6# @MAINTAINER:
7# base-system@gentoo.org
8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
4# 14#
5# This eclass is for general purpose functions that most ebuilds 15# Due to the nature of this eclass, some functions may have maintainers
6# have to implement themselves. 16# different from the overall eclass!
7#
8# NB: If you add anything, please comment it!

111# This function is for bulk patching, or in theory for just one 182# @FUNCTION: epatch
112# or two patches. 183# @USAGE: [patches] [dirs of patches]
184# @DESCRIPTION:
185# epatch is designed to greatly simplify the application of patches. It can
186# process patch files directly, or directories of patches. The patches may be
187# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
188# the -p option as epatch will automatically attempt -p0 to -p5 until things
189# apply successfully.
113# 190#
114# It should work with .bz2, .gz, .zip and plain text patches. 191# If you do not specify any options, then epatch will default to the directory
115# Currently all patches should be the same format. 192# specified by EPATCH_SOURCE.
116# 193#
117# You do not have to specify '-p' option to patch, as it will 194# When processing directories, epatch will apply all patches that match:
118# try with -p0 to -p5 until it succeed, or fail at -p5. 195# @CODE
119# 196# ${EPATCH_FORCE} == "yes"
120# Above EPATCH_* variables can be used to control various defaults,
121# bug they should be left as is to ensure an ebuild can rely on
122# them for.
123#
124# Patches are applied in current directory.
125#
126# Bulk Patches should preferibly have the form of:
127#
128# ??_${ARCH}_foo.${EPATCH_SUFFIX} 197# ??_${ARCH}_foo.${EPATCH_SUFFIX}
198# else
199# *.${EPATCH_SUFFIX}
200# @CODE
201# The leading ?? are typically numbers used to force consistent patch ordering.
202# The arch field is used to apply patches only for the host architecture with
203# the special value of "all" means apply for everyone. Note that using values
204# other than "all" is highly discouraged -- you should apply patches all the
205# time and let architecture details be detected at configure/compile time.
129# 206#
130# For example: 207# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
208# for patches to apply.
131# 209#
132# 01_all_misc-fix.patch.bz2 210# Refer to the other EPATCH_xxx variables for more customization of behavior.
133# 02_sparc_another-fix.patch.bz2
134#
135# This ensures that there are a set order, and you can have ARCH
136# specific patches.
137#
138# If you however give an argument to epatch(), it will treat it as a
139# single patch that need to be applied if its a file. If on the other
140# hand its a directory, it will set EPATCH_SOURCE to this.
