Easily switch pyenv virtualenvs with peco

[Addition] I have released a generalized version of this that can be used in rbenv etc., so I think you should use this.

giginet/peco-anyenv

.zshrc

function venv() {
    venvs=`pyenv versions | peco`
    venv0=`echo $venvs | cut -d' ' -f1`
    venv1=`echo $venvs | cut -d' ' -f2`
    if [[ $venv0 == "*" ]]; then
      venv_name=$venv1
    else
      venv_name=`echo $venvs| awk '{ print $1 }'`
    fi

    mode=local
    if [[ $1 == "--global" ]]; then
      mode=global
    fi
    echo "Set ${mode}　Python version to ${venv_name}"
    pyenv $mode $venv_name
}

$ venv # pyenv local
$ venv --global #pyenv global

Convenient
