pyenv + pyenv-Automatically load the virtualenv environment in the virtualenv environment

Thing you want to do

For those who use python in the pyenv + pyenv-virtualenv environment. I want to automatically load .python-version and ʻactivate` when I move the directory.

Reason,

cd ~/foo pyenv activate foo

cd ~ pyenv deactivate

Because it is troublesome to activate and deactivate one by one.

If you are using direnv, use ʻeval" $ (direnv hook bash) " If it is described as follows in~ / .bashrc etc., every time you cd It seems that it hooks me, so I should be able to do it without usingdirenv. It was easy to do after a little research, so I posted it after a long time as a reminder (Maybe I should use direnv`, but I personally didn't get used to it)

correction: eval "$(pyenv virtualenv-init -)" And, if it is described in ~ / .bash_profile, it will switch automatically ... I intended to have described it above, but there was a case where the environment did not switch because the description position was wrong ...

Setting

It is assumed that the pyenv and pyenv-virtualenv environments have been set. Then add the following to .bash_profile etc. to .bash_profile etc.

cd(){
    now_path=`pwd`
    now_pyenv_filepath=$now_path/.python-version
    if [ -e ${now_pyenv_filepath} ];then
        now_pyenv=`cat ${now_pyenv_filepath}`
        pyenv deactivate
    fi

    new_pyenv_filepath=$1/.python-version

    if [ -e ${new_pyenv_filepath} ];then
        local_env=`cat ${new_pyenv_filepath}`
        pyenv activate ${local_env}
    fi

    builtin cd "$1"
}

If you write the above and reload it as source .bash_profile It will automatically deactivate and ʻactivate`.

First read the current location with pwd If there is .python-version there, the first half is deactivate

Furthermore, if there is .python-version in the destination folder Load it ʻactivate and finally load the built-in cd` I'm moving.

I couldn't call the built-in command with bulitin hoge.

reference

I referred to the following that I went through with shell hook.
