CodeZ CLI – Your Offline Code Companion

🤖 CodeZ CLI – Your Supercharged Offline Coding Buddy! 🚀

Ever wished you had a coding assistant right in your terminal, one that respects your privacy and works offline? Meet CodeZ CLI! 🎉 It's a friendly, conversational code companion powered by local Large Language Models (LLMs) through Ollama, all jazzed up with slick Rich terminal visuals.

Whether you're learning a new language, need a quick code snippet, or want to understand complex code, CodeZ is here to help you out, right from your command line!

✨ Awesome Features ✨

• 🗣️ Conversational REPL: Chat with your code and get context-aware responses.
• ⚡ Lightning Fast: Instant interruption (ESC) and a super responsive UI.
• ✍️ Smart Autocompletion: For commands and file paths, making typing a breeze.
• 💾 Session Savvy: Save your chats and resume them later. Never lose a brilliant thought!
• 📄 File Explorer: Read and display code or any file with beautiful syntax highlighting.
• 🌈 Rich & Beautiful: Enjoy gorgeous markdown, code rendering, and panels in your terminal.
• 셸 Shell Power: Run shell commands directly with ! (e.g., !ls -la).
• 🌐 Web-Savvy (Optional): Enable a web search tool to pull in external knowledge.
• 🧐 Code Analysis (Swift/C): Uses tree-sitter for deeper insights into Swift and C codebases (requires a small helper library).

🚀 Getting Started: Your First Chat in Minutes! 🚀

Ready to team up with CodeZ? Here’s how:

Step 1: Get Your Local LLM Brain 🧠 (Install Ollama)

CodeZ CLI uses Ollama to run powerful language models locally on your machine. This means your code and conversations stay private!

• Head over to ollama.com/download and install it for your operating system (macOS, Linux, Windows).
• Once installed, pull your favorite model. We recommend starting with one like llama3 or mistral:

  ollama pull llama3
  

  (Make sure Ollama is running after installation!)

Step 2: Install CodeZ CLI 💻

This is as easy as pie! 🥧

pip install codez-cli

• For macOS users: If you see an error about an "externally managed environment," it's best to use a virtual environment:

  python3 -m venv ~/codez-venv
  source ~/codez-venv/bin/activate
  pip install codez-cli
  

• What about tree-sitter and ios_lang.so?

  • The pip install command automatically installs tree-sitter, a cool library CodeZ uses for advanced code parsing.
  • For enhanced understanding of Swift and C code, CodeZ uses a special helper library (ios_lang.so).
    • For most users: The core features of CodeZ work perfectly without this. If this specific library isn't pre-built for your system yet, you'll still have a fantastic experience! We're working on making this seamless.
    • For developers: If you want to enable this or contribute, you can build it easily! (See the "For Developers 🤓" section below).

💬 Let's Chat! - Using CodeZ CLI 💬

You're all set! Time to start your first conversation:

Launch CodeZ:

Just type this in your terminal:

codez

You should see a friendly welcome message! Now, just type your questions or commands.

Essential Commands (Your Chat Toolkit):

• Ask anything: Just type your question and press Enter.

  >>> How do I write a "Hello, World!" in Python?
  

• Read a file: Get CodeZ to read a file for you.

  >>> /read path/to/your/file.py
  

• End your chat: Ready to wrap up?

  >>> /endit
  

  (This saves your conversation to the sessions/ directory in your project root – how cool is that?!)
• Clear the screen: Need a fresh slate?

  >>> /clear  # or just 'clr'
  

• Choose your LLM: See available models or switch to a new one.

  >>> /models
  >>> /model -u current_model new_model
  

• Toggle tools: Enable or disable features like web search.

  >>> /tools
  

• Run shell commands: Access your system shell.

  >>> !ls -l
  >>> !git status
  

• Need help? A handy reminder of commands.

  >>> /helpme
  

Quick Example:

>>> What's the syntax for a for-loop in JavaScript?
🤖 CodeZ: [Provides a clear explanation and example]
>>> /read ./my_script.js
🤖 CodeZ: [Displays your script with syntax highlighting] Okay, I've read my_script.js. What would you like to do with it?
>>> Can you explain the main function in this script?
🤖 CodeZ: [Analyzes and explains]
>>> /endit

💪 Superpowers (Advanced Features) 💪

• 🧠 Contextual Memory: CodeZ remembers your conversation (within a configurable token budget) to give you smarter, more relevant answers over time. Oldest parts of the chat are gracefully trimmed if needed.
  • Set your token budget via the CODEZ_MAX_TOKEN_BUDGET environment variable or in the config.
  • Stateless mode is also available: codez --no-memory
• 🗂️ Session Management: Your conversations are automatically saved! You can even load previous sessions to pick up where you left off or provide more context.
  • Session files live in the sessions/ directory (usually in your project's root, or where you run codez).
• ⚙️ Configuration: CodeZ stores its settings (like your preferred model) in a user-friendly location:
  • macOS/Linux: ~/.config/codez/config.json
  • Windows: %APPDATA%\codez\config.json (Thanks to the platformdirs library!)

---

✅ Requirements Checklist ✅

• Python 3.8 or newer
• Ollama installed and running with at least one model (e.g., ollama pull llama3)
• The Python packages rich, prompt_toolkit, platformdirs, and tree-sitter (these are installed automatically when you pip install codez-cli).

🤓 For Developers & Contributors 🤓

Want to peek under the hood, add new features, or fix a bug? Awesome!

Setting Up Your Dev Environment:

1. Clone the repo:

   git clone https://github.com/sam43/code-z-cli.git
   cd code-z-cli
   

2. Create a virtual environment (recommended):

   python3 -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   

3. Install dependencies (including dev tools):

   pip install -r requirements.txt
   # For editable mode, if you plan to make changes to CodeZ itself:
   pip install -e .
   

4. Build the ios_lang.so (for Swift/C parsing): This step is needed if you want to work on or test the Swift/C advanced parsing features. It requires a C compiler.

   python build_language_lib.py
   

   This will create build/ios_lang.so. The app looks for it at ./build/ios_lang.so relative to where core/parser.py is.

Running from Source:

After setup, you can run CodeZ directly:

python -m codechat
# or
python __main__.py

Running Tests:

We use pytest for testing.

# Install pytest if you haven't already (it's in requirements.txt)
# pip install pytest
pytest
# or for more verbose output / specific tests:
PYTHONPATH=. pytest -s tests/core/test_llm_interactive.py

• Note on packaging: venv/, sessions/, and build/ directories should not be included in the distributed PyPI package. vendor/ is needed to build ios_lang.so but isn't strictly a runtime dependency for the app if ios_lang.so is pre-built.
