pkgx - Universal Tool Runner

The pkgx module provides an interface for the pkgx tool runner, enabling users to fetch and run any open-source utility on-the-fly. It solves the "versioning" and "immediate availability" problems for developers.

When to Activate

  • When the user wants to run a tool once without installing it globally.
  • When testing a specific version of a software (e.g., bun@1.0).
  • When adding temporary tools to the current execution environment.

Core Principles & Rules

  • Non-Invasive: Runs tools without modifying the system's PATH or global configuration.
  • Immediate Execution: Use +pkg to temporarily inject a tool into the environment for a specific command.
  • Zero-Setup: Automatically handles tool acquisition and execution.

Patterns & Examples

Run Without Installation

bash
# Execute bun without installing it to the system
x pkgx bun --eval 'console.log("hello world")'

Temporary Environment Injection

bash
# Temporarily add fzf to the current environment to run a command
eval "$(x pkgx +fzf)"

Interactive Browsing

bash
# Browse all available packages in the pkgx ecosystem
x pkgx ls

Checklist

  • Confirm if the tool is for one-off use or permanent installation.
  • Verify if a specific version of the tool is required.
  • Ensure the user is aware that the environment is not permanently modified.

pufferlib

High-performance reinforcement learning framework optimized for speed and scale. Use when you need fast parallel training, vectorized environments, multi-agent systems, or integration with game environments (Atari, Procgen, NetHack). Achieves 2-10x speedups over standard implementations. For quick prototyping or standard algorithm implementations with extensive documentation, use stable-baselines3 instead.
