I saw an intriguing tweet this afternoon.
🧙 ♂️Live preview for R Markdown!— Jozef Hajnala (@jozefhajnala) January 2, 2019
TIL that you can have a live preview of your #rstats Markdown docs!
Just use the infinite_moon_reader function from the xaringan package.
It works for all single-HTML-file outputs and even comes with a pre-made RStudio Addin!
When Charles was visiting for #RCurious in June, she had written her slides in
xarigan and was raving about infinite moon reader. I assumed it was something far too fancy for us Curious types. But this tweet has me interested.
Is this infinite moon reader thing magical or all hype? What does it mean by live preview? Maybe I don’t have to
blogdown::serve_site() in order to see updates on my post.
NOTE: here I am talking about blogging etc, not about xarigan slides (which is definitely on my 2019 to learn list)
Install the xarigan package and load it.
Open a rmd document that you are working on and in the console call
xarigan::inf_mr() i.e. infinite moon reader.
Write something and use Ctrl/Command-S to save it. Your document will update automatically in the Viewer pane.
blogdown::serve_site() do that anyway?
Yes, when you are working in blogdown and save, it runs
blogdown::serve_site() and updates the Viewer pane. But that is not true of all markdown instances. In
radix or when you are just doing an analysis in a markdown document, knitting the file can be slow.
xarigan::inf_mr() running in the console, you can have the same functionality of
blogdown::serve_site() on all markdown documents. And you can use it in blogdown too, so you don’t need different knitting tricks for different situations.
inf_mr() is occupying your console, it is out of action for other things. But as Charles says, that might not be a bad thing, when you are actually trying to put words on the page.
