# Hello! This file isn't necessary to look at. All you need to know
# is that:
# 
# 1. You can create Python files on the left "New File" and use 
#    `numpy` or `opencv-python` freely.
# 2. On the bottom left, click on "Tools > Terminal" to open terminal
#    and run `python <script>` just as you would normally on your 
#    own computer.
#
# I've included explanations of what's going on, below, in case
# you're really *that curious!

# Install all packages to the /tmp directory, to avoid counting
# temporary files, like pip-installed packages, towards your 
# 200 MB limit for glitch projects.
pip3.7 install --no-cache-dir --prefix=/tmp opencv-python

# Point your python path to your unconventional installation path.
export PYTHONPATH=/tmp/lib/python3.7/site-packages

# Alias python (by default python2.7) to the latest Python available
# on Glitch as of time of writing. Also `refresh` (a custom Glitch
# command for refreshing the editor and file browser with disk
# contents), so that you can see any files you may write to disk.
function python() {
  python3.7 $@ && refresh;
