Building quarto book shows non-interactive progress bar

[hadley]

i.e.

processing file: names.Rmd
1/31                   
2/31 [unnamed-chunk-1] 
3/31                   
4/31 [unnamed-chunk-2] 
5/31                   
6/31 [unnamed-chunk-3] 
7/31                   
8/31 [unnamed-chunk-4] 
9/31                   

Previously it was (correctly) using the dynamic progress bar. I'm using knitr 1.43.

Same problem when knitting a single quarto doc when the output appears in the background jobs tab, rather than the build pane.

Previously it was (correctly) using the dynamic progress bar.

The new behavior cames from discussion in #2221 and commit 47bce01. It was introduced in 1.43

Current detection for simple mode is

knitr/R/utils.R

Lines 1136 to 1149 in ec4c9b6

	# test if it is a "terminal" connection (whether \r is supported)
	simple = (function() {
	# a global option to decide whether to use the simple progress output
	if (!is.null(res <- getOption('knitr.progress.simple'))) return(res)
	if (identical(con, '')) con = stdout()
	if (!inherits(con, 'connection')) return(TRUE)
	if (isatty(con)) return(FALSE)
	# when RStudio is available, return FALSE
	is.null(tryCatch(rstudioapi::versionInfo(), error = function(e) NULL))
	})()
	# use simple progress output without the bar but only progress and labels
	if (simple) return(list(
	update = function(i) cat_line(i, '/', total, s[i], '\n')
	))

When quarto is running R it will do it executing R in background session started with Deno as Rscript <file>. None of the specific checks return FALSE to no activate simple mode , and knitr will then detect that it is not running in RStudio IDE so activate the simple version (is.null(tryCatch(rstudioapi::versionInfo(), error = function(e) NULL)) returns TRUE

So probably the current detection does not work for the case of knitr run within Quarto. We need to find what works for this case....

I think even cli::is_dynamic_tty() is returning FALSE in the context of the R code executed by Quarto directly.

We need to find what works for this case....

I'm using an env var to detect the background jobs pane. This should work now.

[cderv]

This should work now.

This is now working in Background Job pane inside RStudio.

rather than the build pane.

@hadley I understand there could be a scenario where the Build pane is used ?

Also, I don't know if you were referring only to RStudio IDE panes, but just for referement, in terminal, it will still use the non-interactive progress bar. In same terminal session, we'll have

• Rscript -e 'rmarkdown::render("index.qmd") showing us the full progress bar
  • This means the knitr detection sees that non-simple progress bar can be used
• quarto render index.qmd showing us the simple progress bar
  • This means the knitr detection decide that simple progress bar should be used. Probably because background R process as I mentioned previously.

Just mentioning this for reference. The simple progress bar seems ok to have in Terminal for Quarto.

[hadley]

Yeah, I see quarto book usually in the build pane.

[cderv]

Thanks I tried Quarto Website and the Build Pane button triggers a render in the Job Pane.

So it seems only the Build button for a Quarto Book triggers rendering in the Build pane directly.

[cderv]

It should be ok in build pane now too. thanks

[hadley]

Thanks @cderv!
