// CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE.

// Usage
// -----
// The module exports one entry point, the `renderjson()` function. It takes in
// the JSON you want to render as a single argument and returns an HTML
// element.
//
// Options
// -------
// renderjson.set_icons("+", "-")
//   This Allows you to override the disclosure icons.
//
// renderjson.set_show_to_level(level)
//   Pass the number of levels to expand when rendering. The default is 0, which
//   starts with everything collapsed. As a special case, if level is the string
//   "all" then it will start with everything expanded.
//
// renderjson.set_max_string_length(length)
//   Strings will be truncated and made expandable if they are longer than
//   `length`. As a special case, if `length` is the string "none" then
//   there will be no truncation. The default is "none".
//
// renderjson.set_sort_objects(sort_bool)
//   Sort objects by key (default: false)
//
// Theming
// -------
// The HTML output uses a number of classes so that you can theme it the way
// you'd like:
//     .disclosure    ("⊕", "⊖")
//     .syntax        (",", ":", "{", "}", "[", "]")
//     .string        (includes quotes)
