I work on quite a few git repositories at once, and I don’t always commit changes in one before making changes to another. Or if I do, I don’t always push the changes up straight away. That might not be best practice in software development, but hey, it’s what I do. The issue for me is remembering what state each repo is in. Here’s the script I use to tell me.
MNU, my macOS menu bar utility that lets you call up regularly used command line operations and more, now supports iTerm2, the popular alternative to macOS’ own Terminal app.
I recently had a rather large number of screenshots to process: specifically to crop them down to a small area about a third of screen width in and two-thirds of its height down. I could have done this manually, but it’s easy enough to make mis-crops when you’re cropping a couple of images by eye, let alone a 100 or so. The solution? Get your Mac to do it for you. Here’s how.
For a while, running commands and scripts in macOS’ Terminal has felt slower than it should, especially when opening Terminal for the first time. Clearly my .zshrc file was being run, but there was a very noticeable pause between the completion of the script and before the prompt appeared. The gap was much less on my M1 Mac than my Intel machine, but still noticeable. Got the same problem? Here’s how to fix it.
Last week I announced the release of a new version of PreviewMarkdown that will preview YAML front matter in Markdown files. Work on that release prompted me to code a new app that enables QuickLook previews and Finder icon thumbnails of YAML files.
Version 1.3.0 of PreviewMarkdown has just been released. Its key new feature: you now have the option to view YAML front matter in Markdown file previews. This is really handy if, like me, you use a static site generator and use YAML to record content metadata at the top of your Markdown page files.
PreviewMarkdown’s Thumbnailer component, an App Extension which generates Finder icon thumbnail previews of Markdown documents, recently started showing some odd behaviour. Tracking down the cause provided some interesting insights into writing macOS software for a multi-threaded environment.
I’d like to introduce you — if you’re not already acquainted — to the Z Shell’s incredibly handy function zmv. If you ever need to change at the command line the names of a batch of files consistently, it’s the tool you’ll want to turn to first. It’s not well known, and having been given the nod by a colleague, I thought I’d explore and pass on some notes about taking advantage of it.
A couple of macOS releases or so ago, Apple introduced app extensions: self-contained modules that are bundled within apps to deliver functionality to the wider operating system. But how do apps and their extensions share information between themselves, in particular users’ preferences?
Let the great Homebrew migration begin. Yes, Homebrew now has native support for Apple’s ARM64-based M1 chip. The latest version, 3.0.0, released 5 February, will run nicely on your Apple Silicon Mac. There’s a catch, of course. Well, several catches: first, not all of the tools you can install using Homebrew are M1 native yet and, second, Homebrew doesn’t offer explicit migration instructions, that I could find at least.
