 1 | ## install:
 2 | 
 3 | 0-) You need to have **virtualenvwrapper** installed
 4 | 
 5 | 1-) first install **pyenv**:
 6 | 
 7 |     git clone git://github.com/yyuu/pyenv.git ~/.pyenv
 8 |     
 9 | 2-) then just: 
10 | 
11 |     git clone git://github.com/andersoncardoso/pyenv-autoenv.git ~/.pyenv/plugins/pyenv-autoenv
12 |     
13 | 3-) add these lines to your .bashrc or .zshrc:
14 | 
15 |     if [[ -d $HOME/.pyenv ]];then
16 |         export PATH="$HOME/.pyenv/bin:$PATH"
17 |         eval "$(pyenv init -)"
18 |         source ~/.pyenv/plugins/pyenv-autoenv/bin/pyenv-autoenv
19 |     fi
20 |     
21 | ## How it works:
22 | 
23 | Pyenv already has a behavior where: whenever you enter a directory with a `.python-version` file set 
24 | with a version number in, he autoloads that python version. 
25 | 
26 | I've extended this behavior to work with virtualenvwrapper. So whenever you enter a dir with a `.python-env` 
27 | set with a virtualenv name, he activates that environment automatically. 
28 | 
29 | Another aditional behavior is: If you don't have the python version from `.python-version` installed, 
30 | he automatically installs it for you. And if you dont have the virtualenv from `.python-env` created, 
31 | he creates and load it for you.
32 | TODO: make this optional
33 | 
34 | Example: if you have a project on git with a `.python-version` with `2.7.5` in it, and a  `.python-env` with `my_env`. 
35 | When you clone it, all need to do is `cd` into the project's directory and it will load (and install if needed) both 
36 | the python-2.7.5 and the my_env virtualenv (*uses virtualenvwrapper* so you need to have it installed).
