This template is used in system messages , and on approximately 19,000 pages ./sandbox or /testcases subpages, or in your own user subpage . The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.
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 0It 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 1000ഫലകത്തിനുള്ള ചരങ്ങൾ
