New page

{{wikipedia|page name}}
{{high-use}}
{{Documentation subpage}}
{{lua|Module:String}}


This is the {{tl|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 {{tl|str ≥ len}}. (See the [[#See also|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:

<pre>
{{str ≠ len | abcde | 5
| Not equal.
| Equal.
}}
</pre>

Which returns this:

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

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

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

Which returns this:

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

<pre>
{{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".
}}
</pre>

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 <nowiki>{{str != len}} or {{str == len}}</nowiki>, but we can't use those template names since they don't work well in MediaWiki.

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