CodeConcat v3.0

The State-of-the-Art tool for preparing codebases for LLM usage.

CodeConcat turns your messy project folders into a single, clean, markdown-formatted file optimized for Large Language Models (LLMs) like Claude, GPT-4, and Gemini. It handles parsing, ignoring, and formatting so you don't have to.

🚀 Key Features

• 🧙‍♂️ Interactive Wizard: New in v3.0! Just run codeconcat and let the step-by-step wizard guide you.
• 🌲 ASCII File Tree: Every output starts with a beautiful ASCII representation of your directory structure to give the LLM context.
• 🧠 Smart Context: Automatically respects .gitignore, skipping node_modules, .git, and binary files.
• 💎 Granular Control:
  • Force Include: Bypass .gitignore for specific files (like .env or specific build artifacts) using the new "Force Include" logic.
  • Whitelist/Exclude: Powerful glob patterns for fine-tuning.
• 🛡️ Safe Fencing: Intelligent code block detection prevents nested backticks from breaking your markdown structure.
• ✨ Beautiful UI: Powered by rich and questionary for a modern, clean terminal experience.

📦 Installation

Ensure you have Python 3.8+ installed.

pip install codeconcat

🛠️ Usage

1. Interactive Wizard (Recommended)

Simply run the command without arguments to start the configuration wizard.

codeconcat

You will be asked:

1. Source directory?
2. Output filename?
3. Respect .gitignore?
4. Force include specific files? (Grab those .env files or dist/ builds easily!)
5. Verification & Summary.

2. Command Line Interface (CLI)

For power users or scripts, use the widely compatible CLI.

Concatenate current directory:

codeconcat .

Force Include specific ignored files (New in v3.0): Grab your .env.local even though it's gitignored:

codeconcat --force-include ".env.local"

Exclude logs and include only Python files:

codeconcat . codebase.md -e "*.log" -w "*.py"

Options

📄 Output Format

The output is a single Markdown file structured for maximum LLM comprehension:

1. Header: Project Name.
2. File Tree:

   src/
   ├── main.py
   ├── utils.py
   └── config.py
   

3. Content:

   ### File: `src/main.py`
   
   ```python
   print("Hello World")
