Predloga:Str ≠ len

Dokumentacija za predlogo[poglej] [uredi] [zgodovina] [osveži]

This is the {{str ≠ len}} meta-template.

It helps other templates check if a string is "not equal" vs. "equal" to a given length.

Note! For most usage cases it might be better to use {{str ≥ len}}. (See the see also section below.)

Usage

This template takes 3 to 4 unnamed parameters.

Here is how to check if the string "abcde" is exactly 5 characters:

{{str ≠ len | abcde | 5
| Not equal.
| Equal.
}}

Which returns this:

Equal.

Templates have a problem to handle parameter data that contains equal signs "=". But that is easily solved by using numbered parameters. Here we check if the string "ab=cde" is exactly 100 characters:

{{str ≠ len 
| 1 = ab=cde 
| 2 = 100
| 3 = Not equal, "!=".
| 4 = Equal, "=".
}}

Which returns this:

Not equal, "!=".

It probably is a good habit to always use the numbered parameters, since you might not know beforehand exactly how the data will look that your template will feed to this meta-template.

Parameters

Detailed parameter explanation:

{{str ≠ len 
| 1 = A string
| 2 = A length
| 3 = Data to return/render when "not equally long".
| 4 = Data to return/render when "equally long".
}}

Empty or undefined strings are considered to be of 0 length.

Length values below 0 are considered to be 0.

Technical details

This template would be equivalent to templates named {{str != len}} or {{str == len}}, but we can't use those template names since they don't work well in MediaWiki.

Templates have problems to handle parameter data that contains pipes "|", unless the pipe is inside another template {{name|param1}} or inside a piped link [[Help:Template|help]]. Thus templates can not handle wikitables as input unless you escape them by using the {{!}} template. This makes it hard to use wikitables as parameters to templates. Instead the usual solution is to use "HTML wikimarkup" for the table code, which is more robust.
