(Feeding the numbered parameters as numbers instead, to get white space stripping. Slightly more efficient, and simpler code. Tested in the /sandbox.) |

Template documentation 
|
This template uses (or will be using) Lua programming language.
Please see Wikipedia:Lua if you want to learn more about Lua or help convert other templates. |
This is the {{str len}} meta-template.
It takes a string as parameter and returns its length (excluding spaces at the start and end). It can now count as high as necessary.
Examples[edit]
If the parameter is empty or undefined it is considered to be of zero length:
{{str len}}returns 0{{str len|}}returns 0{{str len| }}returns 0
It counts the length correctly, even if the string contains spaces, looks like a number, or contains special characters:
{{str len| ab cde }}returns 6
{{str len| 1234567 }}returns 7
{{str len| café åäö }}returns 8
{{str len| 499-characters... }}returns 499{{str len| 1000-characters... }}returns 500
