Template documentation[view] [edit] [history] [purge]

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[change source]

{{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
