version

A version with an arbitrary number of components.

The first three components have names that can be used as fields: major, minor, patch. All following components do not have names.

The list of components is semantically extended by an infinite list of zeros. This means that, for example, 0.8 is the same as 0.8.0. As a special case, the empty version (that has no components at all) is the same as 0, 0.0, 0.0.0, and so on.

The current version of the Typst compiler is available as sys.version.

You can convert a version to an array of explicitly given components using the array constructor.

Constructor

If a type has a constructor, you can call it like a function to create a new value of the type.

Creates a new version.

It can have any number of components (even zero).

#version() \
#version(1) \
#version(1, 2, 3, 4) \
#version((1, 2, 3, 4)) \
#version((1, 2), 3)

components

int or array

Required Positional

Positional parameters are specified in order, without names.

Variadic

Variadic parameters can be specified multiple times.

The components of the version (array arguments are flattened)

Definitions

Functions and types and can have associated definitions. These are accessed by specifying the function or type, followed by a period, and then the definition's name.

at

Retrieves a component of a version.

The returned integer is always non-negative. Returns 0 if the version isn't specified to the necessary length.

index

int

Required Positional

Positional parameters are specified in order, without names.

The index at which to retrieve the component. If negative, indexes from the back of the explicitly given components.
