Turkish-Inspired Programming Language

Course Information

• Course: Programming Language
• Project: Term Project
• Implementation Language: Java

Overview

This project is a mini programming language inspired by Turkish syntax and keywords. The goal is to design and implement the core front-end components of a compiler.

Implemented Components

• Lexical Analyzer (Lexer)
• Recursive Descent Parser
• Symbol Table
• Syntax Error Detection
• Test Case Execution with Sample Source Files

Language Features

• Variable Declarations
• Assignment Statements
• Arithmetic Expressions
• Conditional Statements (if / else)
• Loop Structures (while)
• Block Scope with Braces

java -cp src Main

Example Syntax

tam x;
x = 5 + 3;

eger (x > 5) {
   yaz x;
}

Component Responsibilities

• Main.java → Starts program execution and loads input files.
• Lexer.java → Converts source code into tokens.
• Token.java → Stores token type and value.
• TokenType.java → Defines all token categories using enum.
• Parser.java → Validates syntax using Recursive Descent Parsing.
• SymbolTable.java → Stores declared identifiers and metadata.

Development Status

In Progress 🚧
