Overview

EDL is a simple and lightweight language designed for quickly writing scripts and automations. Its interpreter is written in Rust and allows running scripts via command line or in REPL mode.

---

Installation

1. Prerequisites: Rust and Cargo installed on your machine.

2. Clone the repository:

   git clone https://github.com/Sky-Genesis-Enterprise/edl.git
   cd edl

3. Build the CLI binary:

   cargo build --release -p cli

4. Install the binary:

   mkdir -p ~/.local/bin
   cp target/release/cli ~/.local/bin/edl
   chmod +x ~/.local/bin/edl

5. Add ~/.local/bin to your PATH if not already done:

   echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
   source ~/.bashrc

6. Verify the installation:

   edl --help

Syntax

Variables

Declared with let:

let x = 42;
let name = "EDL";
let is_ready = true;

---

Functions

Defined with fn:

fn greet(name) {
    return "Hello, " + name + "!";
}

let message = greet("World");

---

Control Flow

• if / else condition:

if x > 10 {
    print("x is greater than 10");
} else {
    print("x is 10 or less");
}

• while loop:

let i = 0;
while i < 5 {
    print(i);
    i = i + 1;
}

• for loop with in (if supported):

for item in [1, 2, 3, 4, 5] {
    print(item);
}

---

Data Types

• Numbers: 42, 3.14
• Strings: "text"
• Booleans: true, false
• Lists (example): [1, 2, 3] (if supported)

---

Examples

let x = 10;
let y = 20;
let sum = x + y;

if sum > 25 {
    print("Sum is large");
} else {
    print("Sum is small");
}

---

Using the CLI

• Run a script file:

  edl run my_script.edl

• Interactive REPL mode:

  edl repl

• Show help:

  edl --help
