Mise integration for Sublime Text

A Sublime Text package that integrates with mise.

What this does

Environment loading

This package will load the environment variables that Mise provides when you open a project and clean up after itself after changing.

This feature looks through the folders configured in your sublime-project file, trying to find any that have a mise.toml or mise.local.toml in its root.

The package will load environments from any top-level folders, but it will give priority to ancestors when there are clashes.

I'll illustrate with an example: if your directory structure is like this:

root
├── mise.toml (defines FOO=1)
└── server
    ├── mise.toml (defines BAR=2)
    └── component
        └── mise.toml (defines BAZ=3 and FOO=9)

This package will load the following variables:

FOO=1
BAR=2
BAZ=3

Build system

The package provides a build system for the mise task runner. When using the provided build system it will:

• List available tasks
• Interactively prompt you for a task to run
• Execute that task and how syntax-highlighted output in Sublime Text's build output panel

Commands

Another way of interacting with Mise is through the “Mise: Run task” command, available in the Command Palette. This will fetch the available tasks defined in your project and give you a menu to select from. The selected task will be ran.

There is also a command to execute mise trust from the editor. It is available in the Command Palette as “Mise: Trust config”.

In order to find the directory from which to run Mise for a command, the preference is: 1. The directory of the currently-open file. 2. The first directory you have in the sidebar/project. 3. Your $HOME directory.

Installation

Package Control

1. Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P)
2. Search for “Package Control: Install Package”
3. Search for “Mise” and install

Manual

Put this repository inside your Sublime Text Packages folder.

Requirements

• mise must be in Sublime's PATH

Limitations and future work

1. It hasn't been tested on Windows. Let me know if it works or not so I can fix it/remove this line.
2. Doesn't support all the config file paths Mise supports. That means if you store your mise config in e.g. mise/config.toml, Sublime won't automatically offer you Mise as an option for building. Environment loading also won't work.
3. Planned features (read: will likely never bother, feel free to open a PR)
   • Performance: checking mise config ls --tracked-configs might be faster than upglobbing or trying to check if any folder has a mise config. (This also fixes item #2 above). Note this requires mise v2025.1.5 or newer.
   • A “Mise Exec” build system that prompts the user for any command and does mise exec -- $input
