Komac

Komac: Smart Manifest Automation for WinGet

A fast, intelligent CLI to create and submit WinGet manifests.
Think: automation, deep installer analysis, and zero YAML wrangling.

⚡ Quick start

# 1. Install komac
winget install komac
  
# 2. Set your GitHub token
komac token add
  
# 3. Update a package
komac update Package.Identifier --version 1.2.3 --urls https://example.com/installer.exe

🎯 Features

• 🔄 Advanced installer analysis
  • Inno Setup
  • Nullsoft Scriptable Install System
  • MSI
  • Burn
• 🌍 Cross-platform support (Windows, Linux, macOS)

Installation

Komac is cross-platform and binaries are built for Windows, Linux, and macOS.

All platforms

If you have cargo installed, you can compile Rust for any platform:

cargo install --locked komac

By default, komac builds with native-tls. On Linux, this builds OpenSSL and requires a C compiler, perl (and perl-core), and make. For specific dependencies, see openssl/#automatic.

Alternatively, komac can be built with rustls:

cargo install --locked --no-default-features --features rustls komac

Cargo Binstall

Komac also supports cargo-binstall:

cargo binstall komac

Nightly

Nightly releases that are built every week are available here. These are useful for debugging or if you want the latest features and fixes.

Windows

Both portable EXEs and installers are available from the releases.

WinGet

winget install komac

Scoop

scoop install komac

Linux

Portable binaries are available from the releases. Debian (.deb)and Red Hat (.rpm) installers are also available.

macOS

Portable binaries for macOS are available from the releases.

Homebrew

brew install komac

GitHub Token Setup

komac needs a classic GitHub token to submit PRs to winget-pkgs.

This should be a classic token with the public_repo scope.

Adding to komac:

komac token add

The token can be also be obtained using the GitHub CLI:

komac token add --token=$(gh auth token)

Why not fine-grained tokens?

Whilst Komac can fully create manifests and commit with a fine-grained token, it fails to create a pull request to winget-pkgs. This may change as fine-grained tokens improve. See https://github.com/russellbanks/Komac/issues/310.

Feature Comparison 🔍

While other manifest creation tools have made a solid foundation for the manifests in winget-pkgs, their development pace is slower and lacks the deeper installer analysis that komac is capable of.

[^1]: Telemetry is enabled by default in WingetCreate. Use wingetcreate settings to manually disable telemetry. [^2]: There is much more accurate detection for Inno, Nullsoft, and Burn installers since Komac v2. [^3]: The logic for this was contributed by me :) Check issues that I’ve opened to request this feature for YamlCreate.

GitHub Actions 🌟
