قالب:In string/doc

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, 0 is returned.
Set |nomatch=anytext to replace that 0. 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
