label
A label for an element.
Inserting a label into content attaches it to the closest preceding element
that is not a space. The preceding element must be in the same scope as the
label, which means that Hello #[<label>], for instance, wouldn't work.
A labelled element can be referenced, queried for, and styled through its label.
Once constructed, you can get the name of a label using
str.
Example
#show <a>: set text(blue)
#show label("b"): set text(red)
= Heading <a>
*Strong* #label("b")
Syntax
This function also has dedicated syntax: You can create a label by enclosing
its name in angle brackets. This works both in markup and code. A label's
name can contain letters, numbers, _, -, :, and ..
Note that there is a syntactical difference when using the dedicated syntax
for this function. In the code below, the <a> terminates the heading and
thus attaches to the heading itself, whereas the #label("b") is part of
the heading and thus attaches to the heading's text.
// Equivalent to `#heading[Introduction] <a>`.
= Introduction <a>
// Equivalent to `#heading[Conclusion #label("b")]`.
= Conclusion #label("b")
Currently, labels can only be attached to elements in markup mode, not in code mode. This might change in the future.
