Basilisk

Google’s AI overview finally picked up the news on our entry to the Python type checker leaderboard

PEP 827 会把 TypeScript 那套条件类型和映射类型带进 Python。 也就是说,每个类型检查器突然都得在类型层面上跑一门小型函数式语言。 Basilisk 有干净的 Rust 内核,没有历史包袱。听起来像是个挑战。

PEP 827 would bring TypeScript-style conditional and mapped types to Python. Which means every type checker suddenly has to evaluate a small functional language at the type level. Basilisk has a clean Rust core and no legacy. Sounds like a challenge

Type checking is more important than ever with the advent of Free-Threaded Python. Read about it here basilisk-python.dev/blog/free-thre…

This is what you get at the end of every run — an interactive flame graph.

Every Python codebase has that one line eating your CPU. Basilisk finds it. One click in VS Code: your code runs, hot lines light up right in the editor, and you get a flame graph at the end. No pip install. No decorators.

🎉 Basilisk 现已被 Python 官方 python/typing 收录，并以 100% 的满分成为唯一取得完美 PEP 符合性得分的类型检查器！结果详见官方仓库👇 github.com/python/typing/…

Basilisk is now part of the Python typing canon and we achieved a perfect PEP score. See the results on the Python typing repo github.com/python/typing/…

We’re looking for Python and performance experts to help audit our PEP conformance scores (100%) and benchmarks. We think they’re pretty amazing and we’re planning to submit to the typing repo. Reach out if that sounds like you

I got fed up on development with Windows. Just switched to Linux (Arch + GNOME). Looking for recommendations on extensions and apps to add for development!

Python 冷知识:默认参数只在函数定义时求值一次,而非每次调用时。这正是 def f(x=[]) 的经典陷阱——这个列表会在多次调用间共享。正确做法:用 x=None,在函数体内初始化。🐍

in Python, default arguments are evaluated once, at function definition — not each call. That’s why def f(x=[]) is a classic footgun: the list persists across calls. Use x=None and set it inside. 🐍

Basilisk seems to be getting some downloads on vscode forks. We’re happy to support this community

This is our write-up on the Astral acquisition by OpenAI basilisk-python.dev/blog/openai-ac…

Python 3.15 已进入后期 beta 阶段,预计将于十月正式发布。Beta 2 已于 6 月 2 日发布,正式版前还会有更多 beta 版本。已确认的新特性包括:惰性导入(PEP 810)、内置 sentinel,以及 frozendict。 @pythonbytes

Python 3.15 is in late beta, heading toward an October release. Beta 2 landed June 2 , with more betas to come before the final. Confirmed features include lazy imports (PEP 810), a built-in sentinel, and frozendict. @pythonbytes

@tunji_oyeniran @zeddotdev Our Zed extension is pretty awesome… Will post more about it soon

Zed Editor is cooking. And it already tastes delicious. Love this upcoming features in the Roadmap. cc @zeddotdev

@SheltonLouisGT Nothing is clear at the moment, but we’re confident that there are viable alternatives to ruff, even though ruff is has served the Python community so well. Continuing with ruff is definitely our preference

@BasiliskPython I don't think this is good

Breaking story: OpenAI Acquires Astral ruff is a foundational dependency for Basilisk, but we are committed to open source licensing so this could mean big changes if OpenAI decide to close the Astral source

突发消息：OpenAI 收购 Astral ruff 是 Basilisk 的一个基础依赖。我们坚持开源许可——若 OpenAI 今后将 ruff 的新版本闭源，这可能带来重大影响。（现有的 MIT 版本永远开源，我们也可据此 fork。）
