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 swegener 1.286 #
15 vapier 1.283 # Due to the nature of this eclass, some functions may have maintainers
16     # different from the overall eclass!

152 vapier 1.330 # @USAGE: [options to `set` or `shopt`]
153 vapier 1.322 # @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 vapier 1.330 # 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 vapier 1.322 # 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 vapier 1.376 # eshopts_push -s noglob
166 vapier 1.322 # for x in ${foo} ; do

258 vapier 1.325 # @FUNCTION: epatch
259     # @USAGE: [patches] [dirs of patches]
260     # @DESCRIPTION:
261     # epatch is designed to greatly simplify the application of patches. It can
262     # process patch files directly, or directories of patches. The patches may be
263     # compressed (bzip/gzip/etc...) or plain text. You generally need not specify
264     # the -p option as epatch will automatically attempt -p0 to -p5 until things
265     # apply successfully.
266 azarah 1.2 #
267 vapier 1.325 # If you do not specify any options, then epatch will default to the directory
268     # specified by EPATCH_SOURCE.
269 azarah 1.2 #
270 vapier 1.325 # When processing directories, epatch will apply all patches that match:

273 vapier 1.325 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
274     # else
275     # *.${EPATCH_SUFFIX}
276     # @CODE
277     # The leading ?? are typically numbers used to force consistent patch ordering.
278     # The arch field is used to apply patches only for the host architecture with
279     # the special value of "all" means apply for everyone. Note that using values
280     # other than "all" is highly discouraged -- you should apply patches all the
281     # time and let architecture details be detected at configure/compile time.
282 azarah 1.2 #
283 vapier 1.325 # If EPATCH_SUFFIX is empty, then no period before it is implied when searching
284     # for patches to apply.

517     # of these three directories to exist will be the one to use, ignoring
518     # any more general directories which might exist as well.
519     #
520     # User patches are intended for quick testing of patches without ebuild
521     # modifications, as well as for permanent customizations a user might
522     # desire. Obviously, there can be no official support for arbitrarily
523     # patched ebuilds. So whenever a build log in a bug report mentions that
524     # user patches were applied, the user should be asked to reproduce the
525     # problem without these.
526     #
527     # Not all ebuilds do call this function, so placing patches in the
528     # stated directory might or might not work, depending on the package and
529     # the eclasses it inherits and uses. It is safe to call the function
530     # repeatedly, so it is always possible to add a call at the ebuild
531     # level. The first call is the time when the patches will be
532     # applied.
533     #
534     # Ideally, this function should be called after gentoo-specific patches
535     # have been applied, so that their code can be modified as well, but
