slice

• Module: mod_base

Perform array-slice operations on a list.

Given a list = [1,2,3,4,5,6,7,8,9,0]

Get all elements from element M to element N:

{{ list|slice:[3,7] }} -> [3,4,5,6,7]
{{ list|slice:[3,-3] }} -> [3,4,5,6,7]
{{ list|slice:[-7,-3] }} -> [3,4,5,6,7]
{{ list|slice:[-7,7] }} -> [3,4,5,6,7]

Get all elements except the first N:

{{ list|slice:[3,] }} -> [3,4,5,6,7,8,9,0]
{{ list|slice:[-7,] }} -> [3,4,5,6,7,8,9,0]

Get all elements up to element N:

{{ list|slice:[,3] }} -> [1,2,3]
{{ list|slice:[3] }} -> [1,2,3]

Get all elements except the last N:

{{ list|slice:[,-3] }} -> [1,2,3,4,5,6,7]
{{ list|slice:[-3] }} -> [1,2,3,4,5,6,7]

{{ list|slice:[M,N] }}, where N < M will return []
{{ list|slice:[,] }}, where N < M will return [1,2,3,4,5,6,7,8,9,0]
