Me: How can you wrap NSTextView events to go through a ReSwift store? ChatGPT: It’s not clear what you’re asking. Could you please provide more information or context? I’m a large language model trained by OpenAI, so I don’t have the ability to browse the internet or access in … | Continue reading
EmacsConf 2022 is this weekend! It starts 15:00 CET (German Time), aka 9am-5pm Toronto/EST. There’s a metric crapton of talks and demos and stuff. Recent years have been good to the Emacs web community. Overview: https://emacsconf.org/2022/talks/ The website is great; it includes … | Continue reading
Emacs users sooner or later disable all the GUI stuff, and usually also get rid of system alerts and file pickers. But if you just once want to pick a file using your operating system’s file picker, these three temporary variable overrides will do: (let ((last-nonmenu-event nil) … | Continue reading
I may be 7 years late or so – but until last week, I didn’t realize that didSet property observers would fire when the observed property hasn’t actually changed. All you need is a mutating func that doesn’t even need to mutate. Observation This can be illustrated with a simple pi … | Continue reading
I just wanted to write one short post. Then I discovered that I didn’t yet have a wiki page for a central concept. Then I needed another one. And an hour later, here we are. New wiki pages: Domain-Driven Design Aggregate Root Bounded Context Entity Value Object … | Continue reading
Emacs’s outline-mode only has font settings aka “faces” for 8 outline levels; then they wrap, so level 9 looks like level 1 and so on. org-mode inherits these faces, and thus also only defines 8 styles. That’s more than enough, I believe, to have some visual variety in your outli … | Continue reading
I discovered this piece of news by accident, and I want to share this with you because I believe this is a very interesting case, providing insight into open source projects, even those that are wildly popular. Gitea is an open source “git forge” (think: GitHub; or rather GitLab, … | Continue reading
This Thursday (in 2 days), I’ll be doing a short presentation of plugin systems via JavaScriptCore, plus an interactive demo and something for attendants to play around with. (Fingers crossed I finish it in time ) You can join via Zoom. It’s free, and should be fun :) Time: 202 … | Continue reading
NSTableView comes with a couple of default shortcuts in an override of its keyDown(with:) method. These aren’t mentioned anywhere, so Xcode’s documentation quick help will repeat the NSView docstring to you, saying: The receiver can interpret event itself, or pass it to the sys … | Continue reading
In recent weeks, I’ve been feeling quite restless. There’s not enough time, too many things I just can’t seem to take care of. You probably know that feeling – or rather, the attitude towards things. There’s a couple of things that need to be sorted out. And there’s stuff that ar … | Continue reading
I have Screen Time enabled and synced across devices for quite a while for top secret reasons. My Mac can list Screen Time activity from my mobile devices many weeks in the past. The iPad itself, though, can’t show anything that was before last Thursday. Huh? knowledgeC.db and th … | Continue reading
Variable row heights in your NSTableView might be broken in your apps on macOS Ventura 13.0 – it’s fixed with the upcoming 13.1, but that’s only available as a beta at the moment. When you replace table contents by calling aTableView.reloadItems(), this will ingest the new data a … | Continue reading
Happy macOS release week, everyone! Earlier this week, macOS 13 Ventura was released. It’s a point-oh release, so you might want to sit this out a bit and wait for 13.1, as is common practice. (My main developer machine is running Big Sur, and I won’t be updating for a couple of … | Continue reading
This list was extracted from my reaction to Sketch laying off 80 employees for higher visibility. Update 2022-10-18: There’s a spreadsheet overview of 57 Sketch alumni you can check instead! Here are some amazing ex-Sketch folks that I’ve found thus far who are for hire now: A … | Continue reading

For a plain text (not rich text/RTF) NSTextView, I found that: writablePasteboardTypes contains only "NSStringPboardType" by default. readablePasteboardTypes contains a lot of types, but only "NSStringPboardType" for plain text copying.- An NSPasteboard understands both "NSStr … | Continue reading

The metaphor of the “black box” is very common in programming. It is so general that it’s nearly meaningless; but it summarizes a lot of specialized principles nicely and shows a unifying principle. A black box is characterized by: a boundary inputs outputs A black box has i … | Continue reading
Here’s a short definition of the two terms: Cohesion is about how well elements within a module belong together and serve a common purpose. Coupling is about how much one module depends or interacts with other modules. Thus, cohesion is an intra-module concern whereas coupling … | Continue reading
When you work with NSTextView and happen to use insertText(_:) to programmatically insert text, you get an undoable action for free. This might give the impression you get undo/redo functionality for free. Eventually, you’ll notice how other changes don’t have an affordance in th … | Continue reading
Reactive, declarative code is sequentially cohesive: you have a sequence of events and reactions to events, and it’s pieces are tied together real close. The processing chain itself is then a function or feature of the app. The chain of operators is a thing itself; the step-by-st … | Continue reading
Ever since Brett Terpstra posted about ⌘← to jump to the first character of the line back in 2014, I’ve used behavior like this in Xcode. Nowadays, ⌘⌫ automatically deletes up to the beginning of the line, stopping at whitespace. That’s quite handy to rewrite the current line. Th … | Continue reading

On Reddit, there was a recent thread called “Your dependency on external packages reduce with experience”. I have been using zoom-window in the past to temporarily “unsplit” buffers. So this: ┌───┐╔════════════╗┌─────┐ │ │║ ║│ │ │ A │║ C ║│ B │ │ │║... | Continue reading

YouTube video of today's evening sketching This time I remembered to record our weekly sketch-together over Discord. Here’s a 4x speed version with narration of this evening’s sketches.

When you have nested and complex UI components with multiple sub-view controllers, passing an optional output port (event handler or delegate) down the tree is cumbersome. There are two straight-forward approaches: Sub-components use the output port directly: When you inject th … | Continue reading
My blog posts here usually have a line like: tags: [ swift, xcode, codesigning ] For tags I don’t use a lot, I sometimes don’t remember how to write them. So I do the only sane thing – and go to my website’s list of tags and look for a match. Got annoyed by that now after a coup … | Continue reading
