This template wraps the function {{#invoke:String|find|...}}, and provides the extra option to return an alternative string (including a blank string) when nothing is found.
Usage
{{In string|source_string|target_string|start_index|plain_flag|nomatch_returntext}}- or
{{In string|source=source_string |target=target_string |start=start_index |plain=plain_flag |nomatch=nomatch_returntext}}
{{In string
|source=
|target=
|start=
|plain=
|nomatch=
}}
- By default, when the target is not found,
0is returned. - Set
|nomatch=anytextto replace that0. Also,|nomatch=<blank> returns blank not 0.
- Note: outer spaces are not conserved.
- Using the nomatch option
- {{#if:{{in string|source=pancake|target=pizza|plain=true|nomatch=}}|Is a pizza|Not a pizza}} → Not a pizza
- {{#if:{{in string|source=Hawaiian pizza|target=pizza|plain=true|nomatch=}}|Is a pizza|Not a pizza}} → Is a pizza
