HRWiki:Counter

Usage

0	Increments the counter id by increment and displays the result; increment can be omitted, and defaults to 1.
{{#resetcount:id|value|increment}}	Silently sets the counter id to value minus increment (so that the next count by increment will display value); value and increment can be omitted, and both default to 1.
{{hcount}} {{vcount}}	Used in sortable tables. See [#Sortable_Tables below].

Examples

count is a parser function that returns an integer that increments each time the function is called:

Code	Gives
0	1
0	2
0	3
0	4
0	5

The counters can be given different names, so you can have more than one of them on the same page:
(The actual name doesn't matter, so long as they're different. If you use a counter in a template, pick a name that'll be unique.)

Code	Gives
0	1
0	1
0	2
0	3
0	2
0	4

You can also make the counter count by twos, or by any other number:

Code	Gives
0	2
0	4
0	6
0	8
0	10

Different increments can be used at different times, depending on what is needed:

Code	Gives
0	1
0	2
0	5
0	5
0	4
0	6

The counter can be reset partway through a page:

Code	Gives
0	1
0	2
0	3
{{#resetcount:basic}}
0	1
0	2
0	3

You can also set what number you want to start on:

Code	Gives
{{#resetcount:starting|11}}
0	11
0	12
0	13
0	14
0	15

If you're using an increment, you need to give it to #resetcount too:

Code	Gives
{{#resetcount:starting evens|14|2}}
1	14
1	16
1	18
1	20
1	22

Use a negative increment to count down. As noted above, be sure to pass the increment to #resetcount too:

Code	Gives
{{#resetcount:countdown|3|-1}}
0	3
0	2
0	1
0	0
0	-1

You can use the counter in other parser functions:

Code	Gives
	odd
	even
	odd
	even
	odd

Code	Gives
0	1
0	4
0	9
0	16
0	25

Sortable Tables

When using count in sortable tables, please use the {{hcount}} and {{vcount}} templates. Be sure to carefully read their documentation in order to sort table entries correctly.
