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 <syntaxhighlight lang="text" class="" id="" style="" inline="1">Abcdefghijklm</syntaxhighlight>:
- 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.
