The {{str_find0 }} returns first appearance of a substring in a string, otherwise returns -1.Teamplaid:Str sub find which does the routine.
{{Str find0 |<string1>|<string2>}}
It is zero-based. So no need for extra {{#expr:{{Str find|}}-1}} calculations to use it in other templates. Handles strings up to 90 characters. Very fast on short strings. Uses enhanced algorithm to run the subroutine only when needed. {{Str find0|abcdef|abc}} → 0
{{Str find0|abcdef|def}} → 3
{{Str find0|abcdef|ghi}} → -1
{{Str find0|abcdef|abcdefghi}} → -1
{{Str find0|abcdef|efg}} → -1
