Crust scripting language

Crust Simple toy scripting language, JavaScript-like programming language.

Features

Currently Implemented

• Variables and Constants (set and keep)
• Functions and closures with lexical scoping
• Control Flow (if, elif, else, while)
• Break and Continue statements
• Basic Data Types
  • Numbers ( Integers and Floating Points )
  • Strings
  • Booleans
  • Null
  • Objects
  • Arrays
• Operators
  • Arithmetic (+, -, *, /, %, **, //)
  • Comparison (==, !=, <, >, <=, >=)
  • Compound Assignment (+=, -=, *=, /=, %=, **=, //=)
  • Logical (&&, !!)
  • Unary (!, -, +)
• Exceptions handling with (try, catch, throw)
• Native Functions Support
• Standard Library

Code Examples

# Variables
set x = 10
keep PI = Math.PI

# Functions
fn add(x, y) {
  return x + y
}

# Objects
set person = {
  name: "John",
  age: 30
}

# Control flow
if x > 5 {
  output("x is greater than 5")
} elif x < 5 {
  output("x is less than 5")
} else {
  output("x is equal to 5")
}

# While loops
while x > 0 {
  x = x - 1
  if x == 5 {
    continue
  }
  output(x)
}
