Dynamically loading Javascript in Anki card templates

The ability to execute Javascript in Anki card templates offers users flexibility in displaying data. In Anki 2.1, though, the asynchronous execution of Javascript means that user script functionality is not entirely predictable. This post on r/Anki discusses an approach for dynamically loading Javascript resources and ensuring that they are available when the card is displayed. Since I modularize my Javascript code so that it can be flexibly deployed to different card types, I extended this method to allow the template developer to load multiple scripts in one <script> block.

Extending the Anki Cloze Anything script for language learners

It’s possible to use cloze deletion cards within standard Anki note types using the Anki Cloze Anything setup. But additional scripts are required to allow it to function seamlessly in a typical language-learning environment. I’ll show you how to flexibly display a sentence with or without Anki Cloze Anything markup and also not break AwesomeTTS. Anki’s built-in cloze deletion system The built-in cloze deletion feature in Anki is an excellent way for language learners to actively test their recall.

Complete fix for broken Knowclip .apkg files

I think this is the last word on fixing Knowclip .apkg files. I’ve developed this in bits and pieces; but hopefully this is the last word on the subject. See my previous articles, here and here, for the details. This issue, again, is that Knowclip gives these notes and cards sequential id values starting at 1. But Anki uses the and the as the creation date. I logged it as an issue on Github, but as of 2021-04-15 no action has been taken.

Fixing Knowclip .apkg files: one more thing

(N.B. A much-improved version of this script is published in a later post) Fixing the Knowclip note files as I described previously, it turns out, is only half of the fix with the broken .apkg files. You also need to fix the cards table. Why? Same reason. The rows are number sequentially from 1. But since Anki uses the card id field as the date added, the added field is always wrong.

Fixing Knowclip Anki apkg creation dates

(N.B. A much-improved version of this script is published in a later post) Language learners who want to develop their listening comprehension skills often turn to YouTube for videos that feature native language content. Often these videos have subtitles in the original language. A handful of applications allow users to take these videos along with their subtitles and chop them up into sentence-length bites that are suitable for Anki cards. Once such application is Knowclip.

Generating HTML from Markdown in Anki fields

I write in Markdown because it’s much easier to keep the flow of writing going without taking my hands off the keyboard. I also like to write content in Anki cards in Markdown. Over the years there have been various ways in of supporting this through add-ons: The venerable Power Format Pack was great but no longer supports Anki 2.1, so it became useless. Auto Markdown worked for a while but as of Anki version 2.

Pre-processing Russian text for the AwesomeTTS add-on in Anki

The Anki add-on AwesomeTTS has been a vital tool for language learners using the Anki application on the desktop. It allows you to have elements of the card read aloud using text-to-speech capabilities. The new developer of the add-on has added a number of voice options, including the Microsoft Azure voices. The neural voices for Russian are quite good. But they have one major issue, syllabic stress marks that are sometimes seen in text intended for language learners cause the Microsoft Azure voices to grossly mispronounce the word.

Factor analysis of failed language cards in Anki

After developing a rudimentary approach to detecting resistant language learning cards in Anki, I began teasing out individual factors. Once I was able to adjust the number of lapses for the age of the card, I could examine the effect of different factors on the difficulty score that I described previously. Findings Some of the interesting findings from this analysis: Prompt-answer direction - 62% of lapses were in the Russian → English (recognition) direction.

Refactoring Anki language cards

Regardless of how closely you adhere to the 20 rules for formating knowledge, there are cards that seem destined to leechdom. For me part of the problem is that with languages, straight-up vocabulary cards take words out of the rich context in which they exist in the wild. With my maturing collection of Russian decks, I recently started to go through these resistant cards and figure out why they are so difficult.

Directly setting an Anki card's interval in the sqlite3 database

It’s always best to let Anki set intervals according to its view of your performance on testing. That said, there are times when directly altering the interval makes sense. For example, to build out a complete representation of the entire Russian National Corpus, I’m forced to enter vocabulary terms that should be obvious to even elementary Russian learners but which aren’t yet in my nearly 24,000 card database. Therefore, I’m entering these cards gradually.
