# Restore simplenote backup
#
# If you want to restore your Simplenote for Mac database, you can use this script.
# I created it for this issue:
# http://help.simplenote.com/customer/en/portal/questions/2773965-most-of-my-notes-were-deleted?new=2773965
#
# First, find a good backup of your simplenote database stored in
# ~/Library/Containers/com.automattic.SimplenoteMac/Data/Library/Simplenote/Simplenote.storedata
#
# In simplenote, manually delete all your notes (cmd+a, delete)
#
# Then run this script:
# $ cat path_to_simplenote.storedata | ruby simplenote_restore.rb
#
# ...and that's it.
# NB: this script doesn't restore tags, modification times, or anything but the content.
# That's all I cared about.
