Usage

{{Str find|text|sub_string}} = Position of first appearance of sub_string in text.

Examples

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

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


  • Case sensitive.
  • Returns -1 if sub_string not found
  • Character position is 1 based (not 0 based as usual in calculations).
  • Warning: if sub_string is empty, then this routine will return 1 !!! This case will often have to be handled specially.
