m moved Template:Str len full/doc to Template:Str len/doc: Moving this over {{str len}}, since that is the better name but this is the better code. Thus merging with {{str len}}. See talk page. |
Changed all references from {{str len full}} to {{str len}} due to move to that name. |

MediaWiki has no parser function or magic word to measure string lengths. And measuring string length using template code is very heavy on the servers. Thus this template is as optimised as possible. But you should consider using {{tl|str ≥ len}} instead, since for most usage cases it is much easier to use and it costs much less server resources. | MediaWiki has no parser function or magic word to measure string lengths.

This template calls {{tl|str len | This template calls {{tl|str len/core}} which does most of the work. For documentation on the internal workings of these two templates see /core. The [[Template talk:Str len|talk page]] might also have more details. | ||
