మూస:str len
- The following documentation is located at Template:str len/doc. [edit]
- Note: Please move the documentation subpage to Template:str len/documentation.
This is the {{str len}} meta-template.
It takes a string as parameter and returns its length (after stripping any leading and/or trailing whitespace). It can count up to 500 in length, and returns 500 for strings that are too long.
It must be subst:'d, so is only useful in new-entry-creation templates, subst:'d templates, and so on.
Examples
[<small>మార్చు</small>]If the parameter is empty or undefined it is considered to be of zero length:
{{subst:str len}}becomes 0{{subst:str len|}}becomes 0{{subst:str len| }}becomes 0
It counts the length correctly, even if the string contains spaces, looks like a number, or contains special characters:
{{subst:str len| ab cde }}becomes 6
{{subst:str len| 1234567 }}becomes 7
{{subst:str len| café åäö }}becomes 8
It can measure strings up to 500 in length, and returns 500 for strings that are too long:
{{subst:str len| 499-characters... }}becomes 499{{subst:str len| 1000-characters... }}becomes 500
Technical details
[<small>మార్చు</small>]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, even though optimized about as much as it can be, must, by community decision, be subst:'d.
This template substitutes {{str len/core}}, which does most of the work. For documentation on the internal workings of these two templates see /core.
