From the discussion (macports-dev -- MacPorts developer discussion).

You can use the following command to check the script (runs the latest revision):

/bin/bash -c "$(curl -fsSL https://gist.githubusercontent.com/dive/c4a51179aa96d229a32dd3492e5fdc2d/raw/install_macports.sh)"

So far, I use the following piece of code to install MacPorts and the packages I need:

macports () {
    /bin/bash -c "$(curl -fsSL https://gist.githubusercontent.com/dive/c4a51179aa96d229a32dd3492e5fdc2d/raw/install_macports.sh)"
    PORTS=( git gh fzf ripgrep shfmt shellcheck speedtest-cli glances fswatch aria2 \
            coreutils cmake carthage xcodes rbenv )
    for PORT in "${PORTS[@]}"; do
        sudo port -N -q install "$PORT"
    done
}

Todo

• Check that port is already installed and suggest using the sudo port -v selfupdate command or uninstall first
• macOS code-names have to be normalised/removed from the download URLs
• Run sudo port selfupdate after the installation?
• Quick actions to update the $PATH for shells?

Problems

• PATH was not modified as expected for zsh

Examples

Installation example with the -store option for the installer:

% sh install.sh
Temp Path: /var/folders/gn/8j0pyrwj5j3ggxprkczkpwtc0000gn/T/macports.nziqozsB.pkg
MacPorts version: 2.7.0
macOS version: 11.3.1 (11)

installer: Note: running installer as an admin user (instead of root) gives better Mac App Store fidelity
installer: Warning: macports.nziqozsB.pkg was signed with a certificate that is not valid for store submission.
