![](https://upload.wikimedia.org/wikipedia/commons/thumb/c/cf/Lua-Logo.svg/30px-Lua-Logo.svg.png) | 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
