The Idea

This file will provide you with an idea of the overall design.

This is an entirely new design compared to what was followed till version 0.0.5. The old design was inconsistent and not very compatible with our overall policy.

Variables

The var keyword is used for their definitions, the compiler is supposed to be able to infer the type in case it is not specified (with the obvious condition that the variable must be initialized for its type to be inferred).

// with type
var string_a: str = "hello world!" 

// type can be inferred
var string_b = "hello world!"

You can assign function-like scopes to variables, the return value of that scope will be the assigned value of the variable.

// demo with a quadratic expression
var a = int(input("coefficient of x^2: "))
var b = int(input("coefficient of x:   "))
var c = int(input("the constant c:     "))

// what is the nature of the roots/zeroes/x-intercepts?
var nature_of_root: str = {
    var discriminant = b**2 - 4*a*c
    
    if discriminant < 0
        return "imaginary"
    else
        return "real"
}

the fundamental types are:

Types	Description
bool	true or false
str	string
int	64-bit integer
float	64 bit floating point

Loops

// the type of i can be inferred, no keyword required
for i in 0..100 { ... }

while <condition> {...}

Beside these two traditional loops, there is a third kind, specifically made as a syntactic sugar for tasks where the goal is to simply execute a blob of code a give number of times

// execute the code 100 times, saves some typing time by avoiding the for loop
rep 100 { ... } 

// it can be used this way to repeat a single expression 
print("hello world") rep 100

'rep' stands for repetitions in case you are wondering that
