Template:Str len/doc
This is a documentation subpage for Template:Str len. It contains usage information, categories and other content that is not part of the original Template page. |
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
[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 1000
