What you were trying to do (and why)

I was trying to install custom formula with custom options. Actually, I found this issue on a formula with decent amount of options, but it can be reproduced with much smaller formula (basically, took it from the cookbook).

class Foo < Formula
  desc ""
  homepage ""
  url "https://example.com/foo-0.1.tar.gz"
  sha256 "85cc828a96735bdafcf29eb6291ca91bac846579bcef7308536e0c875d6c81d7"

  # depends_on "cmake" => :build

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

  if build.with? "ham"
    puts ">>> with-ham"
  else
    puts ">>> without-ham"
  end

  def install
    # ENV.deparallelize
    system "./configure", "--disable-debug",
                          "--disable-dependency-tracking",
                          "--disable-silent-rules",
                          "--prefix=#{prefix}"
    # system "cmake", ".", *std_cmake_args
    system "make", "install"
  end

  test do
    system "false"
  end
end

What happened (include command output)

$ brew install Foo.rb --with-ham

Command output

$ brew install Foo.rb --with-ham

>>> without-ham

>>> without-ham

curl: (22) The requested URL returned error: 404

Error: An exception occurred within a child process:

DownloadError: Failed to download resource "Foo"

Download failed: https://example.com/foo-0.1.tar.gz
  

What you expected to happen

Option --with-ham should lead to >>> with-ham in the logs instead of >>> without-ham.

Step-by-step reproduction instructions (by running brew commands)

1. save provided formula somewhere
2. brew install Foo.rb --with-ham
3. Check the logs.

This doesn't repeat on the stable version, so I had to disable auto update and reset to the latest master.

Option --with-ham should lead to >>> with-ham in the logs instead of >>> without-ham.

if build.with? "ham" only works as expected inside methods e.g. def install. This is a known issue with options that is a WONTFIX.

[Boris Buliga]

But it worked up until the latest changes in master.

Is there a way to conditionally install a patch?

[Mike McQuaid]

@d12frosted Can you narrow it down to a specific commit? Can you see if build.with? behaves as expected in install?

If you can submit a PR that would be best but can consider reopening with more information. Thanks!

[Boris Buliga]

Sure, I've found an offending commit: 66ac96a. If I revert it, everything works.

Regarding the install section it doesn't work on the latest HEAD as well:

class Foo < Formula
  desc ""
  homepage ""
  url "https://ftp.gnu.org/gnu/emacs/emacs-26.3.tar.xz"
  sha256 "4d90e6751ad8967822c6e092db07466b9d383ef1653feb2f95c93e7de66d3485"

  # depends_on "cmake" => :build

  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

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

      
    # ENV.deparallelize
    system "./configure", "--disable-debug",
                          "--disable-dependency-tracking",
                          "--disable-silent-rules",
                          "--prefix=#{prefix}"
    # system "cmake", ".", *std_cmake_args
    system "make", "install"
  end

  test do
    system "false"
  end
end

Output:

$ brew install Foo.rb --with-ham

Do not report this issue to Homebrew/brew or Homebrew/core!

As you can see, in both cases it's without-ham.

Should I just update this issue or open a new one? Or maybe two? :)

Thanks for the clarification! CC @GauthamGoli FYI
