tox VS mise

Tox is a powerful tool in Python development, primarily used for automating and standardised testing across multiple environments. It’s part of a larger vision of easing the packaging, testing, and release process of Python software. You should consider using tox in the following scenarios if your application needs to run across different Python versions, tox can help ensure your code works consistently across all these versions; If your project has complex dependencies, tox can manage and isolate these dependencies in different environments.

Another less heavyweight solution than Docker is Tox – handy for when you need to test software with multiple different versions of Python.

Where are you getting "mise uses asdf" from? mise is simply compatible with all asdf plugins. Not the same thing.

It's even said almost at the top of the README.md in the "30 seconds demo" section:

"The following shows using mise to install different versions of node. Note that calling which node gives us a real path to node, not a shim."

So yes, mise does not use shims. It only manipulates $PATH. I did benchmarks a while ago and that definitely and consistently has shaved some milliseconds off of the startup times of my tools.

mise borrows the plugins from asdf, which also makes it non-cross platform. Interesting discussion on this topic on their GitHub: https://github.com/jdx/mise/discussions/66

Solutions considered include adopting the vfox plugin system or transpiling all asdf plugins to ShellJs.

Now I know that vfox exists.

Why not just use a tool like asdf (https://asdf-vm.com/) or mise (https://mise.jdx.dev/)?

These tools have the advantage of not being multi-taskers and can manage version for all your tools. You wouldn’t need pyenv and npm and rvm and…

We’ve even started committing the .mise.toml files for projects to our repos. That way, since we work on multiple projects that may need multiple versions of the same tool, it’s handled and documented.

direnv + mise does exactly that. When I cd to various directories I get different env vars, it's pretty neat. Setting aliases would just be a case of adding them.

https://github.com/jdx/mise/discussions/1525 for an example of how I use direnv with mise.

Installed bun js runtime (I used mise, btw)

Not nix based, but I really like https://github.com/jdx/mise too to manage dev tools.

It’s a modern version of https://github.com/asdf-vm/asdf written in Rust.

The purpose of a version manager is to help you navigate or install any tools for development easily. Version Manager can be one tool for each dependency (e.g. NVM, g) or One tool for all dependencies (e.g. asdf, mise).
