Rekhta – Toy Programming Language
TypeScript-based toy programming language with Urdu syntax designed for compiler construction learning.
Rekhta is an innovative TypeScript-based toy programming language with Urdu syntax, designed specifically for compiler construction learning and making programming accessible to Urdu speakers. The project serves as both an educational tool and a practical implementation of compiler design principles.
The language features LL(1) parsing, Abstract Syntax Tree (AST) construction, comprehensive error handling, and a custom interpreter. The Urdu syntax makes programming concepts more accessible to native Urdu speakers while maintaining the rigor of traditional programming languages.
The project includes a complete compiler pipeline from lexical analysis to code execution, with detailed error reporting and debugging capabilities. The implementation demonstrates advanced concepts in compiler design, language theory, and software engineering.
Technical achievements include implementing a complete lexer and parser, designing an efficient AST structure, creating comprehensive error handling mechanisms, and building a custom interpreter for code execution. The project demonstrates expertise in compiler design, language theory, and educational software development.
