langchain-code 0.1.6

A comprehensive combination of all agentic CLI at one place with 🦜🔗!

LangCode

The only CLI you'll ever need!

LangCode is the "one-key" developer CLI that unifies Gemini, Anthropic Claude, OpenAI, and Ollama with ReAct & Deep modesΓÇöfully inline, right in your terminal.

Get Started

Installation:

pip install langchain-code

Launch the Interactive Launcher:

Just type langcode in your terminal and hit Enter. This opens a user-friendly interactive menu where you can easily configure your session and access various functionalities without needing to remember specific command-line arguments. See the image shown above.

Interactive Mode

The interactive mode serves as the central hub for all your coding tasks. It allows you to:

• Choose a Command: Select what you want to do: chat, feature, fix, or analyze.
• Configure the Engine: Pick between react (fast and efficient) and deep (for complex tasks).
• Enable Smart Routing: Let LangCode automatically select the best LLM for each task.
• Set the Priority: Optimize for cost, speed, or quality when using smart routing.
• Manage Autopilot: Enable fully autonomous mode for the Deep Agent (use with caution!).
• Toggle Apply Mode: Allow LangCode to automatically write changes to your file system.
• Select an LLM: Explicitly choose between Anthropic and Google Gemini, or let LangCode decide.
• Specify the Project Directory: Tell LangCode where your codebase is located.
• Edit Environment Variables: Quickly add or modify API keys and other settings in your .env file.
• Customize Instructions: Open the .langcode/langcode.md file to add project-specific guidelines.
• Configure MCP Servers: Set up Model Context Protocol (MCP) servers for advanced tool integration.
• Edit Language Code: Modify the core language code directly from the main window.
• Specify MCP Servers: Configure Model Context Protocol (MCP) servers for advanced tool integration.
• Define a Test Command: Specify a command to run after making changes (e.g., pytest -q).
• Access Help: Press h to toggle help and q or Esc to quit.

Core Commands

While the interactive launcher is the recommended way to use LangCode, you can also use the following commands directly from the terminal:

• langcode chat: Starts an interactive chat session.
• langcode feature: Implements a new feature.
• langcode fix: Fixes a bug.
• langcode analyze: Analyzes the codebase.
• langcode instr: Opens the project instructions file.
