Evaluate code and syntax highlight the results

This function runs code and captures the output using evaluate::evaluate(). It syntax highlights code with highlight(), and combines all results into a single HTML div.

evaluate_and_highlight(
  code,
  fig_save,
  classes = downlit::classes_pandoc(),
  env = NULL,
  output_handler = evaluate::new_output_handler()
)

Arguments

code	Code to evaluate (as a string).
fig_save	A function with arguments plot and id that is responsible for saving plot to a file (using id to disambiguate multiple plots in the same chunk). It should return a list with components path, width, and height.
classes	A mapping between token names and CSS class names. Bundled classes_pandoc() and classes_chroma() provide mappings that (roughly) match Pandoc and chroma (used by hugo) classes so you can use existing themes.
env	Environment in which to evaluate code; if not supplied, defaults to a child of the global environment.
output_handler	Custom output handler for evaluate::evaluate.

Value

An string containing HTML.
