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!

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 -s noglob
166 # for x in ${foo} ; do
167 # if ...some check... ; then
168 # eshopts_pop
169 # return 0
170 # fi
171 # done
172 # eshopts_pop
173 # @CODE
174 eshopts_push() {
175 if [[ $1 == -[su] ]] ; then
176 estack_push eshopts "$(shopt -p)"

181 [[ $# -eq 0 ]] && return 0
182 set "$@" || die "${FUNCNAME}: bad options to set: $*"
183 fi
184 }
185
186 # @FUNCTION: eshopts_pop
187 # @USAGE:
188 # @DESCRIPTION:
189 # Restore the shell options to the state saved with the corresponding
190 # eshopts_push call. See that function for more details.
191 eshopts_pop() {

193 estack_pop eshopts s || die "${FUNCNAME}: unbalanced push"

232 # @DESCRIPTION:
233 # Options to pass to patch. Meant for ebuild/package-specific tweaking

266
267 # @FUNCTION: epatch
268 # @USAGE: [options] [patches] [dirs of patches]
269 # @DESCRIPTION:
270 # epatch is designed to greatly simplify the application of patches. It can
271 # process patch files directly, or directories of patches. The patches may be
272 # compressed (bzip/gzip/etc...) or plain text. You generally need not specify
273 # the -p option as epatch will automatically attempt -p0 to -p5 until things
274 # apply successfully.
275 #
276 # If you do not specify any patches/dirs, then epatch will default to the
277 # directory specified by EPATCH_SOURCE.
278 #
279 # Any options specified that start with a dash will be passed down to patch
280 # for this specific invocation. As soon as an arg w/out a dash is found, then
281 # arg processing stops.
282 #
283 # When processing directories, epatch will apply all patches that match:
284 # @CODE
285 # if ${EPATCH_FORCE} != "yes"
286 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
287 # else
288 # *.${EPATCH_SUFFIX}
289 # @CODE
290 # The leading ?? are typically numbers used to force consistent patch ordering.
291 # The arch field is used to apply patches only for the host architecture with
292 # the special value of "all" means apply for everyone. Note that using values
293 # other than "all" is highly discouraged -- you should apply patches all the
294 # time and let architecture details be detected at configure/compile time.
295 #
296 # If EPATCH_SUFFIX is empty, then no period before it is implied when searching
297 # for patches to apply.
298 #
299 # Refer to the other EPATCH_xxx variables for more customization of behavior.

554 # @DESCRIPTION:
555 # Applies user-provided patches to the source tree. The patches are
556 # taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
557 # of these three directories to exist will be the one to use, ignoring
558 # any more general directories which might exist as well. They must end
559 # in ".patch" to be applied.
560 #
561 # User patches are intended for quick testing of patches without ebuild
562 # modifications, as well as for permanent customizations a user might
563 # desire. Obviously, there can be no official support for arbitrarily
564 # patched ebuilds. So whenever a build log in a bug report mentions that
565 # user patches were applied, the user should be asked to reproduce the
566 # problem without these.
567 #
568 # Not all ebuilds do call this function, so placing patches in the
569 # stated directory might or might not work, depending on the package and
570 # the eclasses it inherits and uses. It is safe to call the function
571 # repeatedly, so it is always possible to add a call at the ebuild
572 # level. The first call is the time when the patches will be
573 # applied.
574 #
575 # Ideally, this function should be called after gentoo-specific patches
576 # have been applied, so that their code can be modified as well, but
577 # before calls to e.g. eautoreconf, as the user patches might affect
578 # autotool input files as well.

1174 # @DESCRIPTION:
1175 #
1176 # Deprecated: Use EAPI 2 use deps in DEPEND|RDEPEND and with has_version calls.
1177 #
1178 # A temporary hack until portage properly supports DEPENDing on USE
1179 # flags being enabled in packages. This will check to see if the specified
1180 # DEPEND atom was built with the specified list of USE flags. The
1181 # --missing option controls the behavior if called on a package that does
1182 # not actually support the defined USE flags (aka listed in IUSE).
1183 # The default is to abort (call die). The -a and -o flags control
1184 # the requirements of the USE flags. They correspond to "and" and "or"
1185 # logic. So the -a flag means all listed USE flags must be enabled
1186 # while the -o flag means at least one of the listed IUSE flags must be
1187 # enabled. The --hidden option is really for internal use only as it
1188 # means the USE flag we're checking is hidden expanded, so it won't be found
1189 # in IUSE like normal USE flags.
