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.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

22#
23# ecpu_check array_of_cpu_flags
24#
25# array_of_cpu_flags - An array of cpu flags to check against USE flags
26#
27# Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28# cpu flag that is not supported in their processor flags, it will warn the
29# user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30# obviously using different cpu flags than their own cpu ). Examples:
31#
32# CPU_FLAGS=(mmx mmx2 sse sse2)

151# @FUNCTION: eshopts_push
152# @USAGE: [options to `set` or `shopt`]
153# @DESCRIPTION:
154# Often times code will want to enable a shell option to change code behavior.
155# Since changing shell options can easily break other pieces of code (which
156# assume the default state), eshopts_push is used to (1) push the current shell
157# options onto a stack and (2) pass the specified arguments to set.
158#
159# If the first argument is '-s' or '-u', we assume you want to call `shopt`
160# rather than `set` as there are some options only available via that.
161#
162# A common example is to disable shell globbing so that special meaning/care
163# may be used with variables/arguments to custom functions. That would be:
164# @CODE
165# eshopts_push -o noglob
166# for x in ${foo} ; do
167# if ...some check... ; then

175# This function is for bulk patching, or in theory for just one 260# @FUNCTION: epatch
176# or two patches. 261# @USAGE: [patches] [dirs of patches]
262# @DESCRIPTION:
263# epatch is designed to greatly simplify the application of patches. It can
264# process patch files directly, or directories of patches. The patches may be
265# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
266# the -p option as epatch will automatically attempt -p0 to -p5 until things
267# apply successfully.
177# 268#
178# It should work with .bz2, .gz, .zip and plain text patches. 269# If you do not specify any options, then epatch will default to the directory
179# Currently all patches should be the same format. 270# specified by EPATCH_SOURCE.
180# 271#
181# You do not have to specify '-p' option to patch, as it will 272# When processing directories, epatch will apply all patches that match:
182# try with -p0 to -p5 until it succeed, or fail at -p5. 273# @CODE
183# 274# if ${EPATCH_FORCE} != "yes"
184# Above EPATCH_* variables can be used to control various defaults,
185# bug they should be left as is to ensure an ebuild can rely on
186# them for.
187#
188# Patches are applied in current directory.
189#
190# Bulk Patches should preferibly have the form of:
191#
192# ??_${ARCH}_foo.${EPATCH_SUFFIX} 275# ??_${ARCH}_foo.${EPATCH_SUFFIX}
276# else
277# *.${EPATCH_SUFFIX}
278# @CODE
279# The leading ?? are typically numbers used to force consistent patch ordering.
280# The arch field is used to apply patches only for the host architecture with
281# the special value of "all" means apply for everyone. Note that using values
282# other than "all" is highly discouraged -- you should apply patches all the
283# time and let architecture details be detected at configure/compile time.
193# 284#
194# For example: 285# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
286# for patches to apply.
195# 287#
196# 01_all_misc-fix.patch.bz2 288# Refer to the other EPATCH_xxx variables for more customization of behavior.
197# 02_sparc_another-fix.patch.bz2
198#
199# This ensures that there are a set order, and you can have ARCH
200# specific patches.
201#
202# If you however give an argument to epatch(), it will treat it as a
203# single patch that need to be applied if its a file. If on the other
204# hand its a directory, it will set EPATCH_SOURCE to this.

524# desire. Obviously, there can be no official support for arbitrarily
