# Boa Constructor installation script for OS X / macOS
#
# This script tries to automate the installation of Boa Constructor
# https://bitbucket.org/cwt/boa-constructor on macOS.
#
# Tested on macOS Sierra / 10.12.6 / Darwin 16.7.0
#
# Requirements:
# - Python 2.7 from Homebrew (macOS's native python won't obey our DYLD_LIBRARY_PATH properly)
# - virtualenv command
#
# Based on:
# - https://wiki.wxpython.org/wxPythonVirtualenvOnMac
# - https://bitbucket.org/cwt/boa-constructor/issues/3/cant-create-project-on-mac

######################################################################
# Configuration parameters
# Set the path to your Brew python 2.7 binary:
#PYTHON_CMD=/usr/local/opt/home-brew/bin/python2.7
PYTHON_CMD=/usr/local/bin/python2.7

# Set your desired Boa installation path:
BOA_DIR=~/boa
