* The python do ... end block does no longer
require 'superenv' but saves and restores
the ENV by using ENV.to_hash and `ensure`.
This should resolve some build problems
with formulae using `env :std`!
* `python_helper` is now in a module `Python`.
* Imporoved some comments in python_dependency.rb
Tokens like "b4", "beta1", "p195", &c. are now treated as atoms rather
than being broken down even further. Additionally, we enable support for
padding in the middle of versions strings, so we can successfully
compare something like "2.1-p195" with "2.1.0-p194" by inferring that
"2.1" is really "2.1.0".
This fixes the comparison "9.9.3-P1" > "9.9.3" which previously has not
been handled correctly.
This applies only to non-brewed python:
The user will still have to set his PYTHONPATH
in order to import python modules in an
external python interpreter. However, a
warning will be displayed, now.
Further, during the build, the PYTHONPATH
will be set to Homebrew's global site-packages
so that software (like PyQt and others) that
need to `import sipconfig` in python can
find the brewed sip and its python module.
Since Python has been removed from superenv and
added as an explicit `depends_on :python`,
we should add
`-F#{HOMEBREW_PREFIX}/opt/python/Framewoks`
so that build tools that don't use
`python-config --ldflags` (as they should!)
can link against brewed Python.
The depends_on 'nose' => :python
tests fails even if people did `pip install nose`
with their brewed pythons because during
the tests the PATH is set up such that
/usr/bin comes before HOMEBRE_PREFIX/bin.
This is a hot fix. Proper fix need resorting
the PATH.
Also allow to build with --HEAD by making brew's
download strategy aware of a brewed but unlined hg.
Adapted the caveats so that the procedure to brew
hg --HEAD is clear.
Mention how to config hgk in the caveats.
An "optional build-time dep" is unlikely, but possible, and I happen to
notice this wasn't handled correctly while digging around in the deps
code over the last few days.
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

open-uri on Ruby pre-1.8.6 simply will not open https URLs at all,
making it impossible to check the Github API using the same method
as Homebrew.
This may only be disabled temporarily until the issue search is
rewritten, for example to use the curl helper.
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.
