Python version & venv management (maybe more ...)

Use pipx (recommend)

pipx install pvx

Or pip

pip install pvx

Don't forget python-build and it dependencies.

git clone https://github.com/pyenv/pyenv.git ~/.pyenv

pyenv is usually installed at ~/.pyenv by default. If it is installed silently, then everything is ready, otherwise add PVX_PY_BUILD_PATH=/your/pyenv/path/plugins/python-build to env (plugins/python-build is usually fixed).

• List version number that you can download.

  pvx py archive 
  
  # If you want to filter it, do this
  pvx py archive 3.10

• Install.

  pvx py insetall 3.10.4

• List versions of installed.

  pvx py list

• Remove the specified version of Python.

  pvx py remove 3.10.4

• Create a virtual environment (pvx use Python Venv and compatible with its parameters)

  # All default (current python and default venv prompt)
  pvx venv new
  
  # Specify the version (which install by pvx)
  pvx venv new 3.10.4
  
  # Use existing Python
  pvx venv new ~/.pyenv/versions/3.10.4/bin/python
  
  # Use venv's parameters, such as specifying prompt
  pvx venv new 3.10.4 --prompt venv_prompt_name
  
  # Use current python and venv's parameters
  pvx venv new --prompt venv_prompt_name

• List all virtual environments

  # You'll see a table , highlight the activate one.
  pvx venv list

• Activate virtual environment with PROMPT

  # use `pvx venv list` to show prompt
  pvx venv activate prompt_name

• Remove virtual environment with PROMPT

  # use `pvx venv list` to show prompt
  pvx venv remove prompt_name

• PVX_ROOT_PATH: pvx home path. Default: ~/.pvx
• PVX_PYTHON_INSTALLATION_PATH: The installation folder for Python. Default: ~/${PVX_ROOT_PATH}/versions
• PVX_VENV_IN_PROJECT: Whether the virtual environment is installed in the project. Default: true
• PVX_VENV_DIR_NAME_IN_PROJECT: The folder name of virtual environment. Default: .venv
• PVX_VENV_EXTERNAL_PATH: If PVX_VENV_IN_PROJECT is false, the virtual environment is installed externally rather than in the project. Default: ~/${PVX_ROOT_PATH}/venv
• PVX_PY_BUILD_HOME: pyenv plugin python-build home path. Default: ~/.pyenv/plugins/python-build

If you want to extend commands, be familiar with the following points.

1. The folder where the pvx.py file resides is the root.
2. root/commands is the folder where the .py command scripts are stored.
3. If filenamed is true, use the file name command, otherwise use the argument to @click.command. - The .py files are named pvx_{group}_{command}.py.For example: pvx_py_install.py, which means we can call it with pvx py install.
4. .py file must have a method called cli and decorated with @click.command .

pvx was my experiment after studying pyenv, poetry rich and click. Thank them for their efforts, fun 😁 ~

• python-build (pyenv's plugin), which pvx depend to install different versions of Python
• poetry
• rich, a Python library for rich text and beautiful formatting in the terminal.
• click, a python composable command line interface toolkit
