# proto - Pluggable Multi-Language Version Manager

proto is a next-generation version manager for multiple programming languages. It provides a unified interface for managing Node.js, npm, pnpm, yarn, Bun, Deno, Rust, Go, Python, and 800+ tools via plugins.

## When to Use proto

- Managing language/tool versions across projects
- Pinning versions in `.prototools` for team consistency
- Installing and running tools without global pollution
- Replacing nvm, pyenv, rustup, gvm with a single tool

## Installation

```bash
# Linux, macOS, WSL
bash <(curl -fsSL https://moonrepo.dev/install/proto.sh)

# Specific version, non-interactive
bash <(curl -fsSL https://moonrepo.dev/install/proto.sh) 1.2.3 --yes
```

### Shell Setup

```bash
# Add to shell profile
eval "$(proto activate bash)"   # Bash
eval "$(proto activate zsh)"    # Zsh
```
