crys 0.1.0

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 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 lib install req py	pip install -r requirements.txt
crys lib install req node	npm install

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 lib install req py            install from requirements.txt (pip)
crys lib install req node          install from package.json (npm)

crys update pip                    upgrade pip itself
crys update npm                    upgrade npm itself
crys update py                     upgrade the Python interpreter
crys update node                   upgrade the Node.js runtime

crys update py lib <name>          pip install --upgrade <name>
crys update node lib <name>        npm install <name>@latest

crys remove py                     uninstall Python (asks to confirm)
crys remove node                   uninstall Node.js (asks to confirm)

crys version py                    print the Python version
crys version node                  print the Node.js version

crys uninstall                     remove Crystal Dependency Manager
crys help                          show help text

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
