# Repo2Docs: Convert GitHub Repositories to Documentation

Inspired by [github2file](https://github.com/cognitivecomputations/github2file)

Repo2Docs is a Python-based tool designed to convert the contents of a GitHub repository into comprehensive documentation or diagrams. This tool leverages language model APIs such as OpenAI or Anthropic to process and generate documentation, making it easier for developers to create documentation for their projects.

## How It Works

```mermaid
sequenceDiagram
    participant U as User
    participant Main as Main Script
    participant RP as RepoProcessor
    participant TD as TextToDocs
    participant LLM as LLMClient
    U->>Main: Execute with parameters
    Main->>RP: Process repository
    RP->>Main: Return processed text
    Main->>TD: Request documentation type
    TD->>LLM: Request LLM generation
    LLM->>TD: Return generated content
    TD->>Main: Return documentation
    Main->>U: Save documentation to file
```
*Caption: This sequence diagram illustrates the flow of interactions from the user executing the script to the generation and saving of documentation.*


## Using Repo2Docs

To run Repo2Docs on your local machine, follow these steps:

1. **Install Repo2Docs**:
   ```
   pip install repo2docs
   ```


2. **Set Up Environment Variables**:
   Export your OpenAI and Anthropic API keys as environment variables:
   ```
   export OPENAI_API_KEY=your_openai_api_key_here
   export ANTHROPIC_API_KEY=your_anthropic_api_key_here
   ```

3. **Run the Tool**:

   cd into the directory where the repo is located
   ```
   cd <path_to_repo>
   ```
   Run the following command to generate documentation:
   ```
   repo2docs --dir_path . --output_file documentation.md --type documentation --llm openai
   ```

   To generate mobile documentation, use `--type mobile`.
   To generate diagrams instead of documentation, use `--type diagram`.
   To generate database erd diagrams, use `--type database`.
   To use a custom prompt, use `--prompt <prompt>`.

## Supported File Types

Repo2Docs currently supports processing files with the following extensions: `.py`, `.js`, `.jsx`, `.ts`, `.tsx`, `.c`, `.cpp`, `.h`, `.hpp`. It filters out files from directories like `docs`, `examples`, `tests`, and others that are unlikely to contain useful information for documentation.
