This template uses Lua :
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
