Template:In string .
0
This template is used on approximately 107,000 pages . To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage . The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.
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
