Custom Language Compiler

A web-based compiler that translates code written in a simple custom programming language into multiple target programming languages (JavaScript, Python, C++, Java, and C).

Features

• Simple Custom Language Syntax:

  • maano - Variable declaration
  • likho - Print statement
  • agar - If condition
  • warna - Else statement
  • jabtak - While loop

• Multi-Language Support:

  • JavaScript (with live execution)
  • Python
  • C++
  • Java
  • C

• Interactive Web Interface:

  • Real-time code conversion
  • Live output for JavaScript execution
  • Syntax highlighting
  • Modern, responsive design

Example Code

Here are some examples of how to use the custom language:

1. Basic Variable Declaration and Printing

maano x = 5
likho x

2. Arithmetic Operations

maano first = 10
maano second = 20
maano sum = first + second
likho "Sum of two numbers is:"
likho sum

3. Conditional Statements

maano x = 5
maano y = 10
agar x < y {
    likho "x is less than y"
} warna {
    likho "x is greater than or equal to y"
}

How to Use

1. Open index1.html in a web browser
2. Write your code in the custom language syntax in the textarea
3. Select your target programming language from the dropdown
4. Click "Run Code" to:
   • See the converted code in your chosen programming language
   • See the output (if JavaScript is selected)

Project Structure

• index1.html - The main web interface
• script.js - Contains the compiler implementation (lexer, parser, and code generator)
• styles.css - CSS styling for the web interface

Technical Implementation

The compiler works in three main stages:

1. Lexical Analysis (Lexer):

   • Breaks down input code into tokens
   • Identifies keywords, identifiers, numbers, and operators

2. Syntax Analysis (Parser):

   • Converts tokens into an Abstract Syntax Tree (AST)
   • Validates the program structure

3. Code Generation:

   • Converts the AST into target programming language code
   • Handles language-specific syntax and features

Browser Compatibility

The compiler works in all modern web browsers:

• Google Chrome
• Mozilla Firefox
• Microsoft Edge
• Safari

Notes

• JavaScript mode provides live execution in the browser
• For other languages, the compiler generates equivalent code that can be run in their respective environments
• The project uses a clean, minimalist design with a matrix-inspired background
