Using Perl in Keyboard Maestro macros

One of the things that I love about Keyboard Maestro is the ability to chain together disparate technologies to achieve some automation goal on macOS.

In most of my previous posts about Keyboard Maestro macros, I’ve used Python or shell scripts, but I decided to draw on some decades-old experience with Perl to do a little text processing for a specific need.

Background

I want this text from Wiktionary:

to look like this:

Splitting a string on the command line - the search for the one-liner

It seems like the command line is one of those places where you can accomplish crazy efficient things with one-liners.

Here’s a perfect use case for a CLI one-liner:

In Anki, I often add lists of synonyms and antonyms to my vocabulary cards, but I like them formatted as a bulleted list. My usual route to that involves Markdown. But how to convert this:

известный, точный, определённый, достоверный

to

- `известный`
- `точный`
- `определённый`
- `достоверный`

After trying to come up with a single text replacement strategy to make this work, the best I could do was this:

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. For example, a cloze deletion note type with the following content requires the learner to supply the missing word:

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 2.1.41 does not.
  • After Auto Markdown stopped working, I installed the supposed fix Auto Markdown - fix version but that didn’t work either.
  • It’s possible that the Mini Format Pack will work, but honestly I’m tired of the constant break-fix-break-fix cycle with Anki.

The problem

The real problem with Markdown add-ons for Anki is the same as every other add-on. They are all hanging by a thread. Almost every minor point upgrade of Anki breaks at least one of my add-ons. It’s nearly impossible to determine in advance whether an Anki upgrade is going to break some key functionality that I rely on. And add-on developers, even prominent and prolific ones come and go when they get busy, distracted or disinterested. It’s one of the most frustrating parts of using Anki.

W3schools.com has a CSS library that’s quite nice. I often use Bootstrap; but I like some of the visual features here better. For example, I like their tags because they have more flexible use of colour.


If you want to fetch from a Python dictionary, but you need a default value, this is how you do it:

upos_badge = {'noun': 'lime','verb': 'amber', 'adv': 'blue',}
badge_class_postfix = upos_badge.get(value.lower(), 'light-grey')

I recently learned about DeepL as an alternative to Google Translate. It seems really good.

Undoing the Anki new card custom study limit

Recently I hit an extra digit when setting up a custom new card session and was stuck with hundreds of new cards to review. Desparate to fix this, I started poking around the Anki collection SQLite database, I found the collection data responsible for the extra cards. In the col table, find the newToday key and you’ll find the extra card count expressed as a negative integer. Just change that to zero and you’ll be good.

Escaping "Anki hell" by direct manipulation of the Anki sqlite3 database

There’s a phenomenon that verteran Anki users are familiar with - the so-called “Anki hell” or “ease hell.”

Origins of ease hell

The descent into ease hell has to do with the way Anki handles correct and incorrect answers when it presents cards for review. Ease is a numerical score associated with every card in the database and represents a valuation of the difficulty of the card. By default, when cards graduate from the learning phase, an ease of 250% is applied to the card. If you continue to get the card correct, then the ease remains at 250% in perpetuity. As you see the card at its increasing intervals, the ease will remain the same. All good. Sort of.

A comprehensive system for generating chorus repetition source material from Glossika sentence tracks

Generate iterated tracks at normal, 75% and 50% speeds

In previous posts I described a group of Audacity macros that create iterated tracks for chorus repetition practice. As Dr. Kjellin described we use Audacity to create a total of six repetitions per track.

Automating the generation of tracks with AppleScript

On macOS, AppleScript is the core technology used to automate routine tasks. In this case, we make extensive use of UI scripting since Audacity is not a scriptable application.

More chorus repetition macros for Audacity

In a previous post I described macros to support certain tasks in generating source material for L2 chorus repetition practice. Today, I’ll describe two other macros that automate this practice by slowing the playback speed of the repetition.

Background

I’ve described the rationale for chorus repetition practice in previous posts. The technique I describe here is to slow the sentence playback speed to give the learner time to build speed by practicing slower repetitions. By applying the Change Tempo... effect^[Change tempo effect in the Audacity manual] in Audacity. In my own practice, I will often begin complex Russian sentences at -50% speed and progress to -25% speed before practicing the pronunciation at native-level speed. By practicing at slow speeds, it gives the learner time to appreciate how syllables are connected to each other. The prosody is more apparent.
