> **Kosti ( holiday mode🌴)** (@kgourg; 1/0): @xenophar Nothing that matches the interactivity sadly. Most alternatives try to match knitr or pweave, which aren't really interactive. https://t.co/G3CjhSc1gT  [&#8618;](https://twitter.com/kgourg/status/1559451553194512384)

> **Shah Nawaz** (@shah_f1; 1/0): @FilmicAesthetic for example we can print rmarkdown file to pdf by knitr. what if i write notes for myself in console while running .R  file ? how can I print those in pdf. It can help to tally the code. in this way we will have 2 files. 1 with comments from console and 1 with code  [&#8618;](https://twitter.com/shah_f1/status/1558549933568966659)

> **EHolmes** (@eeholm; 1/0): This shows how to dynamically create tables that have table numbers and table captions across all formats (well, there is a bug for flextable+Word, but Quarto knows about it). It uses the `knitr::knit_expand()` trick which allow dynamic vars as `{{https://t.co/iydNWsEPuj.match}}`  [&#8618;](https://twitter.com/eeholm/status/1557869017791991810)

> **Tom Mock ❤️ Quarto** (@thomas_mock; 1/0): @sharoz @charliejhadley @rstudio The traditional knitr syntax will always work, so no need to force a change.

> **Tom Mock ❤️ Quarto** (@thomas_mock; 1/0): @sharoz @charliejhadley @rstudio "prefer" here is indicating that the Quarto docs will only show that syntax. It's cross-language (R/Py/Julia) whereas {r echo=TRUE} is knitr only.

> **Ronny Bergmann @ GAMM** (@ronnybergmann_; 1/0): @MickaelCanouil @_tarleb @quarto_pub ...and don't get me wrong, whoever wants to use Jupyter or knitr should please do that. I feel I have more python versions installed than I ever used it – and no experience with R, so I would prefer to not spent (probably much) time setting that up.

> **Mickaël CANOUIL** (@MickaelCanouil; 1/0): @ronnybergmann_ @_tarleb @quarto_pub Of course, Jupyter is the best kernel when one wants to use Python, but for all (or almost) other cases knitr will work smoothly (it relies on the R package of the same name, thus on R itself as well).

> **Mickaël CANOUIL** (@MickaelCanouil; 1/0): @ronnybergmann_ @_tarleb @quarto_pub Depending on the main language, you have to set a kernel/engine which is going to be used for the whole document.
> Julia has a dedicated kernel.
> For Python, indeed there is Jupyter.
> For R, there is knitr.
