Plugins

mise uses asdf's plugin ecosystem under the hood. These plugins contain shell scripts like bin/install (for installing) and bin/list-all (for listing all of the available versions).

See https://github.com/mise-plugins/registry for the list of built-in plugins shorthands. See asdf's Create a Plugin for how to create your own or just learn more about how they work.

Core Plugins

mise comes with some plugins built into the CLI written in Rust. These are new and will improve over time. They can be easily overridden by installing a plugin with the same name, e.g.: mise plugin install python https://github.com/asdf-community/asdf-python.

You can see the core plugins with mise plugin ls --core.

Plugin Authors

https://github.com/mise-plugins is a GitHub organization for community-developed plugins. See SECURITY.md for more details on how plugins here are treated differently.

If you'd like your plugin to be hosted here please let me know (GH discussion or discord is fine) and I'd be happy to host it for you.

Plugin Options

mise has support for "plugin options" which is configuration specified in .mise.toml to change behavior of plugins. One example of this is virtualenv on python runtimes:

[tools]
python = {version='3.11', virtualenv='.venv'}

This will be passed to all plugin scripts as MISE_TOOL_OPTS__VIRTUALENV=.venv. The user can specify any option and it will be passed to the plugin in that format.

Currently this only supports simple strings, but we can make it compatible with more complex types (arrays, tables) fairly easily if there is a need for it.
