# @BLURB: A simple eclass to build Python packages using distutils. |
| 13 |
# @DESCRIPTION: |
| 14 |
# A simple eclass providing functions to build Python packages using |
| 15 |
# the distutils build system. It exports phase functions for all |
| 16 |
# the src_* phases. Each of the phases runs two pseudo-phases: |
| 17 |
# python_..._all() (e.g. python_prepare_all()) once in ${S}, then |
| 18 |
# python_...() (e.g. python_prepare()) for each implementation |
| 19 |
# (see: python_foreach_impl() in python-r1). |
| 20 |
# |
| 21 |
# In distutils-r1_src_prepare(), the 'all' function is run before |
| 22 |
# per-implementation ones (because it creates the implementations), |
| 23 |
# per-implementation functions are run in a random order. |
| 24 |
# |
| 25 |
# In remaining phase functions, the per-implementation functions are run |
| 26 |
# before the 'all' one, and they are ordered from the least to the most |
| 27 |
# preferred implementation (so that 'better' files overwrite 'worse' |
| 28 |
# ones). |
| 29 |
# |
| 30 |
# If the ebuild doesn't specify a particular pseudo-phase function, |
| 31 |
# the default one will be used (distutils-r1_...). Defaults are provided |
| 32 |
# for all per-implementation pseudo-phases, python_prepare_all() |
| 33 |
# and python_install_all(); whenever writing your own pseudo-phase |
| 34 |
# functions, you should consider calling the defaults (and especially |
| 35 |
# distutils-r1_python_prepare_all). |
| 36 |
# |
| 37 |
# Please note that distutils-r1 sets RDEPEND and DEPEND unconditionally |
| 38 |
# for you. |
| 39 |
# |
| 40 |
# Also, please note that distutils-r1 will always inherit python-r1 |
| 41 |
# as well. Thus, all the variables defined and documented there are |
| 42 |
# relevant to the packages using distutils-r1. |

# @ECLASS-VARIABLE: PATCHES |
| 63 |
# @DEFAULT_UNSET |
| 64 |
# @DESCRIPTION: |
| 65 |
# An array containing patches to be applied to the sources before |
| 66 |
# copying them. |
| 67 |
# |
| 68 |
# If unset, no custom patches will be applied. |
| 69 |
# |
| 70 |
# Please note, however, that at some point the eclass may apply |
| 71 |
# additional distutils patches/quirks independently of this variable. |
| 72 |
# |
| 73 |
# Example: |
| 74 |
# @CODE |
| 75 |
# PATCHES=( "${FILESDIR}"/${P}-make-gentoo-happy.patch ) |
| 76 |
# @CODE |
| 77 |
|
| 78 |
# @ECLASS-VARIABLE: DOCS |
| 79 |
# @DEFAULT_UNSET |
| 80 |
# @DESCRIPTION: |
| 81 |
# An array containing documents installed using dodoc. The files listed |
| 82 |
# there must exist in the directory from which |
| 83 |
# distutils-r1_python_install_all() is run (${S} by default). |
| 84 |
# |
| 85 |
# If unset, the function will instead look up files matching default |
| 86 |
# filename pattern list (from the Package Manager Specification), |
| 87 |
# and install those found. |
| 88 |
# |
| 89 |
# Example: |
| 90 |
# @CODE |
| 91 |
# DOCS=( NEWS README ) |
| 92 |
# @CODE |
| 93 |
|
| 94 |
# @ECLASS-VARIABLE: HTML_DOCS |
| 95 |
# @DEFAULT_UNSET |
| 96 |
# @DESCRIPTION: |
| 97 |
# An array containing documents installed using dohtml. The files |
| 98 |
# and directories listed there must exist in the directory from which |
| 99 |
# distutils-r1_python_install_all() is run (${S} by default). |
| 100 |
# |
| 101 |
# If unset, no HTML docs will be installed. |
| 102 |
# |
| 103 |
# Example: |
| 104 |
# @CODE |
| 105 |
# HTML_DOCS=( doc/html/ ) |

# @CODE |
| 107 |
|
| 108 |
# @ECLASS-VARIABLE: DISTUTILS_IN_SOURCE_BUILD |
| 109 |
# @DEFAULT_UNSET |
| 110 |
# @DESCRIPTION: |
| 111 |
# If set to a non-null value, in-source builds will be enabled. |
| 112 |
# If unset, the default is to use in-source builds when python_prepare() |
| 113 |
# is declared, and out-of-source builds otherwise. |
| 114 |
# |
| 115 |
# If in-source builds are used, the eclass will create a copy of package |
| 116 |
# sources for each Python implementation in python_prepare_all(), |
| 117 |
# and work on that copy afterwards. |
| 118 |
# |
| 119 |
# If out-of-source builds are used, the eclass will instead work |
| 120 |
# on the sources directly, prepending setup.py arguments with |
| 121 |
# 'build --build-base ${BUILD_DIR}' to enforce keeping & using built |
| 122 |
# files in the specific root. |
