Anki Kunren (暗記 訓練)

Anki Kunren is a program to drill japanese kanji stroke order and practice writing in sync with an Anki study session.

Installation

1. install via pip: pip install anki-kunren
2. install anki-connect with code 2055492159

Usage

Open Anki and begin a review. You can then use kunren as follows:

usage: kunren [-h] [-s S] [-d D] [--field FIELD] [--size SIZE]

optional arguments:

• -h, --help Show help message
• -s S Start point size in px. defaults to 5px
• -d D Stroke forgiveness in average px from actual. defaults to 25px
• --field FIELD name of anki card field containing kanji. defaults to "Vocabulary-Kanji"
• --size SIZE Length of a size of the square canvas in pixels. Defaults to 300.

While running, you can use the following controls:

• h: hint the current stroke
• a: animate the current stroke
• n: next kanji in the expression
• esc: quit
• c: refresh the current card shown. This is done automatically when all characters have been drawn, but would slow the program to a crawl if checked for every frame.

Notes

• When the size parameter is changed, all tolerances get multiplied by the ratio of size/109.

TODO

• catch all indexoutofbounds
• smoother kanji lines
• different coloring for different parts of stroke based on how wrong it is.
