Projects/pyv

Ok so this is a project to make a python installer that works like this

> brew install pyv
> apt install pyv

Then

> pyv latest

will install the latest version of python.

Let's make a script called pyv.sh for starters

Here it is

#!/usr/bin/env bash

pyv_install() {
  echo do install here ver $1
}

pyv_list() {
  echo list versions
}

if test $# -eq 0; then
  echo "usage: pyv <version>"
else
  case "$1" in
    list) pyv_list $@; exit;;
    *) pyv_install "$1"; exit;;
  esac
fi

Meanwhile I installed python-build from pyenv and used that to install python 3.11.1 to /usr/local in docker:

docker run -it ubuntu

That's a bit messy but it's got the right parts. Now just need a way to resolve the latest version, and the prototype of this script is pretty much done.
