List Repeater

Functionality

Allows explicit repeat of lists and elements. The node is data type agnostic, meaning it makes no assumptions about the data you feed it. It should accepts any type of data native to Sverchok..

Inputs

Input	Description
Data	The data - can be anything
Number	The amount of times to repeat elements selected by the Level parameter

Parameters

Level and unwrap.

Level

It is essentially how many chained element look-ups you do on a list. If SomeList has a considerable nestedness then you might access the most atomic element of the list doing SomeList[0][0][0][0]. Levels in this case would be 4.

unwrap

Removes any extra layers of wrapping (brackets or parentheses) found at the current Level. If the element pointed at is [[0,2,3,2]] it will become [0,2,3,2].

Outputs

• Lists (nested). The type of Data out will be appropriate for the operations defined by the parameters of the Node.

Examples

Trying various inputs, adjusting the parameters, and piping the output to a Debug Print (or stethoscope) node will be the fastest way to acquaint yourself with the inner workings of the List Repeater Node.

A practical reason to use the node is when you need a series of copies of edge or polygon lists. Usually in conjunction with Matrix Apply, which outputs a series of vertex lists as a result of transform parameters.
