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