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.

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| 499-characters... }} returns 499

{{str len| 1000-characters... }} returns 500

Technical details

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