Template documentation | This template is used on many pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
 | This template uses Lua: |
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
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| {{loop|50|abcdefghij}} }}returns 500{{str len| {{loop|10000|abcdefghij}} }}returns 100000
