Overview

This class is abstract.

A formula provides instructions and metadata for Homebrew to install a piece of software. Every Homebrew formula is a Formula. All subclasses of Formula (and all Ruby classes) have to be named UpperCase and not-use-dashes. A formula specified in this-formula.rb should have a class named ThisFormula. Homebrew does enforce that the name of the file and the class correspond. Make sure you check with brew search that the name is free!

.bottle(*args, &block) ⇒ Object

Adds a bottle SoftwareSpec. This provides a pre-built binary package built by the Homebrew maintainers for you. It will be installed automatically if there is a binary package for your platform and you haven’t passed or previously used any options on this formula.

If you maintain your own repository, you can add your own bottle links. You can ignore this block entirely if submitting to Homebrew/homebrew-core. It’ll be handled for you by the Brew Test Bot.

bottle do
  root_url "https://example.com" # Optional root to calculate bottle URLs.
  rebuild 1 # Marks the old bottle as outdated without bumping the version/revision of the formula.
  # Optionally specify the HOMEBREW_CELLAR in which the bottles were built.

end

Homebrew maintainers aim to bottle all formulae that require compilation.

Formulae that can be installed without compilation should be tagged with:

bottle :unneeded

Formulae which should not be bottled should be tagged with:

bottle :disable, "reasons"

.head(val = nil, specs = {}, &block) ⇒ Object

Adds a head SoftwareSpec. This can be installed by passing the --HEAD option to allow installing software directly from a branch of a version-control repository. If called as a method this provides just the url for the SoftwareSpec. If a block is provided you can also add depends_on and Patches just to the head SoftwareSpec. The download strategies (e.g. :using =>) are the same as for url. master is the default branch and doesn’t need stating with a branch: parameter.

head "https://we.prefer.https.over.git.example.com/.git"
head "https://example.com/.git", branch: "name_of_branch"

or (if autodetect fails):

head "https://hg.is.awesome.but.git.has.won.example.com/", using: :hg

.license(args = nil) ⇒ Object

The SPDX ID of the open-source license that the formula uses. Shows when running brew info. Use :any_of, :all_of or :with to describe complex license expressions. :any_of should be used when the user can choose which license to use. :all_of should be used when the user must use all licenses. :with should be used to specify a valid SPDX exception. Add + to an identifier to indicate that the formulae can be licensed under later versions of the same license.

license "BSD-2-Clause"
license "EPL-1.0+"
license any_of: ["MIT", "GPL-2.0-only"]
license all_of: ["MIT", "GPL-2.0-only"]
license "GPL-2.0-only" => { with: "LLVM-exception" }

.livecheck(&block) ⇒ Object

Livecheck can be used to check for newer versions of the software. This method evaluates the DSL specified in the livecheck block of the Formula (if it exists) and sets the instance variables of a Livecheck object accordingly. This is used by brew livecheck to check for newer versions of the software.

livecheck do
  skip "Not maintained"
  url "https://example.com/foo/releases"
  regex /foo-(\d+(?:\.\d+)+)\.tar/

end

.mirror(val) ⇒ Object

Additional URLs for the stable version of the formula. These are only used if the url fails to download. It’s optional and there can be more than one. Generally we add them when the main url is unreliable. If url is really unreliable then we may swap the mirror and url.

mirror "https://in.case.the.host.is.down.example.com"
mirror "https://in.case.the.mirror.is.down.example.com

end

.option(name, description = "") ⇒ Object

Options can be used as arguments to brew install. To switch features on/off: "with-something" or "with-otherthing". To use other software: "with-other-software" or "without-foo". Note that for depends_on that are :optional or :recommended, options are generated automatically.

There are also some special options:

  • :universal: build a universal binary/library (e.g. on newer Intel Macs this means a combined x86_64/x86 binary/library).
option "with-spam", "The description goes here without a dot at the end"
option "with-qt", "Text here overwrites what's autogenerated by 'depends_on "qt" => :optional'"
option :universal

# File 'formula.rb', line 2814

def option(name, description = "")
  specs.each { |spec| spec.option(name, description) }
end

.revision=(value) ⇒ Object (writeonly)

Used for creating new Homebrew versions of software without new upstream versions. For example, if we bump the major version of a library that this Formula depends_on then we may need to update the revision of this Formula to install a new version linked against the new library version. 0 if unset.

revision 1


2574
 
# File 'formula.rb', line 2574

attr_rw :revision

.service(&block) ⇒ Object

Service can be used to define services. This method evaluates the DSL specified in the service block of the Formula (if it exists) and sets the instance variables of a Service object accordingly. This is used by brew install to generate a plist.

service do
  run [opt_bin/"foo"]
end

  return @service_block unless block

  @service_block = block
end

.sha256(val) ⇒ Object

To verify the cached download’s integrity and security we verify the SHA-256 hash matches what we’ve declared in the Formula. To quickly fill this value you can leave it blank and run brew fetch --force and it’ll tell you the currently valid value.

sha256 "2a2ba417eebaadcb4418ee7b12fe2998f26d6e6f7fda7983412ff66a741ab6f7"

2646
 
# File 'formula.rb', line 2644

def sha256(val)
  stable.sha256(val)
end

.stable(&block) ⇒ Object

Allows adding depends_on and Patches just to the stable SoftwareSpec. This is required instead of using a conditional. It is preferrable to also pull the url and sha256 into the block if one is added.

stable do
  url "https://example.com/foo-1.0.tar.gz"
  sha256 "2a2ba417eebaadcb4418ee7b12fe2998f26d6e6f7fda7983412ff66a741ab6f7"

end

.url(val, specs = {}) ⇒ Object

The URL used to download the source for the stable version of the formula. We prefer https for security and proxy reasons. If not inferrable, specify the download strategy with using: ....

  • :git, :hg, :svn, :bzr, :fossil, :cvs,
  • :curl (normal file download, will also extract)
  • :nounzip (without extracting)
  • :post (download via an HTTP POST)
url "https://packed.sources.and.we.prefer.https.example.com/archive-1.2.3.tar.bz2"
url "https://some.dont.provide.archives.example.com",
    using:    :git,
    tag:      "1.2.3",

end

.version(val = nil) ⇒ Object

The version string for the stable version of the formula. The version is autodetected from the URL and/or tag so only needs to be declared if it cannot be autodetected correctly.

version "1.2-final"

# File 'formula.rb', line 2619

def version(val = nil)

end

.version_scheme=(value) ⇒ Object (writeonly)

Used for creating new Homebrew version schemes. For example, if we want to change version scheme from one to another, then we may need to update version_scheme of this Formula to be able to use new version scheme, e.g. to move from 20151020 scheme to 1.0.0 we need to increment version_scheme. Without this, the prior scheme will always equate to a higher version. 0 if unset.

end

.depends_on(dep) ⇒ Object

The dependencies for this formula. Use strings for the names of other formulae. Homebrew provides some :special Requirements for stuff that needs extra handling (often changing some ENV vars or deciding whether to use the system provided version).

:build means this dependency is only needed during build.

depends_on "cmake" => :build

:test means this dependency is only needed during testing.

depends_on "node" => :test

:recommended dependencies are built by default. But a --without-... option is generated to opt-out.

depends_on "readline" => :recommended

:optional dependencies are NOT built by default unless the auto-generated --with-... option is passed.

depends_on "glib" => :optional

If you need to specify that another formula has to be built with/out certain options (note, no -- needed before the option):

depends_on "zeromq" => "with-pgm"
depends_on "qt" => ["with-qtdbus", "developer"] # Multiple options.

Optional and enforce that “boost” is built with --with-c++11.

depends_on "boost" => [:optional, "with-c++11"]

If a dependency is only needed in certain cases:

depends_on "sqlite" if MacOS.version >= :catalina
depends_on xcode: :build # If the formula really needs full Xcode to compile.
depends_on macos: :mojave # Needs at least macOS Mojave (10.14) to run.

It is possible to only depend on something if build.with? or build.without? "another_formula":

depends_on "postgresql" if build.without? "sqlite"

.fails_with(compiler, &block) ⇒ Object

Marks the Formula as failing with a particular compiler so it will fall back to others. For Apple compilers, this should be in the format:

fails_with :clang do
  build 600
  cause "multiple configure and compile errors"
end

The block may be omitted, and if present the build may be omitted; if so, then the compiler will not be allowed for all versions.

major_version should be the major release number only, for instance ‘7’ for the GCC 7 series (7.0, 7.1, etc.). If version or the block is omitted, then the compiler will not be allowed for all compilers in that series.

For example, if a bug is only triggered on GCC 7.1 but is not encountered on 7.2:

fails_with :gcc => '7' do
  version '7.1'
end

.keg_only(reason, explanation = "") ⇒ Object

Software that will not be symlinked into the brew --prefix and will only live in its Cellar. Other formulae can depend on it and Homebrew will add the necessary includes, libraries, and other paths while building that other formula.

Keg-only formulae are not in your PATH and are not seen by compilers if you build your own software outside of Homebrew. This way, we don’t shadow software provided by macOS.

.link_overwrite(*paths) ⇒ Object

Permit overwriting certain files while linking.

Sometimes we accidentally install files outside prefix. Once we fix that, users will get a link conflict error. Overwrite those files with:

link_overwrite "bin/foo", "lib/bar"
link_overwrite "share/man/man1/baz-*"

Returns:

  • (Boolean)

  @livecheckable == true
end

.needs(*standards) ⇒ Object

Marks the Formula as needing a certain standard, so Homebrew will fall back to other compilers if the default compiler does not implement that standard.

We generally prefer to depends_on a desired compiler and to explicitly use that compiler in a formula’s #install block, rather than implicitly finding a suitable compiler with needs.

.patch(strip = :p1, src = nil, &block) ⇒ Object

External patches can be declared using resource-style blocks.

patch do
  url "https://example.com/example_patch.diff"
  sha256 "c6bc3f48ce8e797854c4b865f6a8ff969867bbcaebd648ae6fd825683e59fef2"
end

A strip level of -p1 is assumed. It can be overridden using a symbol argument:

patch :p0 do
  url "https://example.com/example_patch.diff"
  sha256 "c6bc3f48ce8e797854c4b865f6a8ff969867bbcaebd648ae6fd825683e59fef2"
end

Patches can be declared in stable and head blocks. This form is preferred over using conditionals.

stable do
  patch do
    url "https://example.com/example_patch.diff"
    sha256 "c6bc3f48ce8e797854c4b865f6a8ff969867bbcaebd648ae6fd825683e59fef2"
  end
end

Embedded (__END__) patches are declared like so:

patch :DATA
patch :p0, :DATA

Patches can also be embedded by passing a string. This makes it possible to provide multiple embedded patches while making only some of them conditional.

patch :p0, "..."

.plist_options(options) ⇒ Object

Defines launchd plist handling.

Does your plist need to be loaded at startup?

plist_options startup: true

Or only when necessary or desired by the user?

plist_options manual: "foo"

Or perhaps you’d like to give the user a choice? Ooh fancy.

plist_options startup: true, manual: "foo start"

def plist_options(options)
  @plist_startup = options[:startup]
  @plist_manual = options[:manual]
end

.pour_bottle?(only_if: nil, &block) ⇒ Boolean

Defines whether the Formula’s bottle can be used on the given Homebrew installation.

For example, if the bottle requires the Xcode CLT to be installed a Formula would declare:

pour_bottle? do
  reason "The bottle needs the Xcode CLT to be installed."
  satisfy { MacOS::CLT.installed? }
end

If satisfy returns false then a bottle will not be used and instead the Formula will be built from source and reason will be printed.

Alternatively, a preset reason can be passed as a symbol:

pour_bottle? only_if: :clt_installed

Returns:

  • (Boolean)

.resource(name, klass = Resource, &block) ⇒ Object

Additional downloads can be defined as resources and accessed in the install method. Resources can also be defined inside a stable or head block. This mechanism replaces ad-hoc “subformula” classes.

resource "additional_files" do
  url "https://example.com/additional-stuff.tar.gz"
  sha256 "c6bc3f48ce8e797854c4b865f6a8ff969867bbcaebd648ae6fd825683e59fef2"

.skip_clean(*paths) ⇒ Object

Skip cleaning paths in a formula.

Sometimes the formula cleaner breaks things. Preserve cleaned paths with:

skip_clean "bin/foo", "lib/bar"

Keep .la files with:

skip_clean :la

def skip_clean(*paths)
  paths.flatten!
  # Specifying :all is deprecated and will become an error
  skip_clean_paths.merge(paths)
end

.test(&block) ⇒ Boolean

A test is required for new formulae and makes us happy. The block will create, run in and delete a temporary directory.

We want tests that don’t require any user input and test the basic functionality of the application. For example, foo build-foo input.foo is a good test and foo --version or foo --help are bad tests. However, a bad test is better than no test at all.

(testpath/"test.file").write <<~EOS
  writing some test file, if you need to
EOS
assert_equal "OK", shell_output("test_command test.file").strip

Need complete control over stdin, stdout?

require "open3"
Open3.popen3("#{bin}/example", "argument") do |stdin, stdout, _|
  stdin.write("some text")
  stdin.close
  assert_equal "result", stdout.read
end

The test will fail if it returns false, or if an exception is raised. Failed assertions and failed system commands will raise exceptions.

Returns:

  • (Boolean)

#system(cmd, *args) ⇒ void

This method returns an undefined value.

To call out to the system, we use the system method and we prefer you give the args separately as in the line below, otherwise a subshell has to be opened first.

system "./bootstrap.sh", "--arg1", "--prefix=#{prefix}"

For CMake and other build systems we have some necessary defaults in e.g. #std_cmake_args:

system "cmake", ".", *std_cmake_args

If the arguments given to configure (or make or cmake) are depending on options defined above, we usually make a list first and then use the args << if <condition> to append each:

args = ["--with-option1", "--with-option2"]
args << "--without-gcc" if ENV.compiler == :clang

# Most software still uses `configure` and `make`.
# Check with `./configure --help` for what our options are.
system "./configure", "--disable-debug", "--disable-dependency-tracking",
                      "--disable-silent-rules", "--prefix=#{prefix}",
                      *args # our custom arg list (needs `*` to unpack)

# If there is a "make install" available, please use it!
system "make", "install"
