Template:Str sub find/doc

Template:Documentation subpage Template:Lua The Template:str_sub_find searches for a substring in a string at the given offset.

Usage

Template:Tlx

It returns 1, if string2 is found in string1 at the given offset, otherwise it will return empty string. This makes the result easy usable in Help:Extension:ParserFunctions like {{#if:|}}.
Offset is zero-based and can be omitted if zero.
