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!

149 # @FUNCTION: eshopts_push
150 # @USAGE: [options to `set` or `shopt`]
151 # @DESCRIPTION:
152 # Often times code will want to enable a shell option to change code behavior.
153 # Since changing shell options can easily break other pieces of code (which
154 # assume the default state), eshopts_push is used to (1) push the current shell
155 # options onto a stack and (2) pass the specified arguments to set.
156 #
157 # If the first argument is '-s' or '-u', we assume you want to call `shopt`
158 # rather than `set` as there are some options only available via that.
159 #
160 # A common example is to disable shell globbing so that special meaning/care
161 # may be used with variables/arguments to custom functions. That would be:
162 # @CODE
163 # eshopts_push -s noglob
164 # for x in ${foo} ; do
165 # if ...some check... ; then
166 # eshopts_pop
167 # return 0
168 # fi
169 # done
170 # eshopts_pop
171 # @CODE
172 eshopts_push() {

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

270 # @FUNCTION: epatch
271 # @USAGE: [options] [patches] [dirs of patches]
272 # @DESCRIPTION:
273 # epatch is designed to greatly simplify the application of patches. It can
274 # process patch files directly, or directories of patches. The patches may be
275 # compressed (bzip/gzip/etc...) or plain text. You generally need not specify
276 # the -p option as epatch will automatically attempt -p0 to -p5 until things
277 # apply successfully.
278 #
279 # If you do not specify any patches/dirs, then epatch will default to the
280 # directory specified by EPATCH_SOURCE.
281 #
282 # Any options specified that start with a dash will be passed down to patch
283 # for this specific invocation. As soon as an arg w/out a dash is found, then
284 # arg processing stops.
285 #
286 # When processing directories, epatch will apply all patches that match:
287 # @CODE
288 # if ${EPATCH_FORCE} != "yes"
289 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
290 # else
291 # *.${EPATCH_SUFFIX}
292 # @CODE
293 # The leading ?? are typically numbers used to force consistent patch ordering.
294 # The arch field is used to apply patches only for the host architecture with
295 # the special value of "all" means apply for everyone. Note that using values
296 # other than "all" is highly discouraged -- you should apply patches all the
297 # time and let architecture details be detected at configure/compile time.
298 #
299 # If EPATCH_SUFFIX is empty, then no period before it is implied when searching
300 # for patches to apply.
301 #
302 # Refer to the other EPATCH_xxx variables for more customization of behavior.

566 # @DESCRIPTION:
567 # Applies user-provided patches to the source tree. The patches are
568 # taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/, where the first
569 # of these three directories to exist will be the one to use, ignoring
570 # any more general directories which might exist as well. They must end
571 # in ".patch" to be applied.
572 #
573 # User patches are intended for quick testing of patches without ebuild
574 # modifications, as well as for permanent customizations a user might
575 # desire. Obviously, there can be no official support for arbitrarily
576 # patched ebuilds. So whenever a build log in a bug report mentions that
577 # user patches were applied, the user should be asked to reproduce the
578 # problem without these.
579 #
580 # Not all ebuilds do call this function, so placing patches in the
581 # stated directory might or might not work, depending on the package and
582 # the eclasses it inherits and uses. It is safe to call the function
583 # repeatedly, so it is always possible to add a call at the ebuild
584 # level. The first call is the time when the patches will be
585 # applied.
586 #
587 # Ideally, this function should be called after gentoo-specific patches
588 # have been applied, so that their code can be modified as well, but
589 # before calls to e.g. eautoreconf, as the user patches might affect
590 # autotool input files as well.

1189 #
1190 # A temporary hack until portage properly supports DEPENDing on USE
1191 # flags being enabled in packages. This will check to see if the specified
1192 # DEPEND atom was built with the specified list of USE flags. The
1193 # --missing option controls the behavior if called on a package that does
1194 # not actually support the defined USE flags (aka listed in IUSE).
1195 # The default is to abort (call die). The -a and -o flags control
1196 # the requirements of the USE flags. They correspond to "and" and "or"
1197 # logic. So the -a flag means all listed USE flags must be enabled
1198 # while the -o flag means at least one of the listed IUSE flags must be
1199 # enabled. The --hidden option is really for internal use only as it
1200 # means the USE flag we're checking is hidden expanded, so it won't be found
1201 # in IUSE like normal USE flags.
