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!

87 vapier 1.322 # @FUNCTION: eshopts_push
88 vapier 1.330 # @USAGE: [options to `set` or `shopt`]
89 vapier 1.322 # @DESCRIPTION:
90     # Often times code will want to enable a shell option to change code behavior.
91     # Since changing shell options can easily break other pieces of code (which
92     # assume the default state), eshopts_push is used to (1) push the current shell
93     # options onto a stack and (2) pass the specified arguments to set.
94     #
95 vapier 1.330 # If the first argument is '-s' or '-u', we assume you want to call `shopt`
96     # rather than `set` as there are some options only available via that.
97     #
98 vapier 1.322 # A common example is to disable shell globbing so that special meaning/care
99     # may be used with variables/arguments to custom functions. That would be:
100     # @CODE
101     # eshopts_push -o noglob
102     # for x in ${foo} ; do
103     # if ...some check... ; then
104     # eshopts_pop
105     # return 0
106     # fi
107     # done
108     # eshopts_pop
109     # @CODE
110     eshopts_push() {
111     # have to assume __ESHOPTS_SAVE__ isn't screwed with
112     # as a `declare -a` here will reset its value
113     local i=${#__ESHOPTS_SAVE__[@]}
114 vapier 1.330 if [[ $1 == -[su] ]] ; then
115     __ESHOPTS_SAVE__[$i]=$(shopt -p)

123 vapier 1.322 }
124    
125     # @FUNCTION: eshopts_pop
126     # @USAGE:

180 vapier 1.325 # @FUNCTION: epatch
181     # @USAGE: [patches] [dirs of patches]
182     # @DESCRIPTION:
183     # epatch is designed to greatly simplify the application of patches. It can
184     # process patch files directly, or directories of patches. The patches may be
185     # compressed (bzip/gzip/etc...) or plain text. You generally need not specify
186     # the -p option as epatch will automatically attempt -p0 to -p5 until things
187     # apply successfully.
188 azarah 1.2 #
189 vapier 1.325 # If you do not specify any options, then epatch will default to the directory
190     # specified by EPATCH_SOURCE.
191 azarah 1.2 #
192 vapier 1.325 # When processing directories, epatch will apply all patches that match:
193     # @CODE
194     # ${EPATCH_FORCE} == "yes"
195     # ??_${ARCH}_foo.${EPATCH_SUFFIX}
196     # else
197     # *.${EPATCH_SUFFIX}
198     # @CODE
199     # The leading ?? are typically numbers used to force consistent patch ordering.
200     # The arch field is used to apply patches only for the host architecture with
201     # the special value of "all" means apply for everyone. Note that using values
202     # other than "all" is highly discouraged -- you should apply patches all the
203     # time and let architecture details be detected at configure/compile time.
204 azarah 1.2 #
205 vapier 1.325 # If EPATCH_SUFFIX is empty, then no period before it is implied when searching
206     # for patches to apply.
