Answer 1 · 2020-05-14T06:59:54.000Z

it seems that build with master branch, rather than emacs-27 branch.

Answer 2 · 2020-05-14T07:02:35.000Z

Hi @shuxiao9058

It's a question to brew and not to the formula itself. As you can see, --with-emacs27-branch or --HEAD is not passed to the formula during reinstall. Normally I advise against using reinstall command at all.

(update the option name)

Answer 3 · 2020-05-14T07:11:26.000Z

Hi @shuxiao9058

It's a question to brew and not to the formula itself. As you can see, --HEAD is not passed to the formula during reinstall. Normally I advise against using reinstall command at all.

but what confused me is that it was success with reinstall before recent commit of emacs-plus.

Answer 4 · 2020-05-14T07:24:26.000Z

I don't know. It really sounds like a brew bug to me. Right now they are changing something in options parsing and it's breaking time to time (I already reported two issues during the last month).

Formula doesn't control what options are passed to it. Also, it's not formulas' responsibility to make reinstall behave like install. In my understanding if brew install formula options works, then the next brew reinstall formula must behave exactly the same as brew uninstall formula && brew install formula options. In this case it doesn't happen.

before recent commit of emacs-plus.

But brew changes also. And you are on the latest version of it. It automatically updates itself unless you explicitly disable automatic updates.

I will try to come up with simpler reproducible scenario for this issue to see if it's really brew or emacs-plus.

Let me analyse the output (it's mostly thinking out loud).

==> Checking out branch master

Already on 'master'

Your branch is up to date with 'origin/master'.

If you just install, it says that emacs-27 branch is checkout out instead of master.

I don't see --HEAD here 😿

Errno::ENOENT: No such file or directory @ rb_sysopen - /Users/jiya/Library/Caches/Homebrew/downloads/8bd90da21a7a4fcdb5c6efbf8c021fc8e894bf1675f6b5b2173af09f3ffa78b1--xwidgets_webkit_in_cocoa-emacs-27.patch

Inspecting which resources are downloaded is also interesting. It didn't download xwidgets patch, but checked for all icons and multicolor-fonts.patch, which is available only on Emacs 26.

  if build.with? "multicolor-fonts"
    unless build.head?
      patch do
        url (PatchUrlResolver.url "multicolor-fonts")
        sha256 "7597514585c036c01d848b1b2cc073947518522ba6710640b1c027ff47c99ca7"
      end
    end
  end

It really looks like reinstall messes up options.

Answer 5 · 2020-05-14T07:29:28.000Z

~~Wow, while trying to setup a new formula to reproduce this bug I've noticed that options parsing is broken again...~~ ah, I was on the broken version of brew.

Answer 6 · 2020-05-14T07:35:00.000Z

Ok, found an easy way to reproduce.

class Foo < Formula
  desc "Search tool like grep, but optimized for programmers"

  url "https://beyondgrep.com/ack-v3.3.1"
  sha256 "e4fd286d5a56f459147d562660d2f8bc4548f2f1e2d8cf3a5265b70beedbfc87"

  option "with-ham", "Description of the option"
  option "without-spam", "Another description"

  if build.with? "ham"
    puts "[pre] with-ham"
  else
    puts "[pre] without-ham"
  end

  if build.with? "spam"
    puts "[pre] with-spam"
  else
    puts "[pre] without-spam"
  end

  def install
    if build.with? "ham"
      puts "[install] with-ham"
    else
      puts "[install] without-ham"
    end

    if build.with? "spam"
      puts "[install] with-spam"
    else
      puts "[install] without-spam"
    end

    bin.install "ack-v#{version.to_s.tr("-", "_")}" => "ack"
  end

  test do
    system "true"
  end
end

Save it as Foo.rb and then:

$ brew install Foo.rb --with-ham --without-spam

As you can see, first it enters the formula with the default options (no ham but with spam) and then only it gets to the right ones (with ham and no spam).

Answer 7 · 2020-05-14T07:41:57.000Z

but what confused me is that it was success with reinstall before recent commit of emacs-plus.

In order to report this issue, I need to find which commit has broken desired behaviour. I never use reinstall (and I advise against it whenever I have a chance), so don't know when it broke. I've tried to move back in the brew history a little bit, but I still get this behaviour:

[pre] without-ham
[pre] with-spam

I am already running out of time, so won't be able to look into this issue until evening/next morning, sorry. Best what I can tell now - stop using reinstall :) brew doesn't like when formula has many options and they are making it harder and harder to maintain formula like emacs-plus, which is beefed with multiple options (that's why I am actually working on decreasing amount of options).

but what confused me is that it was success with reinstall before recent commit of emacs-plus.

Thanks for your advice, without reinstall it build and install success.

No problem 😸 I am happy that in the end you have your Emacs with desired options! 💯 This is what I care about 😸

@d12frosted very nice explanation of how the reinstall option works. The only way I found to overcome this issue is to unconditionally download all od the patches declaring them as resources. Please have a look to daviderestivo/homebrew-emacs-head@f03b7c9.

Answer 11 · 2020-05-31T11:56:19.000Z

@daviderestivo interesting. Maybe we should repeat this trick here as well 🤔

As you can see, first it enters the formula with the default options (no ham but with spam) and then only it gets to the right ones (with ham and no spam).

Inspecting which resources are downloaded is also interesting. It didn't download xwidgets patch, but checked for all icons and multicolor-fonts.patch, which is available only on Emacs 26.

So downloading all patches unconditionally really fixes this issue.

I don't see --HEAD here 😿

==> Checking out branch master
Already on 'master'
Your branch is up to date with 'origin/master'.

On the other hand, I am not sure that it will ever fix the --HEAD option.

Yes, at leat it seems to me that nothing is missing ...

On the other hand, I am not sure that it will ever fix the --HEAD option.

I went through the home-brew docs and I found this. So, in short, it seems that the --HEAD is not officially supported by the reinstall option. We could ask homebrew core team the reason why it's not supported but I guess it would be complicated to ask them to introduce it ...

Thanks for the link. I think, maybe it's a good idea breaking the package into three (I think I've already shared this idea somewhere). Maybe I will prepare a PR this week just to take a look.

Yes. I agree as well this is the best approach otherwise the number of combination option would become easily unmanageable.
