OkLang

OkLang is an interpreted Turing Complete programming language, created as a minor semester project. Ok_Lang is built as a minimalistic language with decent Runtime, Parsing and Syntax Error handling.

Features

• Dynamic Type.
• Scalar values (Number, String, Boolean).
• Block variable scope.
• User-defined and Built-in functions with closure.
• Control Flow (Branching and Looping).
• Expression Evaluation as per standard precedence.

Installing / Building

Use Latest JDK version for best support. (JDK 18.0.x used during development)

git clone https://github.com/gitKashish/ok_lang

Build using the provided bash script or manually compile package.

bash ./build_ok.sh

Running .ok programs.

Run the following command without source file to run REPL.

bash ./ok.sh source/code/file/path.ok

Basic Syntax

• Variables are by default initialized to nil.
• print and clock are the only two built-in functions at the moment.

Declaring variable

// This is a comment.
// It only works for a single line.

Declaring variable

var myVariable;
myVariable = 10 * 20 + (10 - 10);

Branching Control Flow

if (expression) { ... }

Looping Control Flow

while (expression) { ... }

for (decl; expression; increment/decrement) { ... }

Function Declaration

fun functionName (argument/s) {
  ...
  return expression;
}
