{{lua|Módulo:String}}
== Descrição ==
Esta é a meta-predefinição {{Lp|str ≥ len}}

Ela ajuda outras predefinições a determinar se uma ''[[string]]'' é maior/igual ou menor que um dado comprimento.

=== Uso ===
{{em tradução}}

This template takes 3 to 4 unnamed parameters.

Here is how to check if the string "abcde" is 4 characters or more:

<pre>
{{str ≥ len | abcde | 4
| Equal or longer.
| Shorter.
}}
</pre>

Which returns this:

:{{str ≥ len | abcde | 4
| Equal or longer.
| Shorter.
}}

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 100 characters or more:

<pre>
{{str ≥ len 
| 1 = ab=cde 
| 2 = 100
| 3 = Equal "=" or longer.
| 4 = Shorter, not "=".
}}
</pre>

Which returns this:

:{{str ≥ len 
| 1 = ab=cde 
| 2 = 100
| 3 = Equal "=" or longer.
| 4 = Shorter, not "=".
}}

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.

=== Parâmetros ===

Detailed parameter explanation:

<pre>
{{str ≥ len 
| 1 = A string
| 2 = A length
| 3 = Data to return/render when "longer than or equally long".
| 4 = Data to return/render when "shorter than".
}}
</pre>

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

Length values below 0 are considered to be 0.

=== Detalhes técnicos ===
The potential alternative templates names <nowiki>{{str >= len}} or (for the opposite) {{str < len}}</nowiki> do not work in MediaWiki.

Even though this is a string handling template it uses very efficient code. (While some of the other string handling templates are probably so heavy on the servers that we perhaps should not use them.)

[[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.
