Get rules

Set rules are not only useful to set default parameters. They are also useful for configuration more broadly. This is particularly useful for templates, which can use elements for fine-grained configuration.

Get rules (e.get) allow you to read the currently set values for each element's fields. Here's a basic example:

#import "@preview/elembic:1.1.0" as e

#show: e.set_(elem, count: 1, names: ("Robert",))
#show: e.set_(elem, count: 5, names: ("John", "Kate"))

// Output:
// "The chosen count is 5."
// "The chosen names are Robert, John, Kate."
#e.get(get => {
  [The chosen count is #get(elem).count.]
  [The chosen names are #get(elem).names.join[, ].]
})
