Homebrew tap for Ladybird for macOS use, testing, etc?

[ylluminate]

It seems that pulling together a Homebrew tap for Ladybird could be attractive and improve testing and development opportunities on macOS.

agree! I'm ready as a tester

Ladybird is not ready for general user testing. If there's a way to put a package behind a "please only use it you're planning to contribute upstream" flag, them sure, we could probably help out with whoever wants to maintain a brew package.

But really, the browser is in a pre-alpha state. Exposing it to non-developer users when we have so many features unimplemented and low hanging fruit bugs around would not give a first impression we can be proud of. We would much rather the browser be tested by people who have the source code already handy to submit patches.

I suspect that a roadmap describing when a homebrew package would be appropriate will surface soon ™️.

We might be able to do something like this (I'm not a Homebrew guy; I use it out of necessity, but I'm not a fan of their project so I don't contribute to it - I prefer MacPorts, but I realize Homebrew has the market share... so take what I say below as a stab in the dark and I would expect someone else with more experience to chime in with a proper refined answer):

NOTE: I think a regularly updated tarball might be good to have for "milestone builds" - and a "build from master" option could also be implemented as a flag.

1. Create a tap with a check for an environment variable to restrict installation to developers, example:

   class Ladybird < Formula
   desc "Ladybird browser for macOS (pre-alpha developer version)"
   homepage "https://github.com/LadybirdWebBrowser/ladybird"
   url "https://github.com/LadybirdWebBrowser/ladybird/releases/download/v0.1/ladybird-milestone-0.1.tar.gz"
   version "0.1"
   sha256 "milestone_sha256_here"
   license "BSD-2-Clause"
   
   option "with-github-master", "Build from the latest GitHub master branch"
   
   depends_on "cmake" => :build
   depends_on "ninja" => :build
   depends_on "ccache" => :build
   depends_on "qt"
   depends_on xcode: ["14.3", :build]
   depends_on macos: :minimum_version_of_macos_here
   
   def install
   if ENV["LADYBIRD_DEVELOPER"] != "true"
     odie "Ladybird is in pre-alpha. Set LADYBIRD_DEVELOPER=true to install."
   end
   
   if build.with? "github-master"
     ohai "Cloning Ladybird repository"
     system "git", "clone", "--depth", "1", "https://github.com/LadybirdWebBrowser/ladybird.git"
     chdir "ladybird"
   else
     ohai "Extracting milestone tarball"
     system "tar", "xzf", "ladybird-milestone-#{version}.tar.gz"
     chdir "ladybird-milestone-#{version}"
   end
   
   mkdir "build" do
     system "cmake", "..", "-GNinja", *std_cmake_args
     system "ninja"
     system "ninja", "install"
   end
   end
   
   def caveats
   <<~EOS
     Ladybird is in pre-alpha stage and is intended for developers only.
   
     To build from the GitHub master branch:
       LADYBIRD_DEVELOPER=true brew install LadybirdWebBrowser/ladybird/ladybird --with-github-master
   
     To install the latest milestone tarball:
       LADYBIRD_DEVELOPER=true brew install LadybirdWebBrowser/ladybird/ladybird
   
     To prevent Homebrew from automatically updating this formula:
       brew pin ladybird
   
     Note: Xcode 14.3 or later is required to build Ladybird.
   
     The SHA for the milestone tarball must be updated regularly to reflect new stable builds.
   EOS
   end
   
   test do
   assert_match "Ladybird Version #{version}", shell_output("#{bin}/ladybird --version")
   end
   end

2. Developers would set the LADYBIRD_DEVELOPER variable before installation (as per instructions in the recipe); some instructions like this could be given on the website/build instructions:

   
   To install from GitHub master branch:
   LADYBIRD_DEVELOPER=true brew install LadybirdWebBrowser/ladybird --with-github-master

To install the milestone tarball by default: LADYBIRD_DEVELOPER=true brew install LadybirdWebBrowser/ladybird

To prevent automatic updates: brew pin ladybird

You can build using MacPorts. You need to make sure the same (required) packages are installed using MacPorts, and then modify Meta/CMake/lagom_compile_options.cmake from:

if (APPLE) list(APPEND CMAKE_PREFIX_PATH /opt/homebrew) endif()

To this:

if (APPLE) list(APPEND CMAKE_PREFIX_PATH /opt/local) endif()
