r2md is a simple tool that converts your code repositories into a well-structured Markdown file. Whether you want to document your project, create a readable code overview, or prepare content for training machine learning models, r2md makes the process easy and efficient.

What Problems Does r2md Solve?

• Code to LLM Made Easy: See entire codebase as single .md file.
• Consolidate Code Snippets: Merge code from multiple directories into a single, organized Markdown file.
• Optional PDF Output: Easily create a PDF version of your codebase for sharing or printing.
• Training Data Preparation: Generate JSON files with prompt and completion pairs for SFT training.

Installation

After downloading the r2md binary, place it in your system's PATH to use it from anywhere in the terminal.

How to Use r2md

Once the binary is installed, you can use the r2md command followed by various options to customize its behavior.

Basic Command

Convert the current directory into a Markdown file:

r2md

Specify Directories

Process one or more specific directories:

r2md path/to/dir1 path/to/dir2

Exclude Folders

Exclude certain folders from processing:

r2md -x node_modules -x target

Specify Output File

Define a custom name for the output Markdown file:

r2md -o my_documentation.md

Generate PDF

Create a PDF version of the Markdown output:

r2md -p

Enable Debug Mode

Get detailed output for troubleshooting:

r2md --debug

Generate Training JSON

Create a JSON file with training data using 80 (prompt) /20 (completion) split:

r2md --train-json training_data.json

Combine Options

Use multiple options together:

r2md path/to/dir -x .git -o project_docs.md -p --debug --train-json training.json

Example Usage

1. Generate Markdown from Current Directory:

   r2md
   

   Output: r2md_output.md

2. Generate Markdown and PDF, Excluding node_modules:

   r2md -x node_modules -p
   

   Outputs: r2md_output.md and r2md_output.pdf

3. Generate Training JSON from Specific Directories:

   r2md src tests --train-json training_data.json
   

   Output: training_data.json

Additional Configuration

r2md can be customized using a YAML configuration file (r2md.yml or r2md.yaml). This allows you to define additional ignore patterns and other settings.

Example r2md.yml:

ignore_patterns:
  - "temp"
  - "backup"
