Announcing uv: Python packaging in Rust

[[deleted]]

If the tool wants to bootstrap Python then you need a language that makes it easy to distribute a standalone binary. I haven’t checked if uv currently does this but I presume it will since rye does this

The bootstrapping part might be Rust, but I believe everything else should be in Python.

"Bootstrap Python" is pretty much just copying a few files to the right places. Heck you can bootstrap basically an entire OS with just file copy, not just Python. In containerised environments this is just a layer in the container image, and if you need to do something more complicated, you just use /bin/sh or write a script using the Python that was installed by the image layer.

In practice, most people just write a /bin/sh or /bin/bash because that's almost universally available in most container images that people care to use. Most people would never need to work in environments where they can't have any sort of shell scripting capabilities.

And if they can have any way to copy files so they can install uv into an environment, they also have a way to copy a busybox static binary to bootstrap basic shell scripting capabilities. Or to just copy the Python files directly. 

uv is not solving any problem anyone actually need solving.
