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

This formula links the latest version of the Asymptote LaTeX and ConTeXt
|
|
packages into:
|
|
|
|
#{HOMEBREW_PREFIX}/share/texmf
|
|
|
|
In order for these packages to be visible to TeX compilers, the above
|
|
directory will need to be added to the TeX search path:
|
|
|
|
sudo tlmgr conf texmf TEXMFHOME "~/Library/texmf:#{HOMEBREW_PREFIX}/share/texmf"
|
|
|
|
If you wish to use xasy, you must first install the Python Imaging Library:
|
|
|
|
brew install pil
|
|
|
|
EOS
|
|
end
|
|
end
