Installation

Alpha Software

Invowk™ is currently in alpha stage. While we strive for stability, expect breaking changes between releases as we stabilize the invowkfile format, module structure, and feature set. We recommend pinning to a specific version for production use and following the GitHub releases for migration guides.

Welcome to Invowk! Let's get you set up and running commands in no time.

Requirements

• Linux, macOS, or Windows — Invowk works on all three!

For container runtime features, you'll also need:

• Docker or Podman installed and running

Installation Methods

Shell Script

The quickest way to install on Linux or macOS:

curl -fsSL https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.sh | sh

This downloads the latest release from GitHub, verifies its SHA256 checksum, and installs to ~/.local/bin.

Customize the installation:

# Install to a custom directory
INSTALL_DIR=/usr/local/bin curl -fsSL https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.sh | sh

# Install a specific version
INVOWK_VERSION=v1.0.0 curl -fsSL https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.sh | sh

Variable	Default	Description
INSTALL_DIR	~/.local/bin	Where to install the binary
INVOWK_VERSION	latest stable	Install a specific version (e.g., v1.0.0)
GITHUB_TOKEN	unset	Optional; avoids API rate limiting

PowerShell (Windows)

The quickest way to install on Windows:

irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

This downloads the latest release from GitHub, verifies its SHA256 checksum, and installs to %LOCALAPPDATA%\Programs\invowk. Your User PATH is updated automatically.

Customize the installation:

# Install to a custom directory
$env:INSTALL_DIR='C:	oolsinvowk'; irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

# Install a specific version
$env:INVOWK_VERSION='v1.0.0'; irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

# Skip automatic PATH modification
$env:INVOWK_NO_MODIFY_PATH='1'; irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

Variable	Default	Description
INSTALL_DIR	%LOCALAPPDATA%\Programs\invowk	Where to install the binary
INVOWK_VERSION	latest stable	Install a specific version (e.g., v1.0.0)
INVOWK_NO_MODIFY_PATH	unset	Set to 1 to skip automatic PATH modification
GITHUB_TOKEN	unset	Optional; avoids API rate limiting

WinGet (Windows)

Install using WinGet on Windows 10/11:

winget install Invowk.Invowk

To upgrade later:

winget upgrade Invowk.Invowk

Homebrew

If you use Homebrew on macOS or Linux:

brew install invowk/tap/invowk

To upgrade later:

brew upgrade invowk

Go Install

If you have Go 1.26+ installed:

go install github.com/invowk/invowk@latest

The binary is installed to $GOBIN (or $GOPATH/bin).

From Source

Clone and build from source:

git clone https://github.com/invowk/invowk
cd invowk
make build

Then install to your $GOPATH/bin:

make install

Or move the binary manually:

# Linux/macOS
sudo mv invowk /usr/local/bin/

# Or add to your local bin
mv invowk ~/.local/bin/

Note: On x86-64 systems, the default build targets the x86-64-v3 microarchitecture (Haswell+ CPUs from 2013+) for optimal performance. For maximum compatibility with older CPUs, use make build GOAMD64=v1.

Verify Installation

Once installed, verify everything works:

invowk --version

You should see the version information. If you get a "command not found" error, make sure the binary is in your PATH.

Upgrading

Upgrade using the same method you used to install:

• Shell script: Re-run the install command — it downloads the latest release and overwrites the existing binary:

curl -fsSL https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.sh | sh

To upgrade to a specific version, set INVOWK_VERSION:

# Install to a custom directory
INSTALL_DIR=/usr/local/bin curl -fsSL https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.sh | sh

# Install a specific version
INVOWK_VERSION=v1.0.0 curl -fsSL https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.sh | sh

• PowerShell script: Re-run the install command — it downloads the latest release and overwrites the existing binary:

irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

To upgrade to a specific version, set INVOWK_VERSION:

# Install to a custom directory
$env:INSTALL_DIR='C:	oolsinvowk'; irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

# Install a specific version
$env:INVOWK_VERSION='v1.0.0'; irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

# Skip automatic PATH modification
$env:INVOWK_NO_MODIFY_PATH='1'; irm https://raw.githubusercontent.com/invowk/invowk/main/scripts/install.ps1 | iex

• WinGet: winget upgrade Invowk.Invowk

• Homebrew: brew upgrade invowk

• Go install: go install github.com/invowk/invowk@latest

• From source: Pull the latest changes and rebuild:

  git pull && make build && make install

eval "$(invowk completion bash)"

# Or install system-wide
invowk completion bash > /etc/bash_completion.d/invowk

Zsh

# Add to ~/.zshrc
