Overview

TesLang is a custom language designed to help users understand the basics of compiler construction. It includes a lexer, parser, semantic analyzer, and intermediate representation (IR) generator. This project demonstrates the front-end compilation process, turning source code into an intermediate representation.

Features

• Lexer: Tokenizes the input source code.
• Parser: Generates an abstract syntax tree (AST) from the tokenized input.
• Semantic Analyzer: Performs type checking and scope management.
• Intermediate Representation (IR) Generator: Converts the AST into an intermediate representation for further processing.

Installation

1. Clone the repository:

   https://github.com/MortezaPr/Teslang.git
   cd Teslang

2. Install the required packages:

   pip install -r requirements.txt

Usage

To compile a TesLang source file, use the main.py script. Ensure you have a TesLang source file named teslang_source.txt in the same directory as main.py.

python main.py

Modules

Lexer (lexer.py)

Tokenizes the input source code using PLY (Python Lex-Yacc).

Tokens (tokens.py)

Defines the tokens and reserved words used in the language.

Parser (parser.py)

Parses the tokenized input to generate an abstract syntax tree (AST).

Semantic Analyzer (semantic_analyzer.py)

Performs type checking and manages the symbol table.

Abstract Syntax Tree (AST) (ast.py)

Defines the AST node classes used by the parser and semantic analyzer.

Intermediate Representation (IR) (ir.py)

Defines the IR node classes used by the IR generator.

IR Generator (ir_generator.py)

Generates the intermediate representation from the AST.

Symbol Table (symbol_table.py)

Manages the symbols and their attributes during semantic analysis.

Main Script (main.py)

The entry point for the compiler, which ties together the lexer, parser, semantic analyzer, and IR generator.

Example

Create a TesLang source file named teslang_source.txt with the following content:

fn add(a as int, b as int) <int>
{
    result :: int = a + b;
    return result;
}

Run the compiler using the following command:

python main.py
