Design document

This is the first programming languange I've ever made. I don't actually intend to use it for anything, but it's fun to make!

Some of the mottos I try to follow when designing and implementing this languange are:

• Explicit is better than implicit.
• Simple is better than complex.
• Readability counts.
• If the implementation is easy to explain, it may be a good idea.

For those of you familiar with The Zen of Python, these might seem familiar...

This languange is inspired, at least in spirit, by Python. And by Jai in its syntax.

Variables

a: int = 3   ; Definition of integer
a: int = 3.0 ; Invalid: Type mismatch

b: [int] = [1, 2, 3] ; List of ints

Functions

; A function taking an int and a real as arguments and returing an int
function main(a: int, b: real) -> int
{
    return a*b 
}

result := main(1, 2) ; Function call

; A function with no arguments and no return value
function main()
{

}

Branching

if a < 2
{
    return 2
}

Loops

; Loop over list a
for (i : a) 
{
    print(i)
}

; Loop until break
for
{
    if a > 2
    {
        break
    }
}
