# 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!

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

# Sometimes we have to change a bit before we install. Mostly we
# prefer a patch, but if you need the {Formula#prefix 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 {DATAPatch embedded patch}.
#
# ### Examples
#
# `inreplace` supports regular expressions:
#
# ```ruby
# inreplace "somefile.cfg", /look[for]what?/, "replace by #{bin}/tool"
# ```
#
# `inreplace` supports blocks:

# ### Example
#

# @!attribute [w] head
# 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 {Patch}es 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.
#
# ### Example
#
# ```ruby
# head "https://we.prefer.https.over.git.example.com/.git"
# ```
#
# ```ruby
# head "https://example.com/.git", branch: "name_of_branch"
# ```

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

# The dependencies for this formula. Use strings for the names of other
# formulae. Homebrew provides some `:special` {Requirement}s 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.
#
# ```ruby
# depends_on "cmake" => :build
# ```
#
# `:test` means this dependency is only needed during testing.
#
# ```ruby
# depends_on "node" => :test
# ```
#
# `:recommended` dependencies are built by default.
# But a `--without-...` option is generated to opt-out.
#
# ```ruby
# depends_on "readline" => :recommended
# ```
#
# `:optional` dependencies are NOT built by default unless the
# auto-generated `--with-...` option is passed.
#
# ```ruby
# 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):
#
# ```ruby
# depends_on "zeromq" => "with-pgm"
# depends_on "qt" => ["with-qtdbus", "developer"] # Multiple options.
# ```
#
# Optional and enforce that "boost" is built using `--with-c++11`.
#
# ```ruby
# depends_on "boost" => [:optional, "with-c++11"]
# ```
#
# If a dependency is only needed in certain cases:
#
# ```ruby
# 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"`:

# 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
#
# ```ruby
# option "with-spam", "The description goes here without a dot at the end"
# ```
#
# ```ruby
# option "with-qt", "Text here overwrites what's autogenerated by 'depends_on "qt" => :optional'"

# option :universal
# ```
#
# @api public
def option(name, description = "")

# @!attribute [w] deprecated_option
# Deprecated options are used to rename options and migrate users who used
# them to newer ones. They are mostly used for migrating non-`with` options
# (e.g. `enable-debug`) to `with` options (e.g. `with-debug`).
#
# ### Example
#

# deprecated_option "enable-debug" => "with-debug"
# ```
#
# @api public

# External patches can be declared using resource-style blocks.

# sha256 "c6bc3f48ce8e797854c4b865f6a8ff969867bbcaebd648ae6fd825683e59fef2"
# end
# ```
#
# A strip level of `-p1` is assumed. It can be overridden using a symbol
# argument:
#
# ```ruby
# 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.
#
# ```ruby
# stable do
# patch do
# url "https://example.com/example_patch.diff"
# sha256 "c6bc3f48ce8e797854c4b865f6a8ff969867bbcaebd648ae6fd825683e59fef2"
# end
# end
# ```
#
# Embedded (`__END__`) patches are declared like so:
#
# ```ruby
# 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.
#
# ```ruby
# patch :p0, "..."
# ```
#
# @see https://docs.brew.sh/Formula-Cookbook#patches Patches

# Skip cleaning paths in a formula.
#
# Sometimes the formula {Cleaner cleaner} breaks things.
#
# ### Examples
#
# Preserve cleaned paths with:
#
# ```ruby
# skip_clean "bin/foo", "lib/bar"
# ```
#
# Keep .la files with:
#
# ```ruby
# skip_clean :la

#
# 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
#
# ```ruby
# keg_only :provided_by_macos
# ```
#
# ```ruby
# keg_only :versioned_formulae
# ```
#
# ```ruby
# keg_only "because I want it so"

# 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:
#
# ```ruby
# 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:
#
# ```ruby
# fails_with :gcc => '7' do
# version '7.1'
# end
# ```
#
# @api public
def fails_with(compiler, &block)
specs.each { |spec| spec.fails_with(compiler, &block) }
end
# 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`.
#
# @see .fails_with
#
# @api public
def needs(*standards)
specs.each { |spec| spec.needs(*standards) }
end
# 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
#
# ```ruby
# (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?
#
# ```ruby
# 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.
