lins05 / mn3_anki_fix

This tools may no longer work with the latest version of MarginNote.

This tool was written several years ago, and most likely the format of the apkg file exported by MN has been changed so far.

What is this

Fix the anki cards exported by MarginNote3 (up to 3.4.3). The problems I suffer are:

• Only one anki card is generated, even if there are multiple clozes.
• Inconsistent & confusing format of the card front / back for cards w/ clozes in the title and cards w/o.
• MN tags appear in the back of the anki card.

This script reads the contents of generated apkg file, and makes use of genanki package to rewrite it to a better one.

Visual Comparison

Original apkg imported into Anki

• title shown in bottom
• only one card for 3 clozes
• tag is shown in the back card

Improved apkg imported into Anki

Limitations

1. All existing MN3 anki cards must be deleted from anki first. Otherwise the import would fail.
2. Cards with images/videos/audios are not supported.

How to use

1. Make sure python3 is installed on your Mac.
2. Install the requirements

    pip3 install -r requirements.txt

3. Run the script to fix the exported apkg file before importing them to anki.

./fix_mn_anki_exports.py fix /path/to/apkg

You'll see output like this:

[09/14/2019 23:00:47][fix_mn_anki_exports]: Auto located apkg file /path/to/apkg
[09/14/2019 23:00:47][fix_mn_anki_exports]: files: ['collection.anki2', 'media']

[09/14/2019 23:00:47][fix_mn_anki_exports]: Generating output file /tmp/output.apkg

The improved apkg would be /tmp/output.apkg.

mn3_anki_fix's Issues

Stuck at step 3

Dear, Lins05.

Thank you very much for this script. I'm stuck at step 3 :

3. Run the script to fix the exported apkg file before importing them to anki.
   ./fix_mn_anki_exports.py fix /path/to/apkg

I managed to install and run python but I don't know the process to run the script and/or indicate the correct path to Apkg.

Here is what I did :

1. Installed Python, when I run $ python3
   I got :

Python 3.10.0 (v3.10.0:b494f5935c, Oct  4 2021, 14:59:20) [Clang 12.0.5 (clang-1205.0.22.11)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>

2. Exported my flashcards from MN to this path :
   /Users/josephdupont/Desktop/Droit public.apkg

3. So now I'm stuck. Here is what I get when I run the script ./fix_mn_anki_exports.py fix /path/to/apkg (after running python3 in terminal) :

>>> ./fix_mn_anki_exports.py fix /Users/josephdupont/Desktop/Droit public.apkg
  File "<stdin>", line 1
    ./fix_mn_anki_exports.py fix /Users/josephdupont/Desktop/Droit public.apkg
    ^
SyntaxError: invalid syntax
>>> 

May I ask you to please help me (and save my exams at the same time ?..)

Thank you very much for your hard work fixing MN issues.
Best regards,
Joseph

【Solved】Can't work when decks include Chinese

It's an amazing script. But I meet a big problem, when my decks include Chinese words. It doesn't work.

OS: Windows 10
Python 3.8.1

Here are how I found:

"1.apkg" does not contain Chinese and "2.apkg" contains.

Output on cmd:
