# Mise

> Install missing language runtimes and dev tools via mise. Use when (1) a command fails due to missing runtime (e.g. node not found, python3 not found, go command not found), (2) user asks to install/setup a language runtime or SDK (node, python, go, rust, java, ruby, etc.), (3) user mentions version management for languages, or (4) setting up a new development environment.

# mise

Runtime version manager. Replaces nvm/pyenv/rbenv/asdf.

## Install Runtime

```bash
# Install globally
mise use -g node@lts
mise use -g python@3.12
mise use -g go@latest

# Install for current project (creates mise.toml)
mise use node@20
```

## Common Commands

```bash
mise ls                  # List installed
mise ls-remote node      # Available versions
mise where node          # Install path
mise install             # Install from config
mise uninstall node@20   # Remove version
```

## Available Runtimes

**Core (native):** node, python, go, rust, ruby, java, swift, deno, bun, zig, elixir, erlang

**Plugin-based:** kotlin, scala, php, lua, perl, dotnet, dart, flutter, nim, crystal, julia, clojure

## Package Managers

```bash
mise use -g pnpm@latest    # JS (npm alternative)
mise use -g uv@latest      # Python (pip alternative)
mise use -g maven@3        # Java
mise use -g gradle@latest  # Java
```

## Java Vendors

```bash
mise use java@zulu-21      # Azul Zulu
mise use java@temurin-21   # Eclipse Temurin
mise use java@corretto-21  # Amazon Corretto
```

## When Runtime Missing

If command fails with "not found":

```bash
# 1. Check if mise has it
mise search <runtime>

# 2. Install
mise use -g <runtime>@<version>

# 3. Retry original command
```

## Config

Global: `~/.config/mise/config.toml`
Project: `mise.toml` or `.tool-versions`

## Notes

- `rust (symlink)`: mise links to rustup. Use rustup for rust management.
- Some brew packages depend on brew-installed runtimes. Check with `brew uses --installed <pkg>` before removing.
