Wrapper template for function posnq in Module:String2.
- posnq (position, no quotes) returns the numerical start position of the first occurrence of one piece of text ("target") inside another ("source"). UTC characters are supported.
- It returns nil by default if no match is found, or if either parameter is blank. If no match is found it can return the value of an optional "nomatch" parameter.
- It takes the text to be searched in as the first unnamed parameter (or
|source=), which is trimmed. - It takes the text to match as the second unnamed parameter (or
|target=), which is trimmed and any double quotes " are stripped out. That allows spaces at the beginning or end of the match string to be included in a consistent manner. - It can take an optional third unnamed parameter (or
|plain=), which is trimmed. If it's set to false, then the search accepts Lua pattern-matching for the target, otherwise a plain search is used. - It can take an optional fourth unnamed parameter (or
|nomatch=), which is trimmed. This value is returned if no match occurs. Setting|nomatch=0makes the output compatible with the find function in Module:String.
