Speed would be nice, but more than that I want it to also manage Ruby installs. I’m infuriated at the mess of Rubys and version managers.
So you can run
uv run poe docs
Instead of
uv run sphinx-build -W -b dirhtml docs/source docs/build
Many languages have a task runners baked into their package manager, but many others don’t. In Ruby it’s roughly the equivalent of Rake.
> mise can be used as a drop-in replacement for asdf. It supports the same .tool-versions files that you may have used with asdf and can use asdf plugins through the asdf backend.
> It will not, however, reuse existing asdf directories (so you'll need to either reinstall them or move them), and 100% compatibility is not a design goal. That said, if you're coming from asdf-bash (0.15 and below), mise actually has fewer breaking changes than asdf-go (0.16 and above) despite 100% compatibility not being a design goal of mise.
> Casual users coming from asdf have generally found mise to just be a faster, easier to use asdf.
I never understood the real need for chruby rvm etc... - I manage everything, all programs, in a versioned AppDir manner. (Note: I am not using GoboLinux; I use a modified variant. GoboLinux gave the correct idea though.)
> each program in a GoboLinux system has its own subdirectory tree, where all of its files (including settings specific for that program) may be found. Thus, a program "Foo" has all of its specific files and libraries in /Programs/Foo, under the corresponding version of this program at hand. For example, the commonly known GCC compiler suite version 8.1.0, would reside under the directory /Programs/GCC/8.1.0
It's not really that easy being really different in the Linux packaging world.
I think all of ruby, including the ecosystem as well as how ruby is governed, needs to be considered. In particular with ruby constantly declining and losing user share. That is not good. That should change.
At this point I've used rbenv, rvm, asdf, mise, and one other whose name isn't coming to mind. Not to mention docker containers, with or without any of those tools.
I don't mean to project any particular complaint onto you, and I'm curious what part of it is infuriating? Each of the version managers I've used has functioned as advertised, and I'm able to get back to work pretty smoothly.
One challenge, as I see it, is that there are three kinds of Ruby projects that need to take different approaches to the matter, in increasing level of complexity:
(1) Developing a longer-lived, deployed or distributed project. Here you should definitely use both the Gemfile Ruby version and a .ruby-version file. You're normally only targeting one version at a time, but contributors and/or users are very unlikely to somehow accidentally end up using the wrong Ruby version without getting a very obvious notification that they are using the wrong Ruby version. That's annoying to encounter, but not difficult to solve once you know that the concept of a "version manager" exists.
(2) Hacking on your own small project or just banging out a script. You just want to run some Ruby version and get to it. You probably should default to the latest, unless there's some dependency requiring a lower version, and you might not know that until after you've gotten started. The inverse issue might also occur, e.g. you installed Ruby 3.1 a few years ago, you start hacking, and now you want to pull in a gem version that requires Ruby 3.4. You can manage this by putting the Ruby version in your Gemfile, or using a .ruby-version file, or both, but if you're relatively green and just diving in, this might not be on your radar.
(3) Developing a gem. You probably want to test/validate your gem across multiple Ruby versions, and possibly even different versions of your dependencies. You obviously don't want to lock yourself into a single Ruby version, and use of a .ruby-version file is inappropriate. There is tooling to do this, but it takes some learning to be able to utilize.
My belief is that it is worth it for install documentation for category (1) to be a little more explicit about how to get up and running. For category (2), I don't know what the right answer is, but I understand the potential pain points.
What I was most curious about is whether AlphaSite's complaint was with a specific version manager, or the fact that multiple options for version managers exist, or even the need for version managers at all?
I can relate to the "I wish we didn't need a second tool", but it doesn't seem like much of a mess.
If python version changes in an uv-managed project, you don't have to do any extra step, just run "uv sync" as you normally do when you want to install updated dependencies. uv automatically detects it needs a new python, downloads it, re-creates the virtual environment with it and installs the deps all in one command.
And since it's the command which everyone does anytime a dependency update is required, no dev is gonna panic why the app is not working after we merge in some new code which requires newer python cause he missed the python update memo.
