#!/bin/bash

# This script 
#  - clones the libigl github repo into a temporary directory
#  - updates submodules
#  - compiles static library
#  - compiles tutorial
# If any steps fail then an email is sent to a list of recipients (add yourself
# if you'd like to be alerted to failures, see below regarding spam filters).
#
# You can set up an automated nightly build-check at 2:30 AM using:
#
#     crontab -e
#
# and then add the line:
#
#     30 2 * * * source /Users/ajx/.profile; /usr/local/igl/libigl/scripts/clone-and-build.sh
#
# replace the path above with the **full path** to this file.

# Report that a command has failed and list its output
#
#     report_error command output
#
# Note: Most mail clients will mark these messages as spam even if the local
# sender (e.g. ajx@luftmatratze.local) is in your contact list. To force these
# message to be not marked as spam, create a filter.
#
# You can test your spam settings with
#
# echo "t3st 3mail" | mail -s "libigl test email" youremail@gmail.com
#
# This will almost certainly end up in your spam, but you can find your default
# email address as the sender and add a filter.
