Anonymous functions

Anonymous functions are functions that don't have a name, and they are defined inside another function. Anonymous functions are useful when you want to pass a function as an argument to another function, or when you want to return a function from another function.

Syntax

Anonymous functions have parameters and a body. The parameters are the same as local functions, and the body is the same as local functions. The only difference is that the function name is missing.

~main<argc><argv>{<
    <param1><param2><param3>{</* The block */>};
>}

Take no arguments

There is a difference between local functions and anonymous functions if you want to make it take no arguments, you need to add <> before the block.

Return values

Anonymous functions can return values, just like local functions, you can return a value by using the return keyword.

~main<argc><argv>{<
    <>{<return 1;>};
>}

Call anonymous functions

To call an anonymous function, you just need to call it like a [local function]. Add <> to call it without arguments, or add <arg1><arg2><arg3> to call it with arguments.

~main<argc><argv>{<
    hello = <>{<return "Hello world!";>}<>;
    println<hello>;
>}

Output:

Hello world!

Assign anonymous functions to variables

You can assign anonymous functions to variables, like the example below.

~main<argc><argv>{<
    say_hello = <name>{<println<format<"Hello {}"><name>;>;>};
    say_hello<"Ahmed">;
>}
