Describes a kind of value.

\n

To style your document, you need to work with values of different kinds:\nLengths specifying the size of your elements, colors for your text and\nshapes, and more. Typst categorizes these into clearly defined types and\ntells you where it expects which type of value.

\n

Apart from basic types for numeric values and typical\ntypes known from programming\nlanguages, Typst provides a special type for content. A value\nof this type can hold anything that you can enter into your document: Text,\nelements like headings and shapes, and style information.

\n

Example

\n
#let x = 10\n#if type(x) == int [\n  #x is an integer!\n] else [\n  #x is another value...\n]\n\nAn image is of type\n#type(image("glacier.jpg")).\n
\"Preview\"
\n

The type of 10 is int. Now, what is the type of int or even type?

\n
#type(int) \\\n#type(type)\n
\"Preview\"
\n

Unlike other types like int, none and auto do not have a name\nrepresenting them. To test if a value is one of these, compare your value to\nthem directly, e.g:

\n
#let val = none\n#if val == none [\n  Yep, it's none.\n]\n
\"Preview\"
\n

Note that type will return content for all document elements. To\nprogrammatically determine which kind of content you are dealing with, see\ncontent.func.
