rv plan and progress update

For the last ten years or so of working on Bundler, I’ve had a wish rattling around: I want a bigger, better dependency manager. It doesn’t just manage your gems, it manages your ruby versions, too. It doesn’t just manage your ruby versions, it installs pre-compiled rubies so you don’t have to wait for ruby to compile from source over and over. And more than all of that, it makes it completely trivial to run any script or tool written in ruby, even if that script or tool needs a different ruby and gems than your application does. For the entire ten years of daydreaming, I’ve been hoping someone else would build it and I could just use it. Then I discovered that someone did build it… but for Python. It’s called uv. In August 2024, uv version 0.3 shipped, and it had all the features I had wished for, and even more that I hadn’t thought to wish for. .
