Usage

{{Str find|text|sub_string}}

Returns the position of first appearance of sub_string in text.

  • The comparison is case sensitive.
  • Returns -1 if sub_string not found
  • Character position is 1 based (not 0 based as usual in calculations).
  • If sub_string is empty, this routine returns 1. This case will often have to be handled specially.

Examples

In the examples, the string to be searched is Abcdefghijklm:

  • A; 1
  • a; -1
  • def; 4
  • klm; 11
  • zyx; -1
  • empty;klm;-1
