Class: Formula Abstract Private

Overview

This class is part of a private API. This class may only be used in the Homebrew/brew repository. Third parties should avoid using this class if possible, as it may be removed or changed without warning.

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!

Example

class Wget < Formula
  homepage "https://www.gnu.org/software/wget/"
  url "https://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz"
  sha256 "52126be8cf1bddd7536886e74c053ad7d0ed2aa89b4b630f76785bac21695fcd"

  def install
    system "./configure", "--prefix=#{prefix}"
    system "make", "install"

.bottle(&block) ⇒ void

This method returns an undefined value.

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  rebuild 1 # Marks the old bottle as outdated without bumping the version/revision of the formula.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.
  sha256 cellar: "/brew/Cellar", tahoe:    "ef65c759c5097a36323fa9c77756468649e8d1980a3a4e05695c05e39568967c"

end

.depends_on(dep) ⇒ void

This method returns an undefined value.

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).

Examples

: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

:no_linkage declares that the formula does not link against this dependency. It does not change when the dependency is required. All declarations of the same dependency within a spec and platform must agree on :no_linkage; stable, HEAD and different platforms may differ.

depends_on "python@3.14" => :no_linkage

On a :build dependency, such as a compiler, :no_linkage also lets an outdated installed version be used when building from source, whatever its compatibility_version.

depends_on "llvm" => [:build, :no_linkage]

: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 using --with-c++11.

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

If a dependency is only needed in certain cases:

depends_on xcode: :build # If the formula really needs full Xcode to compile.
depends_on macos: :sequoia # Needs at least macOS Sequoia (15) to run.
on_tahoe :or_newer do
  depends_on "sqlite"
end

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

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

Parameters:

.deprecate!(date:, because:, replacement: nil, replacement_formula: nil, replacement_cask: nil) ⇒ void

TODO:

replace legacy replacement with replacement_formula or replacement_cask

This method returns an undefined value.

.fails_with(compiler, &block) ⇒ void

This method returns an undefined value.

Marks the Formula as failing with a particular compiler so it will fall back to others.

Examples

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

Parameters:

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

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. Git repositories must always specify branch:.

Example

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

.inherited(child) ⇒ void

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

This method returns an undefined value.

Initialise instance variables for each subclass. These need to be initialised before the class is frozen, and some DSL may never be called so it can't be done lazily.

end

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

This method returns an undefined value.

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.

Examples

keg_only :provided_by_macos
keg_only :versioned_formulae
keg_only "because I want it so"

Parameters:

4994
4995
# File 'formula.rb', line 4993

  @keg_only_reason = T.let(KegOnlyReason.new(reason, explanation), T.nilable(KegOnlyReason))
end

.license(args = nil) ⇒ SPDX::LicenseExpression?

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 formula can be licensed under later versions of the same license.

Examples

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" }
license :public_domain
license any_of: [
  "MIT",
  :public_domain,
  all_of: ["0BSD", "Zlib", "Artistic-1.0+"],
  "Apache-2.0" => { with: "LLVM-exception" },
]

Permit overwriting certain files while linking.

Examples

Sometimes we accidentally install files outside the 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-*"

Parameters:

end

.livecheck(&block) ⇒ T.untyped

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.

Example

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

Parameters:

  • block (T.proc.bind(Livecheck).returns(T.untyped), nil)

Returns:

  • (T.untyped)

.mirror(val) ⇒ void

This method returns an undefined value.

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.

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

This method returns an undefined value.

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.

Examples

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'"

Parameters:

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

This method returns an undefined value.

External patches can be declared using resource-style blocks.

Examples

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, "..."

Parameters:

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

This method returns an undefined value.

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

Examples

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

Parameters:

Raises:

.preserve_rpath(value: true) ⇒ Boolean

Preserve @rpath install names when fixing dynamic linkage on macOS.

By default, Homebrew rewrites library install names (including those starting with @rpath) to use absolute paths. This can break tools like macdeployqt that expect @rpath-based install names to remain unchanged.

Call this method to skip rewriting install names that start with @rpath.

Example

preserve_rpath

Parameters:

  • value (Boolean) (defaults to: true)

Returns:

  • (Boolean)

end

.preserve_rpath? ⇒ Boolean

This method is part of an internal API. This method may only be used internally in repositories owned by Homebrew, except in casks or formulae. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Check if @rpath install names should be preserved.

Returns:

  • (Boolean)

.pypi_packages(package_name: nil, extra_packages: nil, exclude_packages: nil, dependencies: nil) ⇒ void

This method returns an undefined value.

Adds information about PyPI formula mapping as PypiPackages object. It provides a way to specify package name in PyPI repository, define extra packages, or remove them (e.g. if formula installs them as a dependency).

Examples of usage:

# It will use information about the PyPI package `foo` to update resources
pypi_packages package_name: "foo"

Add "extra" packages and remove unneeded ones
depends_on "numpy"

pypi_packages extra_packages: "setuptools", exclude_packages: "numpy"

# Special case: empty `package_name` allows to skip resource updates for non-extra packages
pypi_packages package_name: "", extra_packages: "setuptools"

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

This method returns an undefined value.

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. Pass :test as the second argument for resources only needed by test. These are fetched by brew fetch --test or before the test sandbox starts.

Example

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

def resource(name, klass = Resource, &block)
  specs.each do |spec|
    spec.resource(name, klass, &block) unless spec.resource_defined?(name)
  end
end

.revision(val = nil) ⇒ Integer?

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.

Example

revision 1

Parameters:

  • val (Integer, nil) (defaults to: nil)

Returns:



4372
4373

# File 'formula.rb', line 4372

def revision(val = nil)
  val.nil? ? @revision : @revision = T.let(val, T.nilable(Integer))
end

.service(&block) ⇒ T.proc.void?

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 service file.

Example

service do
  run [opt_bin/"foo"]
end

Parameters:

Returns:

  • (T.proc.void, nil)

end

.service? ⇒ Boolean

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Checks whether a service specification is defined or not.

It returns true when a service block is present in the Formula and false otherwise.

Returns:

  • (Boolean)

4339
# File 'formula.rb', line 4337

def service?
  @service_block.present?
end

.sha256(val) ⇒ void

This method returns an undefined value.

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.

Example

sha256 "2a2ba417eebaadcb4418ee7b12fe2998f26d6e6f7fda7983412ff66a741ab6f7"

Parameters:

# File 'formula.rb', line 4497

def sha256(val) = stable.sha256(val)

.skip_clean(*paths) ⇒ Set<String, Symbol>

Skip cleaning paths in a formula.

Sometimes the formula cleaner breaks things.

Examples

Preserve cleaned paths with:

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

Keep .la files with:

skip_clean :la

Parameters:

Returns:

# File 'formula.rb', line 4419

def specs
  spec_syms.map do |sym|
    send(sym)
  end.freeze
end

.stable(&block) ⇒ T.untyped

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

Example

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

end

.test(&block) ⇒ void

This method returns an undefined value.

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.

Examples

(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.

Parameters:

  • block (T.proc.returns(BasicObject))

See Also:

# File 'formula.rb', line 5069

def test(&block) = define_method(:test, &block)

.url(val = nil, specs = {}) ⇒ String

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

  • :git, :hg, :svn, :fossil, :cvs,
  • :curl (normal file download, will also extract)
  • :homebrew_curl (use brewed curl)
  • :nounzip (without extracting)
  • :post (download via an HTTP POST request)

Examples

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",
    revision: "db8e4de5b2d6653f66aea53094624468caad15d2"

Parameters:

  • val (String, nil) (defaults to: nil)
  • specs (Hash{Symbol => T.anything}) (defaults to: {})

Returns:



4450
# File 'formula.rb', line 4450

def url(val = nil, specs = {}) = stable.url(val, specs)

.uses_from_macos(dep, bounds = {}) ⇒ void

This method returns an undefined value.

Indicates use of dependencies provided by macOS. On macOS this is a no-op (as we use the provided system libraries) unless :since specifies a minimum macOS version. On Linux this will act as depends_on.

Parameters:



4792
4793
4794
# File 'formula.rb', line 4792

def uses_from_macos(dep, bounds = {})
  specs.each { |spec| spec.uses_from_macos(dep, bounds) }
end

.version(val = nil) ⇒ Version?

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.

Example

version "1.2-final"

Parameters:

  • val (String, nil) (defaults to: nil)

Returns:



4464
# File 'formula.rb', line 4464

def version(val = nil) = stable.version(val)

.version_scheme(val = nil) ⇒ Integer?

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.

Example

version_scheme 1

Parameters:

  • val (Integer, nil) (defaults to: nil)

Returns:



4392
4393
4394
# File 'formula.rb', line 4392

def version_scheme(val = nil)
  val.nil? ? @version_scheme : @version_scheme = T.let(val, T.nilable(Integer))
end

#brew(fetch: true, keep_tmp: false, debug_symbols: false, interactive: false, staging_path: nil, staged: false, &_blk) ⇒ void

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

This method returns an undefined value.

Yields |self,staging| with current working directory set to the uncompressed tarball where staging is a Mktemp staging context. With staging_path, the tarball is uncompressed into that directory rather than a fresh temporary one and, with staged, its already uncompressed and patched contents are reused so the fetch and build phases share it.

Parameters:

  • fetch (Boolean) (defaults to: true)
  • keep_tmp (Boolean) (defaults to: false)
  • debug_symbols (Boolean) (defaults to: false)
  • interactive (Boolean) (defaults to: false)
  • staging_path (Pathname, nil) (defaults to: nil)
  • staged (Boolean) (defaults to: false)
  • _blk (T.proc.params(arg0: Formula, arg1: Mktemp).void)

#ensure_installed!(reason: "", latest: false, output_to_stderr: true, quiet: false, executable: nil, version_args: ["--version"]) ⇒ T.self_type, Pathname

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Ensure the given formula is installed. This is useful for installing a utility formula (e.g. shellcheck for brew style). When executable is provided, a matching system executable in ORIGINAL_PATHS can satisfy the request without installing the formula. When latest is true, the system executable's version is checked with version_args first. Returns the executable path if executable is provided, otherwise the formula.

Parameters:

  • reason (String) (defaults to: "")
  • latest (Boolean) (defaults to: false)
  • output_to_stderr (Boolean) (defaults to: true)
  • quiet (Boolean) (defaults to: false)
  • executable (String, nil) (defaults to: nil)

#env(*args, &block) ⇒ T.untyped

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Parameters:

  • args (T.untyped)
  • block (T.untyped)

Returns:

  • (T.untyped)


97
# File 'sorbet/rbi/dsl/formula.rbi', line 97

def env(*args, &block); end

#etc ⇒ Pathname

The directory where the formula's configuration files should be installed. Anything using etc.install will not overwrite other files on e.g. upgrades but will write a new file named *.default. This directory is not inside the HOMEBREW_CELLAR so it persists across upgrades.

Returns:



1409
# File 'formula.rb', line 1409

def etc = (HOMEBREW_PREFIX/"etc").extend(InstallRenamed)

#fetch ⇒ void

This method returns an undefined value.

Downloads what #install needs from the network, e.g. with a language package manager, before building from source. It runs after the source has been unpacked and patched into #buildpath, with the same build environment as #install and with network access, and may write to #buildpath and the package manager caches in HOMEBREW_CACHE. When it is defined, #install runs in the same #buildpath without network access and with the rest of HOMEBREW_CACHE read-only, so it must use the package manager's offline mode. brew fetch --build-from-source also runs it once the dependencies are installed. It is never run when installing a bottle.

Example

def fetch
  system "cargo", "fetch", *std_cargo_fetch_args
end

def install
  system "cargo", "install", *std_cargo_args

#include ⇒ Pathname

The directory where the formula's headers should be installed. This is symlinked into HOMEBREW_PREFIX after installation or with brew link for formulae that are not keg-only.

Example

No make install available?

include.install "example.h"

Returns:



1175
# File 'formula.rb', line 1175

def include = prefix/"include"

#info ⇒ Pathname

The directory where the formula's info files should be installed. This is symlinked into HOMEBREW_PREFIX after installation or with brew link for formulae that are not keg-only.

Returns:



1183
# File 'formula.rb', line 1183

def info = share/"info"

#inreplace(paths, before = nil, after = nil, audit_result: true, global: true, &block) ⇒ void

This method returns an undefined value.

Sometimes we have to change a bit before we install. Mostly we prefer a patch, but if you need the prefix of this formula in the patch you have to resort to inreplace, because in the patch you don't have access to any variables defined by the formula, as only HOMEBREW_PREFIX is available in the embedded patch.

Examples

inreplace supports regular expressions:

inreplace "somefile.cfg", /look[for]what?/, "replace by #{bin}/tool"

inreplace supports blocks:

inreplace "Makefile" do |s|
  s.gsub! "/usr/local", HOMEBREW_PREFIX.to_s
end

end

#install ⇒ void

This method returns an undefined value.

This method is overridden in Formula subclasses to provide the installation instructions. The sources (from url) are downloaded, hash-checked and then Homebrew changes into a temporary directory where the archive is unpacked or repository cloned.

Example

def install
  system "./configure", "--prefix=#{prefix}"
  system "make", "install"
end

#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.

Examples

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", "-S", ".", "-B", "build", *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"
