این الگو از لوآ استفاده میکند:
This is the { { str number } } meta-template.
It takes a string as parameter, and returns the number of leading digits. It does not handle اعداد منفی s or decimals, and stops at any minus sign '-' or dot '.' symbols.
If the parameter is empty or undefined, zero is returned:
{{Str number}} returns 0
{{Str number|}} returns 0
{{Str number| }} returns 0
The count is interrupted by anything but the ten digits:
{{Str number|abcde}} returns 0
{{Str number|123456}} returns 6
{{Str number| 123456}} returns 6
{{Str number|123 456}} returns 3
{{Str number|1234abc}} returns 4
{{Str number|1234abc56}} returns 4
{{Str number|15<ref>a reference</ref>}} returns 2
{{Str number|15(15)}} returns 2
{{Str number|-1234xx}} returns 0
{{Str number|12.34xx}} returns 2
