alternatives-fn

alternatives-fn(start: 1, end: none, count: none, position: bottom + left, stretch: false, ..kwargs, fn)(source)

You can have very fine-grained control over the content depending on the current subslide by using #alternatives-fn. It accepts a function (hence the name) that maps the current subslide index to some content.

Example: #alternatives-fn(start: 2, count: 7, subslide => { numbering("(i)", subslide) })

Parameters

start : int    default: 1

The starting subslide number. Default is 1.

end : none | int    default: none

The ending subslide number. Default is none.

count : none | int    default: none

The number of subslides. Default is none.

position : alignment    default: bottom + left

The alignment of alternatives within the reserved space. Default is bottom + left.

stretch : bool    default: false

Whether to stretch all alternatives to the maximum width and height. Default is false. Important: If you use a zero-length content like a context expression, you should set stretch: false.

Returns: content
