New page

<pre>
Grep( <array>, <pattern>, <flag> )
</pre>

=== Description ===

Returns a new array consisting of the elements of the input arrays values that match the given regex pattern.

=== Parameters ===

==== array ====

The array to use.

==== pattern ====

A regular expression pattern to use.

==== flag ====

Optional; If the flag is higher than 0 the search will be inverted and everything that does not match will be returned instead of everything that does match. (Default is 0)

=== Return Value ===

Success - Returns new array with information.

Failure - Returns empty array.

=== Remarks ===

This also includes Hash values with the array values.

=== Example ===

Return everything that matches

<syntaxhighlight lang="sputnik">
my $array = array( "One" => "Cat", "Two222" => "Fire", "Three" => "FoX", "Four444" => "Water" );
my $lol = GrepKeys( $array, m/\d+/ );
foreach($lol as $key <=> $value)
{
println("$key <=> $value");
}
</syntaxhighlight>

Heres an example of a GrepKeys() created by using Grep()

<syntaxhighlight lang="sputnik">
my $array = array( "One" => "Cat", "Two222" => "Fire", "Three" => "FoX", "Four444" => "Water" );
my $lol = _GrepKeys( $array, m/\d+/ );
foreach($lol as $key <=> $value)
{
println("$key <=> $value");
}

// A custom made reverse Grep for returning matching kesy instead of matching values
Function _GrepKeys( $input, $pattern, $flags = 0 )
{
my $keys = Grep( Keys($input), $pattern, $flags );
my $vals = array();
foreach ( $keys as $key )
$vals[$key] = $input[$key];
return $vals;
}
</syntaxhighlight>
