envdir not working with pyenv + virtualenvs properly? daemontools behaves correctly

hi @jezdez, it seems envdir is modifying the PATH in some unexpected way when using virtualenv. daemontools seems to be working as expected.

I have a pretty vanilla set up using pyenv and virtualenvwrapper. Nothing fancy.

setup:

$ deactivate
$ mkvirtualenv test
$ deactivate

with jezdez/envdir:

$ workon test
$ which python
/Users/johria/.virtualenvs/test/bin/python
$ envdir envs/prod which python
/Users/johria/.pyenv/versions/3.6.1/bin/python

^^^^ error is here ^^^^

uninstall jezdez/envdir, install daemontools:

$ deactivate
$ pip uninstall envdir
$ brew install daemontools

with daemontools:

$ workon test
$ which python
/Users/johria/.virtualenvs/test/bin/python
$ /usr/local/bin/envdir envs/prod which python
/Users/johria/.virtualenvs/test/bin/python

This only occurs with pyenv. With homebrew python:

$ echo "$PATH"
bin:/usr/local/sbin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

$ python -c "import os; print(os.environ['PATH'])"
bin:/usr/local/sbin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

No changes to the PATH. The pyenv wrapper shim is doing the addition to the PATH!

SO. In conclusion, when envdir is installed globally via pyenv, the pyenv shim is injecting variables on to the PATH. When inside a virtualenv, the shimmed envdir ends up changing the PATH so its no longer using the virtualenv but instead its using the global python.

Workaround: Install envdir using homebrew python or inside of your virtualenv. Do not install envdir via pyenv because it will change the PATH.

@hangtwenty Just a quick side offtopic note, I am using the following shell function to export envdirs (zsh):

envdir-export () {
	setopt extendedglob
	local envdir=$1 
	if ! [ -d "$envdir" ]
	then
		echo "$envdir is not a dir."
		return 1
	fi
	for i in $envdir/*(.)
	do
		if [[ "${i:t}" == *.* ]]
		then
			continue
		fi
		echo "Exporting $i:t"
		eval "export ${i:t}='$(<$i)'"
	done
}

I call this for example via autoenv (https://github.com/Tarrasch/zsh-autoenv) for projects, or manually on certain dirs to get extra parts of some config.
