`quarto_preview` does not open right windows in RStudio IDE.

[cderv]

I'm on quarto 1.4.4 and somehow I am still getting this error: (edit: similar to #167)

> options(browser=\(url) cat(paste0(url, "\n")))

@idavydov usually we expect some reproducible example to help understand encountered issue.

Please can you share more about your context ?

• Is report.qmd part of a project for example ?

Also as much details as possible is welcome so that the minimum interpretation from me is required. This helps quickly solve problem.

Thank you !

[idavydov]

thanks, @cderv for creating a new issue. here's the minimal reproducible example which I found so far.

_quarto.yml

project:
 type: default
 

format:
 html:
    toc: true
    toc-depth: 2
    number-sections: true

editor: visual

execute: 
  cache: false

report.qmd

format:
  html

## hello

to reproduce the issue one could run:

> quarto::quarto_preview("report.qmd")
pandoc 
  to: html
  output-file: report.html
  standalone: true
  section-divs: true
  html-math-method: mathjax

Stop the preview with quarto_preview_stop()

It opens correctly in IDE.

This is also with CRAN version 1.4.4 🤔

So I am a bit puzzled

[idavydov]

Hi @cderv , just to double check, there are both files (qmd and yml) in the directory you are running, correct?

I tried from two locations: locally on my mac and on linux via ssh. Same results.

Maybe it has something to do with the IDE? I got these results just by calling the R REPL.

I'll try this ! I was assuming work RStudio IDE.

[cderv]

I still can't reproduce. I opened my Terminal, ran R to get the R console and then

> packageVersion("quarto")
[1] '1.4.4'
> quarto::quarto_preview("report.qmd")
pandoc
  to: html
  output-file: report.html
  standalone: true
  section-divs: true

  title: Report

Output created: report.html

Watching files for changes
Browse at http://localhost:4665/report.html

And it opens the browser in the correct window

Same in R Gui

[idavydov]

just so this doesn't get lost: the bug only reproduces when there's report.qmd as well as _quarto.yml in the directory. with report.qmd alone it works fine.

I just managed to reproduce this in a docker image. I created the two files in ~/x/, installed quarto from CRAN and ran:

> options(browser=function(url) cat(paste0("\nurl: ", url, "\n")))
> quarto::quarto_preview("report.qmd")
pandoc

[cderv]

Oh thanks for the docker image ! This will definitely help understand what is happening. I am really puzzled by this !

[cderv]

@idavydov I thought you shared a docker image, but it is just a link to rocker project.

Can you share Dockerfiles, or the steps to reproduce ?

Which image ? What files did you create ? etc...

Thank you !

[idavydov]

Hi @cderv ,
