Converting Cyrillic UTF-8 text encoded as Latin-1

This may be obvious to some, but visually-recognizing character encoding at a glance is not always obvious. For example, pronunciation files downloaded form Forvo have the following appearance: pronunciation_ru_оÑ‚бывание.mp3 How can we extact the actual word from this gibberish? Optimally, the filename should reflect that actual word uttered in the pronunciation file, after all. Step 1 - Extracting the interesting bits The gibberish begins after the pronunciation_ru_ and ends before the file extension.

accentchar: a command-line utility to apply Russian stress marks

I’ve written a lot about applying and removing syllabic stress marks in Russian text because I use it a lot when making Anki cards. This iteration is a command line tool for applying the stress mark at a particular character index. The advantage of these little shell tools is that they can be composable, integrating into different tools as the need arises. #!/usr/local/bin/zsh while getopts i:w: flag do case "${flag}" in i) index=${OPTARG};; w) word=${OPTARG};; esac done if [ $word ]; then temp=$word else read temp fi outword="" for (( i=0; i<${#temp}; i++ )); do thischar="${temp:$i:1}" if [ $i -eq $index ]; then thischar=$(echo $thischar | perl -C -pe 's/(.

sterilize-ng: a command-line URL sterilizer

Introducing sterilize-ng [GitHub link] - a URL sterilizer made to work flexibily on the command line. Background The surveillance capitalist economy is built on the relentless tracking of users. Imagine going about town running errands but everywhere you go, someone is quietly following you. When you pop into the grocery, they examine your receipt. They look into the bags to see what you bought. Then they hop in the car with you and keep careful records of where you go, how fast you drive, whom you talk with on the phone.

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:

Stripping Russian stress marks from text from the command line

Russian text intended for learners sometimes contains marks that indicate the syllabic stress. It is usually rendered as a vowel + a combining diacritical mark, typically the combining acute accent \u301. Here are a couple ways of stripping these marks on the command line: First is a version using Perl #!/bin/bash f='покупа́ешья́'; echo $f | perl -C -pe 's/\x{301}//g;' And then another using the sd tool: #!/bin/bash f='покупа́ешья́'; echo $f | sd "\u0301" "" Both rely on finding the combining diacritical mark and removing it with regex.

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:

Normalizing spelling in Russian words containing the letter ё

The Russian letters ё and e have a complex and troubled relationship. The two letters are pronounced differently, but usually appear the same in written text. This presents complications for Russian learners and for text-to-speech systems. In several recent projects, I have needed to normalize the spelling of Russian words. For examples, if I have the written word определенно , is the word actually определенно ? Or is it определённо ?

Scraping Russian word definitions from Wikitionary: utility for Anki

While my Russian Anki deck contains around 27,000 cards, I’m always making more. (There are a lot words in the Russian language!) Over the years, I’ve become more and more efficient with card production but one of the missing pieces was finding a code-readable source of word definitions. There’s no shortage of dictionary sites, but scraping data from any site is complicated by the ways in which front-end developers spread the semantic content across multiple HTML tags arranged in deep and cryptic hierarchies.

Encoding of the Cyrillic letter й - a UTF-8 gotcha

In the process of writing and maintaining a service that checks Russian word frequencies, I noticed peculiar phenomenon: certain words could not be located in a sqlite database that I knew actually contained them. For example, a query for the word - английский consistently failed, whereas other words would succeed. Eventually the commonality between the failures became obvious. All of the failures contained the letter й , which led me down a rabbit hole of character encoding and this specific case where it can go astray.

Dynamic DNS - auto-updating from macOS

To run a little project (that I’ll describe at some point in the future) I have to run a small web server from my home computer, one that happens to run macOS. More than anything else, this is just a reply of what I did to get it running in case: a) I have to do it again, or b) Someone else can find it useful. Sign up for dynamic DNS service I signed up for service with dynv6 because I saw it recommended elsewhere and it didn’t look creepy like some of the other options.
