Template-info.png Dokumentation für die Vorlage {{Str find0}}[Ansicht] [Bearbeiten] [Versionsgeschichte] [Aktualisieren]

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
