counter

{counter} is used to print out a count. {counter} will remember the count on each iteration. You can adjust the number, the interval and the direction of the count, as well as determine whether or not to print the value. You can run multiple counters concurrently by supplying a unique name for each one. If you do not supply a name, the name “default” will be used.

If you supply the assign attribute, the output of the {counter} function will be assigned to this template variable instead of being output to the template.

Attribute	Required	Default	Description
name	No	default	The name of the counter
start	No	1	The initial number to start counting from
skip	No	1	The interval to count by
direction	No	up	The direction to count (up/down)
print	No	true	Whether or not to print the value
assign	No	n/a	the template variable the output will be assigned to

{counter name='c1' start=100 skip=2 direction='down'}-
{counter name='c1'}-
{counter name='c1'}-
{counter name='c1' direction='up'}-

final number is: {counter name='c1'}

output:

100-
98-
96-
94-

final number is: 96
