After almost a week of refactoring and experimenting with several different approaches, I've updated my Zig nD SIMD vector library to be compatible with the latest Zig 0.15.1, and at the same time cleaned up some internals.

The solution I settled on is a mix of techniques proposed by others, and was needed due to the removal of the struct/namespace-merging syntax in the new Zig version, which this library heavily relies on. I don't like that the new source code is now more than 2x larger and involves a huge amount of duplication to address the many special cases of supported operations for different vector sizes and types. I might still take another pass to eliminate those (by using `@compileError()` for unsupported cases), but that'd be an implementation detail downstream users don't have to care about. I tried AOT code generation as well, but the special case handling made this feel less maintainable...

UPDATE: The only breaking change is the handling of vector swizzles. I had to remove the hundreds of named swizzle functions and replaced them with a single (comptime optimized) `.swizzle(vec, pattern)`, e.g. `.swizzle(vec, "xxyy")`...

If you're interested, the new code is here:

RUG — малоизвестный, но фундаментальный принцип Clean Code

Многие разработчики при обсуждении основ Clean Code называют одни и те же принципы — чаще всего упоминаются DRY , KISS и YAGNI . Эти концепции прочно закрепились в профессиональном сообществе и воспринимаются как обязательная часть хорошего кода. Принцип RUG упоминается значительно реже. Чаще всего о нём узнают с опытом, а многие применяют его интуитивно, даже не подозревая, что для этого подхода существует отдельное название и формулировка. Сегодня я хочу поговорить о принципе RUG и о том, какие рекомендации он даёт по написанию программного обеспечения. RUG ( Repeat Until Good ) — это принцип, который говорит: можно повторять один и тот же код, пока это разумно. На ранних этапах разработки важнее просто реализовать логику, исходя из текущих требований, чем пытаться сразу создать «идеальную» абстракцию. В этот момент задача — как можно быстрее получить рабочее решение, которое отражает текущие знания о системе. Но со временем, когда одна и та же логика начинает встречаться всё чаще, становится очевидно, что её удобнее и правильнее выделить в отдельную, чётко оформленную абстракцию, чтобы избежать дублирования и упростить дальнейшую поддержку. Мы используем этот принцип каждый раз, когда пишем код. Ведь практически любую логику можно сделать более абстрактной и масштабируемой — вопрос лишь в том, когда наступает подходящий момент для этого. Я буду использовать TypeScript , так как этот язык знаком большинству разработчиков. 😁

“This #refactoring was done by an LLM, and then reviewed by a human. [..] The break became a continue, turning errors into infinite loops. [..] small enough change in a larger code movement that we didn’t notice it during code review.”

Queue the LLM-apologists and something about “thou shalt have test cases” in 3..2..

(Though I feel I should put that tag into scare-quotes)

The ranged W command was great to perform a Move Method #refactoring to another class.

W appends a selected block from the current file to another file. Then you can edit the other file and move the appended block to its correct position with the m command. A few substitutions later, and the Move Method was done without leaving ed.

iOS Dev Tools & Techniques Xcode Key Bindings to Make Refactoring Less Painful Quality Coding with Jon Reid

Example of scope, I currently want to invert the condition on the name here:

*34,40n
34 } else {
35 if (item.quality > 0) {
36 if (!item.name.equals("Sulfuras, Hand of Ragnaros")) {
37 item.quality = item.quality - 1;
38 }
39 }
40 }

This is fine if I do one thing at a time.

Also: ed edits could be a great format for #refactoring toots 🤔

It's going well so far:

*!git log --oneline | cut -d' ' -f2- | tac
Starting point
Simplify for loop
Invert the first if
Split first if
Invert if on sulfuras
Permute ifs for sulfuras
Join first 'if else's

I think I can now say it's totally doable and even worth repeating this kata a few times.

#refactoring

Totally random thought: would I be able to do the Gilded Rose kata using only the ed text editor in a reasonable time?

Goals:
1) have fun,
2) look like a fool,
3) learn enough ed to later be able to script complex text changes across files,
4) also level up in sed and vim

Reason: ed(1) is the standard Unix text editor.
