Anki Japanese Text Cleaner

This is a plugin for Anki that can help clean up Japanese text in the following ways:

Clean unnecessary spaces, while preserving those spaces that are necessary for indicating the start of a Japanese reading (as in the Japanese Support plugin).

<b> 一[いち]</b>から 始[はじ]めましょう。
=>
<b>一[いち]</b>から 始[はじ]めましょう。

彼女[かのじょ]はイタリア 語[ご]が<b> できます</b>。
=>
彼女[かのじょ]はイタリア 語[ご]が<b>できます</b>。

Clean unnecessary furigana from the beginning, end, or within individual readings within text.

別に[べつに]
=>
別[べつ]に

世の中[よのなか]
=>
世[よ]の 中[なか]

Both are designed to:

• Properly handle text with multiples lines
• Properly handle text with HTML markup by allowing HTML tags to pass through unchanged

In addition, there are some features to guard against accidental changes or bugs in the plugin:

• A Check action logs all changes that would be made without taking any action.
• A Diff action produces a colorful HTML diff highlighting in green what will been added and in red what will be removed for each note.
• A 'Fix' action actually performs the changes.
• Each batch of changes is recorded in the undo history within Anki.
• A full change log is kept in a SQLite database within the plugin's local directory. Recent changes can be viewed in the UI and the full history of changes can be exported to a CSV file. This enables you to recover any previous values altered by the plugin.

Despite these safety features, it's a good idea to back up or export your collection before using this plugin just to be safe.

You can access the dialogs by clicking Browse to open the card browser and then clicking Edit -> Japanese Text Cleaner. The fixer dialgos require you to select some cards first. These are the cards that will be checked.

Testing

I have tested against the following shared decks which I found on Anki's Japanese shared decks page. Below I include some stats as of July 10, 2019 when I lasted tested the plugin against the decks.

Deck	Notes	Field	Spacing Fixes	Furigana Fixes
Japanese Core 2000 2k - Sorted w/ Audio	2007	Reading	266	1
Japanese Visual Novel, Anime, Manga, LN Vocab - V2K	1988	Reading	4	55

To get a better idea about how the plugin works, I've included some examples from each deck.
