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
my $Func = Function(){ println("Hello"); }; $Func(); // Prints // Hello
This time with some params
my $Func = Function( $a, $b ){ println("Value is: " . ($a + $b)); }; $Func(10, 20); // Prints // Value is: 30
Using an array
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
Using the @Args variable for infinite paramters
my $Func = [Args("true")]Function(){ printr @Args; }; $Func(1, 3, 8, "Hi"); // Prints // Array // ( // [0] => 1 // [1] => 3 // [2] => 8 // [3] => Hi // )
Of course it doesn't have to be on one line
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 // )
