A Pi extension that integrates RustDex - a high-performance, universal code indexer and semantic search tool - directly into your Pi agent workflow.

What does this do? RustDex creates a searchable index of your codebase, allowing Pi to find functions, classes, and API endpoints using plain English queries like "show me where we handle user authentication" instead of guessing file names.

Acknowledgment: RustDex is a complete re-implementation in Rust based on the excellent concepts from SymDex by Husnain. The original SymDex project pioneered the idea of universal code indexing with semantic search, and RustDex builds on those foundations with improved performance and cross-platform support.

• 🚀 Index Codebases: Create searchable indexes of your projects with a single command
• 🔍 Symbol Search: Find functions, classes, and methods by exact name across repos
• 🧠 Semantic Search: Search code by natural language descriptions using local BERT embeddings
• 🌐 API Route Extraction: Automatically identify HTTP endpoints in web frameworks
• 📁 Repository Management: List and manage all your indexed repositories
• 📖 Symbol Reading: Read exact symbol source code using byte ranges (token-efficient)
• 🔧 Backward Compatible: Automatically detects CLI version and adapts to available features

Just run this single command - it installs everything you need:

pi install npm:pi-rustdex

That's it! The RustDex binary will be automatically installed (if not already present) during the installation process. You can verify everything is working by typing /rustdex-status in any Pi session.

When you run pi install npm:pi-rustdex:

1. The Pi extension is installed - This gives Pi access to RustDex tools
2. The RustDex binary is automatically checked - If it's not installed, it will be installed via npm
3. You're ready to go - No additional steps required!

The automatic installation should handle everything, but if you need to manage the RustDex binary manually, here are the commands:

Install RustDex binary manually:

npm install -g rustdex

Uninstall RustDex binary:

npm uninstall -g rustdex

Check RustDex version:

rustdex --version
# Should output: rustdex 0.4.1 or later

The npm package automatically detects your platform and downloads the appropriate binary:

• macOS (ARM64/x64)
• Linux (ARM64/AMD64)
• Windows (ARM64/AMD64)

If you prefer to download the binary directly (without npm), you can get it from the RustDex Releases page. The latest release includes binaries for all platforms.

macOS (Apple Silicon):

curl -L -o rustdex.zip https://github.com/burggraf/rustdex/releases/download/v0.4.1/rustdex-v0.4.1-darwin-arm64.zip
unzip rustdex.zip
chmod +x rustdex
sudo mv rustdex /usr/local/bin/
rm rustdex.zip

Linux (x86_64):

curl -L -o rustdex.zip https://github.com/burggraf/rustdex/releases/download/v0.4.1/rustdex-v0.4.1-linux-amd64.zip
unzip rustdex.zip
chmod +x rustdex
sudo mv rustdex /usr/local/bin/
rm rustdex.zip

Windows (x86_64):

curl -L -o rustdex.zip https://github.com/burggraf/rustdex/releases/download/v0.4.1/rustdex-v0.4.1-windows-amd64.zip
Expand-Archive -Path rustdex.zip -DestinationPath .
Move-Item -Path .\rustdex.exe -Destination C:\Windows\System32\
Remove-Item rustdex.zip

Add to your project's pi.json:

{
  "extensions": ["npm:pi-rustdex"]
}

This will load the extension automatically when you start Pi in that project directory.

Once installed, verify everything is working by typing this in any Pi session:

/rustdex-status

You should see a notification confirming that RustDex is installed and ready to use.
