crys 0.1.4

One short CLI for pip/npm/node/python chores

Crystal Dependency Manager (crys)

One short command instead of remembering different pip/npm invocations.

Install

cd crystal-dependency-manager
pip install .

This registers a crys command on your PATH (via Python's normal console-scripts mechanism).

Why

crys doesn't reinvent pip/npm/apt/brew/choco — it just remembers the long command for you and runs it. A few examples of what's actually happening behind the scenes:

You type	crys runs (depending on your OS/tools)
crys update pip	python -m pip install --upgrade pip
crys update npm	npm install -g npm@latest
crys update py	sudo apt update && sudo apt install --only-upgrade python3 (or brew upgrade python, choco upgrade python, ...)
crys update node	sudo apt install --only-upgrade nodejs (or brew upgrade node, choco upgrade nodejs, ...)
crys update rust	rustup update (or brew upgrade rust, choco upgrade rust, ...)
crys remove py	sudo apt remove python3 (or brew uninstall python, choco uninstall python, ...) — with a confirmation prompt first
crys remove node	brew uninstall node / apt remove nodejs / choco uninstall nodejs — with a confirmation prompt first
crys remove rust	rustup self uninstall -y (or brew uninstall rust, choco uninstall rust, ...) — with a confirmation prompt first
crys install node	brew install node / sudo apt install nodejs npm / choco install nodejs / winget install OpenJS.NodeJS — only if Node isn't already there
crys install rust	the official curl | sh installer from rustup.rs — only if Rust isn't already there
crys install py	nothing — prints why crys can't bootstrap its own interpreter, and where to get Python
crys lib install req py	pip install -r requirements.txt
crys lib install req node	npm install
crys lib install req rust	cargo fetch

Every run also prints the exact command it's about to execute (the cyan $ ... line), so you can see what actually happened and learn the "real" command if you ever need it without crys.

Commands

crys install node                  install Node.js if it's missing
crys install rust                  install Rust (via rustup) if missing
crys install go                    install Go if it's missing
crys install ruby                  install Ruby if it's missing
crys install php                   install PHP if it's missing
crys install py                    explains why crys can't do this one

Notes on the risky commands

• crys update node / crys update py try, in order: nvm/pyenv (if present, they just print the right follow-up command since those are shell functions, not real executables), then brew on macOS, then apt/dnf/pacman on Linux, then choco/winget on Windows.
• crys remove node / crys remove py always ask for confirmation first. crys remove py on Linux refuses to run automatically, since removing the system Python package can break the OS — it prints the manual command instead.
• Everything shells out to the real tool (pip, npm, brew, apt, etc.) rather than reimplementing package management, so crys stays a thin, predictable wrapper.

Uninstalling

crys uninstall

or manually: pip uninstall crystal-dependency-manager
