Operators

Melang supports these operators as shown below:

operators	combination direction
,	left to right
= += -=  »= «= *= /= |= &= ^= %=	right to left
&& ||	left to right
& | ^	left to right
== !=	left to right
> >= < <=	left to right
>> «	left to right
+ -	left to right
* / %	left to right
!	-
++ – (suffix)	-
[] .	left to right
- ~ & $ () ++ – (prefix)	-

These operators are listed by priority from low to high.

Examples

Here, it is assumed that you have already installed Melang and all its library files (installed using the make all command).

The sys.print will output the contents of the parameter to the terminal.

sys = Import('sys');

i = 1, 2, 3;
sys.print(i); // 1

i += 1;
sys.print(i); // 2

b = i == 2; //b is a boolean value
sys.print(b); // true

i = i | 1;
sys.print(i); // 3

sys.print(i++); // 3

sys.print(++i); // 5

sys.print(i--); // 5

sys.print(--i); // 3

sys.print(i == 3 && 100 || 50); // 100

human { // set definition
  name;
  age;
}
friend = $human; //instantiate a human object
friend.name = 'Alex';
friend.age = 18;
sys.print(friend.name); // Alex
sys.print(friend.age); // 18

sys.print(!friend.age); //false

arr = [1, 2, 3];
sys.print(arr[2]); // 3

The output is:

1
2
true
3
3
5
5
3
100
Alex
18
false
3
