This template employs some extremely complicated or esoteric features of template syntax. Please do not attempt to alter it unless you are certain that you understand the setup and are prepared to repair/revert any consequent collateral damage if the results are unexpected. Any experiments should be conducted in a sandbox or your userspace.

This is the {{Str len full}} meta-template.

It takes a string as parameter and returns its length. It can count up to 500 in length, and returns 500 for strings that are too long.

Note! For most usage cases it is much easier and costs much less server resources to use {{Str ≥ len}} or one of its sister templates. See the see also section below.

Examples

If the parameter is empty or undefined it is considered to be of zero length:

{{str len full}}, {{str len full|}}, {{str len full| }}

Template:Str len full, Template:Str len full, Template:Str len full

This template counts the length of the string, even if it contains spaces or looks like a number:

{{str len full| ab cde }}, {{str len full| 1234567 }}

Template:Str len full, Template:Str len full

It can measure strings up to 500 in length, and returns 500 for strings that are too long:

{{str len full| 499-characters... }}, {{str len full| 1000-characters... }}

Template:Str len full, Template:Str len full
