A couple of days ago I discovered mise (pronounced "meez"). It's a polyglot tool version manager similar to asdf or pyenv, and an environment manager, like direnv, that is fast, reliable, has a declarative configuration and feels as good as cargo.

I got rid of hatch which I had previously been using only for downloading Pythons from python-build-standalone with the command hatch python install all --update. I have also stopped using Node from Homebrew, and removed custom scripts from my dotfiles that were used to keep pipx installations synchronized between my work and personal laptops.

My ~/.config/mise/config.toml now looks like this:

[tools]
python = ["3.12", "3.11", "3.10", "3.9", "3.8"]
node = "lts"
usage = "latest"  # required by mise itself
"pipx:maturin" = "latest"
"pipx:poetry" = "latest"
"pipx:pypi-command-line" = "latest"
"pipx:watchfiles" = "latest"

[settings]
experimental = true  # pipx backend is experimental

I have also started using mise's environment management feature. I placed the .mise.local.toml file containing organization-specific environment variables in the folder with work repositories:

[env]
PIP_INDEX_URL = "..."
CERT_PATH = "..."
GITLAB_TOKEN = "..."
...

Everything is great so far.
