For the pkl CLI, please provide an installer package for Homebrew

[ujay68]

Subject says all.

Homebrew (https://brew.sh/) is a very popular package manager for macOS where you can find almost any tool you might ever want to install.

[stackoverflow]

We already started the process of releasing Pkl to homebrew. Should come soon.

Submitted here: Homebrew/homebrew-core#161655

Looks like we need to re-submit as a cask.

[ujay68]

Great. Thank you!

I don't think cask is the right approach, something like the below should work

class Pkl < Formula
  desc "Configuration as code language with rich validation and tooling"
  homepage "https://pkl-lang.org"
  url "https://github.com/apple/pkl/archive/refs/tags/0.25.1.tar.gz"
  sha256 "f60412679a9a8a1740e81cbed89a3ca9ddc9aa2cf0c487ff8a8a9fce70c0bf4a"
  license "Apache-2.0"

  depends_on "openjdk@17" => :build

  def install
    ENV["JAVA_HOME"] = Formula["openjdk@17"].opt_prefix
    task_os = OS.mac? ? "mac" : "linux"
    task_arch = Hardware::CPU.arm? ? "Aarch64" : "Amd64"
    task_name = ":pkl-cli:#{task_os}Executable#{task_arch}"

    system "git", "apply", "patches/graalVm23.patch" if OS.mac? && Hardware::CPU.arm?

    system "./gradlew", task_name
    os = OS.mac? ? "macos" : "linux"
    arch = Hardware::CPU.arm? ? "aarch64" : "amd64"
    bin.install "pkl-cli/build/executable/pkl-#{os}-#{arch}" => "pkl"
  end
end

However, the problem I am having is with homebrew's shimmed cc. It is expecting the environment variable HOMEBREW_RUBY_PATH to be present, and something is wiping out that value in the task process before the cc invocation. I tried to see where it was getting removed from the environment but was unable to figure it out

It looks like the submission has been stalled on the Homebrew side, is that the status?

there is a new submission Homebrew/homebrew-core#162857

[mattpackwood]

@pavelzw It looks like you (we) are just waiting for someone to approve the merge?

[bioball]

Yeah, right now we are waiting for a homebrew maintainer to approve and merge the PR.

This is now available on homebrew! brew install pkl will install the CLI.

We are adding instructions to our website in #270.
