`conda` env vars

# `conda` env vars 

## Quick `gist` to setup `conda` env variables

I try to keep `virtualenv` and `conda` going to ensure I stay versed in both virtual environment
methodologies.  In `virtualenv` I can simply moding the script located in `$PATH/bin/activate` where
`$PATH` is the path to the virtual environment I'm working on.  However, the process in `conda` is a 
little more involved (but also straightforward, as all things `conda` seem to be).

## Create `activate / deactivate` directories

If `$PATH` is the directory for the conda environment, let's use for example, `my_env`.  So:

	$ echo $PATH
	/home/benjaminmgross/anaconda/envs/my_env/

I would now want to follow the guidance provided on [this stackoverflow post](http://stackoverflow.com/questions/31598963/how-to-set-specific-environment-variables-when-activating-conda-environment), where we need to create the two following directories:

	$ cd PATH
	$ mkdir -p ./etc/conda/activate.d
	$ mkdir -p ./etc/conda/deactivate.d

## Create the `env_vars.sh` files

    $ touch ./etc/conda/activate.d/env_vars.sh
    $ touch ./etc/conda/deactivate/env_vars.sh

## Populate the files

    ./etc/conda/activate/env_vars.sh

    #!/bin/sh

    export MY_KEY='secret-key-value'
    export MY_FILE=/path/to/my/file/

    ./etc/conda/deactivate/env_vars.sh

    #!/bin/sh

    unset MY_KEY
    unset MY_FILE
