{{#invoke:String|str_find|source=|}}

[bewerken] [purge] Template documentation

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; {{#invoke:String|str_find|source=Abcdefghijklm|A}}
  • a; {{#invoke:String|str_find|source=Abcdefghijklm|a}}
  • def; {{#invoke:String|str_find|source=Abcdefghijklm|def}}
  • klm; {{#invoke:String|str_find|source=Abcdefghijklm|klm}}
  • zyx; {{#invoke:String|str_find|source=Abcdefghijklm|zyx}}
  • empty;klm;{{#invoke:String|str_find|source=|klm}}
  • empty;empty; {{#invoke:String|str_find|source=|}}


  • 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.
