 | 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.
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
This is the first general-purpose template to be implemented using mw:Extension:Scribunto. The Lua code is located in Module:String.
