Editing Module:String/doc (section)

== count ==
Counts the number of times a given pattern appears in the arguments that get passed on to this module. Counts disjoint matches only.

Usage:
: <code><nowiki>{{#invoke:</nowiki>String|count|''source_str''|''pattern_string''|''plain_flag''}}</code>

OR

: <code><nowiki>{{#invoke:</nowiki>String|count|source= ''source_string'' |pattern= ''pattern_string''|plain= ''plain_flag'' }}</code>
Parameters:
; source_string
: The string to count occurrences in
; pattern
: The string or pattern to count occurrences of within source
; plain
: Boolean flag indicating that pattern should be understood as plain text and not as a [[mw:Extension:Scribunto/Lua reference manual#Ustring patterns|Scribunto ustring pattern]] (a unicode-friendly [[w:Lua (programming language)|Lua]]-style [[w:regular expression|regular expression]]); defaults to true

Examples:
* Count of 'a': <code><nowiki>"{{#invoke:String|count|aabbcc|a}}"</nowiki></code> → "{{#invoke:String|count|aabbcc|a}}"
* Count occurrences of 'aba': <code><nowiki>"{{#invoke:String|count|ababababab|aba}}"</nowiki></code> → "{{#invoke:String|count|ababababab|aba}}"
* Count of "either 'a' or 'c' ":<code><nowiki>"{{#invoke:String|count|aabbcc|[ac]|plain=false}}"</nowiki></code> → "{{#invoke:String|count|aabbcc|[ac]|plain=false}}"
* Count of "not 'a' ": <code><nowiki>"{{#invoke:String|count|aaabaaac|[^a]|plain=false}}"</nowiki></code> → "{{#invoke:String|count|aaabaaac|[^a]|plain=false}}"
* Count of "starts with 'a' ": <code><nowiki>"{{#invoke:String|count|aaabaaac|^a|plain=false}}"</nowiki></code> → "{{#invoke:String|count|aaabaaac|^a|plain=false}}"
