NAME

Template::Liquid::Tag::Increment - Document-level Persistant Number

Description

Creates a new number variable, and increases its value by one every time it is called. The initial value is 0.

Synopsis

    {% increment my_counter %}
    {% increment my_counter %}
    {% increment my_counter %}

...will result in...

    0
    1
    2

Notes

Variables created through the increment tag are independent from variables created through assign or capture.

In the example below, a variable named "var" is created through assign. The increment tag is then used several times on a variable with the same name. Note that the increment tag does not affect the value of "var" that was created through assign.

    {% assign var = 10 %}
    {% increment var %}
    {% increment var %}
    {% increment var %}
    {{ var }}

...would print...

    0
    1
    2
    10
