Template:Array Source: en.wikipedia.org/wiki/Template:Array
 | This template uses Lua: |
This template will allow manipulation or retrieve properties of an array list using a delimiter. It handles five functions: count, get, pos, math and sort.
Usage
[edit]{{Array|<Function>|<Array items>|<Delimiter>|<Property>|Parameters (optional)}}
5th parameter only valid with pos function when limiting multiple outputs to a single position.
Functions
[edit]- Count
Will count the total number of items in the array using the designated separator. Leading or trailing separators are stripped.
{{Array|count|This is my array| }}→ 4{{Array|count|An,array,separated,by,commas|,}}→ 5{{Array|count|An,array,with,trailing,commas,|,}}→ 5
- Get
Will get the Nth item in the array, numeric value only. Can use negative value to work backwards. Last or -1 will get end item. Invalid value returns error.
{{Array|get|My,wiki,test,array|,|3}}→ test{{Array|get|A.list.of.dot.separated.items|.|2}}→ list{{Array|get|The almost last item is nearly final| |-2}}→ nearly{{Array|get|The last item is final| |last}}→ final{{Array|get|Invalid input returns error| |foobar}}→ void:invalid
- Pos
Will retrieve the position in array of the search item. If duplicates are found, will output all positions delimited by comma. Output can be limited by specifying a 5th parameter.
{{Array|Pos|<Array items>|<Delimiter>|<Search Term>|<Nth occurrence> (optional)}}
{{Array|pos|A sentence of typical words| |sentence}}→ 2{{Array|pos|A.wiki.test.string.in.a.test.array|.|unmatched}}→ void:nomatch{{Array|pos|A.wiki.test.string.in.a.test.array|.|test}}→ 3,7{{Array|pos|Position,of,the,second,test,in,a,test,array|,|test|2}}→ 8{{Array|pos|2,4,6,6,7,11,12|,|7}}→ 5{{Array|pos|2,4,6,6,7,11,12|,|6|2}}→ 4
- Math
Will do calculations on the array items if all numeric. Options are sum (sum of all item numbers), min and max.
{{Array|math|2,4,6,6,7,12|,|sum}}→ 37{{Array|math|2,4,6,6,7,12|,|max}}→ 12{{Array|math|3.3.4.5.5.6|.|min}}→ 3{{Array|math|3.3.f.5.5.q|.|min}}→ void:isalpha
- Sort
Sort items in the array, default ascending/chronological, numeric first. Use parameter "a" to sort alpha first and/or "r" to reverse order
{{Array|sort|2,9,6,8,7,12|,}}→ 2,6,7,8,9,12{{Array|sort|2,9,6,8,7,12|,|r}}→ 12,9,8,7,6,2{{Array|sort|2,9,6,d,8,7,a,12|,}}→ 2,6,7,8,9,12,a,d{{Array|sort|2,9,6,d,8,7,a,12|,|a}}→ a,d,2,6,7,8,9,12{{Array|sort|3,9,6,d,8,7,a,12|,|ar}}→ 12,9,8,7,6,3,d,a (alpha starts first from the right if reversing the sort order){{Array|sort|is everything up mixed| }}→ everything is mixed up
