# ExportCardsAsText.py
# Anki addon for exporting cards from Anki to a text file (CSV, XML, JSON).
# Copyright (c) 2014 Jiri Kriz, http://www.nosco.ch/main/en/contact.php
# License: GNU GPL, version 3 or later; http://www.gnu.org/copyleft/gpl.html

# Version 1.1, 14-Sep-2014
# Support: None. Use at your own risk. You can send me suggestions and bug reports. 

# ======================================================
# Remarks:

# It is assumed that the created card and the associated reversed card (if any)
# have neighbouring IDs. More precisely, if a card has ID1 and its 
# associated reversed card has ID2, then no other card has an ID between ID1 and ID2.
# It seems that this assumption is always fulfilled.
# If this assumption were wrong then reverse cards
# would potentially also be exported even if ExportSettings.REVERSE_CARDS = False.
# Note that associated reverse cards have the same 'NoteID' and different 'CardType'.

# The addon was tested on Windows only.

# ======================================================
# Versions:
# 1.0 (19-May-2014) Initial version
# 1.1 (14-Sep-2014) Fixed bug 'IndexError' in deck list
