Flake References

# GitHub

mise install "nix:hello@nixos/nixpkgs#hello"

# GitLab
mise install "nix:mytool@gitlab+group/project"

# Git URLs
mise install "nix:hello@git+https://github.com/nixos/nixpkgs.git"

Local Flakes

export MISE_NIX_ALLOW_LOCAL_FLAKES=true
mise install "nix:mytool@./my-project"

VSCode Extensions

mise install "nix:vscode+install=vscode-extensions.golang.go"

JetBrains Plugins

Install plugins from the nix-jetbrains-plugins repository:

# Install File Watchers plugin for IntelliJ IDEA Ultimate (Linux)
mise install "nix:jetbrains+install=jetbrains-plugins.x86_64-linux.idea-ultimate.2024.3.com.intellij.plugins.watcher"

# Install File Watchers plugin for IntelliJ IDEA Ultimate (macOS)
mise install "nix:jetbrains+install=jetbrains-plugins.aarch64-darwin.idea-ultimate.2024.3.com.intellij.plugins.watcher"

# Install GitToolBox for GoLand
mise install "nix:jetbrains+install=jetbrains-plugins.x86_64-linux.goland.2024.3.zielu.gittoolbox"

# Install Database Tools for WebStorm
mise install "nix:jetbrains+install=jetbrains-plugins.x86_64-linux.webstorm.2024.3.com.intellij.database"

The plugin will be automatically extracted to the correct JetBrains IDE plugin directory. Restart your IDE to activate the installed plugins.

Notes:

• The system architecture (e.g., x86_64-linux, aarch64-darwin) must match your current system
• Plugins are built directly from the nix-jetbrains-plugins flake repository without querying nixhub
• You can find plugin IDs at the bottom of JetBrains Marketplace pages

Limitations

Use github+ instead of github: due to mise parsing limitations.
