This template uses Lua :
This template will allow manipulation or retrieve properties of an array list using a delimiter. It handles four functions: count, get, pos and math.
{{Array|<Function>|<Array items>|<Delimiter>|<Property>|Parameters (optional)}}
5th parameter only valid with pos function when limiting multiple outputs to a single position.
Count Will count the total number of items in the array using the designated separator. Leading or trailing separators are not stripped.
{{Array |count|This is my array| }} → 4{{Array |count|An,array,separated,by,commas|,}} → 5{{Array |count|An,array,with,trailing,commas,|,}} → 6Get 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|A sentence of typical words| |5}} → words{{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:invalidPos 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}} → 4Math 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|,|min}} → 2{{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
String-handling templates
(help page)
Substring (select chunk of string by its position)
{{ str sub new }} Select a substring based on starting and ending index counted in either direction. {{ str left }} Keep the first N characters of a string, or duplicate it to N characters. {{ str crop }} Return all but the last N characters of a string. {{ str index }} Return the N-th character of a string.
{{ str right }} Return substring starting at N-th character to end of string. {{ str rightc }} Return the last N characters of a string; or a given value if empty. {{ str sub old }} Return substring of given length starting at N-th character.
Trimming (select/remove chunk of string by character type)
Select/remove specific item from string
{{ delink }} , {{ trim brackets }} Removes wikilink brackets (wikicode); all or outer only . {{ Plain text }} Removes wikicode (formatting and brackets) {{ PAGENAMEBASE }} Trim off any parenthesis text at the end of a string (disambiguation). {{ title disambig text }} Returns text in parentheses at the end of a string (disambiguation).
{{ title year }} Returns the 3-or-4-digit year from a pagename, if any. {{ title decade }} Returns the 4-digit decade from a pagename (e.g. "1740" from "Foo 1740s bar"), if any. {{ title number }} Returns any number from a pagename. {{ WikiProjectbasename }} Removes "WikiProject" from a pagename.
Insertion, replacement and length
{{ loop }} Repeat character string a specified number of times. {{ replace }} Returns the string, after replacing all occurrences of a specified string with another string. {{ str rep }} Returns the string, after replacing the first occurrence of a specified string with another string. {{ digits }} Returns the string, after removing all characters that are not digits 0–9 {{ Nowiki }} Displays wikitext as plain text.
{{ str len }} Returns a string's length. {{ str ≥ len }} Check if a string is "longer or equally long" or "shorter" than a given length. {{ str ≤ len }} Check if a string is "shorter or equally long" or "longer" than a given length. {{ str ≠ len }} Check if a string is "not equal" or "equal" to a given length.
Analysis and searching
{{ Array }} Array item manipulation and retrieval. {{ a or an }} Takes a noun and produces the appropriate indefinite article, based on whether the first letter is a vowel. {{ in string }} Returns optional string when given string is not found {{ Isnumeric }} Returns number when true, blank when not numeric. {{ str letter }} Returns the number of letters that begin a string. {{ str number }} Returns the number of numbers that begin a string.
