beartype VS toit

I wish more people started using Beartype, it makes Python bearable

I saw this on /r/Python the other day...

As other folks have commented, type hints are now a big deal. For static typing the best checker is pyright. For runtime checking there is typeguard and beartype. These can be integrated with array libraries through jaxtyping. (Which also works for PyTorch/numpy/etc., despite the name.)

Maybe you're looking for https://github.com/beartype/beartype for runtime type enforcement; it's only at function calls, though, but probably a decent solution for codebases that are not completely typed for MyPy or pyright.

It is though, if you add a type checker to your pipeline and use it without any escape hatches such as `Any` or `type: ignore`, you are essentially making the promise that your code is statically typed. But I say it is a matter of perspective because in my opinion runtime type checking should be avoided if we can get away with statically typed code, but there are type checkers that perform runtime type checking via annotations such as [Beartype](https://github.com/beartype/beartype) (with some trickery like assuming homogenous data structures as to not have to check every element of every structure). Anyway the definition of "type safe" is not 100% even in compiled languages.

There is the beartype project.

Personally I find working around mypy's quirks to be more effort than it's worth, so to offer another option: typeguard or beartype can be used to perform run-time type checking.

It uses toit, a high-level language, and is thus quite easy to learn. At the same time it's an order of magnitude faster than micropython.

We have been faced with the same question and decided to open-source pretty much all of our product (https://github.com/toitlang/toit).

I also really like MicroPython! Having said that, I have been working on an alternative to it for a number of years now -- primarily to provide a more robust and performant high-level alternative to C and Rust on the ESP32-family of chips:

I'd love to pick your brain and fully understand your experience with MicroPython. I've been doing programming languages for a number of years now, and I find that it is incredibly useful to understand what developers appreciate (and dislike) about the available stacks.

Thank you for the mention!

I have been working on the Toit language for the ESP32 for a number of years now -- and it has been an enjoyable challenge to build an open source stack capable of supporting live reloading on a micro-controller that can run for years on batteries.

We use it for some of our tools, so it's possible (and works nicely). Our LSP server was initially written in Toit: https://github.com/toitlang/toit/tree/master/tools/lsp/serve...
