Module:String (sandbox)

This string handling template returns the number of times that a pattern or search-string occurs in a source string. Counts non-overlapping matches only.

Usage

{{Str count|source string|pattern|plain_flag}}

If there is no occurrence of the source string in the pattern, this template returns 0.

Parameters

There are three parameters; the first two are required:

|source=–the source string. Required; alias: |1=.
|pattern=–the search-string or pattern to look for in the source string. Required; alias: |2=.
|plain=–a boolean flag indicating that pattern should be understood as plain text and not as a Scribunto ustring pattern (a unicode-friendly Lua-style regular expression). Optional; default: true.

Examples

{{str count |aabbacccaddaeeeeaffff|a}} → 5
{{str count |0123456789ABCDEF|X}} → 0
{{str count |Wikipedia:Manual of Style/Words to watch|:}} → 1
{{str count |Wikipedia:Manual of Style/Words to watch|a}} → 4
{{str count |abababa|aba}} → 2 // counts non-overlapping occurrences (matches must be disjoint)

Analysis and searching
{{str startswith }} {{str endswith }} Check if a string starts or ends with a given string. {{str find }}, {{strfind short }} Returns the numerical location of a given string in a string. {{str count }} Count the number of occurrences of a pattern within a string. {{string count in page }} Count the number of occurrences of a string within a given page's wikitext.		{{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.
