applecrate: A Python package for creating macOS installer packages.

AppleCrate

Package your command line tools into a native macOS installer.

AppleCrate is a tool for creating native macOS installers for your command line tools. It's useful for creating installers for command line tools written in any language. Tools written in interpreted languages like Python will need to be first processed with a tool like pyinstaller to create a standalone executable.

Installation

pip install applecrate

Simple Example

applecrate build \
--app mytool \
--version 1.0.0 \
--license LICENSE \
--install dist/mytool "/usr/local/bin/{{ app }}-{{ version }}" \
--link /usr/local/bin/mytool "/usr/local/bin/{{ app }}-{{ version }}"

This will create a native macOS installer for the tool dist/mytool which will install it to /usr/local/bin/mytool-1.0.0. The installer will create a symlink to the tool at /usr/local/bin/mytool and will also create an uninstaller to remove the tool.

How It Works

AppleCrate is a Python application that uses the pkgbuild and productbuild command line tools to create a macOS installer package. AppleCrate does not do anything that you couldn't do yourself with these tools, but it automates the process and provide a simple command line interface. Creating a macOS installer package is a multi-step process that requires the generation of multiple files such as HTML files for the welcome screen, pre and post install scripts, Distribution XML file, etc. AppleCrate takes care of all of this for you but also allows you to customize the installer by providing your own files for these steps.

AppleCrate uses Jinja2 templates to generate the files required for the installer. This allows you to use template variables in your files or command line parameters to customize the installer. For example, you can use {{ app }} and {{ version }} in your files to refer to the app name and version you provide on the command line.

  -c, --conclusion FILE           Path to conclusion markdown or HTML file
  -u, --uninstall FILE            Path to uninstall script; if not provided, an
                                  uninstall script will be created for you.See
                                  also '--no-uninstall'
  -U, --no-uninstall              Do not include an uninstall script in the

  -L, --url NAME URL              Links to additional resources to include in
                                  conclusion HTML shown after installation. For
                                  example, the project website or documentation.
  -b, --banner FILE               Path to optional PNG banner image for
                                  installer package.
  -i, --install FILE_OR_DIR DEST  Install FILE_OR_DIR to destination DEST; DEST
                                  must be an absolute path, for example
                                  '/usr/local/bin/app'. DEST may include
                                  template variables {{ app }} and {{ version
                                  }}. For example: `--install dist/app
                                  "/usr/local/bin/{{ app }}-{{ version }}"` will
                                  install the file 'dist/app' to
                                  '/usr/local/bin/app-1.0.0' if --app=app and
                                  --version=1.0.0.
  -k, --link SRC TARGET           Create a symbolic link from SRC to DEST after
                                  installation. SRC and TARGET must be absolute
                                  paths and both may include template variables
                                  {{ app }} and {{ version }}. For example:
                                  `--link "/Library/Application Support/{{ app
                                  }}/{{ version }}/app" "/usr/local/bin/{{ app
                                  }}-{{ version }}"`
  -p, --pre-install FILE          Path to pre-install shell script; if not
                                  provided, a pre-install script will be created
                                  for you.

To Do

• Add support for signing the installer with a developer certificate
• Add support for notarizing the installer
• Add python API to create installers programmatically
• Add applecrate init command to create a TOML configuration via a wizard
• Add applecrate check command to check the configuration without building the installer
• Documentation
• Tests
