xaringanExtra::use_remark_macros(x)

[dmi3kno]

May I suggest a xaringanExtra::use_remark_macros(x), which places a macros.js file into the slide directory with the functionality specified by character vector "x". Below are some suggested values and corresponding macros:

• "scale":
  Macro for scaling images, e.g. ![:scale 50%](/path/to/image), The discussion and code. Also discussed in the RMD bible
• "tweet"
  Macro for embedding tweets. Provided by Twitter, but may very well be wrapped for friendlier UI. Code and discussion
• "alert"
  Macro for standard alerts and messages.
• "columns"
  Excellent ideas by @emilyriederer for creating layout structure in macros
• "class" and "gen"
  Some ideas by Yongfu Liao in the Chocolate theme. He is able to make round corners and image shadow with it.
• "abs"
  For absolute placement of images. Again Yongfu Liao in his blogpost

There are some more ideas: sourcing JS scripts, calculating how long the current presentation should take, macro for adding macros (how meta!), random number generation

One thing to keep in mind: there should be clear separation between what can be done in tachyons and what spills here.

@dmi3kno : where can I find more information on how to use JS macros on a presentation? I am keen to try out a "typewriter carousel" but can't find a straightforward way to do so.
Cheers
