use crate::foundations::{elem, Content};
/// Emphasizes content by toggling italics.
///
/// - If the current [text style]($text.style) is `{"normal"}`, this turns it
/// into `{"italic"}`.
/// - If it is already `{"italic"}` or `{"oblique"}`, it turns it back to
/// `{"normal"}`.
///
/// # Example
/// ```example
/// This is _emphasized._ \
/// This is #emph[too.]
///
/// #show emph: it => {
/// text(blue, it.body)
/// }
///
/// This is _emphasized_ differently.
/// ```
///
/// # Syntax
/// This function also has dedicated syntax: To emphasize content, simply
/// enclose it in underscores (`_`). Note that this only works at word
/// boundaries. To emphasize part of a word, you have to use the function.
#[elem(title = "Emphasis", keywords = ["italic"])]
pub struct EmphElem {
/// The content to emphasize.
#[required]
pub body: Content,
