CodeDoctor 👩‍⚕️🏥

CodeDoctor is your personal AI-powered coding assistant inside VS Code! Whenever you make a typo, forget a syntax rule, or just can't figure out why your code is covered in red squiggly lines, CodeDoctor is here to diagnose and cure your code!

🎯 The Use Case: Why CodeDoctor?

When you are a beginner or even an experienced developer, you often run into confusing error messages like Unexpected token, ReferenceError, or Expected a closing tag. Usually, you would copy this error, go to Google or StackOverflow, paste your code, and wait to figure out what went wrong.

CodeDoctor changes that! It brings an AI doctor right inside your editor. It reads your error, explains it in very simple, easy-to-understand Hinglish (Hindi + English), and gives you a 1-click button to apply the fix automatically! No more copy-pasting code back and forth.

🚀 Features

• Smart Error Sidebar: All your active file errors are neatly listed in a dedicated CodeDoctor view in the sidebar. No more hunting for red underlines!
• Hinglish Explanations: Explains complex errors in a friendly, conversational Hinglish tone, making it super easy for Indian developers and students to learn.
• 1-Click Apply Fix: Click on any error, read the AI's explanation, and simply click the Apply Fix button to automatically correct your code.
• Fix All Errors ✨: Got a completely messed up file? Click the magic ✨ button in the sidebar to have the AI analyze the entire file and fix ALL errors at once!
• Powered by Gemini AI: Uses Google's ultra-fast Gemini 2.5 Flash model in the backend for lightning-fast responses.

🛠️ Beginner's Guide: How to Get Started

If you are new to VS Code or coding in general, here is what you need to know:

CodeDoctor relies on VS Code to find the errors. VS Code places "red squiggly lines" under your code when something is wrong. For VS Code to know your code is wrong, you need to have the right extensions installed for your programming language!

Step 1: Install Required Language Extensions

• If you code in Python, install the official Python extension by Microsoft.
• If you code in Java, install the Extension Pack for Java.
• If you code in C/C++, install the C/C++ extension.
• (HTML, CSS, and JavaScript are supported out-of-the-box by VS Code, no extra extension needed!)

Step 2: Use CodeDoctor

1. Open a file and intentionally make a mistake (e.g., remove a closing tag in HTML or a semicolon in JavaScript).
2. Save the file. You should see a red squiggly line under the error.
3. Look at the Activity Bar on the far left of VS Code and click the beaker/doctor icon to open the CodeDoctor sidebar.
4. You will see a list of all errors in your current file.
5. Click an error to open the "Explain & Fix" panel. Read the explanation and click "Apply Fix" to inject the correct code.
6. Or, click the ✨ Fix All button at the top of the sidebar to auto-fix the entire file!

✅ What Errors Can It Handle?

CodeDoctor can handle almost any syntax or semantic error that your language server can detect. Examples include:

• Missing closing tags in HTML/XML (</div>)
• Missing brackets or semicolons in C/C++/Java/JS (}, ;)
• Invalid CSS properties or values
• Undefined variables or typos in variable names (ReferenceError)
• Type mismatch errors in TypeScript

❌ What Does It NOT Support?

• Logical Errors: If your code has perfect syntax but does the wrong math (e.g., 2 + 2 = 5), VS Code won't show a red line, so CodeDoctor won't see an error to fix.
• Languages without Language Servers: If you invent a custom language or write in a language (like Rust) but haven't installed the rust-analyzer extension, VS Code won't show errors, and CodeDoctor cannot help.
