Template:Used in system

Gnome-utilities-terminal.svg 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
