmd, qc.qmd, clustering.qmd, etc.), and render them all together into a single HTML file using self-contained: true.

I like that this should keep the output to just one file and should let me preview and edit chapters independently during development.

Has anyone else used this kind of setup? Does it scale well for long or complex analyses (with plots, tables, etc.)? Are there any caveats I should be aware of?

Would appreciate any thoughts or alternative suggestions!

Looking to hire a freelancer for a quick task - please message me if you have experience creating customised html output.

I'd like to include certain sections or even chapters in HTML output format, but not in PDF format. Is there a way to do this?

Mostly these are notes that I'd like to have when reading the HTML but would unjustifiably complicate the formatting and page count of the PDF.

There is an issue here which seems to indicate that this is not possible: https://github.com/quarto-dev/quarto-cli/issues/9630

But is there a hack that can work? Like add some conditionality to the `_quarto.yml` file to pick up a qmd file for one format but not the other.
