This script automates the setup of Python virtual environments and installation of required packages. It provides options to specify the virtual environment directory, use development requirements, force package reinstallation, and choose a custom requirements file.

pyenv_bootstrap.sh [OPTIONS]

• -d, --dev: Use development requirements. If specified, the script will look for dev-requirements.txt. If not specified, it will use requirements.txt.
• -f, --force: Force reinstall packages. If specified, packages will be reinstalled even if they are already installed.
• -h, --help: Show help message and usage information.
• -r, --requirements=file: Specify a custom requirements file. If not provided, the script will use either dev-requirements.txt or requirements.txt based on the -d option.
• -p, --venv-dir=directory: Specify the virtual environment directory. The default is venv.

1. Create a virtual environment named "myenv" and install packages from "requirements.txt":

   pyenv_bootstrap.sh -p myenv

2. Use development requirements and force reinstall packages:

   pyenv_bootstrap.sh -d -f

3. Specify a custom requirements file and virtual environment directory:

   pyenv_bootstrap.sh -r custom-requirements.txt -p custom_env

Add these aliases to your .bashrc for easy access to the pyenv_bootstrap.sh script.

alias venv-create='bash /path/to/pyenv_bootstrap.sh'
alias venv-create-dev='bash /path/to/pyenv_bootstrap.sh -d'
alias venv-create-force='bash /path/to/pyenv_bootstrap.sh -f'
alias venv-create-custom='bash /path/to/pyenv_bootstrap.sh -p /path/to/custom_env -r /path/to/custom-requirements.txt'

The script will provide status updates for each step of the process and summarize the operations performed at the end.

~ ❯ venv-create -r /path/to/requirements.txt -p ~/venv
