superenv: build-environments that just work 1. A minimal build environment, we don't set CFLAGS, CPPFLAGS, LDFLAGS, etc. the rationale being, the less that is set, the less variables we are introducing that can break builds. 2. A set of scripts that replace cc, ld, etc. and inject the -I, -L, etc. flags we need into the args passed to the build-tools. Because we now have complete control over compiler instantiations we do a variety of clean-up tasks, like removing bad flags, enforcing universal builds and ensuring makefiles don't try to change the order of library and include paths from ones that work to ones that don't. The previous ENV-system is still available when --env=std is specified. superenv applies to Xcode >= 4.3 only currently.

### Why `superenv`?
# 1) Only specify the environment we need (NO LDFLAGS for cmake)
# 2) Only apply compiler specific options when we are calling that compiler
# 3) Force all incpaths and libpaths into the cc instantiation (less bugs)
# 4) Cater toolchain usage to specific Xcode versions
# 5) Remove flags that we don't want or that will break builds
# 6) Simpler code
# 7) Simpler formula that *just work*
# 8) Build-system agnostic configuration of the tool-chain

attr_accessor :keg_only_deps, :deps, :x11
superenv only adds X11 paths if required Since we are moving towards only depending on X11 for X-headers, superenv now doesn't automatically add X11 compilation. I was reluctant to do this, but it is the right thing to do now that X11 is not automatically installed by OS X or Xcode. I didn't implement ENV.x11 because the order that the X headers are inserted is important. It must be done at initial setup to ensure that brewed versions of e.g. freetype and Cairo are used and not the ones installed by XQuartz.

Fix superenv ENV[] hack We override ENV[] to always return strings under superenv, because legacy formulae assume that CFLAGS, etc. are non-nil. However, the current implementation has a bug. If I simply concatenate ENV['CFLAGS'] with another string, it mutates ENV['CFLAGS']: irb> ENV['CFLAGS'] => "" irb> ENV['CFLAGS'] + 'a' => "a" irb> ENV['CFLAGS'] => "a" Instead, let's simply return an empty string if the key doesn't exist. This is sufficient because the following are equivalent: 1. ENV['CFLAGS'] += "string" 2. ENV['CFLAGS'] = ENV['CFLAGS'] + "string"

Python 2.x and 3.x support New `depends_on :python` Dependency. New `depends_on :python3` Dependency. To avoid having multiple formulae with endings -py2 and -py3, we will handle support for different pythons (2.x vs. 3.x) in the same formula. Further brewed vs. external python will be transparently supported. The formula also gets a new object `python`, which is false if no Python is available or the user has disabled it. Otherwise it is defined and provides several support methods: python.site_packages # the site-packages in the formula's Cellar python.global_site_packages python.binary # the full path to the python binary python.prefix python.version python.version.major python.version.minor python.xy # => e.g. "python2.7" python.incdir # includes of python python.libdir # the python dylib library python.pkg_config_path # used internally by brew python.from_osx? python.framework? python.universal? python.pypy? python.standard_caveats # Text to set PYTHONPATH for python.from_osx? python.if3then3 # => "" for 2.x and to "3" for 3.x. Further, to avoid code duplication, `python` takes an optional block that is run twice if the formula defines depends_on :python AND :python3. python do system python, 'setup.py', "--prefix=#{prefix}" end Read more in the Homebrew wiki.

superenv: find Homebrew's gcc-4.2 If we're using a homebrewed gcc-4.2, xcrun may fail to find it (or, worse, find superenv's shim instead). Explicitly add it to the PATH and search all path elements for the requested tool. Also make sure to specify 'gcc-4.2' as the compiler name, not plain 'gcc'. That can resolve to llvm-gcc and to gcc-4.0 on various Xcodes.

superenv: Allow ENV.m32 (for 32bit builds) Superenv normally filters out "-m32" flag, preventing 32bit builds. Some software, however, still only work in 32bit mode. If ENV.m32 is called, superenv does not filter out the "-m32" flag. Also note, superenv, does not explicitly add the -m32 flag and expects the build system of the software to know when and where to provide this flag. Closes Homebrew/homebrew#16350.

Unify compiler selection logic This unifies the logic for selecting a compiler between superenv and stdenv. A variation of superenv's `determine_cc`, which now returns a symbol, has been moved into the shared ENV extension. Stdenv uses the result of this directly (as it's always used symbols), while superenv translates that back into a compiler string. This also has the effect of disabling HOMEBREW_USE_(gcc|llvm|clang) in stdenv, which have already been marked as deprecated for some time, and enables the HOMEBREW_CC= environment variable syntax from superenv in stdenv.

Better superenv support for Xcode elsewhere - The Library/ENV/4.3/xcrun shim now respects ENV['DEVELOPER_DIR'] instead assuming the location of /Applications/Xcode.app/Contents/Developer. - The env var DEVELOPER_DIR is set if it is not already. So, during superenv this var is always set and we no longer have to care about people with unset or wrongly set xcode-select stuff. This has been a major PITA in the past. - determine_developer_dir (which is used to set the DEVELOPER_DIR var) now uses MacOS::Xcode.prefix which is proven and very capable and uses splotlight correctly. - Replace (and remove) MacSystem.xcode43_developer_dir with Xcode.prefix Closes Homebrew/homebrew#18618

Python 2.x and 3.x support New `depends_on :python` Dependency. New `depends_on :python3` Dependency. To avoid having multiple formulae with endings -py2 and -py3, we will handle support for different pythons (2.x vs. 3.x) in the same formula. Further brewed vs. external python will be transparently supported. The formula also gets a new object `python`, which is false if no Python is available or the user has disabled it.

superenv only adds X11 paths if required Since we are moving towards only depending on X11 for X-headers, superenv now doesn't automatically add X11 compilation. I was reluctant to do this, but it is the right thing to do now that X11 is not automatically installed by OS X or Xcode. I didn't implement ENV.x11 because the order that the X headers are inserted is important. It must be done at initial setup to ensure that brewed versions of e.g. freetype and Cairo are used and not the ones installed by XQuartz.

Clean up MacOS version method usage The MacOS.version? family of methods (other than "leopard?") are poorly defined and lead to confusing code. Replace them in formulae with more explicit comparisons. "MacOS.version" is a special version object that can be compared to numerics, symbols, and strings using the standard Ruby comparison methods. The old methods were moved to compat when the version comparison code was merged, and they must remain there "forever", but they should not be used in new code.

superenv: build-environments that just work 1. A minimal build environment, we don't set CFLAGS, CPPFLAGS, LDFLAGS, etc. the rationale being, the less that is set, the less variables we are introducing that can break builds. 2. A set of scripts that replace cc, ld, etc. and inject the -I, -L, etc. flags we need into the args passed to the build-tools. Because we now have complete control over compiler instantiations we do a variety of clean-up tasks, like removing bad flags, enforcing universal builds and ensuring makefiles don't try to change the order of library and include paths from ones that work to ones that don't. The previous ENV-system is still available when --env=std is specified. superenv applies to Xcode >= 4.3 only currently.

Implement fails_with for non-Apple compilers This adds support for non-Apple GCC compilers in the fails_with code. A fails_with block for a non-Apple compiler looks like: fails_with :gcc => '4.8.1' do cause 'Foo' end Non-Apple compilers don't have build numbers, so compiler failures are based on version strings instead. Internally non-Apple compilers can be distinguished because they are passed around as strings instead of symbols. In addition, this alters the priority list for compilers, with the following changes: * Apple GCC 4.2 and LLVM-GCC swap positions, with GCC now taking priority. (Maybe LLVM-GCC should just go away.) * Non-Apple GCC compilers are ranked below GCC 4.2 but above LLVM-GCC and Apple GCC 4.0.

superenv: build-environments that just work 1. A minimal build environment, we don't set CFLAGS, CPPFLAGS, LDFLAGS, etc. the rationale being, the less that is set, the less variables we are introducing that can break builds. 2. A set of scripts that replace cc, ld, etc. and inject the -I, -L, etc. flags we need into the args passed to the build-tools. Because we now have complete control over compiler instantiations we do a variety of clean-up tasks, like removing bad flags, enforcing universal builds and ensuring makefiles don't try to change the order of library and include paths from ones that work to ones that don't. The previous ENV-system is still available when --env=std is specified. superenv applies to Xcode >= 4.3 only currently.

Reference self rather than ENV in Superenv module We want to be able to extend this module onto an arbitrary hash and use it without mutating ENV, for testing purposes.

Use File::PATH_SEPARATOR globally instead of ':' On Unix, the path separator is ':', whereas on Windows, it is ';'. This is the first of a series of patch to bring macbrew's and winbrew's codebases closer together. The main places the magic constant ':' was being used were: - the $PATH environment variable - CMAKE-related environment variables - pkg-config related environment variables Closes Homebrew/homebrew#21921.
