BiDi Tools For Anki
An add-on for Anki that adds some editor tools for bidirectional text (BiDi)—text containing different types of alphabets that have different directionalities (e.g. mixed English and Arabic text).
Anki already provides an option to set each field's direction under the Fields screen, and modern systems do a decent job handling mixed text thanks to the Unicode Bidirectional Algorithm, but there are cases when it's necessary to explicitly specify the direction of certain parts of the field text because of limitations in what the algorithm can do automatically.
BiDi Intro
You can read some incomplete notes I've written about the BiDi algorithm in technical.md
Usage
The add-on provides buttons to set the direction of the selected text to either LTR (left to right, like the Latin script and most scripts), or RTL (right to left, like in Arabic, Hebrew, Persian, etc.)
The following actions are available in the editor:
- Left-To-Right: Apply left-to-right direction to the HTML block element surrounding the selected text (if any). If you're not familiar with HTML, you can think of this as roughly setting the direction of the entire line where the cursor is currently at.
- Right-To-Left: Ditto, but for RTL.
- More options under the third icon:
- LTR Selected: Apply left-to-right to direction to the selected text only.
- RTL Selected: Ditto, but for RTL.
- Insert Characters: A menu for inserting common Unicode characters used to affect text directionality. You probably don't need to use any of these as the previous options should cover most cases, but see https://en.wikipedia.org/wiki/Bidirectional_text#Unicode_bidi_support for an explanation of the characters.

Translations
The add-on is localized to English and Arabic. You can help translate the add-on to your langauge and send me the translated strings and I will include them (or you can open a PR if you're technical). There are only a few strings to translate. See i18n.py for a list of the strings and how they are defined for each language.
