Python 3 venv wrapper. Manages all virtual environments under ~/.venv/ .

venv_wrapper

# venv_wrapper, manage all virtual environments under ~/.venv/
# Include the following in .bashrc / .bash_profile / .zshrc
# See https://gist.github.com/dbtek/fb2ddccb18f0cf63a654ea2cc94c8f19
#
# Usage:
# $ mkvenv myvirtualenv   # creates venv under ~/.venv/
# $ venv myvirtualenv     # activates venv
# $ deactivate            # deactivates venv
# $ rmvenv myvirtualenv   # removes venv
# $ rmvenv env1 env2      # removes multiple venvs
# $ lsvenv                # lists all venvs

export VENV_HOME="$HOME/.venv"
[[ -d $VENV_HOME ]] || mkdir -p $VENV_HOME

lsvenv() {
  ls -1 "$VENV_HOME"
}

venv() {
  if [ $# -eq 0 ]; then
    echo "Please provide venv name"
  elif [ -d "$VENV_HOME/$1" ]; then
    source "$VENV_HOME/$1/bin/activate"
  else
    echo "Virtual environment '$1' does not exist."
  fi
}

mkvenv() {
  if [ $# -eq 0 ]; then
    echo "Please provide venv name"
  else
    if [ -d "$VENV_HOME/$1" ]; then
      echo "Virtual environment '$1' already exists."
    else
      echo "Creating venv under $VENV_HOME/$1"
      python3 -m venv "$VENV_HOME/$1"
      echo "Activating $1"
      venv "$1"
    fi
  fi
}

rmvenv() {
  if [ $# -eq 0 ]; then
    echo "Please provide one or more venv names"
  else
    current_venv=$(basename "${VIRTUAL_ENV:-}")
    for env in "$@"; do
      if [ -d "$VENV_HOME/$env" ]; then
        if [ "$env" = "$current_venv" ]; then
          deactivate
          echo "Deactivated current virtual environment '$env'."
        fi
        rm -rf "$VENV_HOME/$env"
        echo "Virtual environment '$env' removed."
      else
        echo "Virtual environment '$env' does not exist."
      fi
    done
  fi
}

complete -C lsvenv venv
complete -C lsvenv rmvenv

So glad I found this when I searched for "venv wrapper", works perfectly. Thanks!

Thanks for this! I found it handy to add an lsvenv command as well to list the existing virtual environments under ~/.venv/

lsvenv() {
  ls -1 $VENV_HOME
}

Thanks @zekefarwell. Added lsvenv.

Useful gist 👍 . I added complete -W "`lsvenv`" venv to the end of it so venv can autocomplete with the tab key. It might help you out.

This is great! My system version is 3.10 which tends to break things, so I added a few lines so mkvenv can optionally set the version. It's a bit fragile and basic, but it works for my purposes.

mkvenv() {
  if [ $# -eq 0 ]
    then
      echo "Please provide venv name"
  elif [ $# -eq 1 ]
    then
      python3 -m venv $VENV_HOME/$1
  elif [ $# -eq 2 ]
    then
      python$2 -m venv $VENV_HOME/$1
  fi      
}

the ZSH equivalent for @leoschmitz 's one liner above is
compdef '_path_files -/ -W $VENV_HOME' venv

Autocompletion added for venv and rmvenv commands. Thanks @leoschmitz, @billyzs.
Auto activating newly created venv with mkvenv is also added along with some informative messages.

Changes and Improvements:

Error Checking:

• Added mkdir -p $VENV_HOME to ensure the directory structure is created if it doesn't exist.
• Added checks to ensure that the virtual environment exists before attempting to activate or remove it.

User Feedback:

• Added feedback messages to inform the user about the creation and deletion of virtual environments.

Multiple Environment Deletion:

• Enhanced rmvenv function to accept multiple arguments, allowing deletion of multiple virtual environments in a single command.
• Added loop in rmvenv to iterate over all provided virtual environment names, checking for their existence and deleting them if they exist.

Deactivation Before Deletion:

• Added logic to deactivate the currently active virtual environment if it is one of the environments being deleted.

Improved Comments:

• Enhanced script comments for better clarity and understanding of usage.
