New page

<pre>
$var = function(<args>){<stmList>};
$var(<params>);
</pre>

=== Description ===

Dynamically create function source code and place it in a variable and call it from the variable

=== $var===

The variable to place the function or call the function from.

=== args ===

The functions arguments

=== stmList ===

A list of statements to execute inside the function

=== params ===

Parameters to use when calling the function

=== Return Value ===

Depends what the function returns.

=== Remarks ===

None.

=== Example ===

Basic example

<syntaxhighlight lang="sputnik">
my $Func = Function(){ println("Hello"); };
$Func();
// Prints
// Hello
</syntaxhighlight>

This time with some params

<syntaxhighlight lang="sputnik">
my $Func = Function( $a, $b ){ println("Value is: " . ($a + $b)); };
$Func(10, 20);
// Prints
// Value is: 30
</syntaxhighlight>

Using an array

<syntaxhighlight lang="sputnik">
my $FuncArray = array();
$FuncArray[] = Function(){ println("Hello"); };
$FuncArray[] = Function(){ println("Test"); };
$FuncArray[] = Function(){ println("Cat"); };

foreach($FuncArray as $f)
{
$f(); // Call it
}
// Prints
// Hello
// Test
// Cat
</syntaxhighlight>

Using the @Args variable for infinite paramters

<syntaxhighlight lang="sputnik">
my $Func = [Args("true")]Function(){ printr @Args; };
$Func(1, 3, 8, "Hi");
// Prints
// Array
// (
// [0] => 1
// [1] => 3
// [2] => 8
// [3] => Hi
// )
</syntaxhighlight>

Of course it doesn't have to be on one line

<syntaxhighlight lang="sputnik">
my $Func =
[Args("true")]
Function()
{
$count = count(@Args);
say "There are $count param(s)";
printr @Args;
};

$Func(1, 3, 8, "Hi");
// Prints
// There are 4 param(s)
// Array
// (
// [0] => 1
// [1] => 3
// [2] => 8
// [3] => Hi
// )
</syntaxhighlight>
