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}"

.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  rebuild 1 # Marks the old bottle as outdated without bumping the version/revision of the formula.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.

.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

: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 "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"

Parameters:

.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:

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.

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

Parameters:

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

  installed.select { |f| f.installed_alias_path == alias_path }
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:

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

.license(args = nil) ⇒ nil, ...

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" },
]

.link_overwrite(*paths) ⇒ Set<String>

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.

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:

.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.

Example

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

Parameters:

  end).uniq.sort, T.nilable(T::Array[String]))
end

.needs(*standards) ⇒ void

This method returns an undefined value.

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.

Parameters:

.on_system_blocks_exist? ⇒ 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.

Whether this formula contains OS/arch-specific blocks (e.g. on_macos, on_arm, on_monterey :or_older, on_system :linux, macos: :big_sur_or_newer).

Returns:

  • (Boolean)

# File 'formula.rb', line 3451

def on_system_blocks_exist? = !!@on_system_blocks_exist

.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.

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).

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'"

option :universal

Parameters:

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

.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:

end

.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:

  • only_if (Symbol, nil) (defaults to: nil)
  • block (T.proc.params(arg0: T.untyped).returns(T.any(T::Boolean, Symbol)), nil)

.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:

  end
end

.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.

Example

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

    spec.resource(name, klass, &block) unless spec.resource_defined?(name)
  end
end

.revision(val = T.unsafe(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) (defaults to: T.unsafe(nil))

Returns:

  • (Integer, nil)

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

.service(&block) ⇒ T.proc.returns(T.untyped)?

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:

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

Returns:

  • (T.proc.returns(T.untyped), nil)

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 3713

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) ⇒ T.untyped

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(T.untyped))

Returns:

  • (T.untyped)

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

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

Returns:

# File 'formula.rb', line 3744

def url(val = T.unsafe(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:



3995
3996
3997
 
# File 'formula.rb', line 3995

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:



3758
 
# File 'formula.rb', line 3758

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

.version_scheme(val = T.unsafe(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) (defaults to: T.unsafe(nil))

Returns:

  • (Integer, nil)

3706
 
# File 'formula.rb', line 3704

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

#generate_completions_from_executable(*commands, base_name: nil, shells: [:bash, :zsh, :fish], shell_parameter_format: nil) ⇒ void

This method returns an undefined value.

Generate shell completions for a formula for bash, zsh, fish, and optionally pwsh using the formula's executable.

Examples

Using default values for optional arguments.

generate_completions_from_executable(bin/"foo", "completions")

# translates to
(bash_completion/"foo").write Utils.safe_popen_read({ "SHELL" => "bash" }, bin/"foo", "completions", "bash")
(zsh_completion/"_foo").write Utils.safe_popen_read({ "SHELL" => "zsh" }, bin/"foo", "completions", "zsh")
(fish_completion/"foo.fish").write Utils.safe_popen_read({ "SHELL" => "fish" }, bin/"foo",
                                                         "completions", "fish")

If your executable can generate completions for PowerShell, you must pass ":pwsh" explicitly along with any other supported shells. This will pass "powershell" as the completion argument.

generate_completions_from_executable(bin/"foo", "completions", shells: [:bash, :pwsh])

# translates to
(bash_completion/"foo").write Utils.safe_popen_read({ "SHELL" => "bash" }, bin/"foo", "completions", "bash")
(pwsh_completion/"foo").write Utils.safe_popen_read({ "SHELL" => "pwsh" }, bin/"foo",
                                                          "completions", "powershell")

#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:



942
 
# File 'formula.rb', line 942

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.

#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

#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", ".", *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"
