🐲 Leviator

The opinionated programing language

Leviator is compiled to wasm binary format.

Note

This is a student project (EPITECH school). It is not intended to continue this project.

Language Syntax

Important

StringView are not supported.

Important

There is no list/array in this language.

• Comentary

// This is a comment

• Alias

alias A = Int;

• Variables Declaration

@Int a = 1;
@StringView b = "hello";

• Variables Assignment

a = 1;
b = "hello";

• Built-in Types

@Bool a = True;
@Bool b = False;
@Int c = 1;
@Char e = 'a';
@StringView f = "hello";

There is a Void type that can be used to return nothing.

• Function Declaration

fn add(a: Int, b: Int) -> Int
{
    // the next line is the `return`
    <- a + b;
};

export fn sub(a: Int, b: Int) -> Int
{
    <- a - b;
};

• Function Call

add(1, 2);

• Function Polymorphism

fn add(a: Int, b: Int) -> Int
{
    <- a + b;
};

fn add(a: Float, b: Float) -> Float
{
    <- a + b;
};

fn add(a: Int, b: Int, c: Int) -> Int
{
    <- a + b + c;
};

• Conditions

if (a == 1)
{
    // do something
};

if (a == 1)
{
    // do something
}
else
{
    // do something else
};

• Loops

@Int i = 0;
while (i < 10)
{
    // do something
    i = i + 1;
};

• Entrypoint

// If you don't have this function, the program will not be run
export fn start() -> Int
{
    <- 0;
};

• Operators

a + b
a - b
a * b
a / b
a == b
a != b
a < b
a <= b
a > b
a >= b

• Priority of Operators

// realy peticuliar buut we use { for ( and } for )
{a + B} * c
