ढाँचा:Str find0

-1

Template documentation[view] [edit] [history] [purge]

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

• Template:Strfind short - rapidly finds string in expansion depth 6 rather than 21
