Project Introduction

Summary

mise is a version manager and task runner designed to streamline polyglot development workflows. It handles tool version switching, environment variable management, and task execution from a single configuration source.

Problem Solved

Developers often struggle with managing multiple versions of programming languages and tools across different projects, inconsistent environment variables, and complex, disparate task execution scripts. mise provides a unified solution to these problems, simplifying setup and ensuring consistency.

Core Features

Polyglot Version Management

Automatically detects and loads the correct tool versions (like Node.js, Python, Ruby, Go, etc.) based on project configuration.

Environment Variable Sourcing

Manages environment variables per project or globally, ensuring consistent development setups.

Powerful Task Runner

Define and run complex project tasks with ease, replacing traditional task runners or scripts.

Fast Execution

Built for performance with a focus on speed and minimal overhead.

Tech Stack

Rust
Shell Scripting
YAML Configuration

Use Cases

mise can be applied in various scenarios where managing development tools, environments, and tasks is crucial for efficiency and consistency.

Scenario 1: Multi-Project Development

Details

Seamlessly switch between different versions of Node.js, Python, Ruby, Go, and other tools when navigating between project directories.

User Value

Eliminates the need for manual version switching or environment setup scripts per project, speeding up context switching.

Scenario 2: Team Environment Standardization

Details

Standardize the exact versions of tools and environment variables required for a project across a development team using a single configuration file (`.mise.toml` or `.tool-versions`).

User Value

Ensures all team members work with the same environment, reducing "it works on my machine" issues and simplifying onboarding.

Scenario 3: Automated Project Tasks & CI/CD

Details

Define and run project-specific build, test, or deployment commands using mise's task runner, integrating environment variable loading automatically.

User Value

Simplifies task definition and execution, making CI/CD pipelines more robust and easier to maintain by handling tool versions and environments.
