模板:Str count/doc

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)
