Mise Configuration

About

Establishes `.mise.toml` as the single source of truth for all project configuration, from environment variables to tool versions. This skill guides you in creating robust, reproducible developer environments by centralizing settings and secrets. The core principle ensures that scripts remain backward-compatible, functioning seamlessly with or without `mise` installed by using standard environment variable patterns with default fallbacks. It is ideal for refactoring hardcoded values, automatically managing Python virtual environments, and creating a consistent setup for an entire team.

Key Features

• Utilizes special directives to load `.env` files, extend `PATH`, and source shell scripts.
• 1 GitHub stars
• Centralizes configuration in `.mise.toml` using backward-compatible script patterns.
• Automates Python virtual environment (`.venv`) creation and activation.
• Leverages Tera templating for dynamic and conditional environment variables.
• Provides clear implementation steps and anti-patterns for robust configuration management.

Use Cases

• Standardizing a team's development environment by pinning tool versions and automating setup.
• Refactoring a project to remove hardcoded values and centralize them in a single `.mise.toml` file.
• Creating a new project with a reproducible configuration, including automatic Python venv management.
