Lang

A sort of scripting programming language, that is NOT actually a programming language because it's just transpiling in the background.

TODO / LOG

• [] Transpiler indent <--

• Lexer error on missing string qoutes

• Parser Refactor

  • Function Def

    • Return keyword

  • FunctionCall

  • Assingments

    • Multiple assignments (Sequence doesn't work)

  • Signals <-- This shit too easy

    • Signal Def
    • Signal update
    • Reactive stmt

  • [] Arrays/Indexing <--

• Conditionals

  • If
  • Else
  • Elif

• loops

  • loop
  • while
  • for

Syntax

Not yet decided, but it will be a mix of Svelte, Python, and Rust. (Hot mess)

// This is a comment

1..10 // Range

$a = 1 // Signal
$b = $a // when a changes, b changes
$a = $b // Silly infinite loop (not really)

// Reactive Statements
$ {
    print("Log:", $a, $b) // When a or b changes, this will be executed
}

// Distribute 
// Distribute PI and Coords into the Direction and Distance functions.
// Same as: res = (Direction(PI, Coords), Distance(PI, Coords))
res = PI, Coords -> Direction, Distance; 

// Distribute a arguments as iterable
// Iterate over inputs and outputs and distribute them into f1 and f2
// for args in zip(inputs, outputs): 
//     f1(*args)
//     f2(*args)
|> inputs, outputs -> f1, f2; 

// Deconstruct
user = {"name" : "Jonh", "role" : "Developer" }
{name, role} = user

// Arrow Function
(name, role) => {
    print(name)
    print(role)
}

#[python]
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __str__(self):
        return f"{self.name} is {self.age} years old"
  
#[endpython]

p = Person("Jonh", 21) // Yes, interop with python


// Auto-vars
input("Enter something: ") // _ will contain the input


// Formatting
a = 1
"A's value is %a"
"{a:02d}" // 01
