Purpose

This template slightly simplifies the common task of decrementing a variable. It also returns the variable post-decrement. An undefined variable is decremented to -1.

Usage

{{--| name }}

  • name — The name of the variable (without #var syntax).

To return the variable pre-decrement, use: {{--| name | pre }}

To not return the variable, use: {{--| name | no }}
