# SIFTTTER 1.5: An IFTTT-to-Day One Logger by Craig Eley 2014 <http://craigeley.com>
# Based on tp-dailylog.rb by Brett Terpstra 2012 <http://brettterpstra.com>
# Multiple Date Function by Paul Hayes 2014 <http://paulrhayes.com>
#
# Notes:
# * Uses `mdfind` to locate a specific folder of IFTTT-generated text files changed in the last day
# * The location of your folder should be hardcoded in line 67, and the location of your Day One in line 66
# * Scans leading timestamps in each line matching the selected dates
# * Does not alter text files in any way
# * Changes ampersand ('&') to 'and' so the script keeps running
# * Does not require the Day One CLI tool
# * Only generates report if there are completed tasks found
# * Compiles each day into a single Day One entry
# * It's configured to locate a Dropbox-synced journal, so
# * If you use iCloud you'll can just uncomment lines 64 and 65, and comment line 66
# * To set the Day One entries to starred, just change false to true on line 24
