Dynamic UI lists in Indigo 6

Indigo 6 is a popular home automation controller software package on the Mac. Extensibility is one of its main features and it allows users to add a range of features to suit their needs.

Using Python scripting, users can create plugins that provide extended functionality. These plugins can provide a custom configuration UI to the user. Since the documentation around a particular feature - dynamic lists was lacking, I’ve written up my approach here.

Import and tag with Hazel and DEVONthink Pro Office

Hazel and DEVONthink make a great pair as I’ve written before. Using AppleScript, it’s possible to take the import workflow even further by tagging incoming files automatically.

Use case

I download a lot of mp3 files containing pronunciation of words in a language I’ve been learning. I keep a record of these words and tag them appropriately using my hierarchical tagging system.

I’d like to download the files to a directory on the desktop. Keep them there for a few minutes until I’m done working with them, then import the file to DEVONthink Pro Office, tag the file there and delete the original.

Read on to see how the Hazel rule is written, including the AppleScript to make it happen.

Hazel rule

The Hazel rule is simple:

  • Look in a directory called “mp3”.
  • Select files that have the mp3 extension.
  • Allow the file to remain in place for 5 minutes
  • Thereafter, execute the import and tagging script.
  • Finally, delete the original file

Most of the action is in the AppleScript that provides a bridge from Hazel to DEVONthink.

AppleScript import action

Hazel exposes a variable theFile that we can use as we import and tag the file. Here’s the entire AppleScript with comments following.

tell application id "com.devon-technologies.thinkpro2"
    launch
    open database "/Users/alanduncan/Documents/russian.dtBase2"
    set dbID to 7
    set theDatabase to get database with id dbID
    tell theDatabase
        set destGroup to first item of (records whose name is "reference")
        set theRecord to import theFile to destGroup
        tell theRecord
            set {od, AppleScript's text item delimiters} ¬
			   to {AppleScript's text item delimiters, ","}
            set tags to text items of "source_web, type_sound"
            set AppleScript's text item delimiters to od
        end tell
    end tell
end tell

Line 2-3 - Launch DEVONthink and open the receiving database. Line 4-5 - Reference the database by ID. There are other ways to do this. I just happened to find the ID in Script Debugger so I used it. Line 7 - Set a reference to the destination group. Mine is reference. Line 8 - Perform the import returning the imported record. You can import without the return but then you would have to do extra work to find the file you want to tag. Line 10 - Allow us to use a comma-delimited list of tags Line 12 - Set the incoming file’s tags. Mine are as listed; yours would be something else. Line 13 Restore the original text delimiters

That’s it! No you have a mechanism for automatically managing files from the Finder to DEVONthink.

Using AppleScript with MailTags

I’m a fan of using metadata to classify and file things rather than declarative systems of nested folders. Most of the documents and data that I store for personal use are in DEVONthink which has robust support for metadata. On the email side, there’s MailTags which lets you apply metadata to emails. Since MailTags also supports AppleScript, I began to wonder whether it might be possible to script workflows around email processing. Indeed it is, once you discover the trick of what dictionary to use.

Using AdBlock Plus to block YouTube comments

Web

YouTube comments are some of the most offensive on the web. Even serious videos attract trolls bent on inscribing their offensiveness and cruelness on the web.

Here’s one method of dealing with YouTube comments. Treat the comments block as an advertisement and block it.^[There are other ways of avoiding YouTube comments. I’ve used ViewPure but it’s hard to find content that way even though they seem to be working on making it more seamless to get from YouTube to ViewPure.]

Introducing AnkiStats & AnkiStatsServer

The spaced repetition software system Anki is the de facto standard for foreign language vocabulary learning. Its algorithm requires lots of performance data to schedule flashcards in the most efficient way. Anki displays these statistics in a group of thorough and informative statistical graphs and descriptive text.

However, they aren’t easily available for the end-user to export. Thus, the reason behind the companion projects AnkiStats and AnkiStatsServer.

The premise is that you can run your own more extensive experiments and statistical tests on the data once you have it in hand. A bit of technical expertise is needed to get it operational but if you are up to it, clone the github repos above and go for it.

Waking the computer to allow AppleScript to run

I have a number of AppleScript applications that need to run at odd times. These maintenance tasks often attempt to run while the computer is sleeping. Particularly those that rely on UI scripting do not function during this period.

This most flexible way of dealing with this is to manipulate the power management settings directly via the pmset(1) command.

The variety of options available using pmset is staggering and beyond the scope of this post. Here’s what I do to wake the computer up at specific times so that scheduled AppleScripts can run:

An easier way to automate synchronization of Anki profiles with AppleScript

After waking up this morning with my mouse locked onto the Anki icon in the dock and trying to figure out how to get Activity Monitor up and running so I could force quite my Automator application that I described yesterday I figured it was back-to-the-drawing board.

I’d like to have used the Accessibility Inspector to manipulate the PyQt objects in Anki’s windows, they aren’t exposed in a may that you can script them. But System Events rules all.

Scheduling synchronization of Anki databases on OS X

While working on a project to automatically collect statistics on my Anki databases (stay tuned…) I worked out a system for scheduling synchronization from my desktop OS X machine.

Prerequisites

  • LaunchControl is a GUI application that lets you create and manage user services on OS X
  • Anki is a spaced repetition memorization software system

The solution relies on Automator. Normally, I don’t care much for Automator. It has too many limits on what tasks I can accomplish and workflows created with it are often fragile. However, in this case, we take advantage of its workflow recording feature. We’re going to record the process of opening Anki, selecting the profile to sync, then quitting Anki. This sequence of events ensures that the database on the local system is synchronized with the remote version.

Resizing of images for Anki with Hazel and ImageMagick

I use Anki to study foreign language vocabulary. It’s the de facto spaced repetition software for memorization.^[Yes, I’m aware that others exist. I’ve tried many but always have come back to Anki.] When making flashcards for language learnings, I try to use imagery as much as possible. So a card may have a Russian word on one side and just an image on the opposite side. (Since I already know the English word that the image represents, why not try to engage a different part of the brain to help with memorization?)

Writing Hexo filters

Hexo, the static blogging system that I use is very extensible and provides numerous hooks into generation pipeline.

While working on a Russian language blog that’s coming online soon, I had the opportunity to write a filter to render Cyrillic text in a different font than the rest of the body text.

Markup filter use case

I wanted to set the Cyrillic text apart both in color, typeface, and font weight. Although I could have extended Hexo using a new tag, I decided to use a filter so that after rendering HTML anywhere on the blog, items demarcated by double pipes || would be replaced by a new <span>.
