GraphQL is an incredible piece of technology that has captured a lot of mindshare since I first started slinging it in production in 2018. You won’t have to look far back on this (rather inactive) blog to see I have previously championed this technology. After building many a React SPA on top of a hodge podge of untyped JSON REST APIs, I found GraphQL a breath of fresh air. I was truly a GraphQL h

FreeBSD では 2024-05-31 に 200112 から 200809 への変更がようやく行われました（一度間違えて 200808 と書いてしまっていますが）。 https://cgit.freebsd.org/src/commit/?id=2e30926a68 https://cgit.freebsd.org/src/commit/?id=6e0278408e macOS は FreeBSD のユーザーランドのコマンドを使用しているため、そのせいで 200112 のままだった可能性も考えられますが、シェルやカーネルは FreeBSD のものではないため、FreeBSD が変更になったからと言って macOS が更新されるとは限らないでしょう。Solaris 10 と 11 ではディレクトリごとに準拠バージョンが異なるバイナリが配置されており以下のようになります。Solaris
TypeScript 5.5で、@graphemeclusterさんによって正規表現リテラルの構文チェックが導入されました🎉 この構文チェックによって、正規表現に間違いがあった場合、事前にTypeScriptがエラーを出力してくれます。 この機能について、次のことが気になったので調べてみました。 どんな構文がエラーになるか なぜ導入されたか どうやってチェックしているか JavaScriptで実行できるがTypeScriptでエラーになる構文はあるか ESLintとのカバー範囲の違い 本記事に関して、誤り等があれば指摘いただけると嬉しいです。 どんな構文がエラーになるか TypeScript 5.5では、正規表現に関するエラーメッセージが40個程度追加されています。 例えば、下記のような構文は、5.5でエラーになります。 // 存在しないフラグ var re = /a/b; // エラー
イテレータについて完全理解するぞ！！！！ 皆さん、Go1.23で導入予定のイテレータすごい楽しみですよね？ 筆者はすごい楽しみです。Go1.18でジェネリクスが導入されて書き方の幅が広がったように、今回のイテレータもGoの書き方の幅を広げる機能になるのではと予想しております！ https://github.com/golang/go/issues/61405 を見ると分かるように「add range over int, range over func」の機能はGo1.23のマイルストーンに積まれています。 「range over int」の機能についてはGo1.22で既に実装されています[1] 。「range over func」は来たるGo1.23に実装予定だと思われます。このブログでは、導入予定の型/関数とその使い方を深ぼっていきたいと思います！ このブログの中では「range ove
Today we’re excited to announce the release of TypeScript 5.5! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

The last year has been a great one for WebKit. After unveiling Safari 17 beta at WWDC23, we’ve shipped six releases of Safari 17.x with a total of 200 new web technologies. And we’ve been hard at work on multiple architectural improvement projects that strengthen WebKit for the long-term. Now, we are pleased to announce WebKit for Safari 18 beta. It adds another 48 web platform features, as well a

CSS Length Units | CSS-Tricks
Overview Many CSS properties accept numbers as values. Sometimes those are whole numbers. Sometimes they’re decimals and fractions. Other times, they’re percentages. Whatever they are, the unit that follows a number determines the number’s computed length. And by “length” we mean any sort of distance that can be described as a number, such as the physical dimensions of an element, a measure of tim
This is why you should never use parser combinators and PEG
Let me tell you why you should (nearly) never use PEG (parsing expression grammars). Nearly everything I will say applies to parser combinators (parsec in Haskell, nom in Rust), too. So, don't use PEG. Use CFGs (context-free grammars) instead. They are more natural. I feel that CFGs more naturally represent how we think. Thus when you have some language in your head and you try to write it down as

F# developer stories: how we've finally fixed a 9-year-old performance issue - .NET Blog
Programming language authors have to think about many things at once: overall language design, runtime dangers, possible feature misuse, backward compatibility, forward compatibility, and so on. All these aspects, together with communication hiccups and time constraints, might get in the way of some seemingly clear and manageable problems. The Bug The story began in the summer of 2015 with this is
Vitest Browser Mode · vitest-dev/vitest · Discussion #5828
It's been some time since we gave any update on the Browser Mode, and Vitest 2.0 seems like a good time to explain how we feel about it. And we have a lot of plans! The initial purpose of Vitest was to allow running tests without a complex Jest setup but with the battle-tested Jest API everyone is already familiar with. This also meant faking the browser environment (with jsdom or happy-dom). With
An origin trial for a new HTML <permission> element | Blog | Chrome for Developers
There are a number of imperative methods for asking for permission to use powerful features like location access in web apps. These methods come with a number of challenges, which is why the Chrome permissions team is experimenting with a new declarative method: a dedicated HTML <permission> element. This element is in origin trial from Chrome 126, and ultimately we hope to standardize it. Imperat

01 june, 2024 most of rust discussions nowadays revolve around memory safety, and how it is safer than C / C++ / zig / go / whatever language is being trashed on twitter that day. while yes, that is true - not that the bar for most of these is particularly high - what I think is the main point of the language is always glossed over: correctness. when one tries to criticize any of the aforementione

Last year, a colleague introduced me to the Interop Accessibility project. I immediately resonated with its charge to “improve the state of accessibility across the entire web, regardless of which platform, browser, or assistive technology.” The project’s mission was compelling but it also represented, from my perspective, a transformative example of shifting accessibility to the level of web plat
The CSS WG resolved to add if() to CSS, but that won’t be in browsers for a while. What are our options in the meantime? A couple days ago, I posted about the recent CSS WG resolution to add an if() function to CSS. Great as it may be, this is still a long way off, two years if everything goes super smoothly, more if not. So what can you do when you need conditionals right now? You may be pleased
Node.js includes a built-in module called performance hooks for precise performance measurement. But why use it when you can simply log timestamps and calculate the difference between two dates? At least because it is precise. The module uses a monotonic clock that allows you, as a user, to make performance measurements and be sure that they are not corrupted. At first, I struggled to understand h
Use context-free grammars instead of parser combinators and PEG | Hacker News
Parsing is an application domain where I'd expect more hard logic and less soft feelings than in this article."I feel that CFGs more naturally represent how we think" but "All this doesn't apply to situations where you trying to parse some language, whose specification explicitly says that the language is based on PEG formalism" A terrible context free grammar (with left and right recursion, not a
