AshLang

AshLang is a functional programming language built with Rust.

⚠️Work in Progress⚠️

😎Why I built this?

1. Wanted to explore the process of building a programming language.
2. Just wanted to merge the features of other languages that I love into one language.
   • Simple syntax like Kotlin, Go, V & Zig.
   • Dynamic like Python & JavaScript.
   • Null-Safety like V, Dart & Swift.
   • As Fast as Dart.
3. Because I can 😜

✨Features

• Simple Functional Syntax.
• Dynamic Typing.
• Null-Safety Support.
• Interpreted.
• Language Server Support for VSCode.
  • Syntax Highlighting
  • Code Formatting
• Execution support with Code Runner
• Open Source

🛠️Building

• Tokenizer
• Parser
• Interpreter
• Code Formatter
• LSP Server for VSCode

🤔Usage

Execute the code

ash_lang run ./code.ash

Get Tokens from code

ash_lang run --tkn ./code.ash

Get AST (Abstract Syntax Tree) from code

ash_lang run --ast ./code.ash

Format the code

ash_lang fmt ./code.ash

Data Types

1. Int
2. Double
3. String
4. Boolean
5. List
6. Map

📦Example

// AshLang code to count the occurrence of numbers in a map
fn main(){
  let i = 0, nums = [1, 2, 2, 3, 3, 3], counter = {};
  while (i < len(nums)){
    let num = get(nums, i);
    if (!has(counter, num)){
      counter = set(counter, num, 1);
    } else {
      let val = get(counter, num);
      counter = set(counter, num, (val + 1));
    }
    i += 1;
  }
  println(counter);
}
// {1: 1, 2: 2, 3: 3}
