This template implements the :Module:String|find function ({{#invoke:String|find|...}}).
It has an extra option to return any text or <blank;> when not found.
Usage
[编辑]{{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 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
