syntax highlighting in print.vertical()

[wlandau]

It would be nice to see syntax highlighting when I print out styled code in the console and in knitr / R Markdown reports:

styler::style_text("
function(x){
  x * (sqrt(5) + 1) / 2 
}
")
#> 
#> function(x) {
#>   x * (sqrt(5) + 1) / 2
#> }

Motivating use case: ropensci/drake#489. Packages that may help:

• fansi
• prettycode
• crayon
• highlight
• highr
• colorout

Thanks for raising the issue and putting all the references here, really appreciate that. In fact, this should be straightforward. See my branch highlight-print-vertical for a primer. Using prettycode::highlight() seems to be a good solution. Have not tested the others. The dependency would probably be added under Suggests.
