AI Compiler Assistant

A smart, interactive compiler for a custom programming language — complete with lexing, parsing, evaluation, and AI-powered auto-correction.

---

Overview

The AI Compiler Assistant is a browser-based development environment that:

• Lexes, parses and evaluates a custom programming language
• Provides AI-generated corrections, explanations, and optimizations
• Shows a beautifully styled Corrected Code Box
• Lets users auto-replace their code with a single button
• Includes a full Python backend + CodeMirror editor frontend

Custom Programming Language

Example:

integer a = 10;
a = a + 5;
print(a);

Grammar

• PROGRAM → STMT_LIST EOF
• STMT_LIST → (STMT)*
• STMT → DECL | ASSIGN | PRINT_STMT
• DECL → "integer" ID "=" EXPR ";"
• ASSIGN → ID "=" EXPR ";"
• PRINT_STMT → "print" "(" EXPR ")" ";"
• EXPR → TERM { ("+" | "-") TERM }
• TERM → FACTOR { ("*" | "/") FACTOR }
• FACTOR → NUMBER | STRING | ID | "(" EXPR ")"

Backend Architecture

Backend Architecture (Python)

✔ Lexer – Tokenizes input ✔ Parser – Builds an AST ✔ Evaluator – Executes AST + symbol table ✔ AI Assistant Fallback – On failure, returns:

• Errors
• Explanation
• Fix
• Optimization
• Corrected Code

Frontend Features (HTML / JS)

• CodeMirror editor (Dracula theme)
• Live output console
• AI assistant panel
• Clean corrected-code UI
• Buttons:
  • Use corrected code → replaces editor
  • Copy code → clipboard support
