#
# Provide support for Python related ports. This includes detecting Python
# interpreters, ports providing package and modules for python as well as
# consumer ports requiring Python at build or run time.
#
# Feature:  python
# Usage:    USES=python or USES=python:args
# Valid ARGS:   <version>, build, run, test
#
# version   If your port requires only some set of Python versions, you
#       can set this to [min]-[max] or min+ or -max or as an
#       explicit version or as a meta port version (eg. 3.2-3.3 for
#       [min]-[max], 2.7+ or -3.2 for min+ and -max, 2.7 for an
#       explicit version or 3 for a meta port version). Example:
#
#           USES=python:2.7     # Only use Python 2.7
#           USES=python:3.2+    # Use Python 3.2 or newer
#           USES=python:3.2-3.3 # Use Python 3.2 or 3.3
#           USES=python:-3.2    # Use any Python up to 3.2
#           USES=python:2       # Use the Python 2 meta port
#           USES=python     # Use the set default Python
#                       # version
#
# build     Indicates that Python is needed at build time and adds
#       it to BUILD_DEPENDS.
# run       Indicates that Python is needed at run time and adds
#       it to RUN_DEPENDS.
# test      Indicates that Python is needed at test time and adds
#       it to TEST_DEPENDS.
#
# If build, run and test are omitted, Python will be added as BUILD_DEPENDS,
# RUN_DEPENDS and TEST_DEPENDS. PYTHON_NO_DEPENDS can be set to not add any
# dependencies.
#
# Variables, which can be set by a user:
#
# PYTHON_VERSION    - The chosen Python interpreter including the version,
#             e.g. python2.7, python3.3, etc. This allows the user
#             to override the currently chosen default version and
#             to install the port for a specific Python version.
#             It must not be set by a port.
#
# Variables, which can be set by the port:
#
# USE_PYTHON        - A list of additional features and functionality to
#             enable. Supported features are:
#
#   concurrent  - Indicates that the port can be installed for
#             different python versions at the same time. The port
#             is supposed to use a unique prefix for certain
#             directories using USES=uniquefiles:dirs (see the
#             uniquefiles.mk Uses for details about the
#             directories), if set to yes. Binaries receive an
#             additional suffix, based on ${PYTHON_VER}.
#
#             The values for the uniquefiles USES are set as
#             follows:
#
#               UNIQUE_PREFIX=  ${PYTHON_PKGNAMEPREFIX}
#               UNIQUE_SUFFIX=  -${PYTHON_VER}
#
#             If the port is installed for the current default
#             python version, scripts and binaries in
#
#               ${PREFIX}/bin
#               ${PREFIX}/sbin
#               ${PREFIX}/libexec
#
#             are linked from the prefixed version to the
#             prefix-less original name, e.g.
#             bin/foo-2.7 --> bin/foo.
#
#   distutils   - Use distutils as do-configure, do-build and
#             do-install targets.
#
#   autoplist   - Automatically generates the packaging list for a
#             port that uses distutils when defined.
#             requires: distutils
#
#   py3kplist   - Automatically generates Python 3.x compatible
#             __pycache__ entries from a Python 2.x packaging list
#             when defined. Use this for ports that do *not* use
#             standard Python packaging mechanisms such as
#             distutils, and support *both* Python 2.x and 3.x.
#             Not needed, if USE_PYTHON=autoplist is set.
#
#   pythonprefix    - Says that the port installs in ${PYTHONBASE} instead
#             of ${PREFIX}.
#
#   noegginfo   - Skip an egg-info entry from plist, if defined.
#
# PYTHON_CMD        - Python's command line file name, including the

#
# PYDISTUTILS_PKGVERSION

#
# PYDISTUTILS_INSTALL_TARGET

#
# The following variables can be read by ports and must not be modified:
#
# PYTHONBASE        - The installation prefix of the chosen Python
#             interpreter, e.g. /usr/local

#             default: ${PYTHON_LIBDIR}/site-packages
#
# There are PREFIX-clean variants of the PYTHON_*DIR variables above.
# They are meant to be used by ports instead of the above variables, so the
# ports respect ${PREFIX} (unless USE_PYTHON=pythonprefix is specified).

#
# PYTHON_PLATFORM   - Python's idea of the OS release.
#             This is faked with ${OPSYS} and ${OSREL} until we
#             find out how to delay defining a variable until
#             after a certain target has been built.
#
# PYTHON_PKGNAMEPREFIX
#           - Use this as a ${PKGNAMEPREFIX} to distinguish
#             packages for different Python versions.
#             default: py${PYTHON_SUFFIX}-
#
# Using USES=python.mk also will add some useful entries to PLIST_SUB:

#
# Deprecated variables, which exist for compatibility and will be removed
# soon:
#
# PYTHON_DEFAULT_VERSION
# PYTHON2_DEFAULT_VERSION
# PYTHON3_DEFAULT_VERSION
#           - Deprecated, use PYTHON[2,3]_DEFAULT instead,
#             see bsd.default-versions.mk
#
# PYTHON_PKGNAMESUFFIX
#           - Deprecated, use PYTHON_PKGNAMEPREFIX instead
#             default: -py${PYTHON_SUFFIX}
