Generating Installers

These mix tasks generate binary installers for your Elixir-Desktop project in corresponding native formats. Currently supported output formats are:

Windows: .exe installer (NSIS based)
MacOS: .dmg download package
Linux: .run makeself installer.

Usage

Add a new release to your project configuration that includes the &Desktop.Deployment.generate_installer/1 steps
Add the package: package() configuration with your app packaging information. If you don't provide these, default values will be used.
Run mix desktop.installer to generate the installer for your current OS

  def project do
    [
      package: package(),
      releases: [
        default: [
          applications: [runtime_tools: :permanent, ssl: :permanent],
          steps: [:assemble, &Desktop.Deployment.generate_installer/1]
        ],
      ],
    ]
  end

  def package() do
    [
      name: "MyApp",
      name_long: "The most wonderfull App Ever",
      description: "MyApp is an Elixir App for Desktop",
      description_long: "MyApp for Desktop is powered by Phoenix LiveView",
      icon: "priv/icon.png",
      # https://developer.gnome.org/menu-spec/#additional-category-registry
      category_gnome: "GNOME;GTK;Office;",
      category_macos: "public.app-category.productivity",
      identifier: "io.myapp.app",
    ]
  end

Installation

The the package can be installed by adding desktop_deployment to your list of dependencies in mix.exs:

def deps do
  [
    {:desktop_deployment, "~> 0.1", runtimes: false}
  ]
end

Deployment Strategies

Windows -> NSIS

All builds (specifically NIFs) are built using msys2, because it's mostly linux compatible but runs natively on windows without any helper libraries.

Installing prerequsites

msys2.org
pacman -S mingw-w64-x86_64-imagemagick mingw-w64-x86_64-nsis mingw-w64-x86_64-nsis mingw-w64-x86_64-osslsigncode mingw-w64-x86_64-openssl

mix deployment will generate the release binaries

To support windows code signing the user has to create two certificate files app_key.pem and app_key.pem (e.g. get from sectigo) and put them into the rel/win32/ subdirectory.

Known Issues / Comments

The .vbs file is used as indirection for the .bat file as it avoid creating a black terminal screen that otherwise flashes shortly when launchin a .bat file directly
The .nsis file currently registers a app:// protocol handler, this is example use and can be removed for other apps.
After having done static builds for iOS now we're thinking a pure .exe build for Windows might actually be a much cleaner solution. But TBD

MacOS -> DMG

The builds are all done on an x86_64 apple machine and we're enabling rosetta explicitly in the .plist file for M1 machines.

To run either you will need a macos development account. There are two environment variables this depends on DEVELOPER_ID which is set by build_macos.sh automatically using the default. AC_PASSWORD which is the API key for your account

build_macos.sh
notarize_macos.sh

Known Issues / Comments

Background images for the deployment window of the .dmg (when clicking that on macos) are hardcoded in the rel/macosx/ subdirectory. I've not yet discovered how to properly (dynamically) create them. Also haven't found out how to set the DMGs icon to be non-standard as some apps do.
The DMG should be notarized in two phases but right now it's not :-(
1. Notarize the app directory (by zipping and uploading it)
2. Staple the ticket to the app directory and all executables
3. Package the app directory into the dmg, notarize the dmg
4. Staple the ticket to the dmg
Best to use a really recent wxWidgets on macos, such as wxWidgets (3.1.6) as e.g. taskbar icon size bug fixes are only present there.

Linux -> makeself

Known Issues / Comments

wxWidgets notifications+taskbar support is really varying accross distributions. Currently we have a pure Elixir dbus implementation.
Getting distribution independent linux binaries is really though. Main issues have been library dependencies of different versions. Future thoughts for this:
- Switch to AppImage
- Switch to deb packages
- other?
